Area forecast discussion, Jun 3, 2:46 PM EDT, 4 hours 30 minutes before
Area Forecast Discussion National Weather Service State College PA 246 PM EDT Sat Jun 3 2023 .SYNOPSIS... Showers/storms will drop south of the area this evening as drier and cooler air is pushed in on good northerly flow. Seasonably cooler and drier air will follow in the wake of the front. The cooler conditions will be here for much of next week. Precipitation will be unlikely, too. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... SHRA/TSRA popping up right on schedule. Recent SWOMCD indicates no urgent concerns for widespread svr convection. An isolated cell or two may become severe due to high CAPE and steep mid level lapse rates. Deep convection at 18Z is generally along the ridges of the Alleghenies. This is likely the first volley of storms, as the meso models generate more convection over the east than the west later this aftn and evening, dropping into the south-central mtns. A little wary of following this too closely, as the cooler temps and lower clouds they have had for much of the day are currently a stabilizing influence. Areal coverage of the storms is not expected to be high/widespread enough to warrant 100 PoPs except in small areas if we see the whites of their eyes. The dry air continues to make it's way south this evening, and should eventually clear the SHRA/TSRA out to our S well before midnight. Some lower clouds will probably be trapped under the subsidence inversion over the southern Alleghenies overnight. So, we've included mentions of fog and higher clouds there. Clearing across the north and dewpoint drop will help mins reach the u40s in the nrn mtns, but the clouds in the SW will keep them in the m50s. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/... The upper low will wobble around New England, mainly offshore for the period, driving 8H temps down. Dry air mixes down and clears out the SW in the first half of the morning. The wind will back some to the N for the aftn, and this will help drop dewpoints even more. Even mixing up to 5-7kft and tons of sunshine on Sunday we'll struggle to get temps near 80F anywhere. The SE cities will get into the m70s, but that's not much below normals (2-4F below) for early June. Dry air and light wind will allow temps to drop into the 40s everywhere Sun night, except perhaps the urban areas of the SE. && .LONG TERM /MONDAY THROUGH FRIDAY/... Medium range guidance shows a deepening upper trough over the NE CONUS into next week, likely resulting in cooler than average temperatures for early June. The trough axis along with the bulk of rainfall looks likely to remain east of PA. Relatively cool temps aloft coupled with occasional shortwaves rotating southward across the area could support some showers and thunderstorms each afternoon, but models suggest that very little moisture will be in place and rainfall will be light. The upper level low begins to move east of the area on Friday, allowing for a gradual warming trend to begin and lower chances for rain. && .AVIATION /19Z SATURDAY THROUGH THURSDAY/... 18Z TAFS sent. Some adjustments to the AOO and JST for a thunderstorm. Westward moving cold front will result in a chance of shower or storm until sunset. Otherwise dry with mainly VFR conditions into Monday, as drier air builds southward. Some chance of MVFR CIGS at spots like JST later tonight. Expect winds to kick up after sunrise on Sunday, given the upper level trough swinging across the area. Outlook... Mon...Mainly VFR. Tue-Thu...Rain showers with possible t-storms in the afternoon. && .CTP WATCHES/WARNINGS/ADVISORIES... None. && SYNOPSIS...Dangelo NEAR TERM...Dangelo SHORT TERM...Dangelo LONG TERM...DeVoir/Bauco AVIATION...Martin
