Area forecast discussion, Jul 25, 2:22 PM EDT, 1 hour 29 minutes before
AREA FORECAST DISCUSSION National Weather Service Charleston WV 222 PM EDT Sun Jul 25 2021 .SYNOPSIS... Showers and thunderstorms increase into this evening, ahead of a cold front that crosses Monday. Drier air returns through Wednesday, with active weather returning for the end of the week. && .NEAR TERM /THROUGH MONDAY/... As of 200 PM Sunday... Convection ahead of the approaching weak surface front will gradually increase in coverage a bit through the remainder of the afternoon as some sunshine is being realized. Pops were lowered once again given past few runs of CAMs, capping most locales at high chance. Severe chances continue to look meager given lack of overall shear and upper level support. Activity will take awhile to fade early this evening, giving way to areas of low stratus and fog overnight as the surface front slowly sags southeast through the area. Upper level trof axis crosses during the predawn and early morning hours which should allow showers to reform in the vicinity of the frontal boundary along and south of I64. The front will take until the late afternoon Monday to exit southeastern portions of the forecast area as morning low stratus gives way to low based cumulus elsewhere. && .SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/... As of 220 PM Sunday... Monday evening starts off with a post-frontal situation where a weak cold front will be draped across our southern periphery until any lingering shower activity is gone by the overnight. This weak cold front will not lower temperatures at all with expected lows to be just around average and Tuesdays highs in the low 90's, moderately higher than the climatological norm. This will aid in some possible diurnal convection which will be sub-severe if any comes to fruition and should be very isolated in nature. High pressure aloft will support the suppression of most thunderstorm growth as well as provide fair weather outside the possibility of isolated shower activity during the afternoons through this period. Temperatures will continue to thrive in the low 90's with right around mid to upper 70's in the mountains. && .LONG TERM /THURSDAY THROUGH SUNDAY/... As of 1215 PM Sunday... High pressure aloft anticipated for Thursday although an upper low over Canada will push in a frontal band by midday creating the best chances for convection through this entire period. Models are in close agreement on this solution and have the feature affecting the area into Friday morning with a slow progression to the southeast. Steering flow during passage seems moderate to strong therefore moved the feature out of the area slightly quicker than what guidance had by trimming off POPs sooner. Thinking any activity will be in the form of some lingering showers for the overnight with very low chances for anywhere else other than the southern most portions of the CWA through Friday morning. This is mainly due to high pressure both sfc and aloft quickly taking over. Ensembles have PWATs anomalously high during this features passage which could promote excessive rainfall during the daytime, consequently causing minor flooding issues under strong thunderstorms. By Friday, high pressure at the sfc and aloft settles in for a nice break in Saturday. Long range models keep Saturday dry, but with lowering heights some potential diurnal pop ups are still on the table. Long ranges models then have a few disturbances traversing near the area over the rest of the weekend raising chances for showers and storms, but they are in disagreement on timing and location, therefore accepted central guidance which equated to chance POPs/storms the rest of the period. Did cap storm probability to just slight chances since models were in disagreement at this point. After Thursday, temperatures drop back down to just below seasonable with cooler than average nights expected. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... As of 205 PM Sunday... SHRA/TSRA will gradually increase in coverage through 00Z ahead of an approaching cold front, though still below thresholds for anything other than a VCTS mention in the TAFs. Activity will slowly fade this evening, with areas of low stratus and dense fog developing. Some uncertainty as to the extent and magnitude of any resulting restrictions exists, however. Showers may redevelop along the front toward morning, possibly affecting KCRW and especially KBKW. LIFR/IFR Fog/low stratus will give way to primarily MVFR low based cumulus by late morning. Weak southwest surface flow tonight and Monday morning veers to the west and northwest behind the front in the afternoon. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z MONDAY... FORECAST CONFIDENCE: Medium, except low overnight. ALTERNATE SCENARIOS: Brief IFR VSBY in any robust shower/storm through 00Z. Development and extent of fog and/or stratus late late tonight into Monday morning may vary from forecast.
