Manchester, NH – Freezing nighttime temperatures followed by a sharp weekend warmup will bring contrasting autumn conditions to Manchester and the surrounding southern New Hampshire area through Monday, Oct. 26. The National Weather Service expects temperatures to fall as low as 29 degrees Saturday night before sunshine pushes afternoon highs toward 68 degrees Monday. The return of below freezing temperatures could threaten unprotected vegetation, while the warmer afternoons will offer a brief break from the late October chill before another cooldown arrives Tuesday.
According to the National Weather Service forecast for Manchester, Friday night will bring mostly clear skies and a low near 31 degrees, followed by an even colder Saturday night near 29 degrees. Temperatures are expected to rebound significantly by Monday afternoon, reaching approximately 68 degrees under sunny skies. The forecast then calls for a high near 55 degrees Tuesday, followed by another cold night around 28 degrees.
Freezing Nights Give Way to a Warm Monday Friday, Oct. 23, will feature sunshine and a high near 56 degrees, with north winds around 5 mph. Temperatures will fall below freezing Friday night as winds become calm, creating conditions favorable for frost formation. Residents with sensitive outdoor plants or exposed seasonal vegetation should consider taking precautions before temperatures drop.
Saturday, Oct. 24, brings sunny skies and a high near 59 degrees. North winds will become northwest around 5 mph, while clear skies and calm conditions return Saturday night. Temperatures are expected to reach approximately 29 degrees, making it the coldest night of the weekend and increasing the likelihood of frost across exposed surfaces.
Sunday, Oct. 25, marks the beginning of a noticeable warming trend as temperatures climb to approximately 65 degrees under sunny skies. Calm winds should accompany the warmer afternoon before temperatures fall near 35 degrees Sunday night. The improving daytime conditions will continue Monday, when Manchester could reach 68 degrees, its highest temperature in the supplied forecast period.
Temperature Swings Could Affect Outdoor Plans The contrast between Saturday night's 29 degree low and Monday's 68 degree high represents a 39 degree difference across roughly two days. Although this is not a sudden temperature change within a few hours, the shift could be noticeable for residents planning outdoor activities, working outside or traveling during the early morning.
Drivers using Interstate 93, Interstate 293 and nearby Route 101 should prepare for freezing temperatures during late night and early morning travel. Frost may develop on parked vehicles, requiring additional time to clear windshields. However, the supplied forecast does not indicate freezing precipitation, snow accumulation or widespread icy roadway conditions.
Tuesday Brings Another Significant Cooldown After Monday's warmer afternoon, temperatures are expected to fall back to approximately 55 degrees Tuesday, Oct. 27. That represents a 13 degree decline in daytime highs from Monday. Tuesday night will become mostly clear, with temperatures dropping near 28 degrees, bringing another round of freezing conditions.
Wednesday should remain cooler, with a high near 54 degrees and a nighttime low around 31. Thursday could bring a modest rebound to approximately 59 degrees under mostly sunny skies. No significant storms or precipitation are indicated in the available forecast through Thursday.
The combination of freezing nights and milder afternoons makes layered clothing particularly important during the coming days. Residents should also protect vulnerable outdoor plants and check any exposed seasonal water equipment before temperatures fall below freezing.
