MD 0492 CONCERNING SEVERE THUNDERSTORM WATCH 128… FOR EASTERN OH…WV PANHANDLE…WESTERN PA

Mesoscale Discussion 0492 NWS Storm Prediction Center Norman OK 0546 PM CDT Wed Apr 05 2023 Areas affected...Eastern OH...WV Panhandle...Western PA Concerning...Severe Thunderstorm Watch 128... Valid 052246Z - 060015Z The severe weather threat for Severe Thunderstorm Watch 128 continues. SUMMARY...Gusty winds will continue to be observed with convection this evening. DISCUSSION...Seasonally warm surface temperatures (low-mid 80s) have contributed to very steep low-level lapse rates across the upper OH Valley. Thermodynamic profiles continue to favor gusty downdrafts given the 30F surface temp/dew point spreads. While SBCAPE is somewhat marginal, strong shear and PWs in excess of 1 inch suggest locally strong downbursts may continue into the early evening hours before temperatures begin to cool. Some of this activity may spread into western PA before weakening. ..Darrow.. 04/05/2023 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...PBZ...CLE...
