  1. Mesoscale Discussion 1443 NWS Storm Prediction Center Norman OK 0246 PM CDT Fri Aug 04 2017 Areas affected...Lower Great Lakes/Allegheny Plateau region Concerning...Severe Thunderstorm Watch 439... Valid 041946Z - 042145Z The severe weather threat for Severe Thunderstorm Watch 439 continues. SUMMARY...Small to, perhaps, marginally severe hail and localized/spotty damaging wind gusts will remain possible near thunderstorm activity overspreading the region through early evening. DISCUSSION...Potential for substantive further organization of ongoing pre-cold frontal convective development into the 21-23Z time frame is appearing increasing unlikely, as objective analysis indicates that deep layer vertical shear remains weak across much of the warm sector south and east of Lakes Erie and Ontario. However, mean lower/mid tropospheric wind fields are strengthening to 30-40 kt across western Pennsylvania and much of New York state. And this could continue to augment severe weather potential with thunderstorm activity developing northeastward/eastward across the region through the remainder of the afternoon, primarily associated with localized enhanced downward transfer of momentum within areas of heavier precipitation loading. ..Kerr.. 08/04/2017

  3. Mesoscale Discussion 1442 NWS Storm Prediction Center Norman OK 1038 AM CDT Fri Aug 04 2017 Areas affected...Much of the upper Ohio Valley Concerning...Severe potential...Watch possible Valid 041538Z - 041745Z Probability of Watch Issuance...40 percent SUMMARY...Severe hail/wind risk with increasing thunderstorm development may remain somewhat localized and/or sparse in coverage through early to mid afternoon. However, potential does exist for a slow increase in coverage and organization which could be accompanied by a more substantive risk for damaging wind gusts later this afternoon. Trends will continue to be monitored for the possibility of a watch. DISCUSSION...Weak to moderate pre-cold frontal destabilization is now underway across much of the upper Ohio Valley, primarily as insolation contributes to warming of a seasonably moist boundary layer. Latest objective analysis suggests that inhibition is already becoming increasingly negligible, particularly within a corridor ahead of the front, from parts of north central Kentucky through the Lake Erie area. Aided by large-scale ascent ahead of a significant short wave trough now pivoting eastward toward the lower Great Lakes/upper Ohio Valley region, a general increase in thunderstorm activity appears likely through 17-20Z. Further daytime heating may yield CAPE as high as 1500-2000 J/kg, supportive of vigorous updrafts. However, warm sector southwesterly deep layer mean flow, even with some strengthening, appears likely to remain on the order of 30-35 kt. And models indicate that the mid-level cold core of the approaching system will lag to the west. Still, weak cooling aloft may be enough to support some risk for marginally severe hail in initial stronger pulsing activity. Vertical shear and instability may become marginally sufficient to support a gradual increase in convective organization, which may eventually be accompanied by an increasing risk for potentially damaging wind gusts. This probably will take some time through, with any severe hail/wind risk expected to initially remain fairly sparse in coverage. ..Kerr/Goss.. 08/04/2017
  4. Mesoscale Discussion 1364 NWS Storm Prediction Center Norman OK 0250 PM CDT Thu Jul 20 2017 Areas affected...Eastern/southern OH...western/central PA...northern WV Concerning...Severe potential...Watch unlikely Valid 201950Z - 202215Z Probability of Watch Issuance...20 percent SUMMARY...Isolated damaging-wind potential could accompany thunderstorms moving across portions of the middle and upper Ohio Valley region to the central Appalachians and vicinity into the early evening hours. Watch issuance is presently unlikely. DISCUSSION...Thunderstorm development continues along a diffuse cold front from northwest PA through north-central OH. Additional storm development may also focus along the northern and eastern periphery of a residual MCV presently moving across southwest OH. MCV-related ascent is being augmented by differential-heating-induced baroclinic circulations along fringes of multi-layered cloud decks surrounding the MCV. The air mass south of the front and ahead of the MCV has become moderately unstable, owing to surface temperatures having warmed through the 80s amid dewpoints in the upper 60s to around 70F. The most intense storms may produce locally damaging wind gusts -- aided by slightly enhanced deep shear (around 20-40 kt of effective shear). However, stronger deep shear resides north of this region, which should limit overall convective organization. Moreover, poor mid-level lapse rates, veered low-level flow ahead of the front limiting frontal convergence, and modest background low-level flow strength should prevent a more substantial severe risk from occurring. ..Cohen/Coniglio/Hart.. 07/20/2017
  5. Mesoscale Discussion 1276 NWS Storm Prediction Center Norman OK 0208 PM CDT Mon Jul 10 2017 Areas affected...Southeast OH...Southwest PA...and Northern WV Concerning...Severe potential...Watch possible Valid 101908Z - 102115Z Probability of Watch Issuance...40 percent SUMMARY...Scattered strong and occasionally severe storms will affect parts of southeast OH, southwest PA, and northern WV this afternoon. This area will be monitored for a possible watch if trends warrant. DISCUSSION...A long-lived MCV (remnant from overnight convection) is moving eastward across western OH. The air mass ahead of this feature is only slowly destabilizing due to extensive cloud cover and scattered precipitation. However, partly cloudy skies in the southeast flank of the MCV over southeast OH are helping temperatures to warm through the 70s with near 70F dewpoints. While low-level lapse rates are somewhat limited today, low-level wind fields are relatively strong as depicted by ILN VWP data. Continued heating will likely lead to scattered thunderstorm development, with sufficient vertical shear for a few organized/bowing convective segments. Sufficient CAPE may also promote a risk of hail in the strongest cells. Convective trends will be monitored in this region for the possibility of a watch if bowing structures becomes evident/more likely. ..Hart/Darrow.. 07/10/2017

