We just had a couple of bonus days with the late Summer feel. Today’s highs reached 70 for some suburbs NW of Boston. Boston itself saw a high of 66, 10 degrees from the record but almost 15 degrees above the average daily high! Sadly, a big change is marching east…a coldfront is slicing through the Ohio Valley and will be on our doorstep first thing tomorrow morning. Out ahead of the front, temps will remain balmy all night and into tomorrow morning. In fact, our high temps tomorrow will be set early in the morning because after the front slides through, cold air will come pouring in…temps will fall into the 40s by evening ending our warm spell.
Along the front, a solid line of showers has formed and will be moving through with the front. There may be enough instability to lead to some downpours or even a rumble of thunder with the initial line during the morning commute. With the wind shift into the NW by late morning, drier and cooler air will takeover leading to fewer and fewer showers for the afternoon.
For the next several days, strong high pressure will be situated off to our north and west with a general area of low pressure well offshore…the result, a persistent NE breeze coming in off the water keeping temps in the chilly 40s and lower 50s. While we won’t have any rain or snow, there is a good chance for low clouds to develop at times.
The quiet stretch will be welcomed but there are some signs that the East Coast could be threatened by a coastal storm during the Thanksgiving week. It does look as if the storm will form…it may or may not be too far offshore. Time will tell.
