It, somewhat unexpectedly, turned into a rainy day with temperatures holding in the 70s (rainfall amounts generally 0.1-0.4 inches). But the payoff is eventual clearing tonight and an absolutely wonderful weekend weatherwise. Both days are sunny and warm, with low-moderate humidity.
Through Tonight: Showers may linger through around sunset, mainly east of the District. Then skies slowly clear, with drier air working in as the night wears on. Lows range from the low-mid 60s downtown to the upper 50s in the cooler suburbs. Winds are light.
The weekend: About as good as it gets – both days. Skies are mostly sunny, humidity is agreeably low (dew points 55-60), and temperatures are just about perfect with highs in the low 80s. Winds are light from the north – at around 5-10 mph. Saturday night is mostly clear with lows in the 50s to around 60 downtown.
Pollen: Before the rain, which presumably washed the pollen away, counts were low for grasses and trees, moderate-high for weeds and low-moderate for mold.
Rim Fire in California: A massive wildfire has blossomed in central California and has spread into Yosemite National Park. The fire, which has charred 105,000 acres this week, is forcing evacuations in the area. NASA captured the view of the blaze from space below.
