Area Forecast Discussion
National Weather Service Spokane WA
1032 PM PDT Sun Sep 15 2019

.SYNOPSIS...
Cool, wet fall weather will persist through mid week as a pair of
weather systems slowly make their way across the Inland 
Northwest. Drier, breezy and more seasonal weather is possible 
late next week into the weekend.

.DISCUSSION...
Adjusted tonight's and Monday's forecast based on current radar
trends and some of the new 00Z models coming in. The frontal band
currently over central WA will move *very* slowly to the east,
reaching the WA/ID border by late Monday afternoon. You might be
able to walk faster than that. Just how well it holds together as
it makes this trip is a bigger question. But most of the higher
resolution models show that while the band may weaken later
tonight, it should reorganize itself a bit when it reaches extreme
eastern WA on Monday. We won't see very much rain from this front.
But the persistent light rain and heavy clouds should do quite a
number on the temperatures on Monday. I knocked a few degrees off
of most locations east of Ritzville for Monday, figuring that some
folks may not make it above 60F. The Cascades had their cold wet
day today. The other half of the Inland NW gets its turn on
Monday.  RJ

.AVIATION...
06Z TAFS: Cold front is moving very slowly to the east. Rain band
currently between KEAT and KMWH won't reach Spokane until midday
Monday. KMWH may have some MVFR cigs in the morning, but
confidence is too low to put in the TAF forecast at this point.
The potential for lower cigs at KGEG/KSFF/KCOE doesn't look quite
as good. The rain for these locations should wait until after 18Z
when it would be harder to form lower ceilings. That said, the
front is expected to strengthen a bit over extreme eastern WA so
this could lead to lower cigs before any rain occurs. All sites
should clear out by late afternoon or evening as the front finally
pushes through.  RJ
