283 FXUS61 KALY 301044 AFDALY AREA FORECAST DISCUSSION National Weather Service Albany NY 644 AM EDT Sat Aug 30 2025 .SYNOPSIS... High pressure gradually building over the region will bring fair and pleasant weather through the Labor Day Holiday Weekend. Mainly dry weather continues on Tuesday and Wednesday before the next chance for a more widespread rainfall arrives Thursday and Friday. && .DISCUSSION... A vertically staked low pressure system, centered across southern Quebec this morning, will slowly drift eastward through the day. High pressure will then slowly build eastward from the Great Lakes. The day will start off mostly sunny, but will become partly to mostly cloudy for most as the day progresses as daytime heating combined with the cold pool aloft increases instability driven clouds. Despite these clouds, most areas will remain dry. The exception would be across the Adirondacks, closer to the upper low, where a few light showers or sprinkles could develop during the afternoon hours. Otherwise, it will be a seasonably cool day with highs in the lower 60s to lower 70s. There will also be a west to northwesterly breeze with gusts reaching 20-25 mph at times, especially from the Mohawk Valley into the Capital District and Berkshires. The high continues to build overhead tonight and remains directly overhead through Monday, Labor Day. A Rex Block even tries to develop by Monday with an upper high to our north and upper low just to our south. Dry weather is expected tonight through Monday under a mostly clear sky. Highs Sunday and Monday will reach the 70s to around 80, right around seasonable normals with lows each night in the 40s and 50s. As surface high pressure remains overhead Tuesday and Wednesday, the Rex Block looks to break down as the upper low to the south begins to drift northward over our region Tuesday then eastward on Wednesday. Daytime heating combined with the developing cold pool aloft will increase instability for additional clouds and the potential for some isolated rain showers on Tuesday, mainly across the higher elevations. Most areas become dry again by Wednesday. High temperatures both days will continue to run near to slightly above normal with values in the lower 70s to lower 80s. The next best widespread rainfall potential occurs later next week as a potent upper level low and surface cold front approach from the west. In addition, an upper level shortwave may round the base of the longwave trough and develop and track a low pressure system up or off the coast. How these features interact with each other and track will determine when and how much rainfall occurs. With uncertainty of track and timing, have maintained keeping PoPs in the chance range (35 to 50%) until confidence in these features increases. With increasingly dry weather, any rainfall from this system will be beneficial. High temperatures later next week will be in the 60s and 70s with Friday the cooler day of the two. && .AVIATION /12Z SATURDAY THROUGH WEDNESDAY/... Through 12Z Sunday, mainly VFR conditions are expected with patchy clouds with bases of 5000-7000 FT AGL late this morning through mid afternoon. The exception will be some patchy MVFR Cigs at KPSF through 13Z/Sat, and additional patchy fog/low clouds after 04Z/Sun with intermittent IFR/LIFR conditions possible at KGFL and KPSF. Winds will be southwest to west at 4-8 KT through mid morning, then west to northwest and increasing to 8-12 KT with some gusts up to 20-25 KT possible by late morning, especially at KALB and KPSF. West winds will decrease to 4-8 KT around and after sunset, and less than 4 KT after midnight. Outlook... Sunday to Wednesday Night: No Operational Impact. NO SIG WX. Thursday: Moderate Operational Impact. Chance of SHRA. && .ALY WATCHES/WARNINGS/ADVISORIES... CT...None. NY...None. MA...None. VT...None. && $$ SYNOPSIS...Rathbun DISCUSSION...Rathbun AVIATION...KL
