Summer Weather Forecast For Connecticut: See Daily Prediction

CONNECTICUT — With the official start of summer just weeks away, planning has begun for the residents of Connecticut who look forward to the warmer weather and increased opportunity for outdoor fun.

Specific, long-term weather predictions can help with that planning, and the private weather company AccuWeather has released its 2021 summer weather forecast.

Daily forecasts for Connecticut are listed until early August. After that, AccuWeather lists the historical average temperature for the rest of the summer.

The big takeaway for Nutmeg State residents is the total absence of any days with temperatures 90 degrees or higher. AccuWeather forecasters predict comfortable and mostly dry days all summer longer, from Greenwich to Pomfret. June is shaping up to be the wettest month of the summer, but nothing looks like a vacation-wrecker until the third weekend of July. Then, AccuWeather meteorologists predict storm activity for for straight days, beginning Thursday, July 22.

Regionally, the first part of the summer will feature frequent thunderstorms across the Northeast, limiting the potential for long-duration heat waves with temperatures averaging right around normal.

Those July thunderstorms, while disruptive, will be beneficial for some areas of the Northeast where pockets of moderate drought have sprung up in recent months, according to the U.S. Drought Monitor, and were affecting parts of these regions as of late April.

AccuWeather's long-range forecasters believe that several rounds of stronger storms could sweep across the region, particularly in June and July, in addition to garden variety summer storms that pop up on warm and humid afternoons.

Nationally, AccuWeather predicts an eventful summer similar to the 2020 season, which brought record-breaking deaths and damage in the form of wildfires and hurricanes.

Meteorologists are also expecting the return of derechos, a weather phenomenon sometimes referred to as an "inland hurricane." The term became more widely known about last summer when one swept through Iowa with winds faster than 100 miles per hour on Aug. 10.

"We are still very nervous about the possibility of derechos developing based on the pattern that we’re forecasting" Paul Pastelok, AccuWeather's chief long-range forecaster, said in a statement.

This year, the most extreme weather is expected in the early fall, Pastelok added.

Although the number of tropical storms is predicted to be down from recent years, AccuWeather says tornadoes are likely to be on the rise from May until July.

Pastelok said anywhere from 1,300 to 1,400 tornadoes could be reported by the end of the year, a slight increase from 2020.

"Across the Plains, we’re still going to be watching for the possibility of a flare-up of storms, mainly central areas on north during the month of May, June and early July," Pastelok said in a statement.

These storms are expected to extend farther east than normal, Pastelok added, due to drought conditions that range from Montana to the Texas Panhandle.
