Major Winter Storm Update

Severe watches

For this major winter storm update, All winter weather warnings have been removed from Arkansas and Missouri with only a few remaining in Mississippi as the storm begins to pull east. Additional Warnings and Advisories have been added further Northeast up into Connecticut, Rhode Island and Massachusetts.   All other Warnings and advisories remain in effect for today as the primary low begins to transition to its secondary location.  This change will bring in the snowfall to the Eastern Carolinas bringing it almost to the coast line by Saturday morning.  As a reminder for all who have so far been disappointed by the situation they find themselves in, this storm is far from over and will be impacting your regions this evening and overnight tonight.  Further north you will see snow move in even later than that as the storm pulls to the Northeast.   The Southern New England area won’t see its first flakes until mid morning on Saturday.

The Blizzard Watch for Philadelphia through the NYC metro areas has been upgraded to a Blizzard Warning.  The previous forecast for these areas holds with totals now expected around the higher ends of the limits as the storm appears to be moving slightly further north than the models had yesterday, but as I had been concerned about all along.   This is why I did not put out totals for Southern New England last night.  I was not confident that the models had the situation correctly profiled and by this morning my concern was completely proven correct.

rain and snow

To reiterate the Southern New England update I gave on Facebook,

BLIZZARD WARNING: for the Island of Martha’s Vineyard and Block Island from 1 PM Saturday until 7 AM Sunday. 8-12 inches of snow is expected to fall in this area and strong winds up to 55 mph,  will create blizzard conditions in this area. Coastal Flooding is expected to be an issue on these winds.

Winter Storm Warnings have been issued for the South Coast of Massachusetts, Rhode Island, and Connecticut including Cape Cod and Nantucket, beginning at 4 AM Saturday and ending 7 AM Sunday. 6-10 inches of snow is expected in this area. Snow will begin by mid-morning and intensify in the early afternoon and evening with snow fall rates around 1 inch per hour. Gusty winds of up to 50 mph will combine with high snowfall rates to bring near blizzard conditions at times before midnight with visibilities under half a mile.

A Winter Storm Warning has also been issued for Coastal Plymouth County and Interior Southern Rhode Island for 4-8 inches of snow. Snow will begin by mid-morning and taper off after midnight. Heavy snow and wind gusts up to 45 mph will bring visibilities down to under a mile during the late afternoon and evening on Saturday.

Winter Weather Advisories have been issued for the remainder of Plymouth and Bristol County including Brockton and for Northern Rhode Island for 3-6 inches of snow. Winds in this area will gust to 35 mph and reduce visibilities for a time.

These snowfall totals can be very hit or miss at this time. The cut off for snow from this storm is very sharp and a shift in the track of just 50 miles can dramatically alter the snowfall totals here. I will keep on this system for the remainder of the day and will be up all night tracking the very latest in details

Snow will leave the Northeast Sunday morning and early afternoon.

Major Winter Storm, Mid-Atlantic and Northeast

When we last left this subject, we had Tornadoes, snow, ice, and me pulling my hair out over the newest NAM model giving Boston a foot of snow.    Oh New England, what am I going to do with you?

rain and snow

On to Virginia and the Mid Atlantic!!

West Virginia and Virginia:

Moving north from my last post into Virginia, only the Southeast portions of the state will get straight rain, most areas will have cold air being brought down for what could be a historic blizzard for portions of the state.

Blizzard Warnings are in effect for Charles, St. Mary, Calvert, Prince William, Manasas, Stafford, Spotsylvania and King George Counties.  This warning is from 1 PM Friday to 6 AM Sunday.  Heavy snow will begin Friday afternoon and while it may mix with sleet for a time east if I-95, It will change back to all snow Saturday afternoon.  18 to 24 inches of snow are expected in this region with the lower amounts near the bay.  Winds will be gusting up to 55 mph in  this area and I would strongly advise that no one in this region head out Friday night.

Winter Storm Warnings are in effect from Southeast West Virginia along and north of highway 460 towards Lynchburg and on to Appomattox.  16 to 24 inches of snow will fall in this area with the highest amounts in the Blue Ridge region. Snow will be heaviest during the mid-morning through midafternoon hours and gusty winds will reduce visibilities down to 0 in the higher terrain.

