SPC 1300Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0736 AM CDT Sat Oct 31 2020 Valid 311300Z - 011200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms should remain confined to parts of the southern Florida Peninsula today. Severe thunderstorms are not expected. ...Synopsis and Discussion... An upper trough will amplify over the central CONUS and MS Valley through tonight, while a surface cold front also surges eastward. Low-level moisture will likely remain insufficient to support any thunderstorms across these regions. The only appreciable risk for thunderstorms today appears to be confined to portions of the southern FL Peninsula, where a weak easterly wave and modest low-level convergence along sea breeze boundaries should be present. Although MLCAPE may increase to 1000-1500 J/kg this afternoon across south FL, weak shear is expected to limit thunderstorm organization. ..Gleason.. 10/31/2020
