New Hampshire – Cold air bites early, and breath hangs visible under streetlights. Snowflakes drift lightly at times, signaling a winter pattern tightening its grip as post-Christmas travel ramps up.
Across southern New Hampshire, temperatures remain locked well below freezing through much of the period. Early readings sit near 20 degrees, with wind chills dipping lower. Light snow chances linger today, though accumulations remain minimal. Roads may stay mostly passable, but untreated surfaces could turn slick.
By Friday, clouds increase and highs struggle to reach the low 20s. Another round of snow becomes possible late, especially into Friday night. While snowfall amounts appear light, even brief bursts could reduce visibility on I-93, Route 101, and Route 3, particularly after dark.
Saturday brings some improvement. Skies turn brighter, and highs climb into the mid-20s. Conditions feel brisk but manageable for travel. Crews may use the break to address lingering icy patches from earlier snow.
Sunday stays partly sunny, with temperatures rebounding near 35 degrees. Melting begins during the afternoon, leaving wet pavement behind. That setup matters. Meteorologists are now tracking a developing system that could arrive Sunday night into Monday.
Forecast models show a wintry mix developing, including snow, sleet, and freezing rain, before transitioning to rain Monday morning. Ice accumulation remains possible, and precipitation chances rise near 80 percent. Travel conditions may deteriorate quickly, especially during early-day commutes.
By Monday afternoon, temperatures climb near 40 degrees, allowing rain to wash away snow and ice. Still, refreezing remains possible later as colder air follows.
Residents should plan carefully. Allow extra travel time late Sunday and Monday morning. Keep winter gear in vehicles. Conditions may change fast as winter weather reasserts itself during the final week of December.
