- Gusty winds and dry conditions Tuesday. Elevated grass fire

.SYNOPSIS...
Warm and dry conditions will continue through Monday.
Temperatures will warm above normal with highs in the upper 60s
to the low 70s into Monday. Temperatures cool back to near
normal Tuesday with a dry cold front passage. The Inland
Northwest looks to be unseasonably dry through the next week.

&&

.DISCUSSION...
Today through Monday: A ridge of high pressure will continue to
strength over the area. This will bring dry, warm weather.
Higher clouds, however, will spread across the area leading to
some partly sunny to mostly conditons just for those high
clouds. Highs will in the upper 60s and 70s today and 70s and
low 80s Monday. Overnight lows will be in the upper 30s and low
40s. The ridge begins breakdown Monday with a trough approaching
from Canada. This will start to bring in breezy/gusty winds
Monday afternoon into Monday night. Gusts in the 15-25 mph are
forecast, strongest near the Cascades/central WA.

Tuesday: The trough will push a strong dry cold front through
the area. Ahead of the front early in the day, precipitable
water values are around 130-140 percent of normal. The primary
precipitaiton chances will be over the Cascades and northern
mountains and that will be light. As we head into the later
morning and afternoon, the drier air pushes in with PWATs
dropping to 45-75% of normal. The front and mixing with it will
provide gusty winds. Guidance shows sustained winds in the 15-30
mph range, with gusts between 30-40 mph, locally near 50 around
the Blue Mountains. The strongest are forecast around the
Okanogan Valley (especially early) and also around the Columbia
Basin and Palouse into the Blues. The dry, breezy conditions
lead to some early season fire concerns for dry grasses and
shrubs in the Basin. Tuesday`s highs will be about 10-15 degrees
cooler than Monday, reaching the 50s to mid-60s.

Wednesday to Saturday: High pressure will build off the Pacific
Northwest coast and bring another period of dry weather until
perhaps later Saturday into Sunday. Ensembles continue to show a
less the 10 percent chance of precip through Friday. Then
heading into Saturday (and next Sunday) the ridge is forecast to
break as Gulf of Alaska Low drops in. This will increase precip
chances, with the best risk around the mountain zones,
expanding out more across the eastern third of WA Saturday night
(into next Sunday). Highs will be in the mid 50s to low 60s
Wednesday, warming into the 60s and low 70s by Friday. Lows will
be in the 30s and low 40s. /Solveig
