548 FXUS61 KBGM 111808 AFDBGM Area Forecast Discussion National Weather Service Binghamton NY 208 PM EDT Mon Aug 11 2025 .SYNOPSIS... High pressure remains in control through tomorrow with temperatures remaining quite warm. Humidity levels remain comfortable tonight before starting to increase later tomorrow. A front moves in Wednesday with a widespread chance of showers and thunderstorms, especially in the afternoon, before drying back out later in the week. && .NEAR TERM /THROUGH TUESDAY NIGHT/... Dry and quiet conditions will continue across the area tonight through much of tomorrow as surface high pressure overhead slides off to the east and upper-level ridging remains in place. With the surface high off to the east tomorrow, there will be an increase in moisture advecting northward which is reflected by the dew points rising into and through the 60s. As a result it will feel more sticky tomorrow, especially later on in the day. A shower or thunderstorm popping up in one or two spots cannot be ruled out in the afternoon or evening over the high terrain with the influx of moisture combined with the heating of the day. Dew points were lowered a bit from NBM with its high bias as most guidance caps dew points in the lower and mid 60s tomorrow before increasing tomorrow night. As a result, apparent temperatures look to generally remain below heat advisory criteria in the valley locations of CNY. A few locations may still have heat indices touching the mid 90s, but this looks to be too brief and localized to warrant headlines at this time. Lows tonight will be in the 50s and 60s. Highs tomorrow generally range from the upper 80s to the low 90s. It will be noticeably milder tomorrow night with lows in the mid 60s to the lower 70s. && .SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/... Upper-level ridging breaks down Wednesday as a shortwave trough and surface cold front move into the region bringing our first widespread chance of showers and thunderstorms to the area in quite some time. While it won`t be quite as warm with the increase in clouds and scattered convection, with the cold front not passing through until later in the afternoon and evening high temperatures still reach the mid and upper 80s. MUCAPE values generally range from 1000-2000 J/kg Wednesday afternoon and evening, but shear looks pretty marginal, around 15-25 knots, although the NAM is little higher around the Finger Lakes and Lake Plain, closer to 30 knots. Mid-level lapse rates are pretty poor, so severe weather chances are low at this time. However, PWATs do rise between 1.50 and 2.00 inches, so locally heavy downpours seem to be the main concern at this time. Partly to mostly sunny skies are expected on Thursday. Depending on the speed of the cold front pushing off to our south and east, a small chance for a shower or thunderstorm may linger across the Catskills and NE PA. A wide range in temperatures is expected as high pressure and a cooler, drier air mass build in from the northwest with temperatures in the upper 70s and low 80s across CNY, while the Twin Tiers, southern Catskills and NE PA are in the low and mid 80s with some valley locations reaching the upper 80s. Comfortable Thursday night with lows mainly in the 50s. && .LONG TERM /FRIDAY THROUGH SUNDAY/... High pressure is expected to be in control for the end of the week with ridging building in aloft. Temperatures will gradually rise Friday into the weekend, returning to the upper 80s and low 90s by Saturday. A chance of showers and thunderstorms may return by Sunday as the next frontal boundary approaches. && .AVIATION /18Z MONDAY THROUGH SATURDAY/... High pressure will bring VFR conditions with mostly clear skies and light winds through the period. Outlook... Tuesday...VFR expected. Wednesday...Scattered showers and thunderstorms associated with a cold front can lead to occasional restrictions. Thursday through Saturday...Mainly VFR. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None. NY...Air Quality Alert until 11 PM EDT this evening for NYZ062. && $$ SYNOPSIS...AJG/DK NEAR TERM...DK SHORT TERM...DK LONG TERM...DK AVIATION...ES/MPK
