183 FXUS61 KBTV 140452 AFDBTV Area Forecast Discussion National Weather Service Burlington VT 1252 AM EDT Thu Aug 14 2025 .SYNOPSIS... With the prolonged period of hot weather now in the rear-view mirror, a return to more season weather is expected through the weekend before a more significant cooldown impacts the region next week. A cold front on Sunday could bring some showers and thunderstorms to the region but overall dryness is expected through the next 7 days. && .NEAR TERM /THROUGH TONIGHT/... As of 1252 AM EDT Thursday...A few remaining showers continue across northern New York early this morning ahead of a stalled frontal boundary. We have seen a few flashes and cloud to ground strikes over the past few hours but the remaining instability appears to be elevated. Other than some beneficial rainfall, no concerns with these showers/storms are expected before they dissipate prior to sunrise. Models have been hinting at widespread valley fog across the region early this morning which is currently being backed up by observations across the region with visibilities below 2 miles. The idea that patchy dense fog is expected overnight remains the same with improvement occurring rapidly between 7 and 9 AM. The remainder of the day today looks rather uneventful as a secondary cold front catches up to the stalled frontal boundary and finally pushes east of the area. This will allow for cooler temperatures to dewpoints to descent across the region this afternoon. The more noticeable impacts will be tonight as decreasing dewpoints, light winds, and clear skies will allow for significant radiational cooling. For the most part, temperatures will drop into the low to mid 50s but the colder hollows of the Adirondacks and Northeast Kingdom could drop into the mid 40s. With significant drying at the surface expected, we don`t expect any fog to develop tonight or Friday morning. && .SHORT TERM /FRIDAY THROUGH SATURDAY/... As of 1252 AM EDT Thursday...Seasonal temperatures are in store for the day on Friday with plenty of sunshine in the forecast as we see the mid-level ridge begin to build back across the eastern US once again. However, we will see a disconnect between the subtropical ridge and this new ridge so we will continue to see lower dewpoints. The only concern for Friday will be low dewpoints and subsequent low afternoon RH values. Given the depth of the dry air and deep mixing expected in the afternoon hours, we could see dewpoints drop into the upper 40s Friday afternoon. This would yield RH values in the upper 20s to lower 30s. Luckily, winds will be light and should help limit fire danger. As we head into Saturday, we will see a strong surge of warmer air as the upper level ridge axis moves across the northeastern US. High temperatures will be noticeably warmer with highs in the mid 80s to lower 90s with the highest readings in the Champlain, Connecticut River, and St. Lawrence Valleys. Dewpoints will likely remain in the 50s so we don`t expect excessive heat indices in the afternoon but it`s always good to take breaks and drink plenty of water on sunny and hot summer afternoons. && .LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/... As of 1252 AM EDT Thursday...A general cooling trend with perhaps a more active weather pattern than we`ve had recently is expected for much of next week. An upper level ridge will build over the north central CONUS, which will place our region under progressive northwesterly flow. A front drops across our area on Sunday bringing the best chance for some widespread showers with thunderstorms possible in the afternoon. This front will usher in a cooler air mass. Temperatures will range from the 50s to 70s next week. There will be other chances for showers as well, but tough to pinpoint timing this far out. && .AVIATION /06Z THURSDAY THROUGH MONDAY/... Through 00Z Friday...A few showers linger across the region but should come to an end by 03Z. MPV/SLK and to a lesser degree, EFK and RUT will see some fog 08-12Z since rainfall occur at terminals with IFR and some MVFR. Lingering cloud cover could impede fog formation, if clouds out clear at the above terminals, LIFR is not out of the question. Southerly flow this evening becomes light overnight before turning northerly after 12Z. Outlook... Thursday Night: VFR. NO SIG WX. Friday: VFR. NO SIG WX. Friday Night: VFR. NO SIG WX. Saturday: VFR. NO SIG WX. Saturday Night: VFR. Slight chance SHRA. Sunday: VFR. Chance SHRA, Chance TSRA. Sunday Night: Mainly VFR, with areas MVFR possible. Slight chance SHRA. Monday: Mainly VFR, with local MVFR possible. NO SIG WX. && .BTV WATCHES/WARNINGS/ADVISORIES... VT...None.
