Areas affected...portions of southern/central Idaho and southwestern
Montana

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

Valid 312034Z - 312130Z

Probability of Watch Issuance...20 percent

SUMMARY...Potential for strong to severe winds with thunderstorm
activity this afternoon and evening.

DISCUSSION...Thunderstorm activity has developed across portions of
southern Idaho near the Snake River Plain and Sawtooth Range. This
is expected to continue to move northward this afternoon, with
potential for strong to severe winds. Temperatures across
southern/central Idaho are in the mid to upper 80s, with large dew
point spreads around 40 degrees noted in surface observations.
Surface objective analysis shows steep low to mid-level lapse rates
around 8.5-9 C/km. This environment will be supportive of strong
downburst potential. As storms cluster and grow along outflow, a
more organized damaging wind threat may emerge.
