.SYNOPSIS...
A prolonged period of above normal temperatures will continue
through the middle of next week. Conditions will be mostly dry.
Winds will be gusty Sunday, especially in Central Washington.

&&

.DISCUSSION...
Today through Tuesday: A warming trend is coming for the Inland
Northwest through Tuesday as upper level ridging builds.
Temperatures will warm around 5-10 degrees Saturday (upper 70s
to mid 80s) in central WA as the ridge axis crosses the
Cascades. Further east, temperatures will still warm around 1-3
degrees with temperatures in the 70s. Winds will be light and
terrain driven Saturday.

A shortwave trough will translate through the mid level ridge
Sunday, bringing a warming trend around 5-10 degrees for eastern
WA and north ID. An associated dry cold front will cross the
Cascades in the afternoon Sunday and reach eastern WA and north
Idaho around sunset, ushering in dry air and breezy conditions
in central WA. Winds will be northwest sustained 15-25 mph with
gusts up to 40 mph, increasing grass fire risk. Patchy blowing
dust is possible on the Waterville Plateau and western Columbia
Basin Sunday evening.

There is high confidence of a high amplitude ridge building in
behind this front passage bringing a warming trend into Tuesday.
By Tuesday, there is high confidence for temperatures to be in
the 80s to low 90s. There is a 15-45% chance for the lower
elevations of the Okanogan Valley, Columbia Basin, L-C valley,
and Wenatchee River valley to see the first 90 degree readings
of the spring Tuesday.

Wednesday through Saturday: The forecast starts to diverge
amongst the ensembles Wednesday as a trough in the Pacific will
seemingly do one of two things. First scenario (65% chance)
involves the low pressure staying near the northern California
coast, which would keep very warm temperatures in the upper 70s
to upper 80s in the region Wednesday. The other scenario (35%
chance) involves a trough in closer proximity to the region,
which would bring cooler temperatures in the 60s and 70s and
chances for mountain showers. Evening AI guidance from the EPS-
AIFS and AIGFS ensembles suggest scenario one is more likely
with renewed warmth Wednesday and possibily even Thursday. There
is good agreement for unsettled weather and a cooldown Friday
and Saturday as a deeper trough lingers in the Gulf of Alaska
bringing temperatures into the 60s and 70s. This would bring
temperatures closer to normal for mid May in the region. /DB
