...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS
OF EASTERN WA...
...SUMMARY...
Scattered severe thunderstorms, offering destructive winds and hail,
are expected to continue through roughly 10 PM PDT over parts of the
interior Pacific Northwest, east of the Cascades.
...Pacific Northwest...
Earlier thinking, regarding the development of an MCS east of the
Cascades, remains. Latest radar data suggests several thunderstorm
clusters have evolved into a complex of storms over southern WA.
This activity is being aided by the exit region of a strong upper
jet that is translating into the northern Rockies. Latest diagnostic
data suggests ample buoyancy resides across eastern WA into western
MT for the maintenance of ongoing MCS as it propagates toward
southeast BC. Current speed/movement of this complex suggests the
back edge should approach the international border by 05z.
