AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
246 AM PDT Wed Jul 10 2013

.SYNOPSIS...

High pressure will bring dry and warm weather through today. An
approaching system will promote breezy winds this afternoon.
Thursday to Saturday will be occasionally breezy with near or
slightly below normal temperatures. there will be a slight chance
of showers and thunderstorms for Friday and Saturday, especially
around the northern mountains. A warming trend is expected early
next week, with a slight chance of thunderstorms over the eastern
mountains by Tuesday afternoon.

&&

.DISCUSSION...
Wednesday through Thursday evening: A deep upper-level trof
will swing into Western Canada Wednesday then sag into the Pac NW
Thursday. This will usher a cold front through the region on
Wednesday followed by strong cold advection through much of day
Thursday. For the most part, this will be a dry cold front passage
with a well pronounced dry slot punching across the region
Thursday leading to mostly clear skies and dry conditions for most
locations. The one exception will be a layer of elevated
instability and moisture getting drawn northward into southeastern
WA and the lower ID Panhandle Wednesday night into Thursday
morning before the main trof sags into the region. Models have
come into better agreement regarding the placement of this
instability axis (100-200 J/kg of MUCAPE within the 700-500mb
layer) which is expected to stretch from the Blue Mtns...through
the Palouse... and into the Central Panhandle Mtns of Idaho. There
are a few fragments of energy shearing from the upper-level low
off the CA Coast, otherwise lift along the approaching upper-level
front will be the triggers for nocturnal convection and given
increasing confidence, we have introduced dry thunderstorms
through the overnight periods. NAM does spit out QPF amts from
0.01 to 0.06" but strengthening 700-500mb flow (on the order of
40-45 kts) within this axis of instability should promote rapid
storm motion and very small chances for measurable rain unless
storms begin training.

The main issues with the dry cold front passage will be related
to fire weather and potential for rapid fire spread. The cold
front on Wednesday will be late in the day allowing temperatures
to warm near or slightly warmer then Tuesday or into the 90's for
most lowlands. Pressure gradients will begin strengthening by
midday and continue well into the evening as a 1000mb low deepens
over southern Alberta. This will set the stage for 10-12mb KGPI-
KPDX cross CWA pressure gradient yielding increasing winds on the
order of 10-20 mph and gusts to 30 mph. Gusts across the
Basin, West Plains, and Palouse will be lower...generally near
25 mph and sustained winds of 14-19 mph will be more of an issue.
With the warm temperatures, afternoon humidities between 12-20%,
and sustained winds near 15mph or greater...we have gone ahead and
upgraded the fire weather watch to a red flag warning. Critical
wind and RH combinations will focus within the 2PM to 8PM
time-frame with the strongest winds within the Wenatchee Valley and
Waterville Plateau likely to be the strongest of the region
(sustained 20-25 mph) and peak between 5-8PM.

Winds will settle down overnight Wednesday however as the trof
sags into the region on Thursday...strong cold advection will
continue to bring breezy winds across the region. The strongest
winds will once again focus from the East Slopes to the ID border
including the Columbia Basin... Waterville Plateau...and Palouse.
Despite the cooler temperatures on Thursday, dry air will remain
in place and the combination of breezy winds and low RH's will
keep an elevated risk for wildfire spread so the Red Flag Warning
will continue through Thursday evening. So the fire weather
highlights will state from Wednesday afternoon through Thursday
evening but the most critical times will be 2PM through 8PM on
each of these afternoons. /sb

Friday through Sunday...While no models suggest any significant
weather systems expected through the area for the rest of the
short term...a series of weak ripples in the upper level flow will
brush through the region...the main effect of which will be to
shove the surface thermal trough eastward into Montana leading to
slightly cooler high temperatures...slightly below normal for
Friday and Saturday and then creeping back to normal by Sunday.
Also locally breezy westerly winds will persist each afternoon
an evening over much of the basin and especially near the Cascade
gaps. The potential for any precipitation is small...with the best
chance being a mere slight threat of some showers and
thunderstorms with an approaching wave on Friday night and
Saturday morning. This wave is expected to weaken as it transits
the region...and moisture is sparse with only marginal elevated
instability. Thus...there is little to be concerned about as far
as any appreciable thunder threat at this time.

Sunday night through Tuesday...the latest available models all
suggest a return to a ridgy summer pattern in the extended period
featuring temperatures rebounding to above normal through the
middle of next week...with seasonably dry conditions and
primarily terrain driven light winds. There is a potential for some
monsoonal moisture to work it's way into the region on or about
Tuesday...which will provide likely the only possibility of any
thunderstorms way out in the far reaches of the extended
period...too early to put much faith in this possibility and thus
warranting only 20 percent pops at this time. /Fugazzi

.AVIATION...
06Z TAFS: VFR conditions at all TAF sites through 06z Thur.
Southwesterly winds will begin to increase btwn 18-21z Wed.
Sustained winds 15-20 mph is possible with gusts up to 25 mph. The
windier TAF locations will be KMWH and KEAT. Winds will remain
elevated through the evening hours.
