Monday Insights: Historic Connecticut Rain Review; Preview of the Week Ahead

Today’s “deep dive” into meteorology we offer goes a bit off-script: usually we only look ahead, but the rain in Southwest Connecticut on Sunday, August 18, was historic and deserves a recap, so Matt Noyes provides that here.  Then, Matt takes us to the jet stream level, where a new “upper level low” is diving into the Northeast. Matt also shares our New England 14-day forecast and 14-day dew point forecast – it’s all in the video!

A Look Back at Connecticut’s Epic Rainfall On Sunday, parts of southwest Connecticut experienced a historic rainfall event, with some areas seeing around a foot of rain. This led to significant flooding, road washouts, and even water rescues. If you’re interested in a detailed analysis of how this extreme weather came together, be sure to check out our video posted above.

Looking Ahead: The Week’s Weather Highlights

• Tuesday Break: After today’s lingering showers, downpours and thunder with isolated flash flooding and severe storms (see our 1°Outside Today video for more), most of us will see a break in the action tomorrow. Expect cooler temperatures with a northerly wind keeping highs in the 60s to low 70s. It’s a day to enjoy the pause in the unsettled weather before things pick up again midweek.
• Midweek Showers & Thunderstorms: Wednesday brings a return to more active weather with scattered showers and thunderstorms as a new jet stream disturbance moves in. These won’t be as widespread as Sunday or today’s rain, but they will crop up.
• Late-Week Improvement: By Thursday and Friday, drier air begins to take over. Although a few isolated showers may pop up, the overall trend is toward clearing skies and slightly warmer temperatures. Highs will climb back up near 80 by Friday, making for a more pleasant end to the week.

Ernesto’s Impact & Ocean Conditions While Hurricane Ernesto continues its path well southeast of Newfoundland, its effects on our region are diminishing. Rip currents and elevated seas will continue today, but waves will gradually decrease as we move deeper into the week, bringing calmer conditions by midweek.

Cool Nights Ahead With the arrival of this new air mass, expect some chilly nights – parts of eastern New York and northwestern New England could dip into the 40s—a reminder that fall is not too far away!

For those tracking the weather closely, you can always use our interactive radar on the Noyes’ 1Degree Outside Weather app, available on the App Store and Google Play. Keep an eye on the dew points too, which will drop through the week before climbing again as we head into next week’s warmer weather.
