Synopsis...
scattered showers will bring brief periods of rain and possibly
graupel to north Idaho and northeast Washington this afternoon and
evening. The majority of Saturday should be dry before a frontal
system brings the potential for rain Saturday night and gusty
winds for Sunday. The middle of next week will be warm with
afternoon temperatures in the 60s to near 70 degrees.

Discussion...
the forecast for today has been updated to refine the chance for
showers over the Idaho Panhandle and northeast Washington this
afternoon and this evening. Remnants of an elongated 500mb trough
will allow diurnally driven showers from Colville to Sandpoint to
Coeur D'Alene to the Silver Valley. A lightning strike or two will
be possible, but there isn't a great deal of upper level support
for enhancing updrafts.

Late afternoon and evening winds have been increased around
Wenatchee into the 15 to 25 mph range. The west to east pressure
gradient wind will be enhanced by cool advection through the
Cascade gaps. /Gkoch

Aviation...
18z tafs: afternoon destabilization will produce scattered showers
over northeast Washington and the Idaho Panhandle this afternoon
into this evening. For the Spokane and Coeur D'Alene airports, the
best shot for scattered showers will be in the 21-03z time frame.
Locally breezy winds are expected at Wenatchee in the 22z-04z time
frame as Cascade Gap winds are enhanced in the late afternoon and
early evening. /Gkoch
