SPC 1630Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1025 AM CST Fri Nov 29 2024 Valid 291630Z - 301200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected through tonight. ...Synopsis and Discussion... Broadly cyclonic flow aloft will persist over the eastern U.S. today. Surface high pressure over the southern Plains/Southeast and offshore low-level flow trajectories over the Gulf and western Atlantic are expected to generally limit thunderstorm potential across the CONUS through the period, with a couple of exceptions. A front will continue southward over the FL Peninsula, with limited low-level convergence due to weak/veered boundary-layer flow. While isolated convection may occur today along/near the front, this activity should generally remain elevated. A strong inversion noted between 670-630 mb on the 12Z TBW sounding should also limit updraft intensities. Finally, low-topped convection occurring with snow bands in the lee of the Lower Great Lakes may reach sufficient depth to support charge separation and occasional lightning flashes. ..Gleason/Wendt.. 11/29/2024
