Day 1 Convective Outlook  
NWS Storm Prediction Center Norman OK
1251 AM CDT Fri Mar 27 2026

Valid 271200Z - 281200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Isolated thunderstorms are expected today from the Ohio Valley into
North Carolina and Virginia but no severe threat is forecast.

...DISCUSSION...
An upper-level trough will dig southeastward across the eastern U.S.
today. At the surface, a cold front will advance southward into the
southern Appalachians and Carolinas. Behind the front, isolated
thunderstorm development with a potential for a few strong gusts,
will be possible in weak instability this afternoon. Elsewhere
across the continental U.S., thunderstorms are not expected today or
tonight.

Day 2 Convective Outlook  
NWS Storm Prediction Center Norman OK
1249 AM CDT Fri Mar 27 2026

Valid 281200Z - 291200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Isolated thunderstorms will be possible Saturday afternoon across
portions of the Florida peninsula, but the potential for severe
thunderstorms is low.

...Synopsis...
A strong cold front currently pushing southward across the Plains
and OH Valley is forecast to reach central to southern Florida by
Saturday afternoon. Continued displacement from the primary synoptic
low and upper wave to the northeast will lead to a gradual abatement
of frontal advancement and the onset of frontolysis through the day.
Despite diminishing low-level forcing for ascent, event modest lift
within an unstable and weakly capped environment will likely support
isolated to widely scattered thunderstorms by peak heating into
early evening. Very weak winds (less than 20 knots) through much of
the column will limit storm organization and the potential for
severe convection. Elsewhere across the country, dry and stable
conditions in the wake of the frontal passage will limit
thunderstorm potential.

Day 3 Convective Outlook  
NWS Storm Prediction Center Norman OK
0226 AM CDT Fri Mar 27 2026

Valid 291200Z - 301200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Isolated thunderstorms are possible across the southern Florida
peninsula and portions of southern Arizona Sunday afternoon and
evening. Severe thunderstorms are not expected.

...Synopsis...
An upper-level ridge (currently in place over the Southwest) is
forecast to shift east over the Plains through the day Sunday.
Broad-scale subsidence/height rises ahead of the ridge will promote
mostly dry and stable conditions for the central and eastern CONUS.
Thunderstorm potential will most likely be relegated to the southern
FL peninsula where weak ascent within a residual frontal zone (aided
by diurnally-drive sea breeze boundaries) may support a few
thunderstorms within a moist and weakly capped environment. While
confidence is lower, isolated convection appears possible across
parts of southern Arizona late Sunday afternoon where modest
low-level moisture advection, coupled with ample daytime heating,
steep mid-level lapse rates, and weak ascent from a mid-level
impulse may support high-based convection. Based on forecast
thermodynamic profiles, conditions may be supportive of strong
downburst winds. However, confidence in storm coverage and the
severe wind potential is too low for highlights.
