Changes are Coming...
I honestly got a little depressed when the sun set Saturday afternoon...that was one of the finest days ever...for me, right up there with that stretch over Columbus Day weekend. The high was 60...just shy of the record. Today's high was 40 degrees...still above the average high but it felt so much colder, our blood truly has thinned out due to the abnormal warmth. Well we will see one more warm up, a short-lived one at that, with highs in the 40s tomorrow before we start consistently feeling like Winter and probably start looking like it too! Strong high pressure, and its corresponding cold air to our north will get drawn into the Northeast by Thursday morning as low pressure is developing to our south. Air likes to flow from high to low pressure so we will see that cold drain into the Interior especially. Once it's there, it will be tough to dislodge with the locking high to our north...this is known as cold air damming. Consequently, the moisture at the start of the next storm will likely start, for most in New England, as snow before changing over to rain for most in Southern New England. This system will be juicy so there will several inches of snow for Northern New England (great news for the ski resorts heading into a three day weekend) and a solid soaking of rain for Southern New England. There may be some minor accumulations for the suburbs to the north and west of Boston at the start very early Friday morning before changing to a cold rain.
Following the storm...litterally on its heals...will be another piece of upper level energy for Friday. This represents the leading edge of more typical Winter cold that will likely have staying power through the rest of the month. Along with delivering a pattern change, it will likely supply us with snow showers or squalls during the day.
The weekend appears quiet but cold...highs for most will stay in the 20s both Saturday and Sunday.
