457 FXUS61 KALY 091843 AFDALY Area Forecast Discussion National Weather Service Albany NY 243 PM EDT Sun Aug 9 2026 .WHAT HAS CHANGED... Adjusted probability of precipitation to reflect current forecast timing and increasing confidence for chances of rain showers and isolated thunderstorms tomorrow afternoon and evening. Otherwise, no significant changes were made to the current forecast. && .KEY MESSAGES... 1) Scattered rain showers and isolated thunderstorms tomorrow afternoon and evening across eastern New York and western New England. A few storms could become severe tomorrow afternoon and early evening for locations south of I-90. && .DISCUSSION... KEY MESSAGE 1... After a breezy and comfortable summer day today, humid conditions return tomorrow morning across eastern New York and western New England as a warm front moves through. Additionally at the upper levels, a shortwave trough moves through helping contribute to a favorable environment for thunderstorms to develop tomorrow afternoon and evening across eastern New York and western New England. Latest high resolution forecast models are suggesting timing for thunderstorms and rain showers is between 1 PM and midnight tomorrow. The latest forecast supports thunderstorms to develop for locations south of the Mohawk Valley to the Greater Capital Region, including the eastern Catskills, Mid-Hudson Valley, Taconics, and Litchfield Hills, during the afternoon hours. With plenty of daytime heating, moisture from the associated warm front, and shortwave trough to move through, strong to severe thunderstorms could develop for those locations during the afternoon hours tomorrow. Taking a deeper dive into the environment, energy and instability needed for strong to severe storms is present on the latest high resolution forecast models. A Marginal Risk (level 1 of 5) for isolated severe thunderstorms tomorrow has been introduced for locations south of the I-90 corridor from the Storm Prediction Center. With latest forecast trends on the environment for tomorrow for those locations, this increases forecast confidence for isolated severe thunderstorms to occur tomorrow afternoon. The primary hazard is going to be strong to damaging wind gusts with severe thunderstorms. One thing to note, the ground continues to be saturated across these locations, so strong wind gusts over 50 mph may be all it takes to uproot trees and damage trees. Heavy downpours can also occur with thunderstorms tomorrow as enough moisture and energy above the surface is helping contribute to the potential of isolated instances of flash flooding from thunderstorms tomorrow afternoon and early evening. As the sun sets tomorrow evening, energy and instability decreases helping contribute to weaken the environment needed for strong storms south of the Greater Capital Region. For locations northward, we will need to continue to monitor trends as an isolated strong storm can develop during the overnight hours as a cold front starts to push eastward into eastern New York. A low pressure system over the Great Lakes region is currently supported to move north and east into Canada, but brings a cold front to move through eastern New York and western New England during the overnight hours Monday into early Tuesday morning. The cold front brings relief from the humidity and dry conditions are in store behind it for Tuesday. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... Through 18Z Monday... VFR conditions prevail across all terminals throughout this TAF period, with winds out of the west to northwest. KALB and KPSF are seeing some gusty winds, up to 15-20 kts, early this afternoon associated with a cold front passage. A few fair weather cumulus are also present across the region, which are expected to gradually clear into the evening. Calm winds and clear skies will dominate across all terminals throughout the overnight period. This could lead to some radiational mist/fog formation, particularly at KGFL and KPSF, which could cause brief vis and cig drops reflected in the TEMPO groups at those terminals. Mostly clear skies will continue into late morning and early afternoon on Monday, with southerly to southwesterly winds developing within the last several hours of the TAF period. KGFL and KALB will also begin to see cigs begin to drop during that period, though conditions are expected to remain VFR. Outlook... Monday Night: Moderate Operational Impact. Chance of SHRA...TSRA.
