Uptick in humidity to lead to return of showers, thunderstorms in Northeast
Following a dry start to the week, higher humidity and the risk of showers and thunderstorms will return to the northeastern United States into Wednesday.
Humidity and warmth will peak across the mid-Atlantic states on Wednesday ahead of the system, but will remain a bit lower than levels experienced previously in the summer.
Higher humidity will reach New England by Wednesday evening.
Highs in most areas on Wednesday will be in the 80s. While AccuWeather RealFeel® Temperatures will be higher than the actual temperature, cloud cover will generally limit the increase to a few degrees.
Showers and thunderstorms will end across western Pennsylvania and New York early on Wednesday then track eastward toward the Interstate-95 corridor through the afternoon and evening.
While widespread severe weather is not expected, a few of the storms can be heavy and gusty.
However, it may take until Wednesday night for rain to reach New England as well as the lower mid-Atlantic coast.
Moisture from Tropical Storm Erin is forecast to be pulled northward into eastern New England late Wednesday and Wednesday night. Enough rain can fall to cause areas of flooding, especially in low-lying and poor drainage areas, including in Boston and Portland, Maine.
"While the humidity will return and last through Wednesday, this change in the pattern will be short-lived," according to AccuWeather Meteorologist Alyson Hoegg.
"Fall-like weather will return soon," Hoegg said.
In the wake of the storm system for the middle days of this week, another wedge of dry air is forecast to move in late this week and into the first part of the Labor Day weekend.