Further South and East, Central Virginia and the Interior Northern Neck region will have snow picking up late Friday morning and getting heavy at times during the afternoon and evening.  Sleet and Freezing rain may mix in some as the original low pressure system moves the west of this area before dying out as the secondary pushes north.  This changeover and possible change to rain on Saturday will help keep totals down in the 7-15 inch range with the higher totals in the Piedmont regions of central Virginia to the West and North of Richmond.

Down in the Southeast corner of the state, interior regions near Emporia, Wakefield and Williamsburg will see even lesser amounts as sleet and rain mix in with the snow.  After the mix, this area will turn to rain and have seen 2-5 inches of snow.  Though a fresh coating to an inch may occur as the precipitation changes back to snow on the backside of the low.

Heading back to West Virginia,  Central and Northwest areas of the state and including Western portions of Maryland from Hagerstown West, are set to see 18-24 inches of snow between Friday afternoon and Saturday evening.  Snow will be at its heaviest overnight Friday with strong Northeast winds reducing visibilities and making some roads in the mountains impassable.

Maryland D.C. and Delaware

Jumping over to the Eastern shore of Maryland.  The Southern tip of the Eastern shore will see snow begin Early Friday afternoon, but for those in Dorchester County, the warm oceans will mix in sleet and freezing rain before changing over to all rain for a time but additional snow accumulations are expected by Saturday afternoon and into Saturday night, leaving the county with about 6-12 inches of snow.  Even lower amounts are expected towards Wicomico and Somerset counties, as well as Inland Sussex County in Maryland, and Cape May County and Coastal Ocean County in New Jersey, where 2 to 6 inches may fall and Winter Storm Watches are in effect.  Sleet and then Rain will be a major factor in this area as temperatures climb into the upper 30s late Friday and stay that way through Saturday afternoon.  Worcester County will see very little snow and ice and accumulations of less than 2 inches are expected before the changeover to rain in this area.

For the remainder of the Eastern Shore and Kent and New Castle Delaware, 10 to 16 inches of snow is possible from Friday night into Sunday morning.  Blizzard conditions are possible during the day on Saturday as heavy snow, high winds, and cold temperatures combine before tapering off.

For the remainder of Maryland and D.C, Blizzard Warnings are in effect from 3 PM Friday until 6 AM Sunday, expect starting at 6 PM near Baltimore.   The Eastern Suburbs of DC and Baltimore can expect 18 to 24 inches of snow as sleet mixes in along and east of 95, but the western suburbs are in the bullseye as 24 to 30 inches of snow will fall where sleet does not mix with the snow.  Winds will gust to 50 mph creating whiteout conditions overnight Friday.  Anyone living in this area will want to be off the roads by early to mid-Friday afternoon.

rain and snow

Pennsylvania, New Jersey and New York:

Much of the action with this system will take place in Southern and Eastern Pennsylvania.

In the West, Winter Weather Advisories are in effect for Washington, Westmoreland, Allegheny, and Indiana Counties including Pittsburgh for 4-6 inches of snow beginning on Friday afternoon and ending late Saturday afternoon.  Just east of there, Cambria, Blair, Huntington, Mifflin, Juniata and Schuylkill Counties are under Winter Storm Watches for 4-8 inches of snow during the same time period.  From Greene County over to York County and up to Dauphin and Lebanon Counties, Winter Storm Warnings are in effect for 6 to 12 inches of snow with as much as 24 inches along the Maryland border in places.

The bullseye region for here is from Philadelphia down to just inland of Atlantic City up through Trenton, Newark, New York City and out to Long Island.  Blizzard Watches are in effect for 8-16 inches of snow.  Less by the coastlines and more inland.  Blizzard conditions are possible during the day and evening on Saturday as heavy snow, winds as high as 40 mph, and cold temperatures combine before tapering off.

For Counties further inland, a line from the city of Reading, through Allentown and Morristown to West Milford and into Peekskill New York and the rest of the Lower Hudson Valley, Winter Storm Watches are in effect for 4-10 inches of snow beginning late on Friday or Early Saturday before tapering off Sunday morning.  This snow is expected to be very heavy and wet which reduces the chances of blowing and drifting snow.

