    That seems odd

    Fwiw, Radarscope is tagging max hail of 3.5"

    FDK storm really needs a TW...
  8. yoda
    FDK cell may need a TW soon... 70mph winds and tornado possible tag in it in latest SWS

    Another MCD for C into S VA into NC with STWatch needed soon in it... I guess we will get lumped into that Mesoscale Discussion 1649 NWS Storm Prediction Center Norman OK 1256 PM CDT Sat Jul 18 2026 Areas affected...ortions of southern Virginia...western North Carolina...far northeast Tennessee...southeastern West Virginia Concerning...Severe potential...Watch likely Valid 181756Z - 181900Z Probability of Watch Issuance...80 percent SUMMARY...Scattered to numerous thunderstorms will continue to increase in intensity this afternoon with a risk for damaging wind gusts. Trends are being monitored and a Severe Thunderstorm Watch is likely. DISCUSSION...Thunderstorms continue to develop across the higher terrain of WV, NC and VA at 1755z, and also along a confluence zone extending from northern VA into western NC. Despite weak mid-level lapse rates, diurnal heating of a moist boundary layer has contributed to MLCAPE of 2000 to 3000 J/kg and low-level lapse rates of 8.5 to 9 deg/C. In the presence of minimal CINH, storms should continue to increase in coverage through the afternoon and move generally east. Shear in the cloud-bearing layer will average 20-25 kts across northern portions of the discussion area and 15-20 kts farther south, sufficient for updraft organization and a risk for damaging wind gusts. Trends are being monitored and a Severe Thunderstorm Watch will be needed shortly. ..Bunting/Thompson.. 07/18/2026 ...Please see www.spc.noaa.gov for graphic product...

    Just appeared to in like last 5 minutes if you put radar in motion
  12. yoda
    DPs are in the 75-80 range across the region as temperatures rise into the low 90s
  13. yoda
    Yes, agree. The watch that just came out from them goes into E PA which was a bit surprising to me considering the new watch box for our area would seem to go overtop that... I guess your idea would work. The watch to our north in PA covers like half our MCD lol

    https://www.spc.noaa.gov/products/md/md1648.html Mesoscale Discussion 1648 NWS Storm Prediction Center Norman OK 1150 AM CDT Sat Jul 18 2026 Areas affected...portions of southern Pennsylvania...eastern West Virginia...northern Virginia...much of Maryland...Delaware...southern New Jersey Concerning...Severe potential...Watch likely Valid 181650Z - 181815Z Probability of Watch Issuance...80 percent SUMMARY...Thunderstorms are expected to increase in coverage and intensity through early-mid afternoon. Damaging winds will be the primary concern as storms evolve into eastward-moving clusters and line segments. A watch is likely prior to 18z. DISCUSSION...Strong boundary-layer heating of a very moist air mass is ongoing across the discussion area as of 1645z, contributing to moderate/pockets of strong surface-based instability. Thunderstorms will continue to increase in coverage across the higher terrain, and along a north-south confluence zone across southern PA south into northern VA, during the next few hours. As coverage continues to increase and low-level lapse rates steepen, the potential for damaging gusts will increase across the discussion area this afternoon and early evening. Additionally, low-level shear will remain locally enhanced in the vicinity of a warm front across southeast PA/southern NJ. Deep-layer shear will be supportive of supercell structures, and the risk for tornadoes, potentially strong, will be maximized in this area. Convective trends will continue to be monitored, and a watch is likely prior to 18z. ..Bunting/Thompson.. 07/18/2026 ...Please see www.spc.noaa.gov for graphic product...

    Sounds like leaning towards Tornado Watch
  16. yoda
    TW up from CTP on a storm moving ESE... would be near HGR in a few hours
  17. yoda
    @high risk could there be some differential heating boundaries later? I'm assuming that with the rain/storms in PA, the WF will not push as far north and increase risk for a few tornadoes?
  18. yoda
    Should be getting a MCD soon, probably in next hour
  19. yoda
    S winds being reported on the 11am obs up to BWI... 84/75 S at 9 at DCA... C VA like CHO, Culpepper, EZF already upper 80s

    That's from 7am lol

    Looks like @CAPE got a flush hit
  25. yoda
    SPC also went 5% tor for areas NE of a line from basically HGR to DC... and CIG 1 for extreme NE MD into SE PA/NJ with mention of a few strong tornadoes
