358 FXUS61 KBGM 190645 AFDBGM Area Forecast Discussion National Weather Service Binghamton NY 145 AM EST Wed Nov 19 2025 .SYNOPSIS... Low pressure passing by to the south will bring some light rain and high elevation snow to NE PA early this morning. High pressure building in later in the day will lead to quiet conditions through Thursday, then our next chance of predominately rain showers returns Friday into Friday night. && .NEAR TERM /THROUGH THURSDAY/... A quiet but chilly start to the day across CNY under clear to partly skies. Farther to the south across NE PA, it will be a bit trickier through 12Z as a quick-moving and weak area of low pressure currently over northern West Virginia slides by to our south and east. The northern edge of the precipitation with this feature will bring a light rain/snow mix to the area, with light snow reserved for the higher terrain. Temperatures around the I-81 and I-84 corridors and the Poconos are currently running a few degrees warmer than NBM, so the NBM90th percentile was blended in over the next several hours in this area. With dew points well down into the 20s, precipitation initially showing up on radar will be evaporating and this evaporational cooling will help lower temps. Wet bulb temperatures in the Wyoming Valley are expected to be in the mid 30s, allowing for much of the precipitation that does reach the ground to be in the form of rain, while the surrounding higher terrain is expected to have wet bulb temperatures at or just below freezing, especially in the Poconos and higher terrain of southern and eastern Luzerne County. This will allow for snow or a rain/snow mix in this area. Snowfall amounts in the high terrain will be less than an inch. As this system departs, high pressure will build in for the rest of the day. This surface high will move overhead tonight and gradually move east Thursday. Skies are expected to be partly to mostly sunny by this afternoon and a mix of sun and clouds is featured Thursday. Highs this afternoon range from upper 30s to the mid 40s while lows tonight will be mainly in the 20s. With the surface high to our east Thursday, the flow will become more southwesterly and while much of the area is expected to be in the low to mid 40s, many of the valley areas along the Southern Tier and into NE PA are expected to reach the upper 40s and perhaps near 50 degrees. && .SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/... A couple of features will be monitored Thursday night through early Saturday. An upper trough moving over the northern Great Lakes Thursday night is expected to pass by to our north Friday but the surface cold front with this feature may bring a few showers Friday into Friday night. Farther to the south and west, a shortwave is expected to eject out over the central and southern Plains with a developing surface low. As these features slide east and tap into some Gulf moisture, rain showers are expected to reach the mid- Atlantic region late week. There is some uncertainty as to how far north this moisture spreads as some deterministic and ensemble guidance has the bulk of this precipitation passing by to the south and possibly clipping NE PA, while other solutions spread moisture all the way up into the Twin Tiers and CNY through Friday night/early Saturday AM. Friday is expected to be a milder day with highs in the upper 40s to the low and even mid 50s in some places, which would keep precipitation in the area during the day Friday predominately rain. West to northwesterly flow Saturday cools temperatures back down mainly into the 40s. && .LONG TERM /SATURDAY NIGHT THROUGH TUESDAY/... While surface high pressure looks to build in for the second half of the weekend, there are a few short waves that look to move through the region embedded in predominately zonal flow aloft into early next week. This will keep at least a low chance of precipitation around through Tuesday. With daytime highs Sunday through Tuesday projected to be in the mid 40s to around 50 degrees (even some lower 50s possible in valley locations Monday), any isolated to scattered showers during the daytime would be rain, while a rain/snow mix is possible at night. && .AVIATION /06Z WEDNESDAY THROUGH SUNDAY/... VFR conditions are expected for the CNY terminals throughout the TAF period. Forecasted conditions at AVP have improved as dry air currently over the area combined with warmer temps and precipitation tracking more south than originally thought should keep conditions mostly VFR through the night. There will be a chance for a few periods of MVFR conditions at AVP between 09z and 11z as snow may mix in with the expected light rain showers. Prevailing MVFR clouds should remain until 15z with some drizzle possibly sticking around into the morning hours. VFR will prevail for the rest of the TAF period. Outlook... Wednesday night through Thursday...Mainly VFR. Thursday night through Sunday...Off and on periods of rain during the day and snow/wintry mix overnight with associated restrictions. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None.
