Areas affected...eastern Colorado...portions of western Kansas

Concerning...Severe potential...Tornado Watch likely

Valid 061839Z - 062015Z

Probability of Watch Issuance...80 percent

SUMMARY...Supercells capable of large to very large hail, damaging
wind, and a couple of tornadoes likely later this afternoon.

DISCUSSION...Visible satellite shows deepening cu along the Front
Range in Colorado over the last hour, with a few lightning flashes
near the Denver metro. CAM guidance suggests additional thunderstorm
development is likely across the Front Range into eastern Colorado
over the next 1-2 hours. Some MLCIN remains across portions of
southeastern Colorado but warming temperatures have climbed into the
70s, nearing convective temperature in morning forecast soundings.

The profiles within this region are characterized by linear and
elongated hodographs, with strong deep layer shear around 45-55 kts
(strongest across southeastern Colorado. While moisture is modest,
with MLCAPE around 500 J/kg, strong deep layer shear should aid in
organized supercells capable of large to very large hail. Given the
linear hodograph profiles, splitting supercells will favored.
Low-level shear is marginal (0-1 SRH around 50-100 m2/s2) but storm
interactions and interactions with terrain may lead to locally
increased SRH and potential for a tornado or two. Clustering cells
may lead to an increasing damaging wind threat as the
afternoon/evening progresses. A Tornado Watch will likely be needed
in the next hour to cover these threats.
