Record Cold Tonight; Snow Likely For Monday
With clear skies and diminishing wind temperatures will free fall tonight. Readings have the potential to fall well below zero! In fact, record cold for March 1st is not out of the question. The record low temperature at Westover AFB is 3 set back in 1994. I’m forecasting a low of 4 below zero!
After a frigid start tomorrow, with temperatures falling below zero (we could approach the all-time monthly low), it looks much less frigid during the rest of the weekend. Tomorrow will feature a mix of sun and clouds with temps. reaching into the lower 30′s by the afternoon. On Sunday a cold front will sag through the area and will bring us some snow showers or a period of light snow during the day. This could give us a minor accumulation during the day on Sunday as colder air seeps in.
The plot will thicken Sunday night into Monday! The front will stall south of New England, as a developing area of low pressure slides up the east coast and along this front. Where this front sets up and how this developing storm interacts with an Arctic High Pressure system, over eastern Canada, will determine how much snow we end up seeing on Monday. If this storm stays “progressive and flat” then snowfall amounts will be light. However, if this storm comes close enough and “winds up” then snowfall amounts would be significant! As this point it’s just to early to say. Our compute guidance has been shifting a bit over the last day so stay tuned! Things will come more into focus over the next day or so.
Here is what we know, with some degree of certainty: There will likely be at least “some” accumulating snow leading to at least a minor accumulation. Since the Arctic air will be in place the snow will be light and fluffy in nature. Temperatures will likely stay in the low to mid-20′s on Monday. Also, as this storm moves away another batch of Arctic air will pour into western Mass, keeping temperatures in the 20′s both Tuesday and Wednesday.
