O.k. time for a little honesty. I have been delaying this blog for probably close to 3 days now. And the reason for the delay is simply that I had no clue what was going to happen with the potential storm for Tuesday. For what has seemed like the last 2 weeks we have been targeting the Tuesday/Wednesday time frame for a potential system to impact New England. And for the longest time it appeared that this system would pass to our northwest and bring us rain. Well just as I was ready to type this blog and forecast rain for Southern New England the computer guidance decided to completely change it’s mind and bring the system south of New England……giving us the chance at snow.
And for the last couple days now, the computer guidance has been flip flopping with either idea, but finally it appears that some form of a consensus is being found. It looks as if most of Southern New England has a chance at seeing some flakes fly Tuesday afternoon and evening; but with only places say…..south of the Mass Pike having a chance of accumulating snowfall.
Image above is a very crude description of what should happen. The orange X over the Dakota’s represents a piece of energy. This piece of energy is going to drop down through the Midwest where a low pressure center should begin to form near the Ohio River Valley. This low pressure should track to the east and out into the Atlantic; giving locations on the northern side a chance at some light snow. Places in the lighter blue have a chance at seeing flakes fly, while places in the darker blue have a chance at seeing accumulating snow. Of course with everything in the world of weather prediction there is the chance that this could change and it probably will.
But first, it’s going to be cold today, temperatures will struggle to reach 40 as we experience our coldest air mass of the season after yesterday’s cold front. Tonight will be clear and cold. As evidenced by the last few times we have had clear & dry nights, our temperatures will be allowed to fall fairly far. Lows around 20 would not be a surprise.
Another clear day on Monday before we deal with our small storm on Tuesday. Followed by a fairly cold air mass to end the work week. Then it isn’t until Saturday that we see our next chance of a storm.
Looking ahead into December, after a brief warm up during the first week it appears that the overall atmospheric pattern is going to be conducive for cold to drop down out of Canada and for potential storms to impact our region. It certainly looks as if the month of December is shaping up to be an interesting one; hopefully things can pan out and we can see some good snow storms.
