Area Forecast Discussion National Weather Service State College PA 359 PM EDT Sat Jun 1 2019 .SYNOPSIS... A strong frontal system will bring drier and much cooler weather to the region by Sunday night. Before then, look for a chance of showers and thunderstorms, mainly over northern Pennsylvania this evening before spreading south with the cold front on Sunday. The first half of the week will be dry and cool. Some of the colder locations across northern areas will have morning lows close to freezing Monday and Tuesday. The second half of the week will warm up with the chance for showers or thunderstorms returning. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... Radar shows a few showers and thunderstorms now developing just north of NY/PA border. Some of these storms will meander into PA. More organized areas of convection upstream to the NW. These fast moving storms will approach NW zones later this afternoon and evening. Storms will decrease late evening with a quiet overnight period, before cold front approaches NW zones a bit before sunrise, bringing an increase in showers. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH 6 PM SUNDAY/... Will be tracking a strong cold front tomorrow. Just ahead of the front look for showers and thunderstorms to develop and spread SE. SPC has eastern half of CWA in slight risk for severe storms with afternoon heating and shear associated with frontal boundary. Models are moving this front along quickly and it could clear the CWA by late in the day. && .LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/... *A shot of unseasonably cold and less humid air Monday and Tuesday. *Frost possible across north central PA early Tuesday morning. *Unsettled pattern returns Wed-Fri following welcomed 2-day stretch of mainly dry weather. The mid to long range period begins with the large upper level low making its way through the Great lakes and southern Canada. The operation models are in fair agreement on the placement of this low 00Z Monday. However the solutions begin to quickly diverge early this upcoming week. The timing of the trough seems to be the variance with the EC moving it slower and shallower. The biggest affect from this low will be the advection of cold air into the region Monday. 850mb temps will range from -2C in the Northwest to 2C in the southeast. Couple this with a dry air mass and little clouds and there will be a good chance for frost through the northwest with the best chance early Tuesday morning. Monday will be similar in temperature but the tight gradient from the trough will remain. That should allow for persistent northwesterly winds. So have kept frost out of the wx grids on Monday for now. So expect temperatures across the region to be 10 degrees below normal Monday and Tuesday. The positive of the dry cold air is that will be rain free Monday through Tuesday. That reprieve from precipitation will be short lived as a short wave trough will ripple through the area Wednesday. Temperatures rebound, along with increase in dewpoints. That trough will bring a chance of showers Wednesday. That trough will be the harbinger of what the latter half of the week will bring as showers and thunderstorms will be possible through the latter half of the week and possibly into the weekend. && .AVIATION /20Z SATURDAY THROUGH THURSDAY/... Mainly VFR except for patchy shower and thunderstorm activity closest to NY border. Watch for more organized convection approaching NW area VCNTY KBFD after 20Z continuing into the evening. More convection on Sunday as a strong frontal system moves w to e across the state during the day. .Outlook... Sun...Brief restrictions probable in showers/t-storms. Mon-Tue...No sig wx.
