Synopsis...
a warming and drying trend will commence today and culminate in a
return to hot and dry Summer conditions through the next week.

Discussion...
today to saturday: benign conditions accompany the start of a
warming trend. Today the inland northwest will be in a zonal flow. An
upper wave rounding the Gulf of Alaska trough pushes onshore late,
largely north of the British Columbia border, weakening as it does so. With no
significant moisture or instability, aside from some increased
lapse rates in the low levels with the afternoon heating, look for
dry weather. Some clouds will linger across the Cascade crest and
northeast Washington/north Idaho early. Otherwise look for some thin high
clouds and few flat cumulus near the mountains in the afternoon. A
diurnal increase in winds is projected, but overall speeds are
expected to be under 15 mph. Tonight into Saturday the Gulf of Alaska
low digs south and as a result a ridge begins amplifying over the
inland northwest. This will mean even less cloud cover, less wind and dry
weather. With a cool low exiting temperatures will begin to
moderate, though today's values will still remain several degrees
under seasonal averages. By Saturday the increasing southwest flow
and amplifying ridge will allow temperatures to push back closer
to average. /J. Cote'

Saturday night through Wednesday...very good model agreement
and run to run consistency exists through the extended term. A
strengthening 4 corners high pressure will build through early
next week and stabilize by the middle of the week. This will
promote a strong surface thermal trough over the Columbia Basin
for a general increase in temperature each day culminating in hot
and dry conditions through the upcoming week. The only potential
threats during this period will impact fire weather concerns
including elevated Cascade Gap winds during the evening
hours...and a ghost of a chance of some monsoonal moisture
sneaking into the Blue Mountains and Idaho Panhandle by next week.
The monsoonal Prospect is ill defined and low confidence at this
time. Condensing the preceding 122 words yields "increasingly hot
and dry". /Fugazzi

Aviation...
12z tafs: high pressure starts to build in over the next 24 hrs,
leading to dry, VFR conditions at taf sites, with diurnal winds
with speeds peaking in the afternoon near 10 to 15 kts. /J. Cote'
