It’s been a hyper-active spring storm season and the trend continues this afternoon & evening with the potential for severe thunderstorms. Isolated to scattered severe thunderstorms are expected to develop in northern Texas this afternoon before accelerating east-southeast into eastern Texas, Louisiana, and Mississippi this evening into the overnight hours. The thunderstorm complex will travel along the I-20 corridor. This complex of thunderstorms will have the capability to produce damaging winds, isolated tornadoes, and hail.
In fact, the damaging wind threat looks elevated along the I-20 corridor from northern Texas to central Mississippi with some significant wind gusts potentially up to 80 mph in some cases. A good number of quick-hitting tornado warnings within this line of storms is also possible this evening and tonight. Because of the numerous severe storms expected within this line of storms, an enhanced (orange – level 3/5) severe risk exists for the aforementioned areas with a slight (yellow – level 2/5) and marginal (dark green – level 1/5) severe risk surrounding the enhanced severe risk area.
If you live within the severe risk area, please stay weather aware!
A dangerous high-impact severe weather day is expected today for much of the South with the possibility of a tornado & severe outbreak. All the ingredients have come together to support a hyperactive severe weather day throughout the day today into the evening and nighttime hours. All modes of severe weather are possible including tornadoes, damaging winds, and hail. The main concern is the possibility of significant damaging winds and tornadoes and all indicators suggest some tornadoes could become strong or violent this afternoon & evening along with some enhanced damaging winds. There’s the possibility of EF3 – EF5 tornadoes from the Tennessee Valley & Mid-South into the Deep South along with severe storms producing damaging winds in excess of 75 mph. Join the Firsthand Weather Supporter Group.
Because of the substantial severe threat, the Storm Prediction Center has highlighted the entire region as a severe risk and has issued a moderate (red – level 4/5) severe risk for eastern Louisiana, eastern Arkansas, much of Mississippi, and western & central Alabama, western Tennessee, and the Florida Panhandle. Surrounding the moderate severe risk is an enhanced (orange – level 3/5), slight (yellow – level 2/5), and marginal (dark green – level 1/5) severe risk for the duration of today.
All severe risk areas have a chance to see all modes of severe weather. The greatest concern for tornadoes and widespread damaging winds is within and near the moderate and enhanced severe risk areas.
If you live in or near any of these severe risk areas, please keep a very close eye on the forecast. You want to have a plan in place to act immediately in case a warning is issued for your area, and you want to have reliable weather sources to receive timely, accurate weather warnings from.
Firsthand Weather is monitoring the potential for a multi-day severe weather event from Tuesday through Thursday ranging from the Southern Plains to the Mid-Atlantic. There’s increased concern for a potential severe & tornado outbreak on Wednesday for the Deep South & Mid-South. All the ingredients are coming together to support numerous thunderstorms that could be discrete in nature producing several tornadoes throughout the day Wednesday into the evening hours. While there are still some questions and the event is a few days out, it appears strong, violent tornadoes are possible from eastern Louisiana, southeastern Arkansas, Mississippi & western Alabama
Because of the appreciable severe threat on Wednesday, the Storm Prediction Center has already outlined parts of the South within a slight (yellow – level 2/5) & enhanced (orange – level 3/5) severe risk. It’s likely additional areas will be included & an upgrade to at least a moderate (level 4/5) severe risk will be issued over the coming days.
If you live in or near the severe risk area, please go ahead and begin planning for potentially significant severe weather on Wednesday. Have a plan in place a warning is issued for your area, know what to do if a warning is issued, and have reliable weather sources to receive these warnings & forecast updates from. Stay tuned!
Monday was a very active severe weather and tornado day for parts of the Southern Plains and the severe threat continues today (Tuesday). There have already been numerous Severe Thunderstorm Warnings and Tornado Warnings today for parts of the South and that is expected to continue this afternoon & evening with an uptick in the number & intensity of severe storms. The atmosphere will also become primed for tornadoes today some of which could become strong tornadoes (EF3-EF5). In fact, there’s already a Tornado Watch in effect for areas of the South. This Tornado Watch includes parts of southeastern Louisiana and much of Mississippi until 7 PM CDT. Additional Tornado Watches could be issued today.
Because of the severe threat, the Storm Prediction Center has outlined a severe risk area for today. There is a moderate (red – level 4/5), enhanced (orange – level 3/5), slight (yellow level 2/5), and marginal (dark green – 1/5) severe risk for parts of the South. The moderate severe risk includes southern Louisiana, central and southern Mississippi, and west-central Alabama; while the enhanced severe risk surrounds the moderate severe risk, including northern Mississippi and western Alabama. The severe risk will slowly shift from west to east across the risk area this afternoon & evening. A few severe storms & tornadoes could continue into the nighttime hours.
