Hartford, Connecticut – A milder air mass building into southern New England ahead of St. Patrick’s Day will push much of Connecticut and Rhode Island toward rain during the day, but nighttime cooling could still allow brief rain-to-snow transitions between March 11 and March 17.
According to the National Weather Service Climate Prediction Center, both states remain 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. That warmer pattern favors daytime rainfall for most communities, though marginal overnight readings may still support wet snow in spots, especially inland.
In Hartford, Waterbury and along the Interstate 84 corridor, daytime highs climbing into the 40s could keep most precipitation liquid. However, if steadier precipitation lingers after sunset and temperatures dip into the lower 30s, wet snow could briefly accumulate on grassy areas and untreated secondary roads. In Providence and across much of Rhode Island, coastal influence should keep readings slightly milder, limiting snow potential mainly to heavier bursts during pre-dawn hours.
Along Interstate 95 from New Haven to Providence, reduced visibility is possible during steadier rainfall regardless of precipitation type. Inland hill towns in northwestern Connecticut face the greatest chance for minor slushy accumulation overnight.
Drivers across Connecticut and Rhode Island should monitor overnight and early morning road conditions where temperatures hover near freezing. Even brief wet snow can create slick spots on bridges and elevated highways. Additional updates are expected as the March 11-17 window approaches and system timing becomes clearer.
