SPC 1630Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1028 AM CST Tue Feb 16 2021 Valid 161630Z - 171200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... The risk for organized severe thunderstorms appears negligible through tonight. ...Southeast FL... As advertised in the prior outlook, low-level winds have weakened and veered per recent AMX VWP data with a pronounced weakness in mid-level flow around 500 mb. This suggests the risk for additional supercells will remain negligible. Some uptick in thunderstorm coverage should occur this afternoon as the arctic front settles south before stalling. Potential will exist for small hail in the deepest updrafts given moderate buoyancy and moderate speed shear from 400 to 250 mb. Hail-laden downdrafts may aid in a few microbursts capable of strong wind gusts. ..Grams.. 02/16/2021
