BOSTON (CBS) – The variability and uncertainty in Boston’s weather really starts to get steamy in December. As average temperatures start to drop and the jet stream starts to get more amplified, the frequency of the days wind will increase noticeably.
So it’s no surprise that things can be so changeable and unsettling that there’s a chance of strong winds over Eastern Massachusetts on Monday. A wind warning is in effect for coastal areas of southeastern Massachusetts, Cape Cod and the Islands, where cores of the strongest winds are likely.
You could blame it on a major storm system that made a path across the Great Lakes above and into northern Ontario. That storm will sweep a cold front across Western New York on Monday, then head east into Southern New England late Monday night.
A shower will affect morning commutes with wet roads and lower visibility. There might even be a thunderclap. There will then be a lull in activity with mostly cloudy skies breaking up from midday through afternoon, before showers return late into the evening and Monday night.
The times on this system couldn’t be worse for those who will likely head to Buffalo for the Patriots Bills big game Monday night. Weather conditions For that game there will be no shortage of challenges. For those traveling there, be prepared for 40-50 mph gusts that will likely push sleet-effect lake winds into Orchard Park along with 30 degree air and cold wind in the 20s at the time of the game.
In eastern Massachusetts, the strength of Monday’s gusts will be a function of cloud cover. The less cloud cover there is during the day, the greater the chance that the sun will help mix the atmosphere pulling down the surface some of the stronger winds in front of the strong cold front associated with this storm system. This region of stronger upper-atmospheric winds, known as the low-level jet stream, is forecast to contain winds capable of producing gusts of 50 mph or more at the surface in Eastern Massachusetts.
The timeframe to watch for the strongest gusts on Monday will be between 4 p.m. and 10 p.m. The areas likely to experience some of the strongest gusts of the 50 mph range will be zones coastal SE Massachusetts, Cape Cod, and the island. Strong gusts like these can knock down some tree branches and can also mean isolated power outages.
Showers will be accompanied by winds blowing through the area late Monday afternoon and evening, but the effects of that rain will be small. This road ahead will certainly be remembered more for its winds than for the wet weather it produced, although an individual thunderstorm early in the day cannot be ruled out.
And whenever there is wind, the temperature changes accordingly. There’s a good chance that some localities further down the South Coast and Cape see high temperatures before the cold snap in the lower 60s! This was followed by a sharp drop in temperatures and a return to the more frequent cold levels of December on Tuesday.
Bottom line: Get ready for some “changeable weather”!
