Day 2 Convective Outlook 
NWS Storm Prediction Center Norman OK
1130 PM CDT Sun Sep 04 2022

Valid 061200Z - 071200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

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

...Discussion...
As one significant perturbation within the westerlies shifts east of
the Canadian Northwest Territories and Prairies, and another more
co*pact impulse slowly accelerates toward the British
Columbia/Pacific Northwest coast, models indicate that broad
mid-level ridging centered over the Great Basin may expand and build
further during this period.  Downstream, weaker mid-level troughing
is forecast to advance southeast of the Canadian Maritimes and New
England coast, acco*panied by the leading edge of more substantive
lower/mid-tropospheric cooling and drying.  Otherwise, seasonably
moist conditions will persist to the south of the frontal zone, and
southeast of weak positively tilted mid-level troughing lingering
along an axis from the lower Ohio through lower Mississippi Valleys
into the northwestern Gulf coast.  It still appears that this
environment will again beco*e supportive of scattered to numerous
thunderstorms on Tuesday, particularly during the afternoon and
evening.  Some of these could be acco*panied by gusty winds, but
probabilities for severe storms appear generally negligible (less
than 5 percent).
