A very hot and humid airmass will hold in place today over the D.C. area, allowing the region to possibly have its first 90 degree day of the year. If you remember last year we tied the record for 90 degree days in a calendar year in D.C. at 67. Also, the first 90 degree day last year occurred on April 6th, though at this time last year, we only had 3 90 degree days, so catching up will be easy, and something easily obtainable over the next week.
A few thunderstorms may accompany the heat and humidity later this afternoon with the best chance west of town towards the mountains. Closer to D.C., our area has a strong temperature inversion overhead which should keep the D.C. Metro capped from thunderstorm development. Tonight will be partly cloudy and muggy with lows in the 60s. A much better chance for storms will exist Friday as the cold front finally makes it to the region.
For the Memorial Day weekend, it should continue to be hot and humid with highs in the upper 80s Saturday and Sunday and in the lower 90s by Monday. There is a slight chance for storms on Saturday, but otherwise expect mostly sunny skies.
