SHREWSBURY, Mass. - While central Massachusetts is enjoying a warming trend this week, Shrewsbury weather analyst Jim Arnold has a warning -- don’t get used to it.
While temperatures are expected to rise through the 40s and possibly into the 50s into early next week, Arnold stated: “There are indications that bitter cold arctic air will plunge southward into the upper Plains around mid-week next week, and the cold air will push to the East Coast by the end of next week.”
It gets worse. Arnold is predicting more arctic air to follow, and much of the United States. will be gripped by below-normal temperatures by the end of January.
“It appears that we will keep some snow cover, which will keep temperatures lower than if we had bare ground. There could be several nights where temperatures in the usual area cold spots drop well below zero beginning around January 20,” he said. “Should this pattern lock in, we could see very cold weather well into February.”
This could mean cars could have trouble starting. It also could mean pipes may freeze.
“Right now, I can’t say with any certainty whether or not this cold pattern will bring storminess with it,” Arnold said. “A thermal boundary will exist along the leading edge of the arctic air and this could roughly be the track of storminess that develops along the Southeast coast of the U.S. The question is whether the cold will be robust enough to drive the thermal boundary far enough offshore to keep potential storminess to our south and east. As a rule, this is what happens, but each situation is different and this needs to be carefully watched.”
