   Areas affected...East-central Colorado into west-central Kansas

   Concerning...Severe Thunderstorm Watch 398...399...

   Valid 090117Z - 090315Z

   The severe weather threat for Severe Thunderstorm Watch 398, 399
   continues.

   SUMMARY...A swath of 80-95 mph gusts could continue for a few more
   hours with an organized thunderstorm cluster tracking
   east-southeastward across east-central Colorado into west-central
   Kansas.

   DISCUSSION...KGLD radar data shows an organized/upscale-growing
   bowing line segment (with organizing MCV and rear-inflow jet)
   tracking southeastward at around 30 kt across east-central
   CO/west-central KS immediately south of I-70. A gust of 96 mph was
   measured in Burlington CO with this activity, with more frequent
   gusts of 60-70 mph. The KGLD VWP depicts a large, clockwise-curved
   hodograph with around 60 kt of 0-6 km shear orthogonal to the gust
   front of the storm. This, combined with upper 50s/lower 60s
   dewpoints beneath steep midlevel lapse rates, should support the
   maintenance of this intense cluster as it continues
   east-southeastward during the next few hours.
