It seems our Second Severe Season has arrived albeit a bit late. Normally the fall severe weather begins in Mid to late November in the southeast. November this year was quite with the exception of a potential severe weather event in the southeast that never materialized during the Nov. 11th thru 13th time frame. If you were around this past week you may recall the Storms and Tornadoes in the Southeast on December 10 2012. on with the show …
This coming bout of potential Severe weather will begin Late Saturday in the ARK-LA-MISS area shifting east with time into Alabama, Georgia and northern Florida. There remains uncertainty with the system as to timing and how strong storms may become due to how strong the upper level low pressure expected to develop in the northern tiers of this region becomes. The stronger the ULL, the more moisture it will pull north from the Gulf of Mexico into an already somewhat unstable air mass closer to the coast and extending northward. Regardless, am expecting some strong storms with isolated severe at this time throughout the region beginning today thru Monday again spreading west to east. Right now [5:05 AM EST 12/15/2012] confidence is somewhat LOW to the severe side based on how much cloud cover and rain occurs ahead of the frontal system in the warm sector.
Threats with this system will be in the form of Isolated strong to severe storms with the potential for a few Tornadoes with stronger storms possible. While the threat of tornadoes looks low at this time, a couple can’t be entirely ruled out due to increasing shear layer to layer which may became surface based over time supporting Bowing Line areas capable of Damaging Straight Line winds and Isolated Supercells which may spawn a Tornado. There is also a threat of Flash Flooding in areas with 1 to 2 inches of rain expected. As always .. not everyone will experience severe storms.
Today through Tomorrow morning the main threat will be the possibility of Damaging winds associated with strong thunderstorms that may develop generally in the afternoon and evening hours continuing through the overnight. … On Sunday the possibility of severe storms increase and continues into the overnight into Monday. On Sunday the Storm Prediction Center at this time [5:17 AM EST 12/15/2012] has an area highlighted for an elevated risk for strong to severe storms. We’ll see how this area looks later today for possible increase in severity or even a decrease. For now here is what they have for Sunday Morning through Monday Morning. [click image to embiggen]
