With temperatures near 70 and reasonable humidity levels, it was a very comfortable start to our Sunday morning. And while it is becoming quite warm and somewhat sticky, it isn't oppressively so. Look for highs to again reach the mid to upper 80s as they did on Saturday - 86 at Reagan and Dulles, 89 at BWI Marshall - with widely scattered showers possible mostly north and west of the District.
The light winds and relatively stagnant air has prompted the issuance of a Code Orange Air Quality alert. People with respiratory problems are advised to limit exertion outdoors. The sudden onset of summer temperatures and plenty of sunshine also means that its time for everyone to grab the sunblock and hat and to remember to drink more fluids to compensate for increased amounts of perspiration.
Memorial Day could be the hottest of the three-day holiday weekend with highs in the low 90s. Thunderstorms are possible in the afternoon, but the risk is relatively low (30%). The high pressure system responsible for our summery weekend will depart on Tuesday as showers usher in somewhat cooler and drier air for the latter part of the week.
Enjoy the rest of this perfectly-timed taste of summer!
