366 FXUS61 KALY 152345 AFDALY Area Forecast Discussion National Weather Service Albany NY 745 PM EDT Tue Sep 15 2026 .WHAT HAS CHANGED... Capped PoPs at likely values for areas west of Albany on Thursday, as it does not look like a washout at this time with scattered/numerous coverage of showers. Also lowered NBM dewpoints this afternoon through Wednesday. && .KEY MESSAGES... 1) Temperatures moderate back to above normal levels for Wednesday through Thursday, along with increasing humidity and chances for showers and a few thunderstorms. 2) Dry and cool weather returns Friday into Saturday, before unsettled conditions possibly develop late Saturday into Sunday. && .DISCUSSION... KEY MESSAGE 1... High pressure shifts east off the New England coast tonight, with warmer air aloft moving in from the west. So temperatures will be not as cold as last night. Also temperatures will warm back above normal on Wed, with a mix clouds and some sunshine. Highs expected to reach the upper 70s to around 80F in most valleys. Other than a few showers across the Adirondacks tonight it should be mainly dry. A weakening cold front will approach from the NW on Wed, but limited forcing/moisture will likely only result in a few sprinkles in some spots. The front washes out and becomes diffuse over the area Wed night, with dry, mild and slightly humid conditions. The next appreciable chance of showers arrives on Thu, as a weak wave of low pressure is expected to track east along the old/diffuse front. Main time frame looks to be late Thu A.M. into Thu P.M. Most numerous showers look to move across areas from around Albany north/west. Will only mention a slight chance of thunder west of Albany, as despite increasing moisture (PWAT anomalies of +1 to +3 STDEV) limited instability of < 500 J/Kg SBCAPE is forecast. Scattered showers may linger into Thu evening from around ALB south/east, then drying expected Thu night with continued mild temperatures. KEY MESSAGE 2... Upper level troughing developing across SE Canada will send a cold front southward across our region Thu night, resulting in a cooler and drier air mass filtering in on Fri. Dry/cool conditions should persist into Sat, as high pressure tracks eastward across southern Quebec. Temperatures expected to be below normal Fri night and Sat. The next chance of showers looks to arrive Sat night into Sun, as a wave of low pressure and frontal system approach from the west. While at least some measurable rainfall appears likely across much of the area during this time, there is low confidence in areal coverage/duration of showers and QPF amounts. && .AVIATION /00Z WEDNESDAY THROUGH SUNDAY/... VFR conditions continue for KPOU and KALB through the TAF period. For KGFL and KPSF, low stratus clouds could develop between 12z and 15z and bring MVFR ceilings through 18z before VFR ceilings return. Confidence is low on the potential rain shower activity at KGFL between 8z and 12z with a weather system moving through to our north, so included the mention of low chances in a PROB30 group for light rain with VFR visibilities and ceilings. Winds continue to be light and variable through the TAF period except at KALB where southerly light winds continue to range between 3 and 8 knots through the TAF period. Outlook... Wednesday Night: Moderate Operational Impact. Chance of SHRA. Thursday: High Operational Impact. Likely SHRA. Thursday Night: Moderate Operational Impact. Chance of SHRA. Friday: No Operational Impact. NO SIG WX. Friday Night: No Operational Impact. NO SIG WX. Saturday: No Operational Impact. NO SIG WX. Saturday Night: High Operational Impact. Likely SHRA.
