Area forecast discussion, May 6, 2:10 PM CDT, 4 hours 2 minutes before
Area Forecast Discussion National Weather Service Paducah KY 210 PM CDT Thu May 6 2021 .SHORT TERM...(Tonight through Friday night) Issued at 200 PM CDT Thu May 6 2021 Approaching cold front now on doorstep of FA, setting off active convection, strong-severe, across FA along/ahead of its approach. There will continue to be a marginal to slight risk of severe as the front approaches, with low topped supercells possible. With freezing level near -8C and -20C level roughly 10K higher, large hail also possible along with damaging wind gusts. Should be short-lived during peak heating/tied to front. Afterward, drier dew points sweep in, with potentially some 30s dew points forecast thru tmrw. These will begin moderating again by tmrw night as a warm frontal boundary returns to the area, bringing the next chance of rain. .LONG TERM...(Saturday through Thursday) Issued at 200 PM CDT Thu May 6 2021 The wet weekend signal is still there, but storm total qpf amounts appear to be improving, as the heaviest qpf axis shifts north and west of the FA. Still, with the warm front's lift across the area Saturday, then warm sectoring Saturday night, ahead of the approaching cold front Sunday (passage Sunday night), anticipate gradual re-moistening/destabilizing environ with high pops returning, including thunder chances. By the end of the weekend, storm total average qpf in the 1 to 2 inch range seems likely. Behind the cold fropa, a cooler than climo norm airmass settles across the FA next week. 60s for highs and 40s for lows can be expected each day. While spotty rain chances cannot be completely ruled out any day, an early week drier, versus mid week wetter, approach appears the most likely scenario given the synoptic scale evolution from quasi zonal (early) to more amplified troffing (mid-late) week. && .AVIATION... Issued at 200 PM CDT Thu May 6 2021 Lower bases/cigs and potential thunderstorms with vsby restrictions are anticipated at terminals, at least in vicinity fashion if not categorical, thru late pm hours. A cold front's passage will then end restrictions associated with frontal convection, and improve skies overnight. Winds will shift to gusty northwest behind the front, then wane as higher pressure moves in/takes over, returning all Visual Flight Rules for the latter half of the flight forecast package. && .PAH WATCHES/WARNINGS/ADVISORIES... IL...None. MO...None. IN...None. KY...None. &&
