CONCERNING...SEVERE THUNDERSTORM WATCH 694...

VALID 031548Z - 031715Z

STRONG / SEVERE STORMS CONTINUE ACROSS SERN SD...AND SHOULD SPREAD
ESEWD ACROSS FAR SRN MN / NRN AND CENTRAL IA OVER THE NEXT SEVERAL
HOURS. NEW WW WILL BE ISSUED SHORTLY DOWNSTREAM OF WW 694.

LATEST RADAR LOOP CONTINUES TO INDICATE A SMALL BUT WELL-ORGANIZED
CLUSTER OF SEVERE STORMS...WHICH HAS PRODUCED STRONG / DAMAGING
WINDS IN THE 60 TO 80 MPH RANGE OVER THE PAST HOUR OR SO.

LOW-LEVEL AIRMASS FEATURING LOW 70S DEWPOINTS AND ELY WINDS
DOWNSTREAM OF ONGOING STORMS WILL CONTINUE TO ALLOW FAVORABLE INFLOW
INTO ONGOING CONVECTIVE LINE / BOW.  THIS ALONG WITH 30 TO 40 KT WLY
MID-LEVEL WINDS AND CONTINUED AIRMASS DESTABILIZATION SUGGESTS THAT
ONGOING STORM CLUSTER SHOULD REMAIN SEVERE AND LIKELY EXPAND /
INTENSIFY OVER THE NEXT FEW HOURS.  ALONG WITH SOME HAIL...STRONG /
GUSTY WINDS AND SOME LOCALLY SIGNIFICANT WIND DAMAGE WILL BE
POSSIBLE.
