AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
508 AM PDT Thu Aug 22 2013

.SYNOPSIS...
Warm and dry weather will continue through Thursday. Chances for
showers and thunderstorms will increase Thursday night into Friday
as a moist upper level disturbance tracks across eastern
Washington and the Idaho Panhandle. Warm weather with the threat
for thunderstorms will persist through the weekend into early next
week as a moist southwest flow pattern remains over the region.

&&

.DISCUSSION...
Today through Friday: Low pressure along the north CA coast is
drawn north over the next 36 hours, bringing increasing shower and
thunderstorm chances to the region. Much of today will remain dry
with occasional middle and high clouds. A few leading
showers/t-storms may reach the Blue Mountains/Camas Prairie by
late afternoon. However the best chances hold off until tonight
into Friday. By this evening the north CA low begins to push into
OR. It evolves into a negatively-tilted open wave that tracks up
the Cascades and Columbia Basin this evening and overnight. All
guidance shows modest lift, with sharp vorticity max and promising
a DIV-Q field. There are differences as to the precise timing and
track of the best lift, but all show showers/thunderstorms
expanding from the south.

The best chances remain south of I-90 before midnight, then the
threat encompasses much of the region overnight into Friday
morning. By Friday afternoon the wave shifts northeast. As such
the focus for the more numerous showers and thunderstorms shifts
toward the northeast mountains and northern Panhandle, though at
least isolated showers/t-storms will remain a threat about the
eastern Columbia Basin through lower Panhandle.

While models disagree over the extent of available instability,
from late tonight through Friday there will be opportunity for
scattered thunderstorm coverage with a potential for abundant
lightning. Measurable precipitation may initially be limited. As
such as fire weather watch remains in effect for much of central
and eastern WA and north ID for tonight through Friday afternoon.
We will continue to look over details for possible upgrade later
this morning, if not sooner.

In addition to the shower/thunderstorm chances, some breezy and
gusty conditions are expected on the backside of the passing
shortwave system. As for temperatures, today is expected to be
warm with values several degrees above normal. Highs are projected
to reach the upper 80s to lower 90s in many valley/basin
locations. However behind the wave, Friday's highs are forecast to
be some 6 to 12 degrees cooler than today. /J. Cote'

Friday night through Monday night...Latest GFS and EC models
continue to be consistent over previous runs and in decent
agreement with the overall synoptic flow regime featuring
sustained southwesterly flow aloft over the region ahead of a
stationary/slow moving trough close offshore the Pacific Coast.

Both models feature a series of sub-synoptic disturbances riding
this flow and transiting the region form southwest to northeast
during the extended period. Timing and strength of these waves is
different between the models.

The overall pattern climatologically favors an active thunderstorm
threat especially over the mountains north and east of the
basin...and this threat could also encompass the Cascades and even
the basin as any disturbances pass through adding dynamic lift to
the generally available orographic forcing each afternoon and
evening. Thus...confidence is pretty high for at least a small
threat of mountain thunderstorms pretty much each afternoon and
evening through the period. Confidence is also high that there
will be periodic disturbances bringing a more general chance of
thunder but timing is less certain. Relying mainly on the GFS
model (although the ECMWF also hints at this) a stronger wave will
pass Sunday afternoon and Sunday night bringing an enhanced chance
of thunderstorms to the Cascades...with another
disturbance...weaker...Monday night which will focus nocturnal
convection manly over the eastern third of the forecast area.

Through this time frame the surface thermal trough will be shifted
to the east and lay over Montana which should bring some relief
from the recent above normal temperatures with daytime highs
generally in the low to mid 80s over most populated areas. /Fugazzi
/Fugazzi

Tuesday through Thursday: The continued unsettled southwesterly flow
pattern will continue for the region as we are influenced by a
system sitting off the Washington-South BC coastline. Depending on
model of choice would determine if the system was a closed low
(GFS) or open wave (Euro)...but both solutions render similar
weather patterns for our forecast area. In the moist SW flow
daytime convection will be a strong possibility but will need the
topography to initiate so storm chances remain in the higher
elevations around the region. In the SW flow the areas most
susceptible would be the Cascade crests along with the NE Mtns of
WA and the ID Panhandle. Moving to the end of the period is where
things get inconsistent. The GFS wants to eject the system
earlier (overnight Wednesday) whereas the Euro would lag 6 to 12
hours exiting during the day Thursday. With a daytime exit we may
see increased coverage of showers and t-storms due to increased
instability...but this will have to be determined later when
models come into better agreement. Winds look to be gusty in the
afternoon with the tighter gradient and temperatures will remain
at or a couple of degrees above normal for most of the region.
/Fliehman

&&

.AVIATION...
12Z TAFS: The only possible MVFR condition will be from wildfire
smoke around KEAT, but the threat is not significant enough at this
time to include in the TAF forecast. Mid to high level clouds will
continue to stream through the next 12 hrs or so. Aft 00-02z Fri we
will see an increased chance of thunderstorms across SE WA and
central ID panhandle including KPUW and KLWS. Aft 05z the threat
of thunder will expand west toward KMWH and north into the KGEG
area. /J. Cote'
