Very warm and humid air will surge back across the mid-Atlantic and Northeast for the first part of the new week, but the sticky air's presence will not last long.
A wedge of high pressure that kept most of the weekend rain-free along the I-95 corridor (as rain grazed the coast) will hold high humidity at bay in New England on Monday.
However, humidity will remain on the rise across the mid-Atlantic and Great Lakes to start the new week. The door will open for the steamy air to spread over the rest of the Northeast Tuesday through Wednesday as the high pressure departs.
It is not just an increase in humidity headed to the Northeast and mid-Atlantic but also soaring temperatures.
Wednesday is shaping up to be the hottest day of the new week with temperatures reaching or cracking the 90-degree mark in Washington, D.C., Baltimore, Philadelphia and Newark, New Jersey.
Albany and Syracuse, New York; Hartford, Connecticut; Boston; Concord, New Hampshire; and Burlington, Vermont, will also heat up to around 90 F.
A nice breeze from the ocean will keep temperatures in check at most beaches.
The combination of the heat and humidity will create hazards and challenges for those who must engage in strenuous labor or those with respiratory issues. Remember to never leave children or pets in your vehicle, even for just a short time.
There will be little, if any, cooling thunderstorms to bring temporary relief each afternoon along the I-95 corridor through Wednesday.
Washington, D.C., and Baltimore have the greatest opportunity of a spotty afternoon thunderstorm sneaking in from the northern and western suburbs. Otherwise, the majority of thunderstorm activity through Tuesday will be confined to the South and Appalachians.
Another round of thunderstorms will dot the South and Appalachians on Wednesday as a cold front threatens the Ohio Valley and eastern Great Lakes with severe thunderstorms in the afternoon and evening. Violent thunderstorms will first target the North Central U.S. early in the week.
The front will mark the leading edge of a fresh shot of cooler and less humid air dropping down from Canada and set to sweep into the Northeast by Friday.
AccuWeather.com meteorologists will be monitoring the potential for severe weather along the I-95 corridor as the front swings through on Thursday.
Latest indications point toward places from Philadelphia and New York City northward escaping severe weather since the timing of the front's passage and peak daytime heating will not align.
The southern mid-Atlantic, Carolinas and Georgia is where the stage may be set for the front to touch off damaging thunderstorms later Thursday.
