DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK

VALID 171200Z - 181200Z

...DISCUSSION...
A DAMPENING SHORT WAVE TROUGH CENTERED OVER THE CNTRL/SRN ROCKIES
SHOULD DRIFT INTO THE CNTRL PLAINS...BECOMING EMBEDDED WITHIN A
BUILDING UPPER-LEVEL RIDGE OCCURRING DOWNSTREAM OF AN AMPLIFIED
TROUGH ENTERING THE WEST. LEE SURFACE TROUGH SHOULD PERSIST ACROSS
THE NRN/CNTRL HIGH PLAINS WITH A S/SWLY LLJ NOCTURNALLY
STRENGTHENING OVER THE GREAT PLAINS. THIS SHOULD AID IN A NOCTURNAL
INCREASE OF ELEVATED TSTMS WITHIN A WAA REGIME ACROSS THE UPPER
MIDWEST...N OF STRONG CAPPING. BUT WITH ONLY A MODEST PW INCREASE
AND WEAK UPPER-LEVEL FLOW WITH THE BUILDING RIDGE...ORGANIZED SEVERE
POTENTIAL APPEARS MINIMAL.
