SPC MD 2027

Mesoscale Discussion 2027
NWS Storm Prediction Center Norman OK
0320 PM CDT Tue Aug 18 2026

Areas affected...Central/eastern Gulf Coast into North Florida

Concerning...Severe potential...Watch unlikely 

Valid 182020Z - 182215Z

Probability of Watch Issuance...5 percent

SUMMARY...Locally damaging winds are possible this afternoon. A
watch is not expected.

DISCUSSION...Scattered convection has developed along the Gulf
breeze front within a very moist (low 70s F dewpoints), high PWAT
(2-2.5 in.) airmass. 12Z/18Z observed soundings from the region
showed poor mid-level lapse rates. This, and very weak shear, will
keep storms unorganized. However, water-loaded downdrafts may
produce locally damaging winds with low-level lapse having steepened
substantially this afternoon.
