Areas affected...portions of southeastern Idaho into southwest
Montana

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

Valid 012031Z - 012200Z

Probability of Watch Issuance...5 percent

SUMMARY...Isolated damaging wind gusts possible this
afternoon/evening.

DISCUSSION...Visible satellite/radar shows a few areas of convection
that have developed during peak heating, mostly confined to high
terrain areas. This activity is developing in a relatively dry
boundary layer characterized by dew point temperatures in the 40s F.
Yet, strong heating has yielded strong low-level lapse rates,
exceeding 9 C/km in most areas, and inverted-V profiles. Thus,
strong downdraft winds are likely with any convective elements
throughout the remainder of the afternoon and into the evening as
the activity gradually moves off high terrain areas. However, given
the expectation for somewhat sparse coverage of storms, watch
issuance is unlikely.
