    Since it's quite severe-wise here, I recommend checking out the setup for Wednesday in the Pacific Northwest. Great shear with the intense approaching trough and surprising amounts of instability.

    I know that this is somewhat tongue-in-cheek, but all 3 of those forecasts agree on a very cold air mass to our north and a very warm one to our south. They simply disagree on the location of the boundary. That's really not unusual in any way for a 7 day forecast in spring, even if the difference in sensible weather impacts is massive if you move from one side of the front to the other. And the disagreement is less if one examines the ensembles.

    Yeah, very close call for southern and eastern Howard.

    Hi-Res guidance in agreement that heavy showers move southwest to northeast across the east side of DC early this evening. Radar confirms this idea, with thunderstorms now over south-central VA.

    Line filling in nicely now. Was not, however, expecting to be in an MPD..... The wording, though, clearly favors the Eastern Shore.

    It has nicely cooled aloft. This is what I was suggesting earlier that there might be a window for a couple of hours past sunset with a severe threat, as mid-level cooling would compensate for surface cooling. Unfortunately, with the line (or whatever is left of it) not getting into the DC area for a few more hours, I'm just hoping for a rumble or two of thunder at this point.

    Yeah, the initial convection moving up from the southwest really didn't have much of an impact. The line to our west will continue to move east, but we'll be dealing with surface cooling when it arrives. That said, there *may* be a window just after dark when cooling aloft compensates for the cooler surface and allow a severe threat to persist into the DC Metro area.

    The NAM/NAM Nest solution is our path to severe. The HRRR is not. HRRR initiates convection in southern VA by early afternoon which moves NNE and maybe bring a SVR threat to southern MD and the eastern shore, but it screws most of the DC-Baltimore area on severe and rainfall by killing the line arriving from the west. The NAM idea is to have that initial round of convection be far less widespread and not interrupt the convection arriving from the west.

    I don’t hate the end of the 12z NAM Nest run…I’ll say that.

    Guidance seems to be converging on better timing for Sunday. Could still be an issue in which widespread clouds and multiple rounds of showers kill instability and any severe threat, but we're in the game for now.

    Spot on. Forecasted highs for Thursday and Friday are way too warm.

    Did you accidentally stumble in here while looking for the Guam forum???
  13. high risk
    Yeah, the GFS timing would be terrible; hug the Euro.

    Beware the midweek back door cold front! A fair amount of guidance has at least the northern parts of the forum much cooler than the far southern parts Wednesday- Friday.

    Thanks for noticing! My forecast was pretty good, except that the storms (while sub-severe) persisted all the way east into the DC Metro area this evening. The CAMs were too quick to really disintegrate the line.
