Weather Aware Sunday-Repeated rainfall across east-central Alabama will lead to local flooding-Severe Weather window 7pm-Overnight (2am hinted by GRAF model)
The main impact will be the 1-2” and possibly more rainfall across east-central Alabama, especially parallel to the I-85 corridor. This will be starting around 9/8 CT in the morning through midnight central time. Repeated rainfall over the same areas or (training-we call it) will cause local street flooding. Severe weather set-up comes later potentially in the evening or after sunset…All depends on the warm front and the northern edge of this surface warm front…
We have to wait and see. We are in a Marginal Risk or 1 out of 5 for damaging winds and isolated tornadoes…Not a wide-scale event.
Breakdown: The entire event starts with the upper low when its position becomes off to the west…A surface low across Louisiana will need not be watched closely because this will set-up a typical low-level jet ahead of the surface low and then we need to watch how far the warm front lifts into the region.
By way of the low, it may get as close to central Alabama and Georgia after sunset… The good news will be the rain-cooled air and the lack of low-level surface instability. A lot of “what if’s”, so we need to stand by.
The wrap-around moisture for travelers Monday afternoon through Tuesday morning will bring snow flurries and possibly light snow accumulations for the higher terrain across northeast Alabama and northwest Georgia. A cold plunge follows with a wind chill and a preview of winter-like weather.
Late week: And yet again another cut-off low will bring a change for Friday but timing is fluid but hopefully out in time for next weekend and the Santa Clause Classic 10K at Callaway Gardens.
Greg Majewski will keep you all updated tonight on both shows, so stay with The First Alert Weather team tonight on News 3.
