   Areas affected...Northern Oklahoma

   Concerning...Severe Thunderstorm Watch 442...

   Valid 160228Z - 160400Z

   The severe weather threat for Severe Thunderstorm Watch 442
   continues.

   SUMMARY...Isolated strong/severe thunderstorms will move west across
   northern Oklahoma over the next few hours. Some hail and wind remain
   possible.

   DISCUSSION...Small cluster of thunderstorms that developed over
   southwest MO earlier this afternoon have propagated west-southwest
   over the last few hours, and continue at roughly 20 kt. Despite the
   lack of large-scale forcing, these updrafts have largely continued
   due to moisture/strong buoyancy observed across northern OK.
   However, over the last hour or so it appears updraft intensity has
   weakened considerably. Given these trends, marginally severe hail
   and winds generally less than 50 mph may be noted with this small
   cluster as it spreads toward the western edge of ww442 by 04z.
