Mesoscale Discussion 1703

Areas affected...portions of far northern Utah into southeast Idaho

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

Valid 250055Z - 250200Z

Probability of Watch Issuance...20 percent

SUMMARY...A focused, localized severe gust threat may accompany a
small bow echo for a couple more hours. Given the localized severe
threat, a WW issuance is not expected.

DISCUSSION...A small, compact multicellular cluster of storms has
recently demonstrated bow-echo characteristics across northwestern
UT, where multiple damaging gusts and a 65 kt measurement have been
reported. Interrogation of regional radar shows that a rear-inflow
jet likely accompanies this bow echo, suggesting efficient severe
wind potential. 00Z mesoanalysis shows 9 C/km boundary layer lapse
rates preceding the bow echo, indicative of an ambient environment
that would support more severe gusts. While potentially
concentrated, the severe threat should remain quite localized,
precluding the need of a Severe Thunderstorm Watch.
