Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0749 PM CDT Wed Oct 07 2020 Valid 080100Z - 081200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... No severe thunderstorms are expected across the continental United States this evening or tonight. ...DISCUSSION... An upper-level trough will move from the coast of New England eastward into the western Atlantic this evening. At the surface, a cold front will advance southeastward across the Mid-Atlantic and Ohio Valley as a cool and dry airmass overtakes much of the northeastern U.S. Further south in the eastern Gulf Coast states, a moist airmass is in place with surface dewpoints in the lower to mid 70s F. Isolated thunderstorms will be possible across parts of central and northern Florida in a pocket of moderate instability where the RAP is analyzing MLCAPE in the 1000 to 1200 J/kg range. Deep-layer shear is weak in north-central Florida and will limit any potential for a severe threat. Elsewhere across the United States, thunderstorm development is not expected this evening and tonight. ..Broyles.. 10/08/2020