Within the severe risk areas, all modes of severe weather are possible. This includes tornadoes, hail, and wind. A few strong tornadoes cannot be ruled out. The favored areas to see strong tornadoes are the areas within and near the moderate and enhanced severe risk areas. If you live in or near the severe risk areas, please keep aware of the weather throughout the day, have reliable sources to receive updated warnings from, and have a plan in place to immediately act if a warning is issued.
The severe threat shifts to the Southeast, Carolinas, & Mid-Atlantic tomorrow (Wednesday).
Today is the first day of spring and spring-like thunderstorms are possible this week. The first outbreak of severe thunderstorms is possible Monday (3/21) and Tuesday (3/22) for parts of the Southern Plains & South. The severe risks include tornadoes, large hail, and damaging winds. A few of the tornadoes could be strong both Monday and Tuesday along with very large hail on Monday.
The Storm Prediction Center has highlighted an area on Monday for severe storms which includes southern Oklahoma, most of the heart of Texas, southwestern Arkansas, and western Louisiana for severe thunderstorms Monday afternoon, evening, and into the overnight hours (severe risk shifting from west to east). There’s an enhanced (orange) severe risk (level 3/5) for central and southeastern Texas.
The severe risk shifts east and continues on Tuesday. The Storm Prediction Center has highlighted an area on Tuesday for severe storms which includes southeastern Texas, southeastern Arkansas, Louisiana, Mississippi, Alabama, and the Florida Panhandle for severe thunderstorms throughout the day on Tuesday. The severe risk will shift from west to east from the morning hours (west of the Mississippi) into the afternoon & evening hours (east of the Mississippi) on Tuesday. There’s an enhanced (orange) severe risk (level 3/5) for central, southern & eastern Louisiana, central & southern Mississippi, and western Alabama with a moderate (red) severe risk (level 4/5) for southeastern Louisiana and central Mississipi.
Again, all modes of severe storms are possible including strong, violent tornadoes. Please keep aware of the weather over the coming days, have a plan in place in case a watch/warning is issued for your area, and have reliable weather sources to receive watch/warning information from.
A winter storm will impact parts of the South late Friday into Saturday. This storm system will deliver accumulating snow as far south as I-20 in parts of Texas, Louisiana, Mississippi, and Alabama. Ahead of the winter storm, winter weather alerts have gone up.
Within the Winter Storm Watch and Winter Weather Advisory, accumulating snow is possible. A general 1-3 inches of snow can be expected with isolated higher amounts possible for some areas. See more details on the winter storm here.
Firsthand Weather has talked about the wintry threat for parts of the South over the past few days but there’s also a severe thunderstorm and tornado risk Friday & Saturday for parts of the Southeast. Read more about the winter storm.
The Storm Prediction Center (SPC) has outlined an area of a marginal (level 1 of 5 – dark green), slight (level 2 of 5 – yellow), and enhanced (level 3 of 5 – orange) severe risk on Friday for parts of the Southeast. The area extends from Louisiana east to the Carolinas. Friday will be quite active for this region with several rounds of thunderstorms throughout the day. Severe weather is possible at any point Friday with an increasingly severe risk Friday evening into the overnight hours. All modes of severe weather are possible including tornadoes, damaging winds, and large hail. The tornado risk will be highest Friday night.
All areas within the risk areas will see a tornado potential but the highest potential for tornadoes will exist from the Florida Panhandle, southeastern Alabama, southern Georgia, northern Florida, and south-central South Carolina.
The severe risk will shift east overnight Friday into Saturday, thus, the SPC has outlined an area of a marginal (level 1 of 5 – dark green) and slight (level 2 of 5 – yellow) severe risk on Saturday for coastal parts of the Southeast. The area extends from Florida north to the Carolinas. Again, similar to Friday, all modes of severe weather are possible including tornadoes, damaging winds, and large hail.
If you live within the severe risk area, please keep a close eye on the forecast, have reliable sources to receive weather warnings from, and have a plan in place in case a warning is issued for your area.
The latest guidance today continues to show this potential for a quick-hitting rain/snow mixture chance Friday into Saturday (spreading west to east) from northern Texas, Oklahoma, Arkansas, southern Missouri, far northern Louisiana, Kentucky, Tennesee, northern & central Mississippi, northern & central Alabama, northern Georgia, Upstate South Carolina, and North Carolina. There are still many questions but confidence has increased from low confidence to moderate confidence in the potential for snow for parts of these aforementioned areas late week into the weekend.
