Northeastern US: Building heat into midweek to precede downpours fueled by Barry

After temperatures throttled up on Tuesday, highs in the 90s will engulf nearly the entire Interstate-95 corridor on Wednesday.
Similar highs will bake Allentown and Harrisburg, Pennsylvania, and Charlottesville, Virginia, at midweek.
When humidity is factored in, AccuWeather RealFeel® Temperatures will soar between 95 and 105 these days.
Residents will want to be sure to drink plenty of water, wear light clothing and take frequent breaks if strenuous activities cannot be avoided during the midday and afternoon hours to avoid suffering from heat-related illnesses.

Taking a dip in your community's local swimming pool or heading to the beach is another great way to beat the heat, but be wary of thunderstorms that will erupt.
East of the Appalachian Mountains, spotty thunderstorms will ignite in the afternoon with more numerous showers and thunderstorms to follow at night and into Thursday as Barry's moisture surges eastward.
"Given how much moisture will be in place, there is the potential for heavy rainfall with any showers or thunderstorms that do develop," according to AccuWeather Meteorologist Randy Adkins.
"Fortunately, downpours should be moving along rather briskly, so the threat for widespread flash flooding is low," he added.
A few issues can develop in low-lying and urban areas. Travelers, meanwhile, may encounter minor delays.
"Non-flooding downpours may not be a bad thing in areas where lawns are turning brown and gardens and crops are being stressed by hot weather and dry soil conditions that occasionally develop in July," according to AccuWeather Senior Meteorologist Alex Sosnowski.
While actual temperatures will be trimmed slightly as the downpours swing through, residents will not be treated to a reduction in the sweltering humidity. That will be the case even after the wet weather departs.
Instead, the door will swing wide open for more heat and high AccuWeather RealFeel® Temperatures to engulf the Northeast to end the week.
AccuWeather meteorologists will be closely monitoring the threat for clusters of severe thunderstorms to erupt along the rim of this heat in the Upper Midwest and dive into a part of the Northeast.
