...Northwest...
On Day 4/Wednesday, the northern periphery of a large-scale ridge
centered over the Great Basin will break down, as a belt of moderate
midlevel west-southwesterly flow overspreads the Northwest. This
will promote an increase in westerly surface winds along/east of the
Cascades (especially in the Columbia Basin) -- where hot/dry
conditions will remain in place. Elevated to locally critical
conditions are expected, though sustained critical conditions may
remain localized to the Cascade gaps (e.g., the Columbia Gorge) --
precluding 70-percent Critical probabilities at this time.

The strengthening midlevel flow along the northern periphery of the
ridge may continue to promote dry/breezy conditions across the
Northwest (including northern CA into southern ID) through the
remainder of the extended forecast period. However, confidence in
any more than locally critical conditions is too low to add
additional probabilities.

Additionally, thunderstorm potential may increase across parts of
the Northwest late in the extended forecast period (i.e., Days
7-8/Saturday-Sunday), as a midlevel moisture plume spreads northward
along the western portion of the eastward-shifting large-scale
ridge. Confidence in thunderstorm development is too low to add Dry
Thunderstorm probabilities right now, though this scenario will be
monitored closely.

...Central/Southern CA...
An enhanced onshore pressure gradient will continue to support hot,
dry, and locally breezy conditions primarily across inland portions
of central and southern CA through the period. While this will favor
elevated to locally critical conditions, the threat appears too
localized for probabilities.
