Boston MA snow forecast for Wednesday, March 9, 2022
Although we have had spring weather for the past few days, it will soon look like winter again. A storm system that is not very intense will move south to New England later in the day and move into the Atlantic overnight. This track will keep us on the colder side of the storm and allow precipitation to spread across the region this afternoon.
How much snow?
In March and April, it is very difficult for snow to accumulate on the roadway. This is because there is residual heat in the asphalt which tends to melt the snow when it falls. It would need to be several degrees below freezing before we really see a lot of buildup on the roads, but as snow is going to fall with temps in the 30s today, I’m expecting 1 to 3 inches, with less on the roads. A few places in more hilly terrain southwest of Boston and parts of Rhode Island and Connecticut can reach 4 inches.
The snow will be heaviest in the afternoon and will calm down overnight.
The snow will start in the late morning or early afternoon, moving up from the south, then end between 7 and 9 p.m. from west to east. I think the heaviest snowfall will fall between about 2 and 6 p.m. This is when travel will be most affected.
Late tonight skies will clear and temperatures will drop back to just below zero. When you get up on Thursday morning, check your driveways and sidewalks, as there may be residual ice. Once the sun angle gets higher on Thursday, the snow will begin to clear quickly.
I expect that by the end of the day it will feel like spring again and not winter. Temperatures will reach near 50 on Thursday and Friday.
The weekend will be rainy and cold
It will be wet on Saturday with a storm system moving through the heart of New England. It will rain most of the day with temperatures in the 50s. Some areas can get an inch of precipitation – not enough for flooding, but enough for large puddles. Things will cool off on Saturday evening and the rain may actually end in a brief spell of snow.
It will be cold and windy on Sunday as a brief bout of arctic air arrives. Temperatures on Sunday won’t go above the lows to mid-30s, and with the wind blowing it will feel like a teenager.
The weather will be nicer early next week.
One final note: don’t forget to set your clocks back one hour before you go to bed on Saturday nights. We resume summer time and “spring ahead” on Sunday.
