Area Forecast Discussion
National Weather Service Spokane WA
621 PM PDT Thu Oct 19 2017

.SYNOPSIS...
The forecast will remain wet and breezy at times tonight through
Friday as a low pressure system slowly sags through the region.
There will be a brief break in the precipitation Friday evening,
but that will be short lived as another warm...wet...and windy
weather system arrives on Saturday and exits Sunday. Drier
conditions are expected for much of next week.

.DISCUSSION...
A cold front is taking its time to push across the Inland
Northwest. The upper level trough of lower pressure off the coast
has dug through the afternoon. This in effect oriented the jet
more meridional, which then limited the amount of westerly flow
to push the front across. Much of the rain along the front today
has remained over the basin and up into the Okanogan Highlands
and Northeast Mtns. The forecast was adjusted to move the front
through slightly slower. Rain is expected to start at Spokane
within the hour by 7:00 PM or so and into Coeur d`Alene closer to
8:00 PM. Pullman and Lewiston is expected to see rain start
between 9:00 and 11:00 PM. Some moderate rainfall amounts will be
possible with around a half an inch of rainfall expected over much
of extreme eastern WA and into the ID Panhandle by Friday
morning. /SVH

.AVIATION...

00Z TAFS: A slow moving cold front will track across the region
this evening bringing light rain to all TAF locations. Cigs and
visibilities should remain VFR. Behind the front, gusty westerly
winds will develop and continue through the day on Friday.  RJ
