   Areas affected...north central through west central Minnesota

   Concerning...Severe Thunderstorm Watch 537...

   Valid 040204Z - 040400Z

   The severe weather threat for Severe Thunderstorm Watch 537
   continues.

   SUMMARY...Stronger storms, mainly those initially forming along the
   eastward advancing cold front, may continue to briefly pose a risk
   for severe weather into the 10 PM-midnight time frame.

   DISCUSSION...The surface frontal zone now appears to be in the
   process of advancing eastward, with 2-4 mb 2-hourly surface pressure
   rises recorded in 01Z observations west of Bemidji MN through
   Wahpeton ND and north through west of Watertown SD.  This appears to
   be occurring in the wake of a developing surface frontal wave which
   likely will overspread the International Falls area (where 2 hourly
   falls on the order of 2 mb are evident near and to its southwest)
   within the next few hours.

   Thunderstorm activity does continue to increase along and to the
   cool side of the front, with initial stronger storms developing
   along the front likely to continue to be quickly undercut.  But
   these could still briefly pose a risk for damaging wind gusts and
   perhaps a brief tornado, in addition to large hail, into the 03-05Z
   time frame.
