   The severe weather threat for Severe Thunderstorm Watch 491
   continues.

   SUMMARY...Strong-severe thunderstorms will propagate southeast
   across ww491. Damaging winds are the primary concern.

   DISCUSSION...A very weak short-wave trough appears to have crested
   the ridge and is digging southeast across the central High Plains
   late this evening. Scattered robust convection has gradually
   coalesced into a linear MCS which currently extends from
   northwestern KS into extreme eastern CO. A narrow axis of modest
   instability is noted across southwest KS, along and north of a
   boundary that stretches across the OK Panhandle into far southeast
   CO. This boundary is being reinforced a bit by scattered convection
   along the KS/OK border into northwest OK. Net result will likely be
   for the ongoing MCS to continue tracking southeast, aided in part by
   southeasterly low-level inflow. 56kt gust was reported at GLD with
   the squall line, and this type of wind may continue to be reported
   as the MCS propagates toward southwestern KS over the next several
   hours.
