A January thaw is moving in, slightly earlier than usual, WHDH-TV meteorologists say.

"Our annual January Thaw is upon us for the next several days," Channel 7 meteorologist Jeremy Reiner posted in his blog on Tuesday.

For the past three days, the entire staff of the Ch. 7 Weather Center has been blogging about the mild temperatures.

Typically, the January thaw happens between Jan. 20 and Jan. 26, Reiner said.

However, this winter has been mild.

Meteorologist Pete Bouchard said only nine days with below normal temperatures have occurred since the meteorological start to winter on Dec. 1.

The National Weather Service forecasts that high temperatures in Westborough will be in the 40s through Saturday, with the temperature getting into the 50s on Sunday.

Temperatures will again get into the 40s through at least Tuesday, the weather service said.

An even longer term forecast from Accuweather says that while temperatures will remain mild through mid-week next week, by next Friday, Jan. 18, temperatures will drop below freezing and will actually start a streak of below normal temperatures.
