.PREV DISCUSSION... /issued 126 PM PDT Thu Jul 10 2025/

SHORT TERM...Today through Saturday...Breezy conditions prevail
through the Cascade Gaps and into the Basin this afternoon in the
wake of an upper-level trough that brought stronger winds to the
forecast area last night. Once this system is out of our area of
influence, a dry and hot pattern will take hold through at least the
midweek next week. Until then, expect relatively seasonable
temperature readings, with the heat initially starting to ramp up on
Saturday.

RHs will drop off over the weekend as a result of this building
heat, stemming from a broad ridge building over the PacNW, but this
ridge will help even out pressure gradients, keeping winds primarily
thermally-induced through the Cascade Gaps. The expectation,
however, is that winds will not be strong enough to cause critical
fire weather conditions, at least in the short term. Evans/74

LONG TERM...Sunday through Thursday...Heat continues through the
first half of next work week, with temps expecting to peak on Sunday
with highs over 100 across much of the Basin, before deterministic
guidance depicts a shortwave clipping us to our northeast on
Tuesday. While this system is not anticipated to bring us any rain,
it will remain significant for firefighting efforts in the sense
that it will bring about a distinct wind change to the north and
northeast after days of more typical westerly flow. Models as of now
are not projecting particularly strong winds, but any distinct wind
shift, especially toward the east, can greatly hinder firefighting
coordination.

Ensembles are a bit divided over what occurs synoptically Wednesday
onward, but the general consensus appears to lean toward that of a
progressive and relatively zonal pattern. Clustering, however, does
not provide enough detail to go too much into detail on how the
forecast is expected to evolve beyond the midweek next week, other
than to at the very least expect a continuation of above-normal
temperatures, breeziness through the Cascade Gaps, and little to no
rain threats for the time being. Evans/74
