SPC AC 190017
Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0717 PM CDT Sun Apr 18 2021
Valid 190100Z - 191200Z
...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS OVER PARTS OF
CENTRAL AND NORTHERN FLORIDA...
...SUMMARY...
Marginal hail or wind gusts remain possible across parts of northern
into central Florida.
Strong westerly flow aloft will persist over the southeastern states
as a shortwave trough moves from TN into the Carolinas. A
convectively reinforced boundary will drift south across northern FL
through the period, with a moist and unstable air mass supporting
storms along/ahead of it. Deep-layer shear in excess of 40 kt may
aid storm longevity, but the overall severe threat will remain low
with only sporadic strong storms expected with marginal hail or wind
threat.
