   Areas affected...South-central KS and northwest OK

   Concerning...Severe Thunderstorm Watch 383...384...

   Valid 031014Z - 031115Z

   The severe weather threat for Severe Thunderstorm Watch 383, 384

   SUMMARY...A swath of 65-80 mph wind gusts is likely ongoing across a
   portion of south-central Kansas and should spread into parts of
   northwest Oklahoma through mid-morning.

   DISCUSSION...A 200-km long QLCS is ongoing across a part of
   southwest/south-central KS into far northwest OK. This QLCS has
   matured over the past couple hours with a history of measured severe
   wind gusts to 74 mph thus far. Strongest velocities have been noted
   within the apex of the line that has now shifted south of the US-54
   corridor. Time-series of Vance AFB VWP has indicated some weakening
   of the south-southwesterly low-level jet, but it is still holding in
   the low 40s kts. While this leading wind surge may be tempered in
   time as it spreads into a more marginally unstable air mass farther
   east in south-central KS, an additional swath may develop along the
   trailing flank along the pronounced MLCAPE gradient in northwest OK.
