Islip, NY – A surge of springlike warmth could take hold across Long Island within days, accelerating snowmelt and increasing the risk of standing water on major roadways before St. Patrick’s Day celebrations begin.
According to NOAA’s 8-14 day outlook issued February 26 and valid March 6-12, there is an 80-90% probability of above normal temperatures stretching from New England through Florida and west into parts of the Midwest. Long Island sits firmly within that high-confidence zone, signaling highs that could climb well above early March averages across Nassau and Suffolk counties.
In Islip and Brookhaven, where early March highs typically hover in the low to mid-40s, afternoon readings could trend significantly milder. Huntington, Riverhead and surrounding communities may also see warmer overnight lows, reducing freeze concerns but speeding up the thaw of any lingering snowpack.
The precipitation outlook adds another impact. NOAA favors above normal rainfall across much of the East Coast during the March 6-12 window. While the heaviest precipitation probabilities are centered over the Great Lakes, Long Island remains in a pattern supportive of repeated rain events moving up the coast.
That combination of warmth and steady rain could lead to minor urban and poor drainage flooding, especially along Sunrise Highway, the Long Island Expressway and low-lying coastal roads. Residents should clear storm drains, secure outdoor items and avoid driving through water-covered streets during heavier downpours.
This warm, unsettled stretch is expected to persist through March 12, with additional updates likely as the timeframe approaches and confidence increases.
