Those looking to celebrate summer's last hoorah this weekend may want to plan carefully, as numerous storms across the Midwest and East could hamper plans and slow traffic on heavily traveled routes to beaches and cities.
More than 34 million people will travel for Labor Day, marking the most significant numbers for the holiday since the recession-driven decline, according to AAA Travel.
Forty-six percent of travelers were expected to depart on Friday, the company said, threatening clogged roadways and extensive delays to enter popular tourist destinations.
Numerous holiday-tailored events are scheduled to kick off Saturday, unofficially ending the summer season in Washington, D.C., and Philadelphia.
Warm and humid conditions will deliver a mixture of clouds and sun and a thunderstorm risk in the nation's capital, where visitors and locals will gather to celebrate the annual Blues Festival in Rock Creek Park.
The same potential will greet Philadelphia concert-goers in attendance of the Labor Day weekend outdoor 'Made In America' music festival.
The troubles won't stop Sunday and Monday as travelers wrap up the holiday weekend and head home.
Early-morning fog could hover over roadways that received rain the previous night, slowing speeds on major routes. The evening hours Sunday through Monday will usher in more storms, likely becoming the wettest period of the weekend for the I-95 corridor and the Appalachians.
Another visit from the Polar Vortex will deliver unseasonably cool air to the Midwest, preceded by rounds of thunderstorms, including severe weather.
Welcome dry weather for cleanup efforts across Japan in the wake of Neoguri will be brief.
As the Northeast continues to clean up from destructive storms early this week, more rounds of severe weather loom for early next week.
Heat-related dangers will be on the rise over the weekend for much of the Northwest as scorching heat settles in.
San Francisco will see a rise in temperatures over the next several days as partially cloudy skies make way for plenty of sunshine.
Days after Neoguri takes a curved path over Japan and into the northern Pacific, much cooler air will drive southeastward across the Midwest and into the Northeast.

A bolt of lightning at the Picatinny Army Arsenal in Northern NJ triggered a massive explosion in an ammunition dump. Every building within a half mile was leveled by the blast and 16 people were killed. Debris landed as far as 22 miles away and over 100 million present-day dollars of damage was done. This is the most costly damage due to lightning in the United States.
