Areas affected...Southeast NE...IA...Northern MO
Concerning...Tornado Watch 375...
Valid 282229Z - 290000Z
The severe weather threat for Tornado Watch 375 continues.
SUMMARY...Severe threat continues across WW375.
DISCUSSION...An elongated corridor of severe thunderstorms has
evolved within the base of a strong short-wave trough over the Upper
MS Valley. Numerous supercells are noted from extreme southeast NE,
through central IA into southwest WI, though storm mergers are
beginning to take place which may lead to an MCS-like cluster if
trends continue. Shear profiles remain favorable for storm rotation
and potential tornadoes along with very large hail. With time
convection should spread across the remainder of WW375 focusing
along the IA/MO border and IA/IL border later this evening.
