Rain to Turn to Spring Snow for Some on Monday

Mild temps and sun-cloud mix expected this weekend, but rain and colder air move in Sunday night

Mar. 21, 2026 at 11:49am

This weekend will see mild temperatures and a mix of sun and clouds, but rain is expected on Saturday. The rain is likely to turn to snow on Monday as colder air moves in, with accumulation expected on non-paved surfaces. Temperatures will drop back into the 30s on Monday before gradually warming up through the week.

Why it matters

The late-season snow could impact travel and cause slippery conditions, especially on untreated surfaces. The changing weather patterns are a reminder that spring weather can still be unpredictable in the Northeast.

The details

Saturday's rain showers will move through the region at times, but the day won't be a complete washout. Highs will reach the low 50s, though southern New Hampshire may only see 40s. Colder air will pour in on Sunday night, causing the rain to turn to snow on Monday. The snow is expected to accumulate on non-paved surfaces like landscapes, trees, and some walkways, due to the high sun angle this time of year. Temperatures will drop back into the 30s on Monday before gradually warming up through the middle of the week.

  • Saturday will see rain showers at times throughout the day.
