Merry Christmas to all celebrating the holiday today. It is such a wonderful time to cherish the people you love, count all the blessings in your life, and focus on what really matters in this short passing uncertain life we live. Hard to imagine a day possibly being better than the weather is going to be today. Only 4 times since 1900 has it been above 50 degrees on Christmas day in Concord, MA. Today will be the 5th. The record is 56 degrees set in 1889 and we will come very close to breaking that. This could end up being the warmest Christmas day of our lifetime with sunshine and highs in the mid 50's, near 60 in southern New England.
High pressure will slide over us Saturday with more sun, and slightly cooler air in the 40's. Clouds will be increasing during the afternoon ahead of a warm front which will bring in a period of rain late Saturday night through the early morning hours of Sunday. This front will stall over us Sunday with plenty of clouds and maybe a few periodic showers. It does not look like a washout Sunday. In fact, depending on the placement of the front, some areas could climb back into the 50's in SNH. It will be a better bet across southern New England. A wave of low pressure will push through the north country Sunday and pull away. Much cooler air will be directed back into New England starting Sunday night. Snow showers will develop in the mountains.
A strong high from Canada will follow in behind this front and direct a significant cold shot of air over New England Monday. Plenty of sunshine, but highs will only be able to reach 32. It will be a reminder that yes, we really are just getting started in this winter season. The cold dome of air will be in place so when our next batch of moisture arrives Tuesday, we are talking about the the very real potential of our first accumulating snow of the season.
A wave of low pressure will track towards the Great Lakes, while a secondary low will generate off the mid-Atlantic coast. Snow will overspread the region Tuesday morning and will become heavier during the midday and afternoon. There is the potential for seeing up to 6" or more of snow along with this. As the storm weakens and pulls away Tuesday night and early Wednesday, we could see tom mixing to rain in far southern reaches of the state. Freezing rain/drizzle could be an issue early Wednesday morning. Roads will become snow covered and Wednesday morning's commute could be slow, delayed and slippery with temps in the 20's.
It is too early for real details regarding an event which will happen Tuesday. Too much can change. Talking about where snow rain lines will set up, how much snow will fall, the timing, it is all pure speculation this far out. We can talk about potential, and this has the potential to be our first snow storm of the season. Not a big storm, but it could end up being a moderate thump of snow, which is something which always takes a little getting used to for the first snow of the season.
