Before more seasonable air returns, drenching thunderstorms threaten to put a damper on Labor Day outdoor plans in Washington, D.C.
With steamy air in place, a shower or thunderstorm across the Washington, D.C., area are possible on Labor Day ahead of an approaching cold front.
Downpours will accompany some of the thunderstorms, threatening to cause localized flash flooding.
All of the downpours will pose hazards to motorists by reducing visibility and heightening the risk of vehicles hydroplaning at highway speeds. Airline passengers may encounter delays and headaches.
Those with outdoor plans should prepare to move inside for a time or make indoor alternatives.
The good news is that there will still be rain-free intervals on Labor Day.
Residents and visitors should just stay alert for changing weather and seek shelter when storm-related warnings are issued or thunder is heard. For the latter, you are then close enough to get struck by lightning.
While lightning and downpours are the greatest concerns from the thunderstorms through Labor Day, an isolated number producing damaging winds and hail cannot be ruled out.
A shower or thunderstorm will linger into Monday night before the cold front passes through and gives way to lowering humidity Tuesday afternoon.
Several rounds of thunderstorms are on tap for the Minneapolis area over the next few days.
A tropical threat from the Atlantic on the United States and Caribbean islands may increase into next week.

A long-lived and intense thunderstorm dumped hail that ended up being measured in feet in some parts of Mexico City Sunday afternoon and evening.
