313 FXUS61 KALY 261036 AFDALY Area Forecast Discussion National Weather Service Albany NY 636 AM EDT Sun Apr 26 2026 .WHAT HAS CHANGED... Steady light rain will be winding down over the next few hours. Adjusted POPs based on latest radar trends to show precip ending towards daybreak across southeastern areas. With high pressure moving overhead, adjusted min temps down slightly for tonight and slightly higher for Monday, based on expected full sunshine. With drier air mass moving into the region, leaned towards the lowered end of the blended guidance for dewpoints on Monday. Adjusted winds slightly higher for Tuesday and dewpoints lower during peak mixing on Tuesday afternoon as well. && .KEY MESSAGES... 1) Behind a departing storm system, drier air will begin returning to the region today, with much lower humidity levels by early in the upcoming week. Depending on fuels, enhanced fire weather conditions could be a localized concern for Monday and Tuesday. 2) Unsettled weather and cooler than normal temperatures look to return for the middle to latter portions of the upcoming week, but impacts look minor at this time. && .DISCUSSION... KEY MESSAGE 1... Steady light rainfall, currently ongoing for areas south of the Mohawk Valley and I-90, will be exiting the region from west to the east early this morning. All areas should be done with precipitation around daybreak, although some low clouds and fog may linger into part of the morning hours. A light northerly flow should allow for gradually more drier air to work its way into the region for later today, although noticeably more drier air won't arrive until Monday. High pressure will be overhead for Monday, allowing for plenty of subsidence. With full sunshine expected, it will be much drier, with RH values as low as 25 to 30 percent on Monday afternoon. Mixing will be limited due to the high pressure in place, so winds will be fairly light. Still, with plenty of sunshine expected, have gone with temps slightly above the NBM for Monday, with highs in valley areas well into the 60s to near 70. Upper ridge axis will still be overhead on Tuesday morning, but it will be shifting eastward by later in the day as the next system starts to approach. With an increasing pressure gradient developing, southeast winds will be stronger on Tuesday, with some gusts reaching 20-25 mph during the afternoon hours. Although there will be more clouds around, RH values will still be as low as 30 percent during the afternoon hours. Daytime temps will still be rather mild, with values well into the 60s once again. With the return of drier air, fine fuels will likely be drying out rather quickly early next week during daytime mixing with the abundant sunshine. Although these RH values are fairly seasonable considering it is still technically pre-greenup, we will need to coordinate with state fire weather partners to get an update on fuel status. Fine fuels have a tendency to dry out very quickly, so despite recent rainfall (up to an inch across southern areas this weekend), fuels could potentially be ready to go. While winds will be fairly light on Monday, they will be somewhat breezy on Tuesday due to the increasing gradient. Fire Weather partners may be open to Special Weather Statements early next week, although current wind gust forecasts would suggest that widespread Red Flag conditions probably won't be reached. Based on the latest local fire weather operating plan, the combination of easily dried out fine fuels and seasonably low RH values within daytime mixing on sunny days will likely require fire weather coordination for Special Weather Statements and/or Red Flag Warnings until greenup occurs. KEY MESSAGE 2... There is some potential for Fire Weather concerns to be temporarily alleviated due to some potential for rain showers will a storm system for Wednesday into early Thursday. As a frontal boundary approaches, a band of showers looks likely for late Wednesday into early Wednesday. At this point, showers look light enough to avoid any flooding concerns. Behind this frontal boundary, it appears to remain unsettled for the rest of the week and towards next weekend. Upper level trough will be remaining overhead as a cutoff low remains over or near the region, keeping plenty of clouds and some additional showers around. With the trough in place, temps look to be below normal for late in the week, with daytime temps only in the 40s and 50s and overnight lows in the 30s. While the trough may limit fire weather concerns, the cooler weather could bring another spring concern if enough clearing occurs: Frost. The Frost-Freeze program begins May 1st for the Hudson Valley, southern Taconics and northwestern Connecticut. With overnight lows potentially in the mid to upper 30s for these areas late in the week, will need to watch for the potential to issue the first Frost Advisory of the season for the end of the week. && .AVIATION /12Z SUNDAY THROUGH THURSDAY/... All rain has ended across the region but some lingering low stratus and fog is still impacting the TAF sites, especially KGFL and KALB, with IFR/LIFR conditions. This may continue for the next hour or two, but drier air working its way into the area from the north should allow for VFR conditions to return towards the mid-morning hours. For the rest of the day, there will be just some passing sct lower clouds and some cirrus, and even these clouds will depart for tonight, with clear skies expected for tonight for all sites, as high pressure moves towards the area. With much drier air moving in, no fog or low clouds are expected to form for tonight. Light northerly winds will be around 5 kts for today. These winds will go back to being calm for tonight.
