   Areas affected...Eastern Oklahoma far southern Mississippi...and
   northwest Arkansas

   Concerning...Severe Thunderstorm Watch 375...

   Valid 061246Z - 061415Z

   The severe weather threat for Severe Thunderstorm Watch 375
   continues.

   SUMMARY...A damaging wind/tornado threat should persist for a few
   more hours.

   DISCUSSION...A line of storms continues to produce sporadic
   damaging/severe wind gusts with occasional mesovorticies and line
   embedded tornadoes. Only around 1000 to 1500 J/kg MUCAPE exists
   ahead of the line now. In addition, a 40 knot low-level jet which
   helped to maintain the MCS through the overnight period remains
   across eastern Oklahoma and far western Arkansas with a weaker
   low-level jet across central Arkansas and southern Missouri.
   Therefore, as storms continue to move east of the stronger low-level
   jet and the low-level jet weakens through the morning, expect this
   line of storms to weaken within the weak to moderately unstable
   environment.

   In the meantime, a 35 knot low-level jet from the KSRX VWP and >200
   m2/s2 will continue to support a severe wind/embedded tornado threat
   in the near term before this weakening becomes more prevalent by
   mid-morning.
