MD 2350 CONCERNING TORNADO WATCH 677... FOR THE FLORIDA PANHANDLE Mesoscale Discussion 2350 NWS Storm Prediction Center Norman OK 0448 PM CDT Fri Oct 09 2026 Areas affected...The Florida Panhandle Concerning...Tornado Watch 677... Valid 092148Z - 092315Z The severe weather threat for Tornado Watch 677 continues. SUMMARY...The main tornado threat this evening will be near the coast as supercells east of the hurricane core interact with a surface warm front. DISCUSSION...Hurricane Isaias will make landfall this evening along the western FL Panhandle coast (see latest NHC advisories for details).

These surface conditions will contribute to surface-based buoyancy near and a little inland from the coast over the next few hours. The VWP from KTLH shows a large, curved hodograph and estimated 0-1 km SRH has roughly doubled since 19z with largely streamwise vorticity in the low levels. ...
