016 FXUS61 KALY 041815 AFDALY AREA FORECAST DISCUSSION National Weather Service Albany NY 215 PM EDT Fri Jul 4 2025 .SYNOPSIS... High pressure over the region tonight will result in dry and cool conditions. Temperatures will warm back to normal levels on Saturday, as high pressure shifts east off the coast. Increasing heat and humidity is then expected for Sunday and Monday. Chances for showers and thunderstorms will also increase on Monday, as a cold front starts to slowly move south across the area. && .NEAR TERM /THROUGH SATURDAY/... After stellar Independence Day weather, tonight will be clear and cool with high pressure directly over the area into Sat morning. There could be some patchy fog in typical sheltered areas, but otherwise clear skies and light winds will lead to good radiational cooling conditions with lows mainly in the lower to mid 50s. As high pressure shifts east off the coast on Sat, a southwest flow will develop around the periphery of the departing high. This will result in temperatures warming considerably during the afternoon after a cool start to the day. Highs should reach the lower/mid 80s in most valley locations. Subsidence will still prevail, so mostly sunny and dry conditions expected to persist. && .SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/... Key Messages: - Hot and humid conditions Sunday into Monday. Heat Advisories may be needed in some areas. - Showers and thunderstorms develop on Monday associated with a cold front passage. Discussion: Tranquil conditions, but with milder temperatures(lower/mid 60s) in store for Sat night with a south-southwest flow persisting. More significant heat and humidity return on Sun, with warming aloft well ahead of a cold front slowly sagging south across SE Canada. 850 temperature anomalies are forecast to increase to +1 to +2 STDEV. Highs expected to reach the lower 90s in most lower elevations with dewpoints increasing to around 65-70F. This results in maximum feels- like temperatures in the mid to upper 90s, so Heat Advisories would eventually likely be needed in some areas. The cold front should remain far enough north for dry conditions to persist through Sun. The cold front`s progress should slow Sun night as weak waves of low pressure develop along it. So again much of the area looks to avoid any convection except for maybe far northern reaches of the W. Adirondacks. Sun night will be mild and humid with lows only in the mid 60s to lower 70s. Mon will be another very warm and humid day, with similar high temperatures(lower 90s in valleys) and feels-like temperatures in the mid/upper 90s. The cold front is expected to slowly push southward into the area, especially during the afternoon/evening hours. Given the warm/humid air mass, some stronger thunderstorms may occur with deep layer shear ~25-30 kt resulting in potential for organized storms. Also locally heavy rain is possible as PWAT anomalies rise to +1 to +2 STDEV. Low confidence in timing/coverage for now, but will continue to monitor trends. && .LONG TERM /MONDAY NIGHT THROUGH THURSDAY/... Key Message: - Near normal temperatures with somewhat unsettled conditions, especially later in the week. Discussion: The aforementioned cold front will continue to push southward through the area Mon night, with chances for showers and some T- storms persisting. Potential for T-storms will diminish overnight as instability wanes. The front may slow or even stall on Tue across the southern part of the area, so chances for showers/T-storms will linger especially south/east of Albany. It will remain rather humid, but high temperatures(mid/upper 80s valleys) should be slightly cooler due to more cloud cover. The front should eventually shift south of the area by midweek, but may still be in close enough proximity to result in widely scattered diurnally driven convection on Wed. Temperatures still look to be slightly above normal with moderate humidity levels. A better chance of more widespread unsettled weather is expected Thu into Fri, as a deepening upper level trough and potential surface cyclone move across the area. NBM showing chance PoPs through the period, which seem reasonable for now until details come into better focus. && .AVIATION /18Z FRIDAY THROUGH WEDNESDAY/... Through 18z Saturday...VFR conditions continue through at least the first half of tonight with just a few mid-level clouds around. With high pressure moving overhead tonight, some patchy fog is expected at GFL/PSF and has been added with tempo groups. IFR or lower vsbys expected with any fog. Fog dissipates shortly after sunrise with a return to VFR conditions with FEW to SCT high clouds around through 18z Saturday. Winds will be at 5-10 kt from the NW through this evening with some gusts of 15-20 kt, before diminishing to 4-8 kt from the west this evening. Winds become calm by midnight lasting through mid- morning tomorrow before increasing back to 4-8 kt from the S/SE. Outlook... Saturday Night: No Operational Impact. NO SIG WX. Sunday: No Operational Impact. NO SIG WX. Sunday Night: No Operational Impact. NO SIG WX. Monday: Moderate Operational Impact. Chance of SHRA...TSRA. Monday Night: Low Operational Impact.
