Raining and sunny

Guessing they are playing it safe with how quickly something could get going but it still seems coverage will be very sparse.

Models don't even show anything besides a few pop up showers that are very isolated. Seems odd to have a watch. 

102 yay

Perhaps the highlands can give the Potomac a drink tonight after all…

Im holding out hope that complex in the Alleghenies does something when it gets here. HRRR didn’t really model what’s happening there now.

IAD has hit 101F. First time since 2012.

It didn’t unless there is something I am missing.

[astarck]

Officially 104, 104, and 101 at the three airports.

Possible that George BM was looking at the IAD ASOS live page. Might have gone up and then back down.

Do you have a link to that?

I’ll await for confirmation from NWS. They will send out a climate report soon.

It going to eat Romney.

Yeap. Everything Kmlwx said. That's my go to link for weather obs at IAD.

That walk from my office on 1st Street to Union Station earlier was like being in a furnace!  It was just like that day in June 2012 when we hit 104/105.

I am salivating at this pattern change coming with a decent stretch of maybe not even reaching 90.  I do not expect any rain tomorrow but that's OK

Cell #3 trying to give it a shot

Holding out hope for the next couple of hours.

“Further to the southwest into MD and VA, convection has largely struggled to remain sustained over the past hour - likely due to generally weak forcing for ascent driven mainly by diurnal heating and some lift along a diffuse lee trough axis. However, early signs of convective development has been recently along an outflow boundary associated with upstream convection across WV. Deeper convection may materialize east of the Appalachians as the boundary moves into a more buoyant air mass. Very warm surface conditions (temperatures in the upper 90s, low 100s) are resulting in deep boundary-layer mixing up to 2 km, which, when combined with PWAT values around 1.75 inch, should be supportive of wet downbursts with an attendant severe/damaging wind risk. Convective coverage remains uncertain, but recent WoFS guidance continues to show at least scattered thunderstorm development, suggesting the wind risk continues across southern portions of WW 548.”

Didn't amount to much out my way...0.17" but did drop the temp into the upper 60s which was obviously nice. Hope it gains some more juice as it heads east.

[pazzo83]

DCA stayed at 100F or more from 1250pm to 545pm - insane.

Derecho day was still 103 at 6pm, but caught a river wind and dropped to 96 at 7pm.  Bounced back to 98 at 8pm.

Even up in the catoctins above 1200ft it was 95+ today.

That doesn't happen often.

Heh, because of the derecho, the low temp on 6.29.12 was just one degree warmer than normal.

[dailylurker]

I'm standing on Bacon Ridge in Crownsville. I'm looking west and have been watching a lot of new towers going up. It's beautiful with the sun setting. It's extremely dry, humid, and hot. It's still probably 93.

What was the dewpoint? I remember walking out of my shop just before it hit and the air was so thick you could cut it with a knife.
