Arctic air had a firm grip on the Pioneer Valley this Christmas as we woke to temperatures in the teens to some single digits and the mercury struggled to reach 20 degrees this afternoon. Sunny skies the first half of the day have now given way to mostly cloudy skies as evening approaches.
Skies become mainly overcast tonight ahead of an approaching weak weather disturbance that will have minimal impacts across the area during Thursday. Temperatures are still cold tonight, just not as cold, and then become milder on Thursday. Intermittent light snow breaks out early on Thursday but it should be nothing more than a nuisance, although some secondary roads could become slippery for a time. This will have very little impact on travel as we head back to work, the malls or depart home from your Christmas visit with relatives and friends. Many locations should see a coating of snow to perhaps an inch or two in the hills. There is a chance of a few raindrops mixing in for good measure, especially along and south of the turnpike, before the precipitation ends by late in the day.
Its all out of here early Thursday night as the system moves quickly toward Nova Scotia with another ridge of high pressure building in Friday and Saturday. Fair weather into Sunday is expected before a developing storm in the Gulf of Mexico approaches by late in the weekend. Early consensus is that the storm will move well offshore Sunday night with southeast Massachusetts having the risk of any impacts from this storm. This can change and will be watched late week for any changes in the computer models.
