887 FXUS62 KCHS 230535 AFDCHS Area Forecast Discussion National Weather Service Charleston SC 1235 AM EST Sat Nov 23 2024 .SYNOPSIS... Canadian high pressure will remain the primary feature through early next week. A cold front could approach the area towards the middle of next week. && .NEAR TERM /UNTIL 6 AM THIS MORNING/... Early morning update: No major changes were made in the forecast. Winds have now decoupled over the region and allowing for some decent radiational cooling to take place. Current observations showing temperatures have cooled into the upper 30s/lower 40s across the interior with the coldest temperatures located over Berkeley County away from the Santee-Cooper lakes. Would not be surprised to see a few spots in the normally colder areas make a run for the freezing mark by daybreak, but any such conditions should be fairly localized. The current Frost Advisory area looks on track, although there are signals that an expansion could be needed into parts of Evans and Tattnall Counties. Another chilly night will occur as high pressure featuring a slightly modified cP airmass dominates the region. The 1022 hPa high is currently centered over northern Missouri/southern Iowa with an enhance pressure gradient in place across the Carolinas and Georgia between it and low pressure emerging off the Mid- Atlantic coast. Guidance is in pretty good agreement in showing the pressure gradient relaxing quite a bit after midnight as the high propagates into the lower Mississippi Valley and the low pushes farther offshore. This should allow the boundary layer to at least partially, if not completely, decouple away from the coast early Saturday morning under clear skies. With lows expected to drop into the mid 30s well inland, conditions look to become increasingly favorable for the formation of scattered (areas of) frost.
