Temperature Map

Temperatures: Latest D.C. area temperature map. See interactive map on our Weather Wall.

In some areas today clouds held obstinately, in other areas the sun broke through. Depending where you were, high temperatures ranged from the mid-60s to mid-70s. It’s relatively mild and tranquil overnight before wild Wednesday commences. We start the day with spring-like warmth, then deal with storms – which may be strong to severe – before temperatures crash and winds whip into a frenzy.

Through Tonight: Cloudy and mild with a soft breeze from the south. Lows range from the upper 40s to low 50s (downtown).

Tomorrow (Wednesday): Variably cloudy and warm through the early-to-mid afternoon, with temperatures rising to around 70. The chance for showers and storms increases from mid-afternoon onwards, with the best chance in the late afternoon and early evening. Some of these storms may be strong to severe with damaging winds and even an isolated tornado. Stay weather aware tomorrow as watches/warnings may be issued. Following the passage of the cold front in the evening, winds crank with possible gusts in the 40-50 mph range and temperatures fall through the 30s late in the evening and overnight.

Alaska Iditarod sled dog race plagued by lack of snow: The Last Frontier’s storied Iditarod sled race is dealing with an unusual problem this year: Bare ground. Writes the LA Times:

The Iditarod weather is similar to the kind of situation displayed in the Winter Olympic Games in Sochi, where unseasonable warmth threatened to undermine national pride. Russian organizers ended up carting in snow.

Over the weekend, workers in Nome, Alaska, took a page out of the Sochi playbook and trucked in snow for the big finish.
