Area Forecast Discussion
National Weather Service Spokane WA
1032 PM PDT WED SEP 17 2014

.SYNOPSIS...
A weak cold front will move through Washington and Idaho on
Thursday. The front will push temperatures closer to normal and
bring the potential for widely scattered showers on Thursday. A
high pressure ridge will return Friday and promote warm and dry
weather through the weekend.

.DISCUSSION...
Evening update: tracking a jet streaking coming up through
CA/southern OR and projected to advance toward northeast
OR/southeast WA/central ID late overnight into Thursday morning.
Both the HRRR and NAM Hi-Res have been indicating some shower
threat expanding up through south-central/eastern OR and southern
ID the Blues/Camas Prairie and Central Panhandle between 09Z and
15 or 18Z Thursday (late overnight into Thursday morning). Some
guidance suggest perhaps as far northwest as the Pullman area, but
confidence is not great enough to go that far north. I wouldn't be
surprised to see some sprinkles that far north though. Overall I
increased PoPs and sky cover over southeast WA through the central
Panhandle. I kept some mention of smoke in that region through
early overnight before the potential shower threat will less than
threat. But this will continue to be assessed. Otherwise the
forecast looks on track and overall the precipitation that comes
with this system still does not look overwhelming. /J. Cote'

.AVIATION...
06Z TAFS: A moist southwest flow and incoming cold front/upper
trough impact the Inland NW, providing increased cloud cover and
the threat of a few showers. The best shower chances will be near
the Cascades, including EAT, and over the northeast mountains
going into later tonight into Thursday. A threat will come up
through the Blue Mountain and toward the Central Panhandle of ID
late overnight into Thursday morning, potentially near LWS and PUW
between 09-15Z. Other chances will be found in the vcnty of GEG to
COE in the afternoon with the passing front. There is also the
slight risk for -tsra across the MTNS of far eastern WA and north
ID. Expect increased winds Thursday afternoon, with gusts in the
20 to 25kt range, locally higher near EAT. Winds will gradually
abate after Thursday evening (after 02-04Z). /J. Cote'
