A FLASH FLOOD WATCH is in effect for Litchfield, Hartford, and Fairfield Counties through this morning.
TONIGHT & FRIDAY…
Ahead of a cold front, a strong southerly flow of tropical air has arrived, providing us with dew points in the 60s and lower 70s. This high level of moisture is fueling some downpours that could lead to poor drainage flooding or localized flash flooding this morning. Rainfall totals could range from 1-3” where the downpours occur, to well under an inch in other locations. There is also the chance for isolated wind damage, including a low risk for a brief tornado. Overall, severe weather will be isolated, not widespread.
Any threat for severe weather should end by late this morning, but a few showers will linger through the afternoon across eastern Connecticut. Meanwhile, western and perhaps central portions of the state will likely see some partial clearing. After temperatures dip into the 60s this morning, they should recover to 70-75 this afternoon. At least the front will bring relief from this high humidity. Dew point values should drop through the 50s in many parts of the state by this afternoon.
Tonight will be partly cloudy, cooler and drier. Temperatures will dip to 50-55 by dawn.
THE FIRST WEEKEND OF FALL…
The front bringing our wet/stormy weather will stall to our east, over Cape Cod by tomorrow morning. If a wave of low pressure develops on the front, showers could overspread Connecticut during the afternoon. How much rain we’ll get will ultimately depend on where low pressure forms and how strong it will get. Highs should be in the low and mid-70s.
If showers develop, they could linger into Saturday night but should be on their way out by early Sunday morning. Therefore, the second half of the weekend is looking good. Sunday should be partly sunny and seasonably mild with highs in the 70s. There may be a slight chance for a shower in the afternoon.
Another disturbance will swing through New England early next week. It could bring another round of showers from Monday afternoon through Tuesday morning. Temperatures will be in the 70s both days.
High pressure in Central Canada could deliver a shot of very cool air by Wednesday and Thursday. High temperatures could be held to the 60s both days, and the nights could be quite chilly with lows in the 40s. At least we’re expecting dry weather with a partly to mostly sunny sky.
