TimB Posted June 28 Share Posted June 28 One more heatwave stat: it was 81 at PIT at 8am Sunday (didn’t drop below 80 overnight that night). That’s the third warmest 8am temp ever observed at Pittsburgh International, behind 7/17/1988 and 6/29/2012, which were both 82 at 8am. Link to comment Share on other sites More sharing options...
Mailman Posted June 29 Share Posted June 29 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 Link to comment Share on other sites More sharing options...

Mailman Posted June 29 Share Posted June 29 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. Link to comment Share on other sites More sharing options...
