While a shower or thunderstorm will return to Washington, D.C., to end the weekend, downpours may arrive by Tuesday.
It is hard to top Saturday's weather, which featured low humidity, sunshine and a lack of rain and heat.
Sunday will definitely prove to be not as perfect as Saturday was for anyone who wants to spend time outside. A cold front dropping down from the north will cause a shower or thunderstorm to be around from the midday on.
The good news is that Sunday will be far from a washout, but the showers and thunderstorms still threaten to briefly interfere with outdoor plans and sporting events.
One such event is the baseball game between the Nationals and the Pittsburgh Pirates at Nationals Park later Sunday.
Otherwise on Sunday, residents and visitors will notice an increase in humidity as clouds occasionally block out the sun.
A shower or thunderstorm will linger through Monday before a storm system from the Ohio Valley spreads a band of drenching rain across the mid-Atlantic Monday night through Tuesday.

Even if flooding fails to ensue, the downpours would create hazards to motorists by dramatically reducing visibility and heightening the risk of vehicles hydroplaning at highway speeds.
Additional bouts of showers and thunderstorms will follow for later in the new week. Sweltering summer heat, however, will remain absent but should return later in the month.
