Will you be able to enjoy one last weekend of summer or will fall be taking over Labor Day weekend?
If you live in the Northeast or Midwest, it will definitely feel more like the dog days of mid-summer than September. This is due to a large area of high pressure that will be centered over the eastern half of the U.S. through this holiday weekend.
However, if you are in the Northwest or the northern Rockies you are in store for a fall preview as an upper-level trough will be moving through this weekend.
A few severe thunderstorms are also possible along a slow moving cold front in portions of the Plains and Midwest, while pesky afternoon thunderstorms may soak parts of the Southeast.

Saturday
Saturday's Forecast
High pressure will dominate much of the East bringing warm and sunny conditions. If you are heading to the beaches from New England to the Mid-Atlantic one last time, dry and warm conditions are expected Saturday and through the holiday. However, scattered, slow-moving thunderstorms are expected to develop in the Southeast and along the Gulf Coast, particularly during the afternoon and early evening.
High temperatures up to 15 degrees above average will be found in the Midwest and interior Northeast, with some of those areas flirting with 90 degrees.
A cold front stretching from western Ontario into the northern Plains will enhance the risk of thunderstorms in the region, with a few storms reaching severe criteria. Showers will also be found through much of the Northwest due to the influence of the upper-level trough. Meanwhile, snow is even possible in the highest elevations of Idaho, Montana and northwestern Wyoming on Saturday night.
Thunderstorms will also develop in parts of the Four Corners region, enhanced somewhat from moisture courtesy of Tropical Storm Kevin. Meanwhile, further west across much of California and the coastal Northwest, sunshine and dry conditions should prevail.
High temperatures will range from the 50s to the 70s for much of the Northwest, which is up to 20 degrees below average for this time of year.

Sunday
Sunday's Forecast
The cold front in the central U.S. will move slowly eastward, bringing the chance for thunderstorms, a few of which may be severe, across the Upper Midwest. Showers will also linger on the backside of the area of low pressure in the northern Plains and northern Rockies. Some snow is not out of the question in the highest terrain.
Chilly conditions will persist in much of the Northwest and the northern Rockies. Temperatures to start the day will be in the 30s and 40s for much of the region and will recover into the 60s and 70s. The Southwest, meanwhile, is in store for a mainly dry day with hot temperatures in the interior and typically cooler highs are expected towards the coast. A few t-storms cannot be ruled out in parts of Arizona and New Mexico, however.
If you liked the weather on Saturday in the Northeast then Sunday will be a winner as well. Most of the Northeast will see a warm and dry day. The best chance for scattered showers and thunderstorms in the East will continue to be found in the Southeast and along the Gulf Coast.
Summerlike temperatures will continue to hang on in the Midwest and Northeast with highs in the 80s and 90s. Expect more heat, with some highs approaching 100 degrees, in the southern Plains. Temperatures will be closer to average in the Southeast.

Labor Day (Monday)
Labor Day Forecast
High pressure will once again influence weather conditions in the Northeast, with another sunny and hot day on tap, making it a trifecta for the extended holiday weekend.
Cooler temperatures will begin to move into the Midwest as the cold front mentioned above continues to press eastward. Scattered showers and thunderstorms will accompany this system from the central Plains, northeastward into the Midwest and Great Lakes.
Outdoor picnics and barbecues across the Gulf Coast and into the Carolinas will need to be prepared for scattered drenching thunderstorms. Highs around much of the South will reach the 80s and 90s.
Most of the West will see improving conditions as high pressure moves in bringing a dry end to the Labor Day weekend. The exception will be areas near the Canadian border, where a few showers are still possible, and the Desert Southwest, where afternoon and evening t-storms could flare up. The West Coast will see mostly sunny skies and temperatures will be a touch warmer, inching toward seasonable levels.
