Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0755 PM CDT Tue Apr 08 2025
Valid 090100Z - 091200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Organized severe weather is not expected through Wednesday morning.
Isolated strong storms remain possible over the next few hours in
South Florida and the Keys as well as western South Dakota.
...Synopsis...
A shortwave trough continues to approach the Florida Peninsula this
evening. A weak surface boundary that is currently offshore may
provide some focus for thunderstorms tonight. Another shortwave
trough in Montana is responsible for isolated strong convection
moving into western South Dakota. This activity may continue another
couple of hours before weakening.
...South Dakota...
The low-level airmass is quite dry; however, moisture is sufficient
for isolated convection on the southern fringe of the shortwave
trough. Small hail may occur with this activity, but the dry
boundary layer is more likely to support strong to potentially
marginally severe wind gusts. Activity should weaken over the next
couple of hours and coverage will remain too isolated for adding
severe probabilities.
...South Florida/Keys...
The approach of the shortwave trough may promote a modest increase
in convection along and near the surface boundary. Given diminishing
surface temperatures and increase MLCIN, storms will become
increasingly elevated with time. A strong gust could occur with the
strongest storms, but this potential should remain spatially
limited.
