Today's Weather Outlook

The first day of autumn will bring mixed weather, including a fall-like feel for the Northwest and Great Lakes, and thunderstorms in the northern Plains and along the Gulf Coast.
WeatherBug Meteorologist Addison Green has the latest in this exclusive WeatherBug National Outlook Video.
Mercifully, the slow-moving cold front teaming up with the remnants of Hurricane Manuel and its abundant moisture will be a distant memory for most in the eastern U.S. to start the workweek. The lone exception will be along the Gulf Coast`s Interstate 10 corridor and in Florida, where umbrellas and rain ponchos will be needed heading back to work and school. Thankfully, it won`t be associated with severe thunderstorms, but a few areas may see flash flooding.
The weekend downpours and elevated touch of humidity will be a thing of the past from New England to the Carolinas and Southeast on Monday, instead replaced by a deep blue sky and plenty of sunshine. It will be anything but summer-like from the Great Lakes into the Northeast and Mid-Atlantic, with 50s and 60s the rule; western Maine may struggle to climb out of the upper 40s on today.
Further south in the Carolinas, Lower Ohio Valley, and Mid-South to Florida, the mercury will climb into the comfortable 70s and 80s; a few spots could eclipse the 90-degree mark in Florida.
The only other weather blemishes across the U.S. will be found with a pair of potent storm systems. The first will roll onto the northern High Plains, some heavy rain and thunderstorms. The other, spinning in the Gulf of Alaska, will trigger a smattering of showers with pockets of steady rain for the Pacific Northwest and northern Rockies.
Those not impacted by these two weather-makers will enjoy plenty of sunshine and a mix between fall and summer temperatures from the central and southern Plains to California.
The Plains, Mississippi Valley, and Southwest will be toasty, with the mercury soaring into the 70s, 80s, and 90s. It will feel like autumn across the Northwest and along the Rocky Mountain spine, where 50s and 60s will be the norm. Even the immediate West Coast along the Interstate 5 corridor will struggle to climb out of the 60s as well.
