Area Forecast Discussion
National Weather Service Spokane WA
1039 AM PDT Sat Jul 30 2016

.SYNOPSIS...
The passage of a dry cold front today will produce dry and breezy
conditions. Winds will peak this afternoon and early this evening
raising concerns for rapidly spreading wildfires. Sunday will be
cooler with afternoon highs in the 80s. Another potent cold front
is expected on Tuesday, and will likely produce more windy weather
as well as the chance for thunderstorms along the Canadian border.
A dry and warmer weather pattern with less wind is expected
late next week.

.DISCUSSION...
Made a few adjustments for the winds today. Surface pressure
gradients are tightening across the Cascades with about 8 mb from
Seattle to Wenatchee. Winds picked up to about 16mph out of the
NW in Wenatchee and expect this to steadily increase through the
afternoon. Guidance suggests even stronger NW winds with the
potential of gusts of 40 mph by early evening from Wenatchee,
across the Waterville Plateau and into the Moses Lake area. Breezy
and gusty conditions will develop with SW winds of 15-20 mph from
the West Plains to the Palouse. These winds have the potential to
kick up dust, have added patchy blowing dust to the forecast. Main
concern will be for fire weather as the humidities lower into the
teens this afternoon and evening. No changes to the current Red
Flag warning today. /rfox.

.AVIATION...
18Z TAFS: VFR conditions expected at all TAF sites through 18Z
Sunday. Not much in the way of clouds to discuss as clear skies
continue. The passage of a dry cold front will usher in cooler and
breezy winds for the afternoon through about 4z. All TAF sites
will experience gusty winds. Expect sustained winds of 12-18 kts
with gusts up to 25 kts at most TAF sites. A tighter pressure
gradient across the Cascade Mtns will result in stronger and
prolonged winds at KEAT with gusts to between 35-40 kts possible,
especially for for the early evening hours. Winds will gradually
subside overnight. /rfox.
