Valid 230722Z - 230845Z The severe weather threat for Tornado Watch 24 continues. SUMMARY...An isolated severe/tornado risk continues across the southern extent of WW 24, as a broken band of storms advances through South Florida during the next 3-4 hours (until 10-11Z). DISCUSSION...At 0715Z, mosaic radar imagery continued to show a broken band of discrete storms stretching southwest from Palm Beach County to southern Collier/northwest Monroe Counties. A few will continue to evolve into supercells with transient low-level rotation couplets. Recent couplets include storms along central border area of Palm Beach/Broward Counties, across eastern Palm Beach County, southeast Collier County, and moving toward the central coast of mainland Monroe County. Moderate instability along and south of these storms combined with strong deep-layer and low-level shear suggests a tornado threat persists with this activity, as area VWP data indicated 0-1 km SRH of 350-400 m2/s2. ..Peters.. 01/23/2017 ...Please see www.spc.noaa.gov for graphic product...
