0431 PM CDT Wed Apr 03 2024

Areas affected...portions of far eastern Oregon into western and
central Idaho

Concerning...Severe potential...Watch unlikely 

Valid 032131Z - 032300Z

Probability of Watch Issuance...5 percent

SUMMARY...Isolated strong wind gusts and instances of hail may
accompany the stronger storms this afternoon into early evening. The
severe threat is expected to be sparse and localized.

DISCUSSION...Multiple pulse cellular storms and multicells have
recently developed to the east of a cloud deck in the past couple of
hours over far eastern OR into southwestern ID. Here, diurnal
heating has encouraged surface temperatures to warm into the mid 60s
F amid mid 30s-40s F dewpoints, that in tandem with steep lapse
rates, has boosted SBCAPE to 500-1000 J/kg. RAP forecast soundings
and regional VADs depict curved, elongated hodographs, indicating
the presence of strong deep-layer shear, with 21Z mesoanalysis
depicting over 40 kts of effective bulk shear. Forecast soundings
show thin CAPE profiles atop a dry, well-mixed boundary layer. As
such, brief and localized instances of strong wind gusts and perhaps
some hail may occur with the stronger multicells or any transient
supercells that can develop. Nonetheless, the severe threat is
expected to remain isolated.
