Day 3 Convective Outlook 
NWS Storm Prediction Center Norman OK
0234 AM CDT Sun Jul 24 2022

Valid 261200Z - 271200Z

...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM THE
MID-ATLANTIC WEST INTO THE LOWER MISSOURI VALLEY...

...SUMMARY...
Severe thunderstorms will be possible Tuesday from the mid-Atlantic
region west to portions of the central Plains.  Damaging gusts will
be the primary severe hazard.

...Mid-Atlantic west to lower Missouri Valley...
A front, reinforced by convective outflows, will extend from the
mid-Atlantic coast west into the central Plains Tuesday afternoon.
As an upper-level low over Ontario Province moves south, some
increase in westerly mid-level flow will occur in the vicinity of
the front resulting in effective shear of 30-35 kts.  A very moist
air mass will remain in place with surface dew points generally in
the 70s, supporting moderate/pockets of strong buoyancy by
afternoon.  Thunderstorms developing in the vicinity of the front
will pose a risk for damaging downburst winds, aided by steep
low-level lapse rates in areas with more substantial heating. The
severe threat should generally diminish during the late evening.
