A Fall-Like Start to Labor Day Weekend, Some Light Rain on Sunday

September 3, 2021 // Article by: Jen D’Iorio

A pleasant and likely dry Friday is expected across the Northeast and Mid-Atlantic, with a fall-like feel in the air. Expect high temperatures in the upper 60s to low 70s farther north, and in the mid-to-upper 70s (perhaps low 80s) farthest south. These air temperatures, combined with low humidity, will be perfect for any outdoor plans you may have to kick off the holiday weekend. Any lingering flooding of streams, creeks, and rivers due to Ida's remnants will continue to recede today and tomorrow as well, allowing our region to recover from the excessive rainfall that fell on Wednesday.

Friday night remains quiet under a starry sky as high pressure continues to have a hold over the region. Another cool night is expected, with temperatures primarily in the 50s (slightly warmer along the coastline, slightly cooler in higher elevations/places far inland). High pressure dominantes the Northeast and Mid-Atlantic on Saturday as well, leading to another pleasant day with abundant sunshine, low humidity, and temperatures mainly in the 70s. Take a look at the Hi-Res NAM model for 4 PM tomorrow, no precipitation in sight!

While Saturday night starts off mainly clear, clouds begin to build across the region in the predawn due to an approaching disturbance. A few showers may even be able to make it into northeastern PA, northwestern NJ, and the Hudson Valley by sunrise on Sunday with this disturbance on our doorstep. Scattered showers will then build from west to east across the Northeast and Mid-Atlantic through the morning and afternoon on Sunday. Thankfully, precipitation is expected to be sporadic and on the lighter side, and is not expected to cause additional flooding issues. The best shot for some dry time in the Mid-Atlantic looks to be towards midday and through mid-afternoon, in between two "waves" of potential showers. Meanwhile, the best time for dry conditions looks to be in the early-to-mid morning across New England before showers arrive from the west later in the morning and through the afternoon. Temperatures are largely expected to peaks in the 70s again, though Maryland and northern VA may reach the low-to-mid 80s.

This disturbance will exit the region on Labor Day, leaving behind a primarily dry and slightly warmer holiday across the Mid-Atlantic under mixed sun and clouds. In New England, a few showers may linger as the system departs, tapering from west to east as the morning and afternoon progress. Temperatures on Labor Day return to being more seasonable, mainly in the low-to-mid 80s.

High pressure and dry weather then resumes on Tuesday under lots of sunshine, with temperatures across the Northeast and Mid-Atlantic in the upper 70s to low 80s. Check back here on Tuesday for an update on this next week's weather. Have a great holiday weekend everyone, stay safe!
