.SYNOPSIS... Today will be mostly dry with a better chance of rain tonight into tomorrow as the western side of a coastal low pressure system impacts the area. Cooler and drier weather returns by the middle of next week.
&&
.NEAR TERM /THROUGH MONDAY/... 330 AM Update...
Rain is lingering east of I-81 early this morning and will slowly dissipate by mid to late morning. Water vapor imagery shows several upper level lows on the east coast, with one weakening in Western NY that is responsible for the rain, and a more robust low down off of the Carolina coasts. Deep convection near the center of the low means that this low will likely deepen over the next day or so as it slowly propagates up into the Mid Atlantic region. The upper level low over Western NY never completely dissipates and will help with creating a trough between it and the coastal low. Today is looking mostly dry as deeper moisture is still well south of the region and advection does not pick up till later today and overnight when 850 mb winds pick up out of the east at 40 to 50 knots.
This easterly flow tonight into tomorrow off the Atlantic will bring in another round of rain, with east facing slopes being favored. Eastern areas of the Catskills and Poconos may see a period of heavier rain tonight into tomorrow with an additional 1 to 2 inches. Across the Twin Tiers, the Wyoming Valley, and CNY, downslope winds may lead to some rain shadowing so QPF along and west of I-81 north of the Poconos may see less rain than modeled.

.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/... 340 AM Update...
With a western US trough digging in and a strengthening jet stream across the central US, the coastal low gets kicked out to sea Monday night into Tuesday with dry NW flow taking over. Trends have been towards the ridge in the central US to be a little farther east so a shortwave trough that was bringing a good shot of colder air is looking more likely to miss to the east.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/... 350 AM Update...
Despite not having as cold of an airmass move in, dry air, clear skies, and long nights will lead to good chances of another widespread frost and freeze Wednesday and Thursday night. The central US ridge will eventually build into the eastern US by next weekend with return flow helping to moderate the temperatures back towards seasonable averages.
&&
.AVIATION /12Z SUNDAY THROUGH THURSDAY/... With the rain out of the region, VFR conditions are expected until late today. Lower ceilings associated with a coastal system will move in from the south beginning around 21z at AVP and then spread northward to the Central NY terminals after 00z. MVFR to Fuel Alt restrictions are expected. Some guidance was hinting at IFR but similarly to last night, any IFR will be brief so conditions were capped at Fuel Alt for now. Rain showers move in after 00z and visibilities will be slightly reduced at times. Showers and restrictions will then continue through at least the end of the TAF period.
Winds will be west to northwesterly throughout this TAF period. Sustained speeds will be 5 to 10 kts with gusts of 15 to 20 kts. The gusts will subside at most Central NY terminals tonight but will remain at BGM and AVP.
Outlook...
Monday...On and off rounds of rain with associated restrictions.
Tuesday through Thursday...Mainly VFR.
