Washington is waking to clear skies and temperatures near 59 degrees Tuesday morning, with a sunny afternoon ahead and a high around 80. The calm start will not last forever: summerlike heat builds through Thursday before shower and thunderstorm chances return late in the week.

Sunny Tuesday Starts A Quick Warmup

Tuesday should stay dry and bright, with east winds around 3 to 7 mph and lower humidity making the warmth more manageable. According to the National Weather Service, temperatures rise to about 85 Wednesday and 88 Thursday, while overnight lows move from the upper 50s into the 60s.

Shower Chances Increase With A Cold Front Early Friday

Friday will bring increased shower chances with a cold front early in the day.

Weekend Plans Face A Few Weather Asterisks

Saturday looks calmer and cooler, with partly sunny skies and a high near 81. Sunday rebounds to about 87 degrees, with a more active weather pattern developing into early next week.

The more active weather pattern may extend into early next week. No watches, warnings or advisories are listed for the District, but outdoor plans late Friday through Monday should keep an eye on the sky.
