Areas affected...Utah

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

Valid 252004Z - 252200Z

Probability of Watch Issuance...20 percent

SUMMARY...Severe downburst winds will be possible through early
evening. However, this threat should be sufficiently scattered to
preclude watch issuance.

DISCUSSION...Regional radar and GOES IR imagery depicts steady
strengthening of convection across eastern NV into central and
northwest UT. Concurrently, mostly clear skies and strong diurnal
heating downstream has allowed for temperatures to climb into the
upper 80s and low 90s, which has nearly eliminated MLCIN based on
the 18 UTC SLC sounding. This RAOB also depicted a fairly dry
boundary layer with 0-3 km lapse rates of nearly 9 C/km that will be
favorable for downdraft accelerations and strong to severe downburst
winds. Consequently, the potential for severe wind gusts should
increase over the next few hours as developing convection continues
to intensify and spreads east/northeast through early evening.
Latest time-lagged ensemble guidance appears to be capturing current
convective trends well and suggests that convective coverage should
remain sufficiently isolated to preclude watch issuance, but gusts
up to 60-70 mph appear possible with the strongest storms.
