CommuteCast: Return of the 90s
More hot and humid conditions Friday
Right on cue, the heat and humidity of summer has returned to the area today. Morning cloudiness has given way to increasing (though hazy) sunshine, and temperatures have responded by rising up past the 90-degree mark (for the sixth time at National Airport this season). Isolated thunderstorms are possible for the rest of the day, some of which may contain gusty winds and/or small hail.
Tonight: After a risk of isolated evening thunderstorms, skies will trend toward mostly clear. Humidity is back so temperatures won't fall too much tonight. Expect sticky lows in the mid 70s for the city to right around 70 in the suburbs.
Tomorrow: Friday looks to be nearly a carbon copy of today with partly cloudy skies and temperatures rising into the low and mid 90s. In addition to the heat and humidity, isolated afternoon or evening thunderstorms will be possible once again.

There's some sort of boundary (stretched east-west) sitting (or slowly drifting north) right over DC currently, can be seen on both doppler loops and satellite loops. It's getting a bit late to expect thunderstorm initiation when there is nothing else of consequence in the area, but there has been a bit of vertical growth to the clouds over the last half hour.

Ian, that is an odd boundary. You can't see it on radar anymore, but you can clearly see it on GOES IR Satelite.

It is somewhat odd, Havoc, though it could be a remnant of storminess that passed north of here this morning? It's close to stationary overhead here in upper NW. To the south it's very clear, to the north it's very clear. Overhead there are some darkening clouds, most without much height to them. Off to the west though there are some growing towering cumulus.

Looks like Sterling NWS was watching it too:
Nowcast as of 6:23 PM EDT on June 26, 2008: At 620 PM...National Weather Service Doppler radar indicated an outflow boundary extending from eastern Fairfax County east through Anne Arundel County and into the mid Chesapeake Bay. The outflow boundary was moving north at 25 mph. The outflow boundary will cause a change in wind direction from west to south southwest...and may lead to brief wind gusts up to 30 mph.

Sounds much like last weekend's forecast, though the general storminess predicted a week ago for last Sunday never showed up in my neighborhood. Perhaps that will happen again this week.
