Mugginess to Return After Short Respite

Now

Hot, but less humid. A bubble of drier air to the north of a "cold" front slid into the Mid Atlantic area overnight, bringing considerably more comfortable humidity (dewpoints 10-15° lower than yesterday) to the area, despite temperatures generally in the low 90s. By 5pm, National had reached at least 92°, and Dulles was 93°. As that front moves back northward, mugginess and the chance of thunderstorms will increase before a significant cooldown arrives for the weekend.

Tonight and Tomorrow

Increasing humidity, chance of showers. Comfortably warm and clear conditions this evening will lead to lows overnight in the low 70s downtown and the mid to upper 60s in the 'burbs. Mugginess will increase tomorrow, along with the chance (40%) of showers or thunderstorms late in the day. Highs tomorrow will be 89-92°.
