Day 3 Convective Outlook 
NWS Storm Prediction Center Norman OK
0155 AM CDT Sat Jul 20 2024

Valid 221200Z - 231200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe-thunderstorm potential appears low on Monday.

...Synopsis...

The overall pattern will not change much on Monday. An upper ridge
in the West and trough over the central/eastern U.S. will persist
amid weak deep-layer flow. A seasonally moist airmass will remain in
place east of the Rockies, supporting widespread thunderstorm
activity. Much of this activity will likely remain disorganized
given weak vertical shear and a little upper support.

Some forecast guidance suggests a weak cold front will develop
southward across the Canadian Prairies into ND and the Upper
Midwest. However, the timing of this feature is uncertain, and may
be ill-timed with the diurnal cycle/better thermodynamic conditions.
Vertical shear is forecast to remain weak regardless, and confidence
is too low to include severe probabilities at this time. Elsewhere,
sporadic strong gusts may acco*pany thunderstorms across the
south-central/southeast states where high PW values will be in
place, though this activity should remain mostly disorganized,
pulse-type convection.
