...Synopsis...
Dry thunderstorms will be the primary fire weather concern for
today. Isolated dry thunderstorms were observed yesterday (Saturday)
across portions of central NV on the fringe of a modest monsoonal
moisture plume. This air mass is currently advecting northward into
north-central NV and adjacent portions of OR/ID per latest
water-vapor imagery. 00z soundings along the West Coast have already
begun to sample this mid-level moisture as well as cool mid-level
temperatures, which should support MUCAPE values between 100-250
J/kg this afternoon. Concurrently, an upper wave off the northern CA
coast is forecast to move onshore over the next 24-48 hours. Lift
ahead of this wave will overspread the moisture plume, resulting in
isolated to widely scattered thunderstorms from central OR into
eastern NV/far western UT. Dry boundary layer conditions (as well as
fast storm motions across OR) will limit rainfall accumulation and
favor dry lightning strikes. Given regional ERCs at or above the
80th percentile, dry lightning will pose a fire weather concern.

Elsewhere across the West, dry conditions will prevail with another
day of afternoon RH minimums in the teens expected. Strengthening
southerly mid-level winds may support areas of dry/windy conditions
in the immediate lee of the central and northern Sierra Nevada, but
such conditions should remain too limited to warrant highlights.