  7. A trained spotter claimed there was a rope tornado on the ground south of Uniontown. I still haven't come across any videos/pictures. EF1 tornado was confirmed in Washington County.
  8. I haven't seen any damage pictures for Fayette County. I did see some for the tornado warning in Washington County.
  9. Looks like there might be a weak area of rotation just to my south. No warning from PBZ, though. But they are the experts.

  11. Mesoscale Discussion 1131 NWS Storm Prediction Center Norman OK 1215 PM CDT Fri Jun 23 2017 Areas affected...Northern KY...Southern/eastern OH...Western WV...Western PA Concerning...Severe potential...Watch possible Valid 231715Z - 231915Z Probability of Watch Issuance...40 percent SUMMARY...A gradual increase in the threat for damaging wind gusts and perhaps a tornado or two is expected this afternoon. Watch issuance is possible. DISCUSSION...A gradual increase in the intensity and coverage of convection has been noted across portions of southern OH, in advance of a large precipitation shield (with embedded convection) further to the northwest. While midlevel lapse rates are poor, given the influence of the decaying tropical system to the southwest, modest heating within a very moist environment has resulted in moderate destabilization, with SBCAPE rising into the 1000-1500 J/kg range where temperatures have warmed into the low 80s F. Further intensification is possible, both with the more discrete activity across southern OH and northern KY, and within the larger convective plume across central/northern OH as that moves eastward. With strong deep-layer southwesterly flow over the region, effective shear has increased into the 40-50 kt range, which is more than sufficient for some organized storm structures. With unidirectional wind profiles in place, damaging wind gusts are expected to the primary threat, though low-level shear is sufficient for a tornado or two with any semi-discrete supercells that can evolve. Watch issuance is possible later this afternoon to cover this threat. ..Dean/Guyer.. 06/23/2017

  15. Mesoscale Discussion 0928 NWS Storm Prediction Center Norman OK 0105 PM CDT Wed May 31 2017 Areas affected...Eastern OH...Western PA...Northern WV Concerning...Severe potential...Watch unlikely Valid 311805Z - 311930Z Probability of Watch Issuance...20 percent SUMMARY...Isolated hail and damaging wind gusts are possible over the next several hours as thunderstorms move across eastern OH, western PA, and far northern WV. DISCUSSION...Storms have developed over the past hour within the modestly unstable airmass across central OH. Primary forcing for this increased convection is likely the shortwave trough currently pivoting through the southwestern periphery of the large upper low centered over Ontario. Despite relatively scant low-level moisture, some instability has developed ahead of these storms across central OH and western PA, largely as a result of cool mid-level temperatures (around -19 deg C at 500 mb) and modest surface heating. Unidirectional shear profiles will support fast storm motion and the potential for a few strong wind gusts with the more robust updrafts. Additionally, the enhanced flow aloft and resulting potential updraft organization is supportive of an isolated hail threat. Limited severe coverage is currently expected, precluding higher watch probabilities. Even so, convective trends across the area will be monitored closely. ..Mosier/Hart.. 05/31/2017
