Warmer air will pour across the Northeast for Memorial Day but will not have staying power with yet another fresh shot of cooler air to follow.
The unofficial start to summer will be a warm one for most of the Northeast on Memorial Day.
Temperatures will rise into the 80s throughout the mid-Atlantic and northward to Albany, New York, Boston and the rest of central New England.
The good news is that the holiday will not be an oppressive one for outdoor celebrations, picnics and parades since humidity will remain low.
For those planning to spend a part of the holiday swimming, remember that cold water shock is a threat for anyone jumping into the ocean, lakes and unheated pools.
Since Monday will also feature partly to mostly sunny conditions, be sure to take preventive measures against the sun's harmful ultraviolet rays.
Only across northern New England--and southward to Boston--will showers and thunderstorms threaten to ruin holiday festivities. Across northern Maine, the wet weather and accompanying clouds will hold temperatures to the 60s.

The storm delivering the showers and thunderstorms will be responsible for preventing a lengthy taste of summer for the Northeast.
Temperatures will take a tumble across more of New England and the St. Lawrence Valley on Tuesday. However, the warmth is likely to hold for one more day in Bridgeport, Connecticut, and the rest of southwestern New England.
Air conditioners and fans will be in high gear across the mid-Atlantic on Tuesday as temperatures once again soar into the 80s and humidity increases.
Tuesday's steamy air may also set the stage for locally drenching and gusty thunderstorms to erupt and ruin plans to beat the heat by taking a dip in a pool or lake.
To keep cool on Wednesday, all residents of New York City and Poughkeepsie, New York, Philadelphia, Trenton, New Jersey, Wilmington, Delaware, Scranton and Harrisburg, Pennsylvania, will have to do is open the windows and let cooler and less humid air filter in.
Baltimore and Washington, D.C., should also welcome a reduction in the heat on Wednesday.
The magnitude of cooling for Pittsburgh and the rest of the upper Ohio Valley and eastern Great Lakes at midweek will depend on how the cooler air advances into the Northeast.
The steamy air would be able to hang on a bit longer if the cooler air arrives via the passage of a backdoor cold front and makes more southward progress east of the central Appalachians than points to the west.
A stronger cold front will have more success in pulling cooler air down from the northwest and into Pittsburgh and surrounding areas.
