DISCUSSION...A line of thunderstorms has developed along a remnant outflow boundary across central PA. Ahead of this line of storms, temperatures are in the mid 80s to 90s with mid to upper 60s dewpoints. The downstream air mass is further characterized by MLCAPE around 500-1000 J/kg and steep low-level lapse rates. Weaker mid-level lapse rates are noted along with generally weak flow aloft. Nonetheless, this environment will support instances of strong to severe wind over the next couple of hours, should this line maintain intensity and progress eastward. ..Thornton/Edwards.. 06/17/2024 ...Please see www.spc.noaa.gov for graphic product...
