Burlington, Vermont – A milder air mass pushing into New England ahead of St. Patrick’s Day will tilt Vermont’s upcoming systems toward more rain, but nighttime cooling could still flip precipitation to wet snow between March 11 and March 17.
According to the National Weather Service Climate Prediction Center, Vermont remains within a 40-50% probability zone for above-normal precipitation during the 8-14 day period. Temperatures are projected to trend near to slightly above seasonal averages statewide. That warmer shift favors daytime rainfall in many valleys, though marginal overnight readings could still support rain-to-snow transitions.
In Burlington and along the Interstate 89 corridor, daytime highs reaching into the 40s may keep most precipitation liquid. However, if steadier precipitation continues after sunset and temperatures dip into the lower 30s, wet snow could briefly accumulate on grassy areas and untreated secondary roads. Along Interstate 91 from White River Junction north toward Newport, slightly cooler surface temperatures may allow more consistent snow during pre-dawn hours.
Higher elevations in the Green Mountains, including areas near Stowe and Killington, remain more likely to see accumulating snow with each passing system, especially overnight when temperatures cool more efficiently.
Drivers across Vermont should monitor overnight and early morning road conditions where temperatures hover near freezing. Even brief wet snow can create slick spots on bridges and mountain routes. Additional updates are expected as the March 11-17 window approaches and storm timing becomes clearer.
