THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 444
CONTINUES.
SUMMARY...DAMAGING WIND AND ISOLATED HAIL REMAIN POSSIBLE OVERNIGHT.
DISCUSSION...PERSISTENT CONVECTION HAS REMAINED RELATIVELY
DISORGANIZED THUS FAR ACROSS PARTS OF NORTHEAST NE INTO WESTERN IA.
HOWEVER, SOME EAST-SOUTHEASTWARD PROPAGATION HAS RECENTLY BEEN NOTED
WEST OF SIOUX CITY, WHICH MAY BE AN INDICATION OF EXPANDING OUTFLOW
AND A GRADUALLY STRENGTHENING COLD POOL. IF THIS TREND CONTINUES, A
SOMEWHAT MORE ORGANIZED STORM CLUSTER MAY EVOLVE AND MOVE ALONG OR
JUST NORTH OF A FRONT DRAPED ACROSS WESTERN IA, WITH SOME UPTICK IN
DAMAGING-WIND POTENTIAL. OTHERWISE, MUCAPE OF ABOVE 2000 J/KG WILL
CONTINUE TO SUPPORT ISOLATED HAIL POTENTIAL WITH THE STRONGEST
EMBEDDED UPDRAFTS OVERNIGHT.
