   Areas affected...parts of central into eastern North Dakota

   Concerning...Severe Thunderstorm Watch 409...

   Valid 280455Z - 280700Z

   The severe weather threat for Severe Thunderstorm Watch 409
   continues.

   SUMMARY...Trends will continue to be monitored, but a new severe
   weather watch probably will not be needed to the east of severe
   weather watch 409.

   DISCUSSION...Two-hourly surface pressure rises on the order of 2-6
   mb were still evident within the eastward propagating cold pools
   overspreading central North Dakota in the 04Z surface observations. 
   However, further cooling and some drying of the boundary-layer has
   been evident in observations across eastern North Dakota, where
   southerly flow around 850 mb is also forecast to gradually weaken
   overnight ahead of the remnant convective system.  Less unstable and
   weakening updraft inflow seem likely to contribute to sufficient
   further weakening of storms that a new severe weather watch may not
   be needed to the east of the current watch.
