.SYNOPSIS... Rain will move back into the area tonight into Monday as the western side of a coastal low pressure system impacts our area. Conditions will dry out by Tuesday and remain mainly dry for most of the week. Cooler weather will arrive on Wednesday and Thursday, before temperatures warm up by the upcoming weekend.
&&
.NEAR TERM /THROUGH MONDAY NIGHT/... 215 PM Update:
As expected, conditions have been mainly dry this afternoon as we are experiencing a lull between rounds of rainfall. There are a few light showers/sprinkles pivoting in from the southeast moving across parts of Northeast PA/Twin Tiers, but these are very light and may not even be reaching the ground in some locations due to drier air in place. Most areas west of I-81 have been mostly sunny, with more cloud cover east of I-81 due to the easterly flow off of the Atlantic.
This easterly flow tonight into Monday off of the Atlantic will bring in another round of rain. Due to this easterly flow, east facing slopes will see some local enhancement of rainfall, with some rain shadowing on the west facing slopes. The majority of the rainfall will occur after midnight tonight and through Monday morning, before the steady rainfall gradually tapers off to showers Monday afternoon and evening. Highs on Monday are expected to be in the 50s for most of the area due to the rain- cooled air and extensive cloud cover. Then lows in the 40s are expected Monday night.
&&
.SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/... 215 PM Update:
High pressure will approach the region on Tuesday, which will bring a return to dry weather and partly to mostly sunny skies. With a tight pressure gradient between the departing coastal storm and the approaching high pressure system, winds may still be somewhat gusty on Tuesday. Highs are expected to be in the 60s. Then dry and mostly clear skies are expected Tuesday night with lows in the mid 30s to mid 40s.
A northwest flow regime will set up Wednesday through at least Thursday, which will advect in a cool airmass. Highs on Wednesday will likely only be in the upper 40s to upper 50s despite mostly sunny skies. Then a cool night will be in store Wednesday night with lows in the upper 20s to upper 30s.
&&
.LONG TERM /THURSDAY THROUGH SUNDAY/... 215 PM Update:
The cool airmass will remain in place on Thursday with highs only topping out in the upper 40s to mid 50s despite another mostly sunny day. Then with light winds and mostly clear skies, lows Thursday night will likely drop down to at least the mid 20s to mid 30s.
The central US ridge will eventually build into the eastern US by next weekend. This will allow for a gradual moderation in temperatures starting on Friday and especially for Saturday and Sunday. The next more widespread chance of rain likely wouldn`t occur until at least Sunday, or possibly Sunday night into Monday with an approaching frontal system.
&&
.AVIATION /20Z SUNDAY THROUGH FRIDAY/... Low pressure will move slowly northward along the Eastern seaboard over the next 24 hours. Expecting a lowering of ceilings and increasing showers from SE-NW across the region beginning early this evening and continuing into the overnight hours. Generally speaking we`ll see mainly MVFR restrictions with IFR late tonight and Monday for AVP-BGM and ELM with VFR- MVFR at ITH-SYR and RME. Confidence in timing of the showers and restrictions is very low as guidance suggests multiple bands of developing rain which may start and stop allowing for rapid category fluctuations.
Prevailing winds will remain northeasterly at 8-15 gusting 20 kts through the period.
Outlook...
Tuesday through Friday...Mainly VFR. Chance of valley fog each morning.

.BGM WATCHES/WARNINGS/ADVISORIES... PA...None. NY...None.
