Connecticut residents can enjoy a pleasant Saturday afternoon as temperatures climb into the 70s, but the calm is short‑lived. Meteorologists warn that a significant rain system will move in early Sunday, bringing heavy rain and the threat of flooding.

Saturday weather: mild and partly cloudy

After a chilly start to the day, the forecast calls for a gradual warm‑up. Expect highs in the low to mid‑70s with increasing cloud cover as the evening approaches. No rain is expected until after sunrise on Sunday.

Sunday rain and flood watch

Heavy rain is likely during the first half of Sunday, accompanied by a few rumblings of thunder. The National Weather Service has issued a Flood Watch for all of Middlesex and New London counties, as well as the southern portions of New Haven and Fairfield counties. The watch is in effect from 5 a.m. to 2 p.m. Sunday.

Rainfall totals of one to two inches are most likely across much of the state. However, the southeast region of Connecticut could see higher amounts, increasing the risk of localized flooding, especially in low‑lying areas and near streams.

What residents should do

Stay informed by monitoring local weather updates throughout the day. If you live in the affected counties, consider preparing for possible flooding by moving valuables off the ground, checking that sump pumps are working, and keeping an eye on local road conditions. Avoid driving through flooded roadways and follow any instructions from local emergency management officials.

Looking ahead to the workweek

After the rain passes, temperatures are expected to cool slightly as the workweek begins, with more sunshine returning to the region. Residents can look forward to clearer skies and milder temperatures later in the week.
