Areas affected...Portions of northern NV/UT into southern ID
Concerning...Severe potential...Watch unlikely=20
Valid 071922Z - 072145Z
Probability of Watch Issuance...5 percent
SUMMARY...Isolated strong to severe wind gusts may occur this
afternoon with high-based thunderstorms. Watch issuance is unlikely.
DISCUSSION...Thunderstorms have developed this afternoon across
parts of northeast NV into western UT, as a shortwave trough
continues to move eastward across CA/NV. Robust daytime heating has
allowed surface temperatures to generally increase into the 80s.
Amid steepening low/mid-level lapse rates, a well-mixed boundary
layer should encourage some enhancement to convective downdraft
winds as DCAPE increases into the 1000-1500 J/kg range. Isolated
strong to severe wind gusts around 50-70 mph may occur with any of
the more robust cores that can develop and be sustained this
afternoon and early evening. Occasional marginally severe hail also
appears possible, with around 30-35 kt of deep-layer shear
supporting modest updraft organization. Limited instability and
low-level moisture, with MLCAPE generally forecast to remain less
than 1000 J/kg, should tend to temper the overall severe threat.
Accordingly, watch issuance is not anticipated.
