NWS STORM PREDICTION CENTER NORMAN OK
0751 PM CDT MON APR 21 2025

VALID 220100Z - 221200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
A FEW STRONG STORMS MAY DEVELOP ACROSS PORTIONS OF IOWA LATER
TONIGHT, BUT HAIL SHOULD GENERALLY REMAIN BELOW SEVERE LEVELS.

...01Z UPDATE...

NOTABLE SHORT-WAVE TROUGH IS CURRENTLY LOCATED OVER THE NORTHERN
HIGH PLAINS. THIS FEATURE IS SHIFTING EAST AS A 500MB SPEED MAX
TRANSLATES ACROSS SD TOWARD NORTHERN IA. SCATTERED WEAK CONVECTION
IS NOTED AHEAD OF THIS FEATURE, ARCING FROM EASTERN SD INTO
NORTHEAST NE. LLJ SHOULD INCREASE ACROSS EASTERN NE/WESTERN IA THIS
EVENING IN RESPONSE TO THE SHORT WAVE, AND A CORRIDOR OF LOW-LEVEL
WARM ADVECTION SHOULD AID ADDITIONAL CONVECTION DOWNSTREAM. FORECAST
SOUNDINGS SUGGEST ELEVATED BUOYANCY WILL INCREASE SUCH THAT ROBUST
UPDRAFTS ARE POSSIBLE. WHILE STEEP LAPSE RATES FAVOR HAIL
PRODUCTION, INSTABILITY MAY BE A BIT TOO WEAK TO WARRANT MORE THAN
MARGINALLY SEVERE HAIL. FOR THESE REASONS WILL NOT INTRODUCE SEVERE
PROBABILITIES