New England:

Data on New England snowfall continues to change by the hour.  The gradient of snowfall in this location is massive and a difference of just 20 miles in the track of the storm can be the difference between no snow and half a foot.  Model outputs from earlier today gave Providence a foot of snow while giving Boston less than an inch and model data on whether or not this region will get hit is all over the place.

close shave

What I can tell you is this, Maine, Vermont and New Hampshire are simply too far north to get in on this system.  The real question, and I do not yet have a good answer for readers in these locations, is what will happen in Southern New England. Any snowfall that does occur here will not arrive until Saturday afternoon and would taper off late Sunday.  So I will be up bright and early to begin looking at the 6Z and 12 Z runs of the models.  Consensus or not this region will have a forecast by Friday.

 

Please be aware that strong winds and coastal flooding will be a risk from North Carolina all the way through New England on the astronomically high tide.

 

Thank you for sticking with us on this incredibly busy day.  We will see you bright and early Friday.

Major Winter Storm Starts Across The South

snowstorm

A major winter storm is in the process of bringing a little bit of everything with a Tornado watch issued for through parts of Texas, Louisiana and Mississippi and winter weather warnings from Arkansas and Kansas all the way to New York City across 19 different states with snow or rain falling in 24 states. A potentially record breaking blizzard is expected to hit the mid-Atlantic and fall just short of hitting New England. Currently, locations under winter weather advisories are also under Severe Thunderstorm warnings and the tornado watch box for today is adjacent to counties that have winter weather advisories issued for later on today. It’s important for those who are in the worse affected areas to prepare themselves for what’s about to hit them. Do the basics like have a home safety kit, have enough food and water for at least 3 days, etc. You should also act fast after the storm has passed, checking your property for any damage it sustained. If you need to get roofing howard county md repairs after your roof was damaged in the storm then make sure you get it repaired quickly before it causes water damage. If you are a lover of dogs and enjoy taking your furry family member for walks regularly, we’d advise you to keep your dog dry as consistent wet fur for dogs can lead to illness, also it makes keeping home tidier and dry, easy.

A period of light to moderate snow is possible but the showers and squalls in this region are quickly diminishing. Accumulations of an inch are possible where these showers hold together with maybe 3-4 inches in the extreme Southeast corner of the state. As warm air begins to move back in at the surface this afternoon, patchy freezing drizzle is possible as the system pulls away. This region missed out on the storm for the most part as it developed too far to the south and east but the system will make the evening commute hazardous in many areas in this region none the less.

Arkansas and Northern Louisiana:

A Winter Weather Advisory has been issued for the following Counties: Marion, Baxter, Fulton, Izard, Sharp, Randolph, Searcy, Stone Pope, Van Buren, Conway, Yell, Montgomery, Pike, Clark, Ouachita, Calhoun and Bradley.

Snow will fall more heavily for a time in the Eastern Central to Southeastern sections of this watch area but more rain will fall the further south you go and will keep amounts slightly lower in Louisiana and extreme Southeast Arkansas but the east central portion of the state could see as much as a foot of snow as heavy snow moves in towards the end of the storm.

Map valid for Friday morning

gap

Per the map , you can see precipitation moving into the Southeastern states as well as Kentucky, and towards the Mid-Atlantic.

Mississippi, Alabama, Tennessee, Kentucky, Illinois, Indiana Ohio and West Virginia:

In Mississippi, North of Warren, Yazoo, Holmes, Attala, Winston and Noxubee, Winter Storm Warnings are in effect. More snow will fall in the western portion of the state where up to a foot of snow could fall as the cold air wraps around the back of the system. 3-6 inches will fall around Jackson with amounts dropping to 1-3 as you go toward the Alabama state line. For an interesting fun note, Warren County is currently under a Tornado Watch and then under the winter weather advisory for later on. Anyone for a tornadic thunder snow storm?

