Day 2 Convective Outlook 
NWS Storm Prediction Center Norman OK
1130 PM CDT Sat Sep 03 2022

Valid 051200Z - 061200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
The risk for severe thunderstorms appears negligible across the
U.S., Monday through Monday night.

...Discussion...
Within the westerlies, models indicate that significant lower/mid
tropospheric cyclogenesis is possible during this period, but well
to the north of the international border, across the Canadian
Northwest Territories.  Another vigorous, but more co*pact,
perturbation may evolve over the northeastern Pacific by late Monday
night. 

Across much of the U.S., models indicate little substantive change
to the large-scale flow from Sunday into Monday. The center of a
broad mid-level high may begin to beco*e a bit more prominent once
again across the Great Basin.  Weak mid-level troughing acco*panied
by more appreciable lower/mid tropospheric drying may shift south of
the St. Lawrence Valley and lower Great Lakes region.  Otherwise,
seasonably moist conditions likely will persist along, south and
east of a lingering weak positively tilted mid-level trough axis
trailing west-southwestward across the Ohio through lower
Mississippi Valleys and southeast Texas.  This may again provide
support for scattered to numerous afternoon into early evening
thunderstorms on Monday.  Some of these could be acco*panied by
locally gusty winds, but the risk for severe thunderstorms, in
general, still appears negligible.
