    Have a feeling the Philly area and points east and south which received practically nothing from the first round will get the most out of the second round later - opinions ?

    Thunder again

    Hang in there. For many cycles now the HRRR has been advertising a very quick pullout of the smoke this afternoon. Already getting much better down this way.

    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 would go overtop that... I guess your idea would work
  6. The Iceman
    Yes, that was also a very messy convective day in the morning but it didn’t matter because the deep layer shear was in place. Very similar set up.
  7. Hoth
    Fine by me. Took a week to finish cutting up the trees that fell during the 7/4 storm.

    It does, although as their discussion mentions, the wind profiles are much more supportive of tornadoes to our northeast. Personally, I would put a tornado box over NJ, DE, southeast PA, and a severe box over MD and VA, but I can see where those shapes don't really fit around the initial box over PA.

    I especially like the guy sweeping the water away…

    Sounds like a tornado watch is incoming… pretty strong wordage in the Mesoscale discussion: 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.

    The lightning in these overnight cells gets intense, and if you happen to find yourself under one, look out. I had a tree struck around 2AM here. Virtually no wind. Just periods of frequent CGs.

    Bouts of very heavy rain in CNJ

    Intense rain and lightning
  16. winterwx21
    I've always noticed that warm front storms have the most lightning.

    Visiting Stone Mountain State Park NW of Winston-Salem. Not to hot but quite humid. Late morning thunder booming as we hit the summit was neat.

    Below is the first time I have used AI (Claude) to help analyze the Chester County Data set with data from 1893 to Present. Below is the average number of 90+ days by station and month. Including the years of record and the overall annual average. It did this correctly! see below.

    Gotta love warm front storms , sometimes they produce the best.

    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...

    Growing concerned looking at the parameters and sun is beating down nicely at the moment. Lots of little boundaries as well that could enhance some supercells.. assuming development continues upstream.

    Coming down in buckets. This is wonderful.
