You Betcha (It’ll Be Cold Again)

You Betcha (It’ll Be Cold Again)

After yesterday’s (somewhat unexpected) high temperature of 60°F (+1.5 standard deviations from the norm), you knew this unseasonably warm air wouldn’t last long. After November’s below-average warmth, deep down you knew it’d be cold again. In this case, again starts Friday. After that, the jet stream is forecasted to dip southward, bringing the colder Canadian air into New England and persisting for more than a week. Likely as a result, the Climate Prediction Center (CPC) is predicting a moderate chance that this month’s average temperature over the eastern-half of the United States to be below normal. Furthermore, since the jet stream is a “highway” for low-pressure systems to travel on, storms will likely pass by Boston every three days or so. Likely as a result, the CPC is predicting above-normal precipitation for the next couple of weeks. So the upshot: there’ll be more than a handful of opportunities for you see snow this month.

In the meantime, before Friday, a high pressure to our south will keep us sunny and dry for today and tomorrow. In fact, Wednesday looks like not only the pick of the week, but the best combination of sunny skies and temperatures above the 40s for the next two weeks. So enjoy today and tomorrow because you betcha it’ll be cold again.
