Mesoscale Discussion 0267 NWS Storm Prediction Center Norman OK 1118 AM CDT Sun Apr 15 2018 Areas affected...west central Florida Concerning...Tornado Watch 51... Valid 151618Z - 151715Z The severe weather threat for Tornado Watch 51 continues. SUMMARY...Storms will likely move onshore near the Tampa area around 17Z and may pose a risk for mainly strong to damaging wind, but a brief tornado cannot be ruled out. This area is south of tornado watch 51, but the existing WW can be locally extended a few counties south as needed, or a separate severe thunderstorm watch could be issued. Plans are also to expand the slight risk farther south through remainder of the Tampa forecast area with the 1630Z update. DISCUSSION...Line of storms with broad bow echo configuration located off the west central FL coast is moving east around 30 kt and will reach the coast near Tampa around 17Z. The atmosphere inland is moist with upper 70s surface dewpoints and temperatures rising through the 80s supporting MLCAPE around 1500 J/kg. Some increase in low-mid level winds is expected next hour or two. The overall environment with strong low-level and deep shear, moderate instability and influence of MCV located near northern end of the bowing segment appear supportive of a organized structures with a threat for damaging wind as the line moves inland. ..Dial.. 04/15/2018 ...Please see www.spc.noaa.gov for graphic product...
