It’s been quite a cloudy and muggy day, but for the most part not too rainy. As the remnants of Ana depart to the northeast, the main rain threat from here out is probably associated with showers and storms to the west. They might not make a big impact either. The potential for 90 degrees tomorrow could be the big news of the day, and even better it’s the kind of heat that won’t last long.

Through Tonight: A small risk of sprinkles or light showers, care of Ana, persists mainly east of I-95 the next few hours. Additional activity may move in from the west this evening (40-50% chance). That could bring scattered showers and/or rumbles across the region by the late evening period, particularly over the western half of the area. Any shower or storm could produce heavy rain and dangerous lightning. Lows eventually make the mid-60s to near 70 under partly to mostly cloudy skies. Winds are from the south around 5-10 mph.

Tomorrow (Tuesday): Despite a cold front passing during the day, it’ll be anything but cold! In fact, we might get our first 90-degree day, at least in spots. It appears the front comes through mainly dry, though you can’t ever fully rule out a shower or storm with these things, so let’s keep it at 10-20% chance for the first half of the day for now. With west winds dominating, which is a warming direction off the mountains, we should shoot for highs mainly in the mid-80s to near 90.

90… Already? Maybe. If it happens for D.C. tomorrow, it’s pretty close to when it should be expected based on averages. Looking at just the last 30 years ending 2014, D.C.’s first 90+ day typically comes around May 15. In 2014, our first was on May 13. The latest it’s happened in that 30 years? June 24, back in 2003.
