ZCZC SPCSWOMCD ALL ACUS11 KWNS 091550 SPC MCD 091550 FLZ000-091745- Mesoscale Discussion 2138 NWS Storm Prediction Center Norman OK 1050 AM CDT Wed Oct 09 2024 Areas affected...Parts of central Florida Concerning...Tornado Watch 690... Valid 091550Z - 091745Z The severe weather threat for Tornado Watch 690 continues. SUMMARY...The tornado threat north of Lake Okeechobee is increasing as a cluster of discrete supercells move generally northward. A strong tornado or two will be possible this afternoon. DISCUSSION...A cluster of discrete supercells continue to move north/north-northwest near Lake Okeechobee. Surface temperatures have risen into the low 80s F, with the most heating occurring in east-central Florida. The area where temperatures in the 80s and dewpoints in the upper 70s F will be where the tornado threat will be maximized this afternoon. The storm just west of Lake Okeechobee (Glades County) is currently producing a tornado per TDS evident on KMLB radar dual-pol data. Given the easterly flow and the expected strengthening of the low-level wind field with time (KMLB VAD data has shown slow improvement in low-level shear), the tornado threat north of Lake Okeechobee will continue to increase this afternoon. The environment will support a strong tornado or two with these storms. ..Wendt.. 10/09/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...MFL...MLB...TBW...
