BOSTON (CBS) – Rain, snow, wind, cold, bombogenesis, just another weekend in New England.
First, let me take you to almost a year ago, March 11, 2021. Don’t you remember? It was 74 degrees. That was the maximum temperature in Boston, a new record for the date. People were saying goodbye to winter. The next day it was 65 degrees and for the rest of March there were only a couple of days with temperatures below average. It was the unofficial start of a very mild spring (minus the abomination over Memorial Day weekend).
Fast forward back to reality. A year later, we’re talking about our second snow accumulation in the span of just four days and near-zero wind chills. Oh yeah, THIS is why we love living in New England.
Here’s what we’re looking at this weekend:
Your Saturday started out foggy and wet, with rain changing to a wintry mix, and finally, snowfall in the evening. Accumulation higher than a few inches occurred in parts of CT west to MA and VT, where the shift occurred earlier. Despite a final flurry of snow layering up to an inch or two (especially on higher ground), most of the snow will end between 8 and 9 p.m.
Expect slippery spots to develop on any untreated surfaces. Now the wind begins. Cold air rushes behind the storm. West-northwest winds blow between 20 and 40 mph throughout our area. Temperatures plummet and chills drop into the single digits after dark. Where snow has accumulated on trees (northern elevations in Worcester County and Western Massachusetts) there is a threat of some power outages with these strong gusts of wind.
The clouds will clear overnight and it will be a very cold and blustery night ahead with wind chill values ranging from -5 to 10 degrees on Sunday morning.
Temperatures are going to drop like a rock overnight and the mercury will drop into the teens and 20s on Sunday morning. Any untreated surface left wet overnight will freeze.
AND WHAT ABOUT THAT BOMBOGENESIS?
Fortunately, the storm’s “bombing” has just begun as it passed through southern New England on Saturday.
However, by the time this storm reaches the Canadian Maritimes, it will be a real beast. Central pressure is forecast to drop about 50 millibars in 24 hours (from Saturday morning to Sunday morning).
For an official case of bombogenesis, you only need about half that (24mb in 24 hours). Double bass? It’s not an official term, but maybe we should coin it. Regardless, this megastorm in eastern Canada will be responsible for bringing bitter cold and shearing winds Saturday night and most of Sunday. It’s not nice.
Again, any snow you may get this weekend will be gone early next week. Sunday will still be cold and windy with highs in the 30s, but sunset comes a little later (6:48pm) as we officially start daylight saving time.
The angle of the sun helps a lot this time of year after snow events like this. Starting Monday, the daily highs will be in the 50s and it looks like it will stay moderate through the week. Could this storm be our last real taste of winter? More on that next week.
