Areas affected...Southwest NE Panhandle vicinity

Concerning...Severe potential...Watch unlikely

Valid 110010Z - 110145Z

Probability of Watch Issuance...5 percent

SUMMARY...A couple hours of severe hail and wind are possible with a
pair of slow-moving supercells before convection weakens after dusk.

DISCUSSION...Convection near the WY/NE border has consolidated into
a pair of nearly stationary supercells. This recent organization
appears to be in response to some strengthening of both mid-level
west-southwesterlies and low-level southerlies in CYS VWP data. The
latter has also supported an influx of 50-54 F surface dew points,
which has aided in the supercell intensification. However, this will
likely be transient/short-lived, similar to how convection had
pulsed up and weaken along the south slope of the Black Hills in far
southwest SD. Onset of nocturnal boundary-layer cooling and large
surface temperature/dew point spreads should foster
outflow-dominated cells that have pronounced weakening after dusk.
