The severe weather threat for Severe Thunderstorm Watch 588

SUMMARY…Storms/severe risk continue to gradually increase across
the WW area.

DISCUSSION…The latest radar loop over the central High Plains
vicinity shows a couple of strong/likely severe storms over Lincoln
county, in southwestern portions of WW 588, moving southeastward.
New/intense cells have developed quickly across northeast Colorado
over the past half hour, while still farther north/northwest, a
convective increase is noted over the southeast Wyoming vicinity.

Severe risk continues across the watch area, where an axis of strong
instability — aided by a southeasterly influx of low-level moisture
— is indicated. Very large hail remains possible, along with
locally damaging winds.

With time, storms are expected to spread — or redevelop — eastward
into more of Kansas and Nebraska, as a low-level jet intensifies
this evening. We will continue to monitor convective evolution,
with a new watch/watches anticipated east of the existing WW, during
the evening.
