   The severe weather threat for Severe Thunderstorm Watch 611
   continues.

   SUMMARY...Hail and wind threat will spread east with convection this
   evening.

   DISCUSSION...Water-vapor imagery suggests a weak disturbance may be
   encouraging upscale convective growth over the central High Plains
   early this evening. Upper anticyclone remains positioned over the
   Great Basin and northwesterly 500mb flow should strengthen a bit
   over northeast CO into western NE tonight. Scattered robust
   convection is gradually increasing in areal coverage as it
   propagates downstream into somewhat more buoyant airmass, especially
   along/south of the synoptic front that currently extends across the
   NE Panhandle into southeast WY. Prefrontal wind shift is also aiding
   convection across northeast CO and this activity should gradually
   advance toward northwest KS later this evening. Several supercells
   are noted within the larger convective complex, but mixed storm mode
   should linger for several hours before possible MCS evolves over
   northeast CO/southwest NE after sunset.