The European model over the past several runs has consistently shown this possibility of snow for parts of the Southern Plains, Mid-South, Tennesee Valley, and South late Friday into early Saturday, spreading into the Mid-Atlantic & Northeast over the weekend. The image below shows the latest animated run of the model from Friday through Saturday. The blue depicts snow while the green depicts rain. The darker the color, the heavier the precipitation.
The American model, like the European model, over the past several runs has also consistently shown this possibility of snow for parts of the Southern Plains, Mid-South, Tennesee Valley, and South late Friday into early Saturday, spreading into the Mid-Atlantic & Northeast over the weekend. The image below shows the latest animated run of the model from Friday through Saturday. The blue depicts snow while the green depicts rain. The darker the color, the heavier the precipitation. Join the Firsthand Weather Supporter Group for more details.
Again, while this forecast is not set in stone, confidence continues to increase that parts of the South will see snow Friday night into Saturday morning. The favored areas (for our followers in the South) will be Tennessee, northern & central Mississippi, northern & central Alabama, northern Georgia, and western North Carolina.
It’s too early to dive into the accumulation potential at this point. We do feel comfortable saying it’s possible there could be light accumulations, but this doesn’t appear to be a major winter storm. Warm temperatures leading up to the event, a short duration of wintry precipitation, marginal surface temperatures, and the snow possibly mixing with rain should mitigate how much snow potentially accumulates. Stay tuned for updates & join the Firsthand Weather Supporter Group for more details!
Firsthand Weather is monitoring the potential for severe thunderstorms and wintry weather for parts of the South & Southeast this Friday and Saturday as an upper-level system sends a batch of Arctic air south into the lower-48. Ahead of this Arctic air mass, a warm, moist, unstable air mass will build across the South & Southeast later this week. As this cold front clashes with the unstable spring-like air mass, it will trigger a line of thunderstorms on Friday across the South. While early and with still some questions to be ironed out, it appears favorable wind shear and a developing surface area of low pressure could allow for thunderstorms to become strong, possibly severe on Friday including the possibility of isolated tornadoes.
The favored areas appear to be from eastern Texas, southern Arkansas, Louisiana, and Mississippi Friday afternoon and spreading east into Alabama, Georgia, and north Florida during the evening and overnight hours. It’s possible the severe threat continues on Saturday for eastern parts of Georgia, northern Florida, and the Carolinas. Currently, there is no severe risk area outlined by the Storm Prediction Center but this could change over the coming days. If you live in the aforementioned area, make sure you keep a close eye on the forecast and have a plan in place in case a warning is issued on Friday.
The next concern is the cold, Arctic air rushing into the South & Southeast late Friday into Saturday. This air will be quite chilly and subfreezing. This is important because it appears the developing surface area of low pressure could help pull in enough moisture into the colder, subfreezing air for a quick changeover to wet snow for parts of the South & Southeast late Friday into Saturday. It needs to be mentioned that there are a lot of questions with this set up and this is a low confidence forecast but the guidance does support the cold air and moisture to overlap long enough for wet snow for some areas during this timeframe. The favored areas are Oklahoma, northern Texas, Arkansas, and central & southern Missouri Friday; eventually spreading into northern Mississippi & western Tennessee overnight Friday; and eventually into the rest of central & eastern Tennesee, northern Alabama, northern Georgia, Kentucky, the mountains of North Carolina, and potentially Upstate South Carolina on Saturday morning. Join the Firsthand Weather Supporter Group.
It needs to reiterated that there are a lot of questions with this forecast, it’s low confidence, and snow is not a guarantee for the aforementioned areas, but models are suggesting this is a possibility and while confidence is low at this time, confidence is increasing some areas will see snow late Friday and Saturday. It’s too far out for accumulation forecasts but this will be monitored over the coming days.
Behind the cold front, quite chilly air will stick around for a couple of days with a widespread freeze for the South & Southeast this weekend so bring the pets inside and protect the plants.
Conditions are coming together for the possibility of severe storms from southeastern Oklahoma northeast into southern Missouri. These severe storms will have the capability to produce large hail, damaging winds, and tornadoes. Because of the tornado risk this afternoon & evening, a Tornado Watch has been issued for parts of Arkansas, Missouri, and Oklahoma until 8 PM CST. The Tornado Watch does include Little Rock.
Additional areas could be included in a Tornado or Severe Thunderstorm Watch later this evening. If you live in or near the Tornado Watch, please keep a close eye on this evolving situation, have a couple reliable sources to receive weather information from, and have a plan in place in case a warning is issued for your area.
