Lows will settle into the 50s and low 60s.
The setup — strong cold front, evening showers
Tuesday will be under the influence of high pressure, keeping the day partly to mostly sunny for most areas before the high pressure slides farther east, and a strong cold front pushes into the region from the west, increasing clouds. The cold front will spark scattered showers and a few rumbles of thunder across the region in the afternoon and evening.
Between late Tuesday and through the first half of Wednesday, rain totals should range from a half inch to an inch across Southern New England. Any rain we can get is much-needed precipitation to help fight again this drought.
One thing we’ll notice is the wind, which will increase to 10 to 15 miles per hour, with a handful of gusts reaching 20 to 25 miles per hour. It shouldn’t be too disruptive, but you’ll notice plenty of leaves flying around from the gusty conditions.
Before any rainfall arrives, this recent stretch of very dry weather and breezy conditions will keep a wildfire and brush fire risk in place across all six New England states.
This strengthening southerly flow will help bring additional moisture into the region overnight Tuesday into Wednesday.
Dew points will reach near 60 degrees on Tuesday, and the air will feel heavy on Wednesday. The strong cold front has very cool and dry air behind it. This will send dew points crashing into the 30s on Thursday.
Temperatures on Wednesday will return to fall-like averages, reaching the mid- to upper 60s, mainly due to overcast skies and rain for at least the first half of the day.
