High pressure will settle over the region on Sunday, providing dry conditions with lighter winds than Saturday as the pressure gradient weakens. It will be cooler before it gets warmer as a backdoor cold front will pass through Sunday night. Daytime highs will be in the upper 50s to low 60s and Sunday night will be colder, especially for interior and rural areas, with lows from around 30 degrees across the higher elevations and around 40 degrees across the CT shoreline.

 

Looking ahead, the upcoming week will continue to be unseasonably warm and dry. Monday will be the coolest day of the work week, with highs in the mid to upper 50s. By Tuesday, high pressure shifts offshore, and warm air will move in from the southwest, pushing temperatures higher. Wednesday and Thursday are expected to be particularly warm, with highs reaching the mid-70s across most areas and possibly near 80°F across the CT River Valley, setting up a potentially record-breaking warm Halloween.

While dry weather remains dominant, the threat of rapid fire spread should decrease slightly early in the week due to increased humidity. The next chance of rain may come with a cold front on Friday, but there is still uncertainty about widespread rainfall. Right now, at least scattered showers are expected throughout Southern New England. Models are hinting at a more soaking rainfall 8 to 10 days out, but a lot can change at this forecast range.
