Day 1 Convective Outlook 
NWS Storm Prediction Center Norman OK
1252 AM CDT Sat Jun 25 2022

Valid 251200Z - 261200Z

...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM THE
ILLINOIS VICINITY WEST-SOUTHWESTWARD TO THE TEXAS AND OKLAHOMA
PANHANDLE VICINITY...

...SUMMARY...
Isolated severe thunderstorms are possible from parts of the middle
Mississippi Valley into the Texas and Oklahoma Panhandle vicinity
this afternoon and evening, with a few posing at least some risk for
severe gusts and large hail.

...Synopsis...
An upper trough over the Canadian Prairie and adjacent northern
Plains states will continue moving slowly eastward today, reaching
the Upper Mississippi Valley/western Upper Great Lakes region
overnight.  Meanwhile, broad ridging will prevail over the entire
southern half of the country through the period.

At the surface, a cold front associated with the aforementioned
upper trough will continue moving southeastward across the central
third of the U.S. with time.  By afternoon, the front should extend
from the Upper Mississippi Valley to western portions of the
southern Plains, and from Lower Michigan to Texas by the end of the
period.

...Illinois vicinity west-southwestward to the Texas/Oklahoma
Panhandle area...
As a cold front shifts southeastward across central portions of the
country, heating/destabilization is forecast to occur in the
vicinity of the frontal zone, where a moist boundary layer will
reside.  As ongoing convection over the Upper Mississippi
Valley/Upper Great Lakes region lingers through the day, new storm
development is expected along the front, from the northern Illinois
vicinity west-southwestward to the Texas/Oklahoma Panhandle region.
Much of this convection may be to the cool side of the front,
especially from the lower Missouri Valley area westward.  Still,
with moderate mid-level westerlies near and just north of the front,
a few stronger storms may evolve locally -- capable of producing
hail and locally damaging wind gusts, mainly during the late
afternoon and evening hours.
