After a frosty start for many, plenty of sun will make for a noteworthy temperature recovery with highs reaching the 60s for many, regionwide, as high pressure – a dome of fair weather – begins a slow migration east of New England over the North Atlantic.
Eventually, this new position for the high pressure cell becomes important, as the clockwise flow of air around its center will induce a southerly wind flow to New England, further increasing the amount of mild air and moisture in the Northeast.

The milder change will be evident first: high temperatures likely to surpass 70 degrees on Friday for some, then Saturday, Sunday and Monday for many. It’s worth noting there’s some historical context here: our Tevin Wooten dug back into the record books and it turns out we’ve only seen eight November stretches of three or more consecutive 70 degree days.

Furthermore, if we hit or exceed 73 degrees those days in Boston, which is our First Alert Team’s forecast, this has only happened four times in recorded history! As for daily records, those will be tough to reach but not impossible, particularly Sunday when the record is 73, set in 2015.
As for rainfall, there’s not much in the forecast, but the increasingly moist air Sunday coupled with a slowly approaching cold front from the west will increase the chance of showers Sunday afternoon in northern and western New England. While it’s not likely these would sneak into eastern New England, it’s not a far distance in the world of weather, so we have introduced a shower chance even to the Boston area by late Sunday into early Monday.

As for a more meaningful pattern change, it still looks like much cooler air – closer to normal for this time of the year – returns for the middle and end of next week, toward the end of our exclusive, First Alert 10-day forecast.
