302 AM PDT Fri Apr 21 2017
High pressure overhead into Saturday will bring drier and much
warmer afternoon conditions. A couple of weak systems will brush
by to the north Saturday and then Sunday with increasing winds and
periods of clouds. Additional systems will bring breezy conditions
with periods of precipitation next week. Temperatures will ease
down to near or slightly below average next week.
A ridge over northeast CA and western NV will bring lighter winds,
dry conditions, and a warming trend. Light low-level easterly
flow will remain in place today with high pressure centered over
eastern Oregon and western Idaho. This will slightly limit the
warming potential with highs around average today.
The ridge begins to flatten Saturday in response to a trough pushing
into the Pacific Northwest, but there will also be better mixing
as southwest flow aloft increases. This will make Saturday the
warmest day of the week, with high temperatures peaking out 8-12
degrees above normal. High clouds will be on the increase later in
the day, with breezy afternoon winds developing as cooler air
over northern California increases thermal gradients across the
Another weak system brushes through the Pacific Northwest on Sunday,
bringing some cooling to the eastern Sierra and western Nevada
with a few light showers possible near the Oregon border.
.LONG TERM...Monday through Friday...
Few changes made to the long term forecast with a general cool,
moist west to northwest flow into the West Coast. The EC and GFS
are coming into better agreement trying to target late Tuesday
into Tuesday night with the bulk of the moisture and lift.
Increased the threat of rain and mountain snow during this time,
but made few changes outside of that.
The moist flow begins Monday into Tuesday, but it appears the best
moisture and lift will remain over Washington and Oregon. Winds will
be a bit gusty with peak gusts around 40 mph possible both
afternoons, then a better chance into Tuesday night as a stronger
short wave pushes a cold front through. Afterward, the cool, moist
flow will continue but the best forcing retreats north and east
once again. Winds could be gusty those days as well with temperatures
on average a little below normal for next week. Wallmann
VFR conditions with light winds into Saturday morning. Some gustier
winds possible Saturday afternoon from the SW with peak gusts to 25
kts. More gusty winds likely on Sunday with a cooler, moister
pattern expected next week. Wallmann
