.SYNOPSIS...
A relatively quiet early summer weather pattern is expected for
the remainder of the week and into the weekend. Afternoon
temperatures today, Wednesday and Thursday will be in the 80s.
A two-day warm up is expected Friday and Saturday with highs in
the upper 80s to mid 90s. A weak cold front on Saturday will
likely push temperatures back down closer to average for the
beginning of next week.

.DISCUSSION...
Today and Wednesday: A cold front will push through the region
this morning ushering drier air in from northwest. Lingering
showers and isolated thunderstorms over SE WA and lower Idaho
Panhandle noted on the 2AM radar imagery will continue to depart
to the east with dry and sunny weather expected. The only
potential for a busted forecast would come around the Camas
Prairie if the drier air is slower to arrive. In this event, we
may build up enough instability prior to noon for an isolated
shower or thunderstorm. Steady winds around 10 mph are expected
with occasional gusts in the 15-20 mph range. Temperatures will
be cooler only topping out in the 80s. A wave drops in from the
north on Wednesday bringing some cloud cover and small chance for
isolated convection across the NE mountains. The antecedent air
mass will be dry and this will make it tough for showers and
thunderstorms to develop so general confidence levels remain low
and forecast leans toward the drier GFS solutions. 80s continues
on Wednesday with over trends 1-3 degrees cooler than Tuesday. /sb

Thursday and Friday: A shortwave high pressure ridge will expand
over the Pacific Northwest Thu and Fri. Look for light winds and
warming trend. High temps should be in the 80s Thu and upper 80s
to mid 90s Friday.

Saturday: There is good model agreement that the late week high
pressure ridge will be flattened late Friday night into Saturday.
The incoming weak trough is expected to push a cold front across
the Cascades Saturday. A slight chance of afternoon/evening
thunderstorms has been retained along the Canadian border, but
low and mid level moisture will limit coverage to widely scattered
at best. The front is expected to shave 3 to 5 degrees off high
temps Sat compared to Fri. West or southwest winds of 10 to 15 mph
are advertised by the GFS and ECMWF Sat afternoon with gap winds
in the lee of the Cascades gusting up to 25 mph Sat evening.

Sunday through Tuesday: Models are in fairly good agreement
bringing a low with attendant cold front into BC during this
period leaving us in either zonal or SW flow under its base. As
far as sensible weather, look for fairly benign conditions with
plenty of sunshine and temperatures starting out a few degrees
above normal for Sunday, cooling back closer to seasonal normals
by the 4th of July holiday. /Kalin
