753 FXUS61 KBTV 150551 AFDBTV Area Forecast Discussion National Weather Service Burlington VT 151 AM EDT Wed Jul 15 2026 .WHAT HAS CHANGED... As of 150 AM EDT Wednesday... Smoke has been added to parts of northern New York and Vermont Wednesday evening into Thursday ahead of a cold front. && .KEY MESSAGES... As of 150 AM EDT Wednesday... 1. Storms angling south could produce severe weather for a few more hours. 2. Smoky conditions through Thursday until a reinforcing frontal boundary brings rain and pushes it south. 3. Seasonable temperatures and showers likely this weekend with possible thunderstorms, then another round of showers and potential storms early next week. && .DISCUSSION... As of 150 AM EDT Wednesday... KEY MESSAGE 1: Warning operations is underway. Strong to severe thunderstorms are favoring southern area, and have leveled off some in intensity compared to the significant storm that cross Russell, DeKalb, and Ogdensburg in New York. After 4 AM, most convection should be well away from the region. Until then, we continue to monitor for damaging winds and hail up to 1". A few showers may rotate around an upper trough in northern Vermont, but no thunder expected. KEY MESSAGE 2: Wildfire smoke will move back into the region late Wednesday afternoon and overnight, spreading across Vermont and northern New York into Thursday. Poor air quality will be possible, but temperatures will be in the upper 70s to mid 80s for the most part. With diurnal heating, some showers and storms will develop along the cold front shifting south, but it will not have nearly as much instability as this evening`s activity. Cooler conditions ensue. KEY MESSAGE 3: Longwave troughing will cross the region this weekend as two surface low pressures, one in the Great Lakes and one along the mid-Atlantic coast, will interact while tracking through the Northeast. Global deterministic models are fairly aligned in this idea at the moment, providing increased confidence of showers and thunderstorms Saturday afternoon into early Sunday morning. The probability of an inch of rainfall within 24 hours from this system is around 5-20%. More likely 24 hour amounts will fall somewhere between 0.33 and 0.66 inches. Depending on the storm track and timing of any associated frontal passages, the threat of strong to severe storms will be watched, but the threat should remain on the lower side due to a cooler and less humid airmass. Temperatures will remain around seasonal normals in the mid 70s to lower 80s both Saturday and Sunday with nighttime lows in the upper 40s to lower 60s. Next week should start briefly dry on Monday with temperatures increasing into the upper 70s and 80s, then another trough and northern stream low pressure swing through to increase chance of precipitation again on Tuesday. && .AVIATION /06Z WEDNESDAY THROUGH SUNDAY/... Through 06Z Thursday...Scattered storms will move through the region during the next few hours, bringing localized IFR visibility and frequent lightning. There will also be some gusty erratic winds. This is expected at BTV and PBG between 6-7Z and RUT before 9Z. These storms exit by around daybreak. VFR conditions are expected to prevail through tonight. Winds will increase into the 15-25 KT range out of the northwest today, before generally going light and variable tonight. A few pockets of LLWS will exist for the rest of the night, before going away this morning. Outlook... Thursday: VFR. Chance SHRA, Chance TSRA. Thursday Night: VFR. NO SIG WX. Friday: VFR. NO SIG WX.
