Quick upper-air analysis at 500mb shows a subtle shortwave driving convection over Georgia, with a longer-wave trough stretching from the Great Lakes to Texas. A 592dm ridge centered over Florida is keeping us in the warmth to start the week. Working on *that* post now…
Subjective surface analysis depicts our last few hours in the warm sector before the cold front at the SC/NC border moves by this evening. Temperatures approaching 80° ahead of it, while temperatures are in the 50s behind it. Won’t rule out some showers and maybe a thunderstorm ahead of the front as it sinks southward, with more rain settling in this evening into the overnight.
01z surface analysis across the Southeast shows the coastal front maybe 20 miles offshore of the Lowcountry this evening. A wave of low pressure is, as expected, developing off the FL/GA coasts and will ride the boundary northeast, nudging some elevated instability into the area over the next few hours. Radar is beginning to show some heavier rain building into Beaufort and Jasper counties, and this is expected to translate northeast with time into #Charleston.
