    Actually for i95 corridor and Delmarva
  9. yoda
    Severe Thunderstorm Watch up until 2am
  10. yoda
    Or..... could just wait a few more minutes lol
  11. yoda
    Understood, and I hate to criticize SPC... but they went watch likely and 80% chance for basically all of us into Delmarva.... to nothing
  12. yoda
    I guess we arent getting a watch then?

    Mesoscale Discussion 2221 NWS Storm Prediction Center Norman OK 0519 PM CDT Thu Sep 03 2026 Areas affected...Portions of the Mid-Atlantic Concerning...Severe potential...Watch likely Valid 032219Z - 040015Z Probability of Watch Issuance...80 percent SUMMARY...Ongoing Mesoscale Convective Systems will continue to move southeast this evening. The airmass ahead of these storms remains very hot and unstable. A wind damage threat is expected to persist into the greater Washington D.C. area later this evening. As such, a new watch will likely be needed. DISCUSSION...Multiple southeast moving mesoscale convective systems (MCS) are ongoing across portions of northern/eastern Ohio and western Pennsylvania. The leading MCS is currently located across the greater Pittsburgh area, with the trailing MCS across moving across northern Ohio and southern Lake Erie. Effective layer shear across these linear MCSs is characterized by 30-40 knots, which is more than sufficient to support ongoing organization as the clusters move southeast. Additionally, the airmass ahead of these storms remains very hot and humid, with surface temperatures in the 90Fs and dewpoints in the low-to-mid 70Fs. The result is steep low-level lapse rates and MUCAPE in excess of 3000 J/kg ahead of these storms, all the way into the greater Washington D.C. area. As evening progresses and the boundary layer cools, low-level lapse rates will weaken. However, the degree of thunderstorm organization and the very unstable environment ahead of the MCSs will maintain a threat for damaging wind well into the evening hours. A new watch will likely be needed to the southeast of ongoing watches across Pennsylvania, Ohio, and West Virginia. ..Marsh/Smith.. 09/03/2026 ...Please see www.spc.noaa.gov for graphic product...

    Doubt they will be as strong if they reach here... but... this is headed into Pittsburgh metro shortly Severe Weather Statement National Weather Service Pittsburgh PA 531 PM EDT Thu Sep 3 2026 OHC029-PAC003-007-019-125-WVC029-032200- /O.CON.KPBZ.SV.W.0335.000000T0000Z-260903T2200Z/ Columbiana OH-Allegheny PA-Beaver PA-Butler PA-Washington PA- Hancock WV- 531 PM EDT Thu Sep 3 2026 ...SEVERE THUNDERSTORM WARNING REMAINS IN EFFECT UNTIL 6 PM EDT FOR SOUTHEASTERN COLUMBIANA, NORTHWESTERN ALLEGHENY, NORTHWESTERN WASHINGTON, SOUTHERN BUTLER, BEAVER AND HANCOCK COUNTIES... At 531 PM EDT, severe thunderstorms were located along a line from 6 miles northeast of Zelienople to near Midland, or along a line from 10 miles west of Butler to 7 miles southeast of East Liverpool, moving southeast at 20 mph.

    LWX AFD did mention a boundary in the area
  18. yoda
    Although they seem more piecemeal, 19z and 20z HRRR are speeding up the "threat"... now it arrives around 11pm to midnight. Earlier HRRR runs were after midnight to 3am
  19. yoda
    I see golf ball sized hail and winds to 70mph in the warnings ETA - LSRs coming out with numerous trees, power lines, and power poles downed

    https://www.spc.noaa.gov/products/watch/ww0650.html URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 650 NWS Storm Prediction Center Norman OK 435 PM EDT Thu Sep 3 2026 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Western Maryland Western and Central Pennsylvania Eastern West Virginia * Effective this Thursday afternoon from 435 PM until Midnight EDT. * Primary threats include... Widespread damaging wind gusts to 70 mph likely Isolated large hail events to 1.5 inches in diameter possible A tornado or two possible SUMMARY...Multiple rounds of severe storm clusters are expected to move into the region from the northwest and impact the region this evening, with wind damage as the most common hazard.

    https://www.spc.noaa.gov/products/md/md2218.html Mesoscale Discussion 2218 NWS Storm Prediction Center Norman OK 0316 PM CDT Thu Sep 03 2026 Areas affected...Eastern Ohio into central Pennsylvania...western Maryland...and far northern West Virginia Concerning...Severe Thunderstorm Watch 649... Valid 032016Z - 032215Z The severe weather threat for Severe Thunderstorm Watch 649 continues. SUMMARY...Supercells across eastern Ohio and northwestern Pennsylvania will likely grow upscale and pose a more substantial wind threat downstream into central Pennsylvania through the evening. Downstream watch issuance is expected soon. DISCUSSION...Discrete to semi-discrete supercells are evident in regional radar imagery across northeast OH and northwest PA with a few instances of severe hail noted over the past hour. Regional VWPs continue to sample elongated hodographs favorable for splitting supercells with an attendant threat for large hail for the next hour or so. Given the propensity for splitting cells and tight clustering of convection, upscale growth into one or more organized lines appears probable over the coming hours. As this occurs, the potential for severe wind should increase as convection moves into central PA where air mass recovery has been ongoing through the afternoon (MLCAPE has increased to 1000-1500 J/kg per recent mesoanalysis estimates). ..Moore.. 09/03/2026 ...Please see www.spc.noaa.gov for graphic product...

    Watch needed soon for PA into parts of W and N MD per MCD
  23. yoda
    @high risk when looking at future radar, should i be looking more at composite or 1km AGL? Or neither lol
  24. yoda
    Granted its 1km AGL reflectivity and composite reflectivity, but I don't hate what the 18z RRFS is showing between 02z and 06z for the region
  25. yoda
    Fwiw, both 16z and 17z HRRR have an MCS/line/complex come rolling through the region between midnight and 3am. 17z HRRR encompasses more of the region than the 16z run did. Not saying its severe, just something to think about overnight as we watch it develop out to our NW ETA - 18z HRRR same idea... but an hour or so faster
