BURLINGTON, Vt. – Summer warmth won’t last long for Vermont. By Labor Day, sunshine gives way to cool September air sweeping across the state, dropping overnight lows into the 50s and hinting at fall’s arrival. Drivers on I-89 and local back roads should prepare for breezy mornings and reduced visibility from patchy valley fog early next week.
According to the National Weather Service in Burlington, Monday will stay sunny and mild with highs near 79 degrees. By Tuesday, cooler air arrives from the Midwest, bringing daytime highs closer to 80 but nighttime lows falling into the upper 50s. The shift will be felt most in rural areas, where overnight chill may dip near 53 degrees.
Residents planning outdoor gatherings for the holiday should enjoy warm, clear conditions on Labor Day itself. However, campers and early commuters will notice brisk mornings starting Tuesday. Winds shifting south to north will enhance the cooling trend, with gusts around 10 to 15 mph midweek.
The broader weather pattern shows a large pocket of below-normal temperatures gripping the eastern U.S. from September 4 through 8. Vermont sits on the edge of this system, likely keeping highs moderate but ensuring noticeably cooler nights.
Safety officials urge drivers to use caution on early morning commutes, as cooler nights often bring patchy fog to the Champlain Valley. Those with outdoor plants or late-summer gardens should also prepare for the chill.
Cooler air will stick around into late week, with showers returning by Thursday and Friday. Additional advisories may be issued if temperatures drop further.
