   Areas affected...Eastern Upper Michigan into northern Lower

   Concerning...Severe Thunderstorm Watch 314...

   Valid 111946Z - 112145Z

   The severe weather threat for Severe Thunderstorm Watch 314

   SUMMARY...A threat of damaging winds continues across the watch

   DISCUSSION...A long-lived convective system is now crossing over
   northern Lake Michigan, with sporadic cellular development just
   ahead of it near the northern coast. This line of storms has a long
   history of producing wind damage. 

   While instability levels decrease to the east, surface observations
   and satellite imagery show warming continues across much of Lower
   Michigan, with temperatures rising into the mid 80s along with weak
   pressure falls. In addition, southerly low-level flow continues to
   increase ahead of the MCS. Therefore, while the line may not be as
   strong as it was previously, conditions may prove sufficient for a
   continued localized damaging wind threat.
