Manchester, NH – Southern New Hampshire woke up to a biting chill this morning as Thanksgiving-week travelers stepped out under mostly cloudy skies. With temperatures hovering around 27°F before sunrise, the region is bracing for a wet, unsettled stretch through midweek, followed by a sharp drop in temperatures just in time for the holiday. While roads remain clear for now, officials warn that conditions could change quickly as a developing storm system approaches New England.
Early Week Weather Overview
A noticeable chill settled over the region before dawn, acting as a reminder of the winter conditions on the horizon. According to the National Weather Service, light rain is expected to develop later today, gradually increasing in intensity through Tuesday night and early Wednesday. Temperatures will briefly surge into the upper 50s, offering an unseasonably warm break before a sweeping cold front arrives late Wednesday.
Forecasters note that this front will bring gusty winds, falling temperatures, and a rapid shift toward colder air, setting up a crisp and bright Thanksgiving Day.
Timeline of Weather Changes
The storm system approaching New Hampshire will introduce multiple phases of disruptive weather:
- Today: Cloudy skies with highs near 51°F.
- Tonight into Wednesday morning: Periods of rain, heavy at times, reducing visibility for early travelers.
- Late Wednesday: Arrival of a cold front, strong wind gusts, and a significant temperature drop.
- Thanksgiving Day: Mostly sunny but chilly, with highs near 45°F and lows falling into the upper 20s.
This rapid warm-to-cold transition could produce slick spots in areas where wet surfaces freeze overnight.
Travel Impacts Across Southern New Hampshire
Travelers across major corridors — particularly I-93 and Route 3 — should be prepared for periods of slowed traffic during the busiest travel window of the week. Weather officials warn that puddling, reduced visibility, and long stretches of wet pavement could delay evening and early morning commutes.
“Drivers should remain alert for changing road conditions, especially during the Tuesday night and Wednesday morning peak travel hours,” the National Weather Service advised in its regional update.
As temperatures fall rapidly late Wednesday, elevated areas and untreated surfaces could develop light frost, increasing the risk of slippery spots.
What Officials Are Saying
Local agencies emphasize safe travel practices during this dynamic weather pattern. Road crews are preparing for fluctuating temperatures and the potential need for overnight treatment on bridges and ramps. Meteorologists also highlight the risk of strong wind gusts accompanying the front.
“Expect breezy conditions late Wednesday that may impact high-profile vehicles,” forecasters noted.
“The cold air settling in behind the system will make Thanksgiving feel significantly colder than earlier in the week.”
Key Weather Facts for Travelers
- 27°F early morning low in Manchester
- Rain developing today, increasing overnight
- High 58°F expected before the cold front on Wednesday
- Gusty winds late Wednesday into night
- Thanksgiving Day highs near 45°F, lows upper 20s
- Risk of frost and freezing surfaces after the front passes
Why This Pattern Matters
Thanksgiving week is historically one of the busiest travel periods in New England, and even moderate rain can create significant disruptions. Wet leaves, early-season frost, and temperature swings all contribute to hazardous driving conditions.
With colder air expected to remain in place into early December, this week’s weather may be a preview of the winter pattern set to dominate the region.
Climatologists note that late November often brings mixed precipitation to higher elevations. This aligns with early models suggesting a weak late-weekend system that may produce light rain or snow across northern New England — especially above 1,500 feet.
Extended 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
Conclusion
With millions expected to travel across New England this week, weather conditions will play a major role in shaping holiday plans. From heavy rain to a sharp cooldown, Southern New Hampshire residents are encouraged to monitor forecasts closely and prepare for slower travel during peak hours.
