Tuesday Looks Delightful in New England, But It's Not the Best Day of the Week

NBC Universal, Inc.

Parts of southern New England picked up close to one inch of rain last night. That steady rain and its low pressure center are now well offshore, but plenty of residual moisture and instability in the atmosphere are left behind.

Under a mix of clouds and few sunny breaks, temperatures were hard-pressed to rise out of the 50s for most of southern New England and lower 60s north on Monday.

A stronger upper-level disturbance, cool pool aloft, Monday night will deliver a period of late evening and overnight rain from west to east across northern New England with a passing shower or sprinkle around or just after midnight farther south, leading to a drying westerly wind that will start clearing skies for sunrise Tuesday. 

Tuesday looks delightful for most of New England – fair sky and a fresh breeze with westerly winds gusting to 30 mph at times, while the fair-weather clouds in northern New England likely will build tall enough for some new scattered showers in the hills and mountains during Tuesday afternoon. 

With climate change, global temperatures are going up, but starting this week it won't sound like it's as hot as before.

New England remains under a jet stream “trough” through midweek – keep in mind the jet stream is the fast-flowing river of air, high in the sky, that steers disturbances and storms and separates cool air to the north from warmer air to the south, and a trough is when the jet stream dips to the south, encouraging disturbances and cooler air to move through. 

Wednesday afternoon will feature another disturbance dropping over New England in this trough, meaning sunshine will likely yield to increasing clouds with some scattered showers developing during the afternoon. 

Behind Wednesday’s disturbance, the best day of the week arrives Thursday: sunshine and 65- to 70-degree high temperatures in the afternoon. 

Friday won’t be far off from Thursday’s splendor, though clouds will increase ahead of a chance of rain Friday night. 

A nearby and nearly stalled frontal boundary – the battling edge of cool and warm air – will be relatively close to New England this weekend, with storm centers likely developing to our south along that front, meaning some scattered showers are possible both weekend days, though neither appears to be a washout right now, and the chance of showers very well may decrease as we get closer to the weekend if showers end up consolidated closer to the front. 

At this point, it looks like we warm slowly but surely into next week at the end of our exclusive First Alert 10-Day forecast.