In Alabama, north of Pickens, Tuscaloosa, Jefferson, Shelby, Talladega, Clay and Cleburne Counties,

Winter Weather Advisories are in effect for an inch to 2 inches of snow. Rain will dominate the precipitation in this Alabama as the storm moves north and bring warm gulf air into the region but a late changeover to snow is possible for many areas as cold air wraps around the backside of the storm as it moves east. Accumulations are expected to be light but some sleet could fall during the transition as cold air at the surface moves in quicker than cold air aloft.

For Tennessee, every county in the state is under a Winter Weather Alert of some type. The middle of the state is under Winter Weather Advisories for 1-3 inches of snow. This area will also be impacted by the warm gulf air moving up into the region as the storm moves to the Northeast. After the initial low dissipates, the cold air coming in on the backside of the system will allow for a period of sleet and snow to occur and bring light accumulations to the area. In Western Tennessee, cold air will move in quicker as the storm stays south of Memphis and an area bounded by the state line towards Nashville will see amounts ranging from 4 inches upwards to a foot along the state line. Eastern portions of the state will see slightly higher amounts with 3-6 inches possible as precipitation begins as some snow and ice before changing to rain and then back to snow.

For Massac, Pope and Harden Counties in Illinois, Freezing rain is a major threat up to 2 tenths of an inch of freezing rain may fall with 3-6 inches of snow slated to fall.

The entire state of Kentucky is under winter weather warnings as freezing rain and snow are expected to accumulate through most of the state. Freezing rain accretion will be lower further east with a trace up to 2 tenths of an inch near Illinois. Nearly the entire state can expect at least 3 inches of snow with a swath from Louisville South expecting higher amounts throughout the entire state up towards 6 to 12 inches of snow. Eastern portions of the state as you approach the Appalachians will see 12-24 inches through the central part of the state.

In Indiana, Vandenburg, Warrick, Spencer, Dubois, Perry, Crawford, Orange, Washington, Harrison, Floyd, Clark, Scott, Jefferson, Switzerland, Ohio Counties are under Winter Weather Advisories for 1 to 4 inches of snow. These areas are on the northern fringe of the precipitation shield and will not see as much snow as areas to the south in Kentucky. Some counties to the north if these will see some wintry precipitation but only minor accumulations are expected.

For Ohio, Hamilton, Clermont, Clinton, Fayette, Pickaway, Fairfield, Perry, Muskingum, Guernsey, Belmont, Noble, and Monroe are under Winter Weather Advisories for 1-4 inches of snow. Similar to Indiana, these counties are on the fringe of the precipitation and will not see as much.

Brown, Adams, Highland, Ross, Pike, Scioto, Lawrence, Jackson, Gallia, Meigs, Vinton, Athens, Hocking, and Washington in Ohio are under Winter Storm Warnings for 4-8 inches of snow. This region will miss the really heavy stuff to the south.

Georgia, South Carolina, North Carolina, and Florida:

Florida will be a state that sees all rain and it presently has very little in the way of storm activity with a lone Severe Thunderstorm Warning active at the time of this writing. Friday will be a different story as the Storm Prediction Center gives a slight risk of severe weather to Northern Florida and Southern Georgia. While Florida won’t see any snow, showers and thunderstorms can be expected across the entire state.

For Georgia, only light amounts of snow are expected with 1-3 inches of snow and some light icing for the northern part of the state. Winter Weather Advisories have been issued for anywhere north of a Carrollton to Jonesboro to Lexington line including Atlanta.

A Freezing rain advisory has been issued in South Carolina for a line from Timmonsville to just north of Conway on into Castle Hayne North Carolina. A Trace up to a tenth of an inch of ice is expected in this region. Only a coating of snow may fall in this area.

Further North and West in South and North Carolina, The Piedmont region up into the mountains and foothills, including Greenville-Spartanburg and the Charlotte metro area should expect a significant icing situation with up to half an inch of ice accretion in the area. 2-10 inches of snow will fall with the higher amounts in the mountains and the lower amounts on the Piedmont. This ice and snow, along with gusty winds greatly increases the risk of power outages and makes for very dangerous travel. Any preparations for this storm should be completed by tonight.

The coastal plain for North Carolina also has winter weather advisories issued until 11 AM Friday. There will be about a tenth of an inch of snow and some small sleet accumulations. This will be a mostly rain event for this area as the storm develops off the coast.
