URGENT - IMMEDIATE BROADCAST REQUESTED

Severe Thunderstorm Watch Number 464

  until 500 AM CDT.

SUMMARY...An initial cluster of elevated storms in northwestern

Minnesota may continue to expand and begin to develop more organized

structure while moving southeastward through the early morning

hours.  Given the possibility of a more organized convective system,

damaging winds will become more of a concern.  Otherwise, the

stronger embedded storms will pose a threat for large hail.



The severe thunderstorm watch area is approximately along and 65

statute miles north and south of a line from 35 miles west southwest

of Thief River Falls MN to 65 miles south of International Falls MN.

For a complete depiction of the watch see the associated watch

outline update (WOUS64 KWNS WOU4).
