...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS
OF THE CENTRAL HIGH PLAINS...

...SUMMARY...
Isolated severe storms capable of damaging wind will be possible the
central High Plains on Thursday.

...Synopsis...
A weak mid-level shortwave trough will move through the flow across
the central High Plains within the region between the amplified
western ridge and eastern trough Thursday afternoon. At the surface,
weak low pressure will develop across the Oklahoma/Texas Panhandles
with a stationary front/boundary in place from eastern Colorado into
the southern Plains. Thunderstorm development is likely across the
Front Range in Colorado, with an increase in coverage spreading into
the lower plains with the influence of the passing shortwave.

...Central High Plains...
Southerly to southeasterly flow across the southern/central High
Plains will bring moisture northward into portions of the
Oklahoma/Texas Panhandles and into western Kansas/eastern Colorado.
This in combination with steep mid-level lapse rates and heating
will yield a moderately unstable air mass from eastern Colorado into
western Kansas by the afternoon. Initially, storms are expected to
develop along the Front Range before moving into the lower plains
and western Kansas by the evening. Shear profiles across Colorado
will be fairly weak tempering severe potential. Nonetheless, deeply
mixed profiles may support some strong to severe outflow gusts. As
the shortwave shifts southward through the period, mid-level flow
will increase across western Kansas with resulting modest deep layer
shear increase. As storms/clusters move east through the late
afternoon/evening an organized cluster or two will have the
potential to produce damaging wind.
