MANCHESTER — The brutally cold “polar vortex” that kept most of New Hampshire in the single digits on Tuesday will give way to warmer temperatures today and the rest of the week, according to the National Weather Service.
“It could be above freezing, close to 40,” said James Brown, a National Weather Service meteorologist based in Gray, Maine.
The temperatures could climb even higher, as forecast models at the NWS website on Tuesday night showed Saturday and Sunday with potential high temperatures around 45 degrees for Manchester.
The polar vortex, a large mass of cold air, is normally centered over the North Pole and held in place by the jet stream over North America. But a high pressure system pushed the jet stream, and the vortex, over North America, resulting in record low temperatures across the Midwest, South and eastern United States.
Manchester-Boston Regional Airport was operating normally Tuesday, without backups, as only a handful of flights were canceled because of delays at O’Hare or Cleveland, where cold and wind were forcing closures and delays in transportation, schools and businesses.
One of the casualties of low temperatures in Manchester was a pipe that burst at the Manchester Animal Shelter on Dunbarton Road Jan. 3, collapsing part of the ceiling and forcing relocation of dogs at the shelter.
The shelter remained closed Tuesday, though adoptions were still happening, said Lori Taylor, director of development at the shelter.
Not only was the kennel area for the dogs damaged, but food, treats, Christmas gifts and cleaning supplies fell victim to the flooding. The shelter area for cats was not affected.
“The city is taking care of the immediate damage to the piping and ceiling,” Taylor said.
She said “a great response from the community” led shelter officials to decide to perform more cleaning and to spruce the place up. The shelter plans to do some interior painting this weekend and those interested in volunteering can email firstname.lastname@example.org for details.
