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. ...Broyles/Edwards.. 08/13/2024 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!_dW4wi2ZvN_YzKkrcUYX_lXcg24L6GBptdY3JEuvZH3_SgxRVhnQ46d-LpvJ6HPdYE2w4e5UZ= ew6ZgffJ5RLiYqOFDs$ for graphic product...
