Despite considerable clouds, we still logged yet another day at or above 90-degrees. Unfortunately for those in need of rain - most of us - showers and thunderstorms have been widely scattered. Storms gradually subside this evening marking the transition to drier and eventually cooler conditions.
Through Tonight: There’s a mere 20-30% of evening storms - which should wind down by between 6 and 10 p.m. from northwest to southeast. Then skies slowly clear - possibly opening up a window for Perseid meteor shower viewing pre-dawn. Lows range from the mid-60s in the cooler suburbs to the low 70s downtown.
Tomorrow (Wednesday): We have wall to wall sunshine which, despite the steady arrival of drier air, boosts afternoon temperatures back into the low 90s. Winds from the west around 10-15 mph will be pleasant. Humidity levels may still feel a little sticky in the morning but should feel much better by evening.
