    The big problem with the GFS forecast now is that we barely see the sun for a week starting 5-6 days out.

    The last winter that fell in that temperature range at DCA was 13-14.

    Actually had to close the windows up again since it popped to 74 and it is still kind of humid out with everything so wet. Looks like there is a second surge of drier air coming this evening.

    2.25”. looks like the big spots were E and W of Frederick this time.

    Big severe warning box south of DC. Guess it makes sense with how quickly these are moving.

    The UHI problem is well-known and accounted for in larger-scale analyses. This summer wasn't super hot, but it shouldn't have been based on where the ridge set up in the west. It is actually kind of sad that we didn't end up below normal. I think the late season humidity also skewed perception of the summer.

    Brief downpours in these tiny cells.

    It is fun to crap on Kirk, but he led game-winning type drives in both games this season, only to see his star RB “fumble” (air quotes because the booth f-d up the review) and his kicker miss.

    Those dew points.

    Got it. "Peak season" was throwing me off.

    Ok, there are too many pages. What are these numbers? Is that a full-year forecast, or a forecast-to-date? What does the () refer to?

    Euro has the frontal passage on Thursday. GFS Wednesday. Go USA!

    Radar totals seem to be matching ground truth. Near 3” in an hour in Annandale inside the Beltway and by Inova Fairfax hospital. Only about a half inch here.

    2007 Mote, T.L., M.C. Lacke, and J.M. Shepherd, 2007: Radar signatures of the urban effect on precipitation distribution: A case study for Atlanta, Georgia. Geophysical Research Letters. 34. L20710, doi:10.1029/2007GL031903. You can probably trace from Marshall Shepherd’s work to get to what is most interesting to you.

    Got the alert for a flash flood emergency.

    Plenty have tried. There are papers about it, but differentiating all the aspects is difficult.

    FF Watch. Looking at radar, I don’t see any way that the UHI over DC didn’t contribute to initiation.

    That's the service you get when you try to gut an essential organization.

    Hard to tell from a still image. "Clear air" echoes can be a variety of things, with bugs probably being the top culprit. The radar wavelength that the NWS radar are at (S-band, 10cm) are also sensitive to Bragg scattering from atmospheric eddies. At times, the radar beam can also be reflected back to the surface (anomalous propagation).

    They seem really loud this year, but I can’t tell whether I’m just hyper-sensitive to them now.

    Larry is going to rack up some ACE.

    I’m guessing there are no new posts on this forum since everyone is outside.

    Great Falls from the VA side this evening. I’ve never visited while the water was up, so this is impressive. Amazing that the flood markers are in a different stratosphere.

    There’s another video out there of a guy walking through ankle deep water and then as soon as he goes to another room, the wall gives out and the whole room immediately floods. In this case he was ok, but that’s the scenario where it can happen very quickly. found it -

    The models did really well. That is an exceptional match, though.
