* 90+ days so far in 2010: 50; Next up to pass, 1993 & 1881 (51 days) *
The official numbers are in and they show that National Airport hit 98 a little before 3 p.m. today, tying the previous record high for the date. With 50 days of 90 degrees or higher now behind us, this is the earliest we've hit such a mark in recorded history. Temperatures that reached highs in the mid-and-upper 90s were thankfully not accompanied by the highest humidity levels we see around here. The good news is that unlike some of our previous heat waves, this one does not have major staying power.
Mostly clear and warm 8:15 update: Partly to mostly cloudy and warm with a few scattered showers possible through about 10 or 11 p.m if they hold together. After that, skies should clear back out. Evening readings that drop to near 90 around sunset ultimately fall to lows in the lower 70s in the cooler spots to the upper 70s in the warmest ones.
Tomorrow (Wednesday): We'll see some more in the way of clouds tomorrow, but partly sunny skies should still help highs rise to at least the mid-90s across the area -- a few upper 90s in and near the city centers can't be ruled out. Heat indices again rise to near 100. Clouds should increase late, especially heading into the night.
Tropics: An area of disturbed weather just west of the Florida peninsula is being monitored by the National Hurricane Center. Conditions are expected to become more favorable for tropical development over the next day or so as it drifts in the general direction of Louisiana, but expectations are not terribly high at this point. Weather Underground's Jeff Masters discusses the system in more depth on his blog. 7:30 Update: This system has become a tropical depression and tropical storm warnings have been issued for portions of the northern Gulf.
