Today’s National Forecast

Weather Forecast map

A fast-moving low pressure system will move off the Mid-Atlantic/Northeast coast this morning, and areas of rain and snow across the Northeast come to an end by late morning. Strong and gusty winds may persist across portions of the Northeast into early evening, however. A second low pressure system, following a similar track to the one moving offshore, will cross the Upper Midwest and Great Lakes today and tonight, bringing another round of rain and snow. This system will once again spread snow into the Northeast by early Monday morning, with rain farther south across much of the Mid-Atlantic.

Rain showers will return to the Pacific Northwest by this evening as a cold front approaches the region. The front will move into the Intermountain West by Monday morning, with rain changing to snow across the Cascades as the front moves inland. This system will bring a mix of mountain snow and valley rain to the Intermountain West and central/northern Rockies through the day on Monday, before moving into the northern plains Tuesday night. Snow will be possible in association with this system by early Monday morning across portions of the Upper Midwest, with scattered showers and thunderstorms farther south across the central plains. Temperatures will generally be above average across much of the western and central U.S. today, with afternoon high temperatures expected to be 10 to 20 degrees above average.

Current Model Analysis

6 hour model

High pressure is continuing to dominate the West coast and mountain regions with only a few showers near Oregon and Idaho, the cold front over the east coast has moved off shore but a rapidly developing low will impact the Northeast beginning as rain before an artic front changes everything over to snow. The very warm ground will limit accumulations in some places but the potential for thunder snow storms and accumulation rates of up to 2 inches an hour could make the snow pile up very quickly in places.

18 hour model

By Sunday afternoon, 2 clipper systems will be the only precipitation in the lower 48. Snow will be quickly diminishing around the Boston area as snow begins to pick up from International Falls to near Detroit. Some showers and thunderstorms could be an issue near Miami as lingering instability remains just off shore with the cold front.

36 hour model

By early Monday, the second clipper system should be moving into the Northeast bringing snow and rain from Indiana to New York City over to the Atlantic coast of New England. A candian high pressure system will bring some unseasonably cold air down for the Great Lakes region as a new low pressure system beging to enter the Pacific Northwest.

Severe Thunderstorms are not expected Sunday

***Analysis***

The strong cold front that has been bringing severe weather to the country will move off shore today with strong storms in North Carolina and Virginia this morning that should end around mid-day.   The frontal boundary extends down to Florida and will reach the Central portions of the state this afternoon causing some strong to potentially severe storms.  The next system, which may bring snow to areas as far East as Boston, will have a very strong cold front trailing it that could cause some storms in Indiana and Ohio but conditions are not good for significant development.
