SPC Jan 10, 2022 1300 UTC Day 1 Convective Outlook

SPC 1300Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0604 AM CST Mon Jan 10 2022 Valid 101300Z - 111200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... A few thunderstorms are expected across central and south Florida, mainly this afternoon/evening. ...FL mainly this afternoon/evening... In the wake of deep midlevel trough over the Northeast, a surface cold front will continue to move southeastward across the Gulf of Mexico and FL peninsula through tonight. Daytime heating across central/south FL and a diffuse pre-frontal trough will help focus the development of a few thunderstorms, mainly this afternoon/evening across southeast FL where there may be some local sea breeze enhancement. MLCAPE of 1000-1500 J/kg and weak vertical shear suggest that severe storms are unlikely. ...Elsewhere through tonight... A lake-effect snow band will persist through the afternoon off Lake Ontario. Shallow buoyancy is expected within this band, but the entire profile will be colder than -5 to -6 C, which suggests that lightning production will be sparse (if at all). Farther east, any ocean-effect convection deep enough to produce lightning flashes should remain well off the southeast New England coast tonight. ..Thompson/Leitman.. 01/10/2022 Read more LIVE: spc.noaa.gov
