Another nice day yesterday and although it wasn’t as warm as Saturday, it was still not the bitter cold we have been blasted with so much the past few weeks. If you went skiing, today was a stellar day on the slopes.
The northern branch of the jet stream, the one that brings mostly small weather events and cold to frigid air this time of year will take control of the weather through Tuesday. Within this flow of air, two small pieces of energy will produce a few hours of snow. The first of these was the snow we saw this morning. This snow won't amount to more than a coating to 1" in heavier bands. Parts of the North Shore had over 1/2 an inch as I write.
The rest of today will feature a lot of clouds and some breaks of sunshine. It won’t be very cold with highs in the 30s to low 40s. Winds will also be light. I don’t expect the snow to cause any issues with the commute.
overnight another one of these small systems comes down from Canada. The reason why they don’t bring much snow is they are coming from a very dry part of North America. Additionally, sometimes these systems can pick up some moisture off the Great Lakes, but since the lakes are basically frozen, there is not available moisture to contribute.
Tonight's system will trend further north, so I am just forecasting clouds and no snow with this one. If you are headed into Maine, there could be a coating to 2 inches up there.
Tuesday will turn mild as a southerly flow of air helps to boost temperatures in the 40s and lower 50s.
The next weather system, now over the Pacific Ocean rapidly moves across the country and brings a healthy shot of rain and snow to the region on Wednesday and Wednesday night before ending Thursday morning quite early.
It’s going to be a storm where it will depend on exactly where you are as to how much or how little snow you get. Areas furthest north and west of Route 495 have the greatest chance of seeing a significant snowstorm (over 6 inches) while areas along the coast and through Cape Cod have the smallest chance of a plowable storm.
It’s still very early in the accumulation game to start throwing out numbers. Early this evening the National Weather Service put out the image below trying to explain what we might expect from the storm. As you can see from the image there are basically three possible tracks the storm will take. The idea here is the further north the storm moves, the less snow places like Boston and Cape Cod will receive. The further south the storm track ends up, the more snow the coastline would get.
Once the storm departs, a quick shot of colder air will move into the region, there could be a possible warming trend into next weekend, more on that later this week.
I'll update my thoughts on the storm on Twitter @growingwisdom.
