  1. Gonna have to get lucky with a squall to get some accumulation down here.
  2. Might have a little something in the air in about a week.
  3. A little wind and rain down this way. Nothing too drastic. Friday, however, is looking rather wet. Not looking forward to that at all.
  4. But what do I know... US National Weather Service Pittsburgh PA 4:10 PM - There is a lull in activity over eastern OH into western PA, but we're expecting some environmental "recovery" in the next hour or so as clouds break across the area. Isolated to scattered storms may redevelop in this area in the next several hours, so the Watch continues.
  5. The activity that was to my southwest dissipated. Think the storm that was up (well downstream) the river had some impact locally. Won't complain.
  6. Mesoscale Discussion 1472 NWS Storm Prediction Center Norman OK 1103 AM CDT Sat Jun 29 2024 Areas affected...Portions of OH...northern WV...and western PA Concerning...Severe potential...Watch possible Valid 291603Z - 291800Z Probability of Watch Issuance...60 percent SUMMARY...Thunderstorms are expected to increase in coverage and intensity over the next few hours. Damaging gusts will be the main hazard with this activity, though a tornado or two also may occur. Timing of watch issuance is uncertain, but area is being monitored for watch issuance within the next couple of hours. DISCUSSION...Isolated convection has been slowly increasing along the leading edge of an area showers left over from overnight/early morning convection moving into northern/central OH. Rich boundary-layer moisture is in place, with surface dewpoints in the upper 60s to low 70s F noted in morning observations. Widespread cloudiness is limiting heating, and temperatures are generally in the upper 70s to near 80F. With time, pockets of stronger destabilization are expected into afternoon, with downstream destabilization expected into parts of northern VA/western PA by early to mid-afternoon. However, cloud cover and poor lapse rates may limit more widespread stronger instability. Nevertheless, vertical shear will be sufficient for transient supercells and bands of bowing segments. Damaging gusts will be the main hazard with convection through the afternoon and into early evening. While low-level shear will remain somewhat weak, vertically veering profiles will result in somewhat enlarge and curved low-level hodographs suitable for a tornado or two in addition to damaging gust potential. Additional convection is possible into the evening hours as the synoptic cold front (currently over northern IL) shifts east/southeast across the area. As a result, multiple bands/rounds of strong/severe storms are possible. Timing of watch issuance is a bit uncertain, but the trends will continue to be monitored for possible watch issuance within the next couple of hours. ..Leitman/Gleason.. 06/29/2024
  7. Looks like they got it pretty good in portions of Westmoreland.
  8. Think they're covering their butts now from May.
  9. Mesoscale Discussion 1383 NWS Storm Prediction Center Norman OK 1242 PM CDT Sun Jun 23 2024 Areas affected...Portions of the Ohio River Valley into southern New York Concerning...Severe potential...Watch likely Valid 231742Z - 231945Z Probability of Watch Issuance...80 percent SUMMARY...Severe storm risk will gradually increase through the afternoon, with damaging winds being the primary concern. A watch will likely be issued for parts of the area in the next few hours. DISCUSSION...Ahead of a northeast/southwest-oriented cold front draped across the OH River Valley, a corridor of upper 60s to lower 70s dewpoints and pockets of heating will contribute to moderate surface-based instability -- despite poor midlevel lapse rates sampled by 12Z observed soundings. As modest midlevel height falls overspread the region, surface-based thunderstorms should gradually increase in coverage along/ahead of the cold front. Storms should slowly increase in intensity as they track eastward and intercept the destabilizing warm/moist sector. Given ample deep-layer westerly flow/shear (around 35-kt effective shear) roughly perpendicular to the front, a mix of loosely organized clusters and transient supercells are expected. Steepening low-level lapse rates and the enhanced low/midlevel flow will favor locally damaging gusts as the primary concern, especially with any localized upscale growth. However, marginally severe hail and a tornado or two cannot be ruled out, especially with any sustained semi-discrete supercells. A watch (potentially two separate watches) will likely be issued for parts of the area in the next few hours. ..Weinman/Hart.. 06/23/2024
  10. Quarter-size hail over at Cal U. They can have it, though.
  11. Thunder/lightning and rain here. Wind wasn't anything noteworthy.
