  1. high risk
    I was not expecting to be in a MRGL tomorrow, and most CAMs show no threat to our area at all, *but* there is a scenario in which the MCS that move into upstate NY (and possibly northern New England) late tonight leaves an outflow boundary over northeast PA or central NY, and a new convective complex initiates there and races south-southwest. The idea is best represented by today's 12Z HiResW ARW and to a lesser extent by the HiResW ARW2. It's certainly not likely at this point, and even if it happened, it might die as it arrives, but there is certainly at least some small potential for a surprise event, especially for northeast MD.

    Winds gusted to near severe limits here in southern Howard. The lightning is intense in the trailing stratiform rain.

    The HRRR clobbers most of the area tomorrow, but the other CAMs are more scattered. It's consistent with SPC's concern that the cold front will be well to our west at peak heating, so the storms will have to form on the pre-frontal trough. That scenario can still work well here, but it justifies the hesitation (at least for now) to hold off on upgrading to ENH. Otherwise, I think it would be an ENH setup, and it still might be.
  4. high risk
    Yes, the higher-end severe threat is definitely tomorrow.

    The Day 3 risk for Wednesday is a MRGL for the Eastern Shore and northeast MD, but evening guidance suggests that they will have to move it back tomorrow (as the new Day 2 outlook) to the west to include the DC/Baltimore area. Could even argue for a SLGT, but I'll wait until the 13Z outlook on Wednesday for that to be added.

    WTF is this? (It's just the FV3 doing its "huge storm" thing, but good lord.)
  7. high risk
    We haven't done squall lines well at all in the Mid-Atlantic in recent years, but this setup certainly favors very organized intense convection. Pop-up stuff occurs with weak forcing, and the cold front arriving during peak heating (and it should plenty hot with high dew points) with a modestly strong upper level trough will provide strong forcing.
  8. high risk
    Could be, or it could just be low-level speed convergence which is kind of hinted at on a few HRRR 850 mb images. Regardless, us Howard County folks look to be left out of the show again......

    a number of recent HRRR runs break out an area of heavy precip over north-central and northern Maryland later this evening. It doesn't appear to be a northward propagation of the existing rainfall. Curious to see whether the HRRR is onto something.

    I was more booming my call for a MRGL than excited about severe potential, but I thought we’d do ok with rain this evening. It looks like a miss now, and you’re correct that we will quickly return to drought if this persists.
  11. high risk
    Boom!
  12. high risk
    Sunday might not top 70 over much of the area.
  13. high risk
    Thinking we have a shot at a MRGL on Saturday for a few localized wind events. Lapse rates are lousy, but there will be decent instability and modest deep layer shear.
  14. high risk
    Lots of things obviously need to align, but that's certainly what we want to see if we're hunting derechos. We would be well within the hot, humid air mass, but also just barely within the faster flow aloft, giving organized convective systems the opportunity to race to the east-southeast.

    Experience, for sure. I always look at as much available guidance as I can, and when they don't agree, I make mental notes on which ones did well and which didn't. It's not as tough to keep track of as it sounds. Or you can just cheat and use AI:
