AREAS AFFECTED...SERN SD/SWRN MN/NRN NE/NWRN IA

CONCERNING...TORNADO WATCH 321...

VALID 300221Z - 300315Z

CONVECTION IN WW 321 IS SOMEWHAT DISORGANIZED...AS MAIN LINE OF
STORMS EXTENDS FROM 65 N ATY/RWF/25 NNE SUX. THREAT FOR LARGE HAIL
AND WIND SHOULD BE MAIN CONCERNS...THOUGH VWP DATA FROM SIOUX FALLS
INDICATE AROUND 30 KT 0-1KM SHEAR. AIRMASS QUALITY IS NOT AS GOOD
FARTHER EAST IN E CNTRL MN WITH SFC DEWPOINTS IN THE LOW-MID 50S.
LOW LEVEL JET NEAR 50 KT WILL FOCUS EAST ACROSS SRN/CNTRL MN...AND
SO LARGE SCALE CONDITIONS SUPPORT DEVELOPMENT OF MCS INTO THE
OVERNIGHT HOURS. TORNADO THREAT SHOULD BE DIMINISHING HOWEVER.

A WW IS BEING ISSUED FOR PORTIONS OF NE/IA...AND WE WILL MONITOR MN
STORMS FOR TRENDS. IF STORMS DO NOT WEAKEN WITH TIME...ANOTHER WW
WILL BE CONSIDERED FARTHER EAST THAN WW 321.
