   Concerning...Severe Thunderstorm Watch 377...379...

   Valid 030242Z - 030415Z

   The severe weather threat for Severe Thunderstorm Watch 377, 379
   continues.

   SUMMARY...Marginally severe hail and gusty winds remain possible
   with convection this evening.

   DISCUSSION...Numerous thunderstorm clusters have developed across
   southeast ND/eastern SD into western MN within a focused warm
   advection corridor. LLJ is forecast to increase across MN into the
   late-evening hours ahead of northern Plains short-wave trough.
   Although surface warm front will continue to lift north ahead of the
   short wave, much of central MN will struggle to destabilize due to
   significant ongoing convection. As a result, primary area of
   strong/locally severe convection should remain focused from extreme
   southeast ND/eastern SD into southwestern MN. Over the next several
   hours this activity will gradually stabilize/overturn instability
   currently observed across this region. Marginally severe hail and
   locally damaging winds remain the main risks.
