...Synopsis...
Regional fire weather concerns will persist for parts of the
northern Sierra Nevada/southern Cascades for Wednesday. Persistent
troughing across the northeastern Pacific, juxtaposed with a
dominant upper ridge over the Great Basin, will maintain a belt of
modest mid-level flow over the Northwest. co*bined with antecedent
hot/dry conditions, these winds will result in areas of elevated
fire weather conditions. Elsewhere across the northern Rockies and
Plains, dry conditions will prevail, but weak surface winds will
limit further concerns.
...Northern Sierra Nevada and southern Cascades...
Mostly clear skies will facilitate strong diurnal heating and deep
boundary-layer mixing by early afternoon across northern CA into OR
and northern NV. Coupled with antecedent dry conditions,
temperatures in the mid 90s will drive RH values into the low teens.
Downward transfer of stronger mid-level flow will help support winds
between 15-20 mph, especially in the vicinity of terrain features.
While some deterministic solutions hint at only localized elevated
conditions, a strong signal in hi-res ensemble guidance lends enough
confidence to introduce a risk area.
