More sweat-bath weather in D.C. Tuesday; small risk of storms

Ugh. For some people, yesterday might've been a bit too much summer. A big, marble-like slab of antiperspirant to rub against – that would have been a nice household accessory as highs crept up to 86 degrees at Dulles, 83 at National.

D.C. will retain its soupy mouthfeel Tuesday and Wednesday, with temperatures forecasted in the 80s on both days. An enormous stationary front that previously stalled out over Pennsylvania is starting to move north, allowing the Mid-Atlantic to absorb tons of moist, squalid air. If you work hard labor outdoors, today will be a killer; in the office environment, prepare for clammy coworkers and shirts made awkwardly translucent with sweat. “It’ll be a little more humid,” says Doug Hill, ABC7 chief meteorologist. “It won’t take your breath away, but it’s the first real feel of summer.”

As of last evening, the rain predictions among ABC7's weather brain trust ran thus: 30 percent chance of rain Tuesday afternoon, 40 percent Wednesday and 70 percent Thursday. The biggest chance is actually Wednesday night into Thursday as a cold front chatters through D.C. That front is arriving with strong winds that will be conducive for severe thunderstorms, but the nightly timing and resulting lack of heat will work against this storm's big-shot ambitions.

Tired of this up-down-all-around weather pattern, where we're in the 80s one day and the 60s the next and constantly dodging thunderstorms? Well, things usually die down around mid-May, says Hill. That doesn't mean D.C. won't see a day in May when the high is only 60 degrees, he says – just that if it happens, it “would be the lead story” at this here news outlet.

N.B.: If you haven't been following the drastic flooding in the Midwest that's causing evacuations and pumping up the price of grain (barges can't handle the tumescent rivers), I'll be writing more about it tomorrow. But a factoid for now: The National Weather Service reports that Cincinnati might have its wettest April since record-keeping began, in 1835.

N.B. #2: A large tornado reportedly destroyed the town of Vilonia, Ark., last night, ripping pavement off the street and causing at least one fatality, according to preliminary news bulletins. People are guessing it might've been of the most powerful EF-5 variety. Check KUAR for the latest.
