Skies are clearing out across much of the southeast as the air sinks with the upper trough that has ejected out. Some cloud cover and flurries are still noted over portions of central and south Georgia this morning. Sleet and Flurries have been reported as far south as Tampa, Florida so far today. That is pretty amazing. More unsettled weather will affect the region by mid week. We will get into that later.
Light snow in Childersburg, AL on Saturday 3/2/12
Periods of light snow fell through the day across much of Central Alabama and we had a chance to take a little bit of video on yesterday. This was a major difference compared to this time last year when much of the eastern half of the country was dealing with a massive tornado outbreak. Huntsville dealt with two strong tornadoes last year on the very day.
As you can see on our regional radar, snow is falling across several areas of the deep south this morning thanks to an upper level low pressure system centered fairly close to Asheville, North Carolina this morning. Portions of Tennessee have seen a few inches of snow in the Cumberland plateau between Nashville and Chattanooga. This snow will continue through much of the day as upper level energy moves toward the east.
On a more local level for us here at LSN, snow is falling deep into Central Alabama. Heavier radar returns are showing up in Jefferson County near West Jefferson and McCalla. The snow will continue off an on here today as well. Heavier bursts are possible if we get sunshine in a few hours as some snow “showers” or “squalls” could be more convective. We have taken a little video here from our base location this morning and will post up some of it in just a few hours. Hope everyone has a great Saturday and enjoy some of the non-nuisance snowfall!
A winter weather advisory has been placed for Jackson and Dekalb counties of northeast Alabama through noon on Saturday as decent snowfall is dropping south and eastward out of Tennessee and Kentucky. We actually expect a good chunk of north and central Alabama to see snowfall from this system, but most of the potential for accumulations of near 1” will be over the mountain terrain of northeast Alabama. We will monitor the progression of the snowfall and keep you updated if things change over the next several hours.
Thursday brings about another round of severe weather for the Deep South including severe storms with tornadoes and flooding rains. Live Storms Network Members Jason Brand and Brantley French are going to be out live tracking what unfolds through the afternoon. There seems to be a fairly well defined spatial area which has the best: daytime temp, dewpoint temp, instability 750+ with CAPE lobe rotating along the coast, SRH 500+, with an additional cap in place. Models clearly show a large warm sector developing and while storms throughout the day might be elevated later on some will take on rotating/sustained updrafts. We will be in this favorable area to see what unfolds. For the live stream looking out the truck choose Brantley French. For the Camera showing what we do inside the truck chasing click Jason Brand. We wanted to try out this interactive experience with you so while you are there it takes two seconds to join the chat chase room and chat with us! We all really appreciate the support and the community grows by you sharing with your friends the streams also. We got some more maps and some discussion for you so let’s get to it…
Above is the SPC Day 1 Outlook And Below is the SPC Day 1 Tornado Outlook
SEVERE STORMS WILL CONTINUE THROUGH THURSDAY EVENING AS A POTENT DISTURBANCE SWINGS ACROSS THE REGION INTO A SHEARED AND MODERATELY UNSTABLE AIR MASS. THE MOST INTENSE STORMS CAPABLE OF DAMAGING WIND GUSTS TO AT LEAST 60 MPH AND LARGE HAIL ARE MOST LIKELY ALONG AND SOUTH OF THE HIGHWAY 84 CORRIDOR WHERE INSTABILITY SHOULD BE HIGHEST. A FEW TORNADOES WILL BE POSSIBLE.
IN ADDITION…WIDESPREAD HEAVY RAINFALL IS EXPECTED WITH THIS EVENT…AND EXTENDING LATE THURSDAY INTO FRIDAY AS A FRONTAL BOUNDARY BRIEFLY STALLS IN THE VICINITY. PRECIPITATION TOTALS WILL LIKELY RANGE BETWEEN THREE AND FOUR INCHES BY LATE FRIDAY. GIVEN THE SATURATED STATE OF THE GROUND EXPECTED RAINFALL TOTALS AND RAINFALL RATES WILL LIKELY BE HIGH ENOUGH TO RESULT IN FLASH FLOODING IN AT LEAST A FEW LOCATIONS. SMALL CREEKS…STREAMS AND LOW LYING AREAS CAN ALSO EXPECT RISES IN WATER LEVELS.
ABOVE IS AN ANIMATION OF THE EVENT THAT SEEMS TO BEST FIT THE CURRENT SETUP AND EVOLUTION OF THE SYSTEM. YOU CAN COUNT ON THE LIVE STORMS NETWORK IN CONJUNCTION WITH LIVE STORMS MEDIA AND OTHER TEAM MEMBERS PROVIDING SUPPORT THROUGH THE WHOLE EVENT SO THANK YOU TO EVERYONE DOING THAT! SEE YOU ON THE LIVE STORM STREAM!!!
