Areas affected...Eastern Idaho...Western Wyoming...Northern Utah

Concerning...Severe potential...Watch unlikely=20

Valid 132148Z - 140015Z

Probability of Watch Issuance...5 percent

SUMMARY...An isolated severe threat will likely continue for a few
more hours. Hail and gusty winds will be the primary threats. The
severe threats should remain too marginal for weather watch issuance
is not expected.

DISCUSSION...The latest water-vapor imagery and 500 mb RAP analysis
suggest that a shortwave trough is moving through the northern
Rockies. Lift associated with this feature, is supporting scattered thunderstorm development near a pocket of moderate instability from
northern Utah into eastern Idaho. MLCAPE within this area is
estimated by the RAP to be in the 1000 to 1500 J/kg range. Mid-level
lapse rates are also steep. In addition, the latest WSR-88D at
Pocatello, Idaho has 0-6 km shear around 35 knots, with speed shear
mostly in the mid-levels. This should be enough for locally strong
to severe convection. A rotating storm or two will be possible with
hail and gusty winds as the primary threats. The marginal severe
threat may persist into the early evening.
