A FLASH FLOOD WATCH is in effect for Litchfield, Hartford and Fairfield counties until this morning.

TONIGHT AND FRIDAY …

Before a cold front, a strong flow of tropical air from the south arrived, providing us with dew points in the 60s and 70s. This high level of humidity fuels some downpours which could lead to poor drainage flooding or flooding. flash located this morning. Precipitation totals could range from 1 to 3 inches where the showers occur, to well under an inch in other places. There is also a risk of isolated wind damage, including a low risk of a brief tornado. Overall, severe weather events will be isolated and not pervasive.

Any threat of severe weather is expected to end by late morning, but a few showers will persist throughout the afternoon in eastern Connecticut. During this time, the western and perhaps central parts of the state are likely to experience some partial clearing. After temperatures drop into the 60s this morning, they are expected to return to 70-75 this afternoon. At least the facade will provide relief from this high humidity. Dew point values ​​are expected to drop into the 1950s in many parts of the state by this afternoon.

It will be partly cloudy, cooler and drier tonight. Temperatures will drop to 50-55 by dawn.

THE FIRST FALL WEEKEND …

The front bringing our rainy / stormy weather will stop to our east, over Cape Cod by tomorrow morning. If a low pressure wave develops across the front, showers could extend over Connecticut during the afternoon. How much rain we get will ultimately depend on where the low pressure forms and how strong it is. Highs should be between the low to mid-70s.

If showers develop, they could linger until Saturday evening, but should be close to leaving early Sunday morning. Therefore, the second half of the weekend is looking good. Sunday should be partly sunny and mild with peaks in the 70’s. There may be a slight chance for an afternoon shower.

NEXT WEEK…

Another disruption will occur in New England early next week. This could bring another round of showers from Monday afternoon to Tuesday morning. Temperatures will be in the 70s on both days.

High pressures in central Canada could deliver a breath of very fresh air by Wednesday and Thursday. High temperatures could be maintained until the 1960s on both days, and nights could be fairly cool with lows in the 1940s. At least we expect dry weather with partly to mostly sunny skies.
