PM Update: Brief Heat Begins Retreat
Mostly sunny and beautiful on Wednesday
Today is day 27 of 90 degrees or higher at National Airport this year, the second such day in a row, and probably the last for a while. A wind from the northwest has brought dewpoints down a notch from yesterday, so while it's hot, it's not too humid. This afternoon and evening will be great for outdoor activities as temperatures fall back from highs in the low 90s through the 80s prior to sunset.
Tonight: Following the passage of a cold front, tonight will be cooler and humidity levels will fall some more. Skies will be mostly clear and temperatures should drop to around 60 in the suburbs and into the mid 60s for the District. A wind from the northeast will occasionally blow around 5 to 10 mph.
Tomorrow: Words like "amazing" or "wonderful" will likely be used to describe Wednesday as temperatures struggle to rise above the low 80s across the area. Combined with little or no noticeable humidity, a light breeze, and mostly sunny skies it will definitely be a day to consider calling in sick.
