The heat is the big story of the day with Reagan National tying a record high and hitting its hottest day so far this year. A few storms are possible this afternoon and evening but they should diminish after sunset. Tonight will be partly cloudy, warm and muggy with lows in the 70s.

Wednesday is expected to be the hottest day of the work week with highs in the mid to upper 90s and heat index values approaching 100 degrees. With ample moisture and instability, a few storms will again be possible in the afternoon and evening.

Storm chances increase Thursday as a frontal boundary slides in from the north. Highs should reach the lower 90s and storms are expected later in the day. Temperatures will fall back into the 80s Friday into the weekend, but daily storm chances will remain with Saturday being the most likely day for widespread afternoon storms.
