Area Forecast Discussion
National Weather Service Spokane WA
245 PM PST Thu Mar 9 2017

.SYNOPSIS...
A potent storm will spread rain and snow throughout the region
tonight. Strong winds will accompany the system Friday. The
combination of rain and snow melt will bring a threat for
localized flooding. A brief break is expected by Friday night into
early Saturday, although more unsettled weather is forecast into
early next week with rain and mountain snow. Temperatures are
expected to warm on Friday into next week.

&&

.DISCUSSION...

...WET AND MILD STORM SYSTEM TO BRING INCREASED RUNOFF INTO FRIDAY AND
POTENTIAL FOR FLOODING ISSUES...

Tonight through Friday: Afternoon satellite reveals a deep surface low
approaching Vancouver Island steering a rich plume of subtropical
moisture into the Northwest on its southern flank. The moisture
is ascending isentropically ahead of a strong warm front currently
stretching west to east along the WA/OR border. The shield of
precipitation has recently expanded across most locations with the
primary precipitation type falling as rain in the lowlands. There
are some exceptions being in the East Slopes and far northern
valleys. However CAMS and surface obs indicate snow is mainly
melting on contact. As the sun sets, we should start to see snow
accumulate with the greatest risk for accumulations in the upper
reaches of the Methow Valley, Cascade Passes, Sherman Pass, and
far north Idaho Panhandle mainly around Bonners Ferry, Eastport,
and Porthill. Temperatures overnight should not drop from the
current readings and actually warm across much of the Columbia
Basin. Mid to upper 40s exist in the foothills of the Blue Mtns as
of 2PM. As winds increase from the south then southwest, expect
this warming to punch northward across much of the Basin and into
the lower Idaho Panhandle with many locations reaching the 40s
early Friday morning.

Winds of 10 to 25 mph are expected to develop overnight...becoming stronger
with a cold front passage early Friday morning and remaining
gusty through midday. We have seen a slight decrease in modeled
winds and now speeds are just teetering just under local
thresholds for wind highlights. I will allow the evening shift to
take another look at the 00z models and make the call. Needless to
say, sustained winds in the lower Columbia Basin will increase
near 25 mph give or take 5 mph early Friday morning coupled with
gusts 30-40 mph. A few locations near the Blue Mtns like Pomeroy,
La Crosse, and Alder Ridge may have locally stronger gusts for a
few hours.

The most appreciable precipitation with this event will focus over the Idaho
Panhandle and far eastern reaches of WA as well as the Cascade
Crest. QPF amounts will exceed an inch in the Central Idaho
Panhandle and Cascade Crest with amounts decreasing closer to half
an inch into far eastern WA. Amounts closer to a quarter of an
inch are expected in the lee of the Cascades. Snow levels will
begin between 3000-4000 feet but look to come up close to 6000
feet for locations from Lookout Pass to Wilbur to Stevens Pass
overnight. Mild temperatures and gusty winds will quickly eat away
at the resident snowpack and the combination of runoff from snow
melt and overnight rains raises concern for flooding. As such,
flood watches have been issued. Main concerns will be field
flooding, creeks and streams, seepage into basements, plugged
culverts leading to water diversion, and potential for rock slides
along sections of roads near steep terrain. A second point flood
watch was also issued for Paradise Creek in Moscow, ID which has a
moderate chance to rise above flood stage. /sb

Friday night through Sunday: A weak ridge will be building in the
region to start this period. It will lead to a drying trend for
the region. A few lingering showers over the Panhandle and
Cascades is expected early Saturday morning. The models are in
good agreement with the next wave of moisture expected on Saturday
afternoon. A low in the Gulf of Alaska will push a frontal
boundary through the region Saturday night. High snow levels will
make this a mainly mountain snow and valley rain event. Areas of
4000ft and above could see several inches of snow with lower
amounts to around 3000ft overnight. A few hundreths of rain is
expected for the low lying areas. Precip across the region will
continue to taper off throughout Sunday as another ridge fills in
behind the Low. Winds will be southwesterly around 10 MPH with
occasional gusts around 18 MPH. Temperatures will be in the 40s
and low 50s for highs and upper 20s and 30s for lows. /JDC

Monday through Thursday: The active pattern continues with a
chance of rain and mountain snow showers on Monday as a weak dirty
ridge moves over the region. Westerly flow aloft will likely
shadow much of the basin from precip, keeping showers mainly in
the Cascades and panhandle mountains. Beyond Monday models
disagree on timing of a few weak disturbances that will keep
slight shower chances around especially for the mountains. Models
come into a bit better agreement on the passage of a cold front
early Thursday bringing back more widespread showers with lower
snow levels. Post frontal southwest winds will be gusty in the
basin during the day Thursday as the surface trough passes from
southwest to northeast. Temperatures during the period will
continue to be at or even above normal, in the low 50s. This will
continue to melt low and mid level snow pack which means more
runoff and potential river and stream rises. /bwilliams

&&

.AVIATION...
00Z TAFS: A warm front is lifting into the region bringing wdsprd
rain and MVFR cigs to most terminals. As the rain ends aft
08z...expect a brief period of lowering cigs or fog. We do not
anticipate these restrictions to last long as winds increase
becoming quite gusty for locations like Pullman and Spokane. Best
chance for a few hours of fog will be at Wenatchee and Moses
Lake. The eastern TAF sites will have a better shot of upsloping
stratus but wind speeds suggest VFR visibilities and chance to
break into sct decks Friday aftn. /sb
