The episode as NWS OTX wrote it up.
A strong and windy cold front swept across eastern Washington during the afternoon of April 27th. Across the Columbia Basin sustained winds of 20 to 30 mph with recorded |gusts as high as 46 mph promoted areas of blowing dust in the western basin. In |the Spokane area two trees were toppled onto homes. These were isolated events probably caused by local terrain and random mixing of stronger winds aloft down to the surface.

Area Forecast Discussion
National Weather Service Spokane WA
1200 PM PDT Sat Apr 27 2019
.SYNOPSIS...
Today will be cool and windy, with scattered rain and snow
showers. Breezy, cool and showery weather will linger in some
degree into next week. The chilly weather pattern will heighten
the risk for low temperatures to dip below freezing the next
several nights especially in lowland sheltered from the wind.
&&
.DISCUSSION...
Windy conditions will be the main story this afternoon. A surface
low has quickly deepened over southern Alberta and western Montana
this afternoon and a cold front has surged east of the Continental
Divide. Stiff cold advection and a tight pressure gradient across
the Inland Northwest will produce sustained winds of 15 to 25 mph
and gusts in the 30 to 35 mph range across the Upper Columbia
Basin into the Spokane area. Localized gusts of 40 to 50 mph will
occur around Wenatchee, Chelan, Vantage, and Waterville as cool
air squeezes through the gaps in the Cascades. Blowing dust is a
concern around Moses Lake, Ephrata, Othello, and Warden where
spring crops are being planted. We are keeping a close eye on
social media and web cameras for reduced visibilities as winds
peak during the early to mid afternoon hours.
Afternoon temperatures have been raised a few degrees this
afternoon in the Columbia Basin, Palouse, and Spokane area to
better fit the late morning trends. By noon, readings probably
won't climb much as convective temperatures will be reached. Mid
and upper level cold advection behind our powerful cold front will
also hinder warming this afternoon.
&&
.AVIATION...
18Z TAFS: A strong cold frontal system moves through today
tightening both the pressure and thermal gradients across the
region, and bringing strong gusty winds to all TAF sites.
Isolated rain and snow showers will form over the northern
mountains and move southward into the KGEG/KSFF/KCOE/KPUW and KLWS
sites. Blowing dust is also possible this afternoon from the
Columbia Basin across the western Prairie into Spokane and the
Palouse, but low confidence precludes inclusion into the TAFs at
this time. Winds will gradually decrease after 02-04Z. /aky
