Areas affected...Eastern Colorado to northeast New Mexico and
northwest Kansas

Concerning...Severe potential...Watch possible

Valid 101943Z - 102145Z

Probability of Watch Issuance...60 percent

SUMMARY...Thunderstorms moving off the Rockies will be capable of
severe downburst winds from eastern Colorado into northeast New
Mexico and northwest Kansas. Thunderstorm coverage is expected to be
relatively higher across CO, and may require watch issuance in the
short-term.

DISCUSSION...Thunderstorm coverage has slowly increased over the
past 1-2 hours across central CO. Observed dewpoint depressions on
the order of 40-50 F hint that very deep/dry boundary layers are in
place east of the Front Range across the High Plains. While buoyancy
is fairly limited (MLCAPE around 250-500 J/kg), LCLs between 3-4 km
will favor very strong downdraft accelerations via evaporative
cooling. Severe downburst winds have already been observed with more
isolated convection earlier today, and velocity imagery from KFTG is
showing 40-50 knot low-level outflow winds associated with stronger
convective cores. The potential for severe winds should increase in
tandem with convective coverage through the late afternoon hours
when diurnal heating/mixing will be maximized. Expanding cold pools
coupled with 25-35 knot 0-6 km bulk shear may support the
development of one or more organized clusters that could pose a more
robust wind threat with gusts potentially as high as 80 mph. In
general, thunderstorm coverage should remain greatest across CO due
to ascent associated with a passing mid-level wave and weak cold
front, though more isolated severe storms are possible further south
into northeast NM. Watch issuance is probable for portions of the
region as thunderstorm coverage (and the severe wind threat)
increases.
