.SYNOPSIS... High pressure dominates and continues the dry weather pattern with above normal temperatures across the region through early next week. A passing front is likely to bring a batch of rain Tuesday into Wednesday.
&&
.NEAR TERM /THROUGH TONIGHT/...
High pressure continues, bringing dry conditions as well as above normal temperatures. The center of high pressure will slide southward a bit with a southwesterly return flow, allowing for warm air advection to bring well above normal high temperatures today, which will continue into the weekend and early next week.
Clear skies and calm winds overnight tonight will allow for valley fog to form as well.
&&
.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
The first weekend of October will feel more like summer, with zero chance of rain and plenty of sun as dry high pressure still dominates. Continued southwesterly return flow at the surface, and also ridging aloft, will continue to raise high temperatures well above normal. While not breaking daily records, temperatures could get within at least within shouting distance of them.
&&
.LONG TERM /MONDAY THROUGH THURSDAY/...
Yet another warm and dry day is anticipated Monday, but a well- advertised frontal system is forecast to bring welcome rain during the Tuesday-Wednesday time period.
Return flow on the back side of slowly departing high pressure will keep the heat pump going Monday, which will also remain dry with a mostly sunny sky. Meanwhile, models project a strong upper trough digging from Central to Eastern Canada, which will send a frontal system through our region sometime in the later Tuesday to Wednesday timeframe.
The latest run of the National Blend of Models indicates over 70 percent chance of receiving over a quarter inch of rainfall across the area as the cold front passes during the Tuesday to Wednesday timeframe. The biggest uncertainty lies with when it arrives and departs. Either way, what starts off as upper 70s-lower 80s Monday will knock down considerably behind the front by Wednesday to something closer to normal. Given the recent dry spell, this rain will generally be helpful, especially in terms of pausing fire weather concerns.
&&
.AVIATION /06Z FRIDAY THROUGH TUESDAY/... VFR conditions expected across the region through the TAF period.
Our normal fog hot spot, ELM, should remain fog free tonight as clouds streaming over head should limit cooling and somewhat strong winds from 950mb-900mb should help mix moisture out of the boundary layer. Confidence is pretty high in VFR conditions, but ELM does have some quirks where patchy ground fog will form quickly if winds dissipate for a short period while we have a clear patch of sky overhead. This could allow for few brief periods of ground fog a few feet off the ground, but thick fog is not expected and thus confidence was not high enough to include a TEMPO in the TAF.
Outlook...
Friday night through Monday...VFR with patchy valley fog and associated restrictions possible.
Tuesday...Potential for restrictions in rain and clouds as a cold front approaches the region.

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