Strong thunderstorms that brought more than an inch of rain Thursday, ended days of record high temperatures.

The National Weather Service and the Community Collaborative Rain, Hail and Snow Network said Norwalk received 1.87 inches of rain; New Canaan, 1.81; Fairfield, 1.42 ; Wilton, 1.28; Tweed-New Haven Airport, 1.26; Madison, 1,14; Milford and Seymour, .95 of an inch; Bridgeport, .91 of an inch; Darien, .83 of an inch; Westport, .82; and Monroe, a half-inch.

The thunderstorms, trigged by a cold front, dropped temperatures nearly 20 degrees over in a three-hour period. Sikorsky Memorial Airport’s high temperature was 92 degrees just before 3 p.m.; by 6 p.m., the temperature was 73.

The NWS said “a frontal boundary will remain south of Long Island through the weekend. A few weak disturbances will track through the area today and tonight producing some light rain.

“It will be noticeably cooler with a good deal of clouds as temperatures will return to more seasonable levels. Canadian high pressure will build towards the Northeast through Saturday night with mainly dry conditions expected. Temperatureswill average near normal on Saturday with highs in the lower and middle 70s.”

After that, there’s a big question of what track Tropical Storm Florence will take over the next serveral days.

The storm is located more than 900 miles east of Bermuda, and forecasters said it was too early to say what, if any, hazards it may bring to the U.S. coast.

Computer track models so far disagree on a future track, raising uncertainty about its path next week.

However, they still expect Florence to remain a dangerous hurricane and said it’s likely to regain intensity as it churns west.

At 5 a.m. Friday, the National Hurricane Center said Florence had weakend with winds down to 65 mph, The NHC expects it to strengthen over the weekend.

As the season reaches its peak, two other systems off the African coast also continued to look more likely to become tropical depressions.
