Manchester, NH – A biting chill grips southern New Hampshire this morning as travelers head out under mostly cloudy skies. At 27°F before sunrise, the air carries a hint of what’s to come — a wet midweek followed by a sharp cooldown just in time for Thanksgiving. Roads are clear for now, but drivers should prepare for changing conditions as a storm system pushes through New England.

According to the National Weather Service, light rain develops later today and continues through Wednesday morning, possibly heavy at times. Highs will climb into the upper 50s before a cold front sweeps in late Wednesday, bringing gusty winds and dropping temperatures quickly toward freezing. Thanksgiving Day will turn bright and mostly sunny, but highs near 45°F and lows dipping into the upper 20s will make it feel brisk.

Travelers should be alert for wet roads Tuesday night and early Wednesday, especially along I-93 and Route 3 where puddling and reduced visibility could delay trips. The region then transitions into a colder, drier pattern — an early taste of winter that could linger into December.

By late weekend, models suggest another weak system with light rain or snow possible across higher elevations in northern New England.

Five-Day Outlook:

  • Today: Mostly cloudy, high 51°F.
  • Wednesday: Cloudy with rain, high 58°F.
  • Thanksgiving Day: Mostly sunny, high 45°F.
  • Friday: Partly sunny, high 40°F.
  • Saturday: Sunny and cold, high 38°F.
