Ready for the first snow of the season?
The National Weather Service issued a special warning Monday night about quickly dropping temperatures that will herald snow early Tuesday and into the morning commute.
A strong cold front moving south and east will bring rain about midnight, with a "quick changeover" to snow around 4 a.m. to 6 a.m. Tuesday, said Lauren Nash, weather service meteorologist based in Upton.
But just before the snow falls, the temperatures will drop like a lead weather balloon. "Once that cold air comes in -- it'll over an hour or two -- we could drop three to five degrees an hour," she said.
Temperatures could dive from 45 degrees to 35 degrees in two hours, Nash said.
The snow would fall Islandwide, with around half an inch on average forecast through midmorning, with slightly less closer to the city, the meteorologist said.
Look for accumulations mostly on grassy surfaces, she said.
"A gusty northwest wind will result in blowing snow as it falls during the commute," the weather service said.
Monday night's low temperatures are expected to be 33 to 35, Nash said, and Tuesday's highs around 41 to 42.
A freeze watch remains in effect from 10 p.m. Tuesday to 10 a.m. Wednesday, meaning freezing temperatures are possible and could kill crops and other sensitive vegetation, the service said. Temperatures are expected to be in the mid-to-upper 20s, and in the lower 20s in the Pine Barrens, the service said.
