The National Weather Service says record or near-record warmth is in store for northern New England for a day.
Temperatures were expected to rise into the 50s and 60s, and possibly 70 in parts of southern New Hampshire on Wednesday.
In Burlington, Vermont, it was 61 on Wednesday morning, already breaking the record for the date. It reached a record 59 degrees in Burlington on Tuesday.
The snowmelt may lead to some ice jam flooding in the region.
Typical winter weather is returning Thursday, with highs in the 30s.
