Area forecast discussion, May 3, 5:06 PM EDT, 1 hour 17 minutes before
Area Forecast Discussion National Weather Service State College PA 506 PM EDT Fri May 3 2019 .SYNOPSIS... A cold front will push across the region late tonight, but will become stationary just to our south. A wave of low pressure will push east along the old front Saturday night. Drier and slightly cooler weather is expected for late Sunday through Tuesday as high pressure settles in. && .NEAR TERM /UNTIL 2 AM SATURDAY MORNING/... SVR watch 125 issued for the srn tier of counties west of the low clouds/stable layer over the eastern counties. The showers and storms across the north right now do not have quite the CAPE but a good amount of effective shear. The storms over the north are barely making ltg, but are training over the srn part of Tioga Co. Thus, we will need to keep a keen eye on all the developing storms this evening. Heavy rain is possible out of these storms as PWATs are over an inch everywhere and over 1.5 inches in the srn tier. WPC MRGL risk for flooding lines up nicely with the current and then expected storms. Things are growing well, now, and should be able to soak up some water. Still, 1hr FFG is near an inch in the Laurels and the NErn mtns, too. Most locations are >=1.5 inches. Cluster of storms associated with a strong vort max over wrn WV will continue to slide to the east and hit the good CAPE over our srn counties. The heaviest rain is concentrated over the SC counties for the 8PM- 1AM time frame. Don't have enough confidence in the threat for widespread flooding to post a FF watch at this point. && .SHORT TERM /2 AM SATURDAY MORNING THROUGH 6 PM SATURDAY/... The storms will slide eastward as the short wave goes with the flow tonight. It will get pretty murky and foggy tonight over much of the area. Low clouds should keep worry for a dense fog advy away from most of the area, but those ridge tops could be pea soup. The fog and low clouds linger through the morning in most places. Only the SE looks like it will have any kind of improvement by early afternoon thanks to a developing, but light, downslope NW wind. && .LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/... Central PA has been experiencing a stretch of unsettled weather recently, and next week looks no different. A wave of low pressure will lift out of the Tennessee Valley to a position near the Delmarva Peninsula by Sunday morning. This will bring a period of steady rain across south-central PA Saturday night into early Sunday. Slowly improving conditions are expected Sunday, as low pressure pulls off the East Coast. Monday should be a mainly dry day, between weather systems. On Tuesday, a weakening cold front will slip southeastward from the Great Lakes into the area late in the day, accompanied by scattered showers and thunderstorms. This front will stall just south of the region on Wednesday, before returning north as a warm front on Thursday. The week looks like it will end on an unsettled note, as waves of low pressure ride along a frontal boundary that is stalled in the vicinity of the Mid-Atlantic states. && .AVIATION /21Z FRIDAY THROUGH WEDNESDAY/... Updated the TAFS late this aft. Areas to the east not real warm, so threat of showers and storms lower. I did leave mention of storms in across the southeast at sites like MDT and LNS. Shower east of UNV died, so cut back on activity for UNV and AOO. Earlier discussion below. Improvement will only last a little longer in the cloudy/cool eastern terminals as SHRA/TSRA are expected to arrive in the next 5-6hrs. Gusty wind is possible in the storms, but MDT/LNS might still be too stable for much of a worry for severe wind gusts. Biggest story will be the lowering cigs and visbys overnight. After the rain moves to the east, the wind will go calm for the most part. Expect almost all terminals to go to IFR and at least half to go to LIFR conditions. Patchy drizzle is also possible. Only a slow improvement is expected Sat. The SErn terminals should break out first as a NW wind starts up. .Outlook... Sat night...Rain spreading SW to NE Sat night with MVFR to IFR. Sun...Rain/restrictions with drying trend into Sunday night. Mon-Tue...Mainly VFR. Tues PM-Wed...Mainly VFR. Showers poss nrn half. && .CTP WATCHES/WARNINGS/ADVISORIES...
