Areas affected...Central High Plains

Concerning...Severe Thunderstorm Watch 611...

Valid 072330Z - 080130Z

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.
