Saturday starts off dry, but the main focus this holiday weekend will be on the temperatures and the building humidity.
With that humidity, as a warm front waltzes in from the southwest by midday Saturday, we’ll see a spot sprinkle for the mountains and lakes region. Otherwise, mostly cloudy skies with a muggy feel by the late afternoon. Saturday’s highs will range into the 70s.
Sunday- the warm front slides to the north and everyone across New England will notice the shift in the humidity, however, a weak cold front from the west will start to advance closer to our area by the evening- meaning a clash between these two air masses will result in a few showers, ranging from the afternoon to evening hours. However, Sunday is not a washout by any means, there will still be plenty of dry time during the day for outdoor plans. Highs on Sunday will range into the 80s south, 70s north.
Sunday’s warm-up into a summery, almost tropical-like air mass will be short-lived as the remnants of Tropical Storm Nate will be bringing in the moisture for Columbus Day Monday. So, out of the long-holiday weekend, Monday will be the wettest and highs will be in the low to mid 70s.
Tropical Storm Nate is expected to cross into the warm Gulf waters, strengthening to a Cat. 1 Hurricane before making landfall along the Gulf Coast line of Louisiana, Alabama and Mississippi, and the far western Florida panhandle. Hurricane Warnings have been put into effect for most of those in the path of Nate. After making landfall late Saturday into early Sunday morning, Nate will weaken and also be swept up into southern New England by Monday and by that time will be sub-tropical.
New England needs the moisture as the most recent drought monitor places most of New England under unseasonably dry, we could see some locations reach at least 2+ inches through Tuesday, which could result in localized flooding in southern New England. The rest of the week contains a cool-down with highs into the 60s through Friday. Stay tuned for the latest updates on your forecast on the air, online and through the NBC Boston / NECN app.
