322 AM PST WED FEB 11 2015

...The flood warning continues for the following rivers and lakes in 
Idaho...

  Coeur d Alene River at Cataldo AFFECTING Kootenai and Shoshone 
  Counties

The Coeur d Alene River continues to run high after several days of 
wet and mild weather. The river level is dropping and is expected to
fall below flood stage this morning or early afternoon.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Additional information is available at:
http://water.weather.gov/ahps2/index.php?wfo=otx

The spring snow melt runoff in lakes and rivers is dangerously cold 
and can be life threatening for those that come into contact with the
water. Take appropriate precautions.

Be aware of large debris in the river. High water levels can push 
logs and other large debris into the river...increasing the danger to
people and boats.

Never drive cars...Trucks or sport utility vehicles through flooded 
areas. The water may be too deep to allow for safe passage. As little
as one foot of water on the road can move most vehicles off the road.

* At  45.0 feet...The County may begin pumping operations behind 
  levels above this stage if the river is expected to remain over 
  flood stage for a long duration.	
* At  44.0 feet...Homes near the river may experience some flooding of
  basements. Water will begin to cover CCC Road near the Mennonite 
  Church. Some water will be over the section of Latour Creek Road 
  immediately south of Interstate 90, near the campground. Due to the
  high water table some homes behind the Cataldo levee will be 
  surrounded by water. 
* At  43.0 feet...Minor flooding of farmland from Cataldo downstream 
  to Harrison is likely. The campground at Cataldo will also begin to
  flood. Portions of Dudley Road, west of Latour Creek, will likely 
  be underwater and impassable. If there is significant water already
  in the floodplain, these impacts may occur at lower stages. Old 
  Coeur d'Alene River Road on the North Fork of the Coeur d'Alene 
  River may begin to flood north of the Bumblebee Bridge.
* At  42.5 feet...Portions of Riverview Road between Cataldo and 
  Kingston will be flooded.
* At  42.0 feet...Portions of the campground south of I-90 and Dudley 
  Road, downstream of Cataldo, may be underwater if floodplain 
  storage areas are already full of water.

Area Forecast Discussion
National Weather Service Spokane WA
251 PM PST TUE FEB 10 2015

.SYNOPSIS...
Dry and mild weather is expected over the majority of the Inland
Northwest for the next several days. A weak weather system
Wednesday night and Thursday will bring the potential for
additional light rain in the Cascades and near the Canadian
border. A few record highs may be possible Friday and Saturday.
Temperatures should gradually decrease closer to average by early
next week.

&&

.DISCUSSION...

Tonight: There is not much left of the trough that produced days
of rain and record warm temperatures. As of 230 PM, the remnants
of the wet weekend trough was shearing apart over Montana and
Wyoming. Radar continued to detect some weak rain showers over
the southern Idaho Panhandle, but those have been on the decrease
this afternoon. That weakening trend will continue this evening a
upper level high pressure amplifies over the Pacific Northwest.

The left over low level air mass is mild and moist. Surface
dewpoints are in the lower to mid 40s from the Lower Columbia
Basin into north Idaho. The residual moisture will allow for areas
of low clouds and fog to develop and expand tonight. There should
be enough low level easterly wind over the southern Idaho
Panhandle and Palouse to bring clearing to places like Pullman,
Colfax and Pomeroy. Along and north of the I-90 Corridor will be
vulnerable to low clouds and fog which may linger into Wednesday.

Wednesday: The presence of clouds and fog will make all the
difference in the forecast for tomorrow. As upper level high
pressure amplifies overhead we will transition to a low level
easterly wind. This time of year that favors clearing over the
Palouse and southern Idaho while fog and low clouds stack up
against the Cascades. The unusually warm resident air mass and
warm ground temperatures may negate some of our climatological
tendencies for fog and low clouds. It is possible that Spokane,
Sandpoint, Moses Lake, Wenatchee, and Omak experience some degree
of clearing tomorrow. Spots that get several hours of sunshine
will be mild with temperatures in the 50s...possibly low 60s south
of Pullman. /GKoch

Thursday through Tuesday...There is general model agreement of a
flat ridge over the Inland Northwest Thursday through Saturday
with a couple weak weather disturbances clipping the area. Then a
cooler but mostly dry weather pattern is expected for early next
week.  Now for the details...

Thursday: A weak system will move up from the southwest clipping
northern Washington and the north Idaho Panhandle. This may bring
spotty light rain to the East Slopes of the Cascades and northern
mountains with snow levels around 6000 feet. Main effect from this
wave will be a thick shield of mid level clouds which will keep
temperatures from reaching their full potential. A moist boundary
layer over the northern valleys will also result in areas of low
clouds around Omak, Colville, and Sandpoint.

Friday: The ridge amplifies for dry conditions with a very mild
air mass over the area as 850mb temps warm to 5C near the Canadian
border to 10C near the WA/OR border. The boundary layer remains
moist for the Cascade and northern valleys...which may high temps
in the mid or upper 40s. Elsewhere however indications is that fog
and stratus will be limited and this could allow for some near
record high temperatures despite limited wind and mixing potential
due to a higher mid-February sun angle to warm up the lower
atmosphere.

Saturday: Models have trended further south with the next wave
that is now progged to track into northern Washington/north Idaho.
Prior runs from yesterday tracked this wave north of the region.
For now POP's have been increased to 20-30% across the northern
valleys/mountains and Idaho Panhandle...but if models continue to
show this further south track further increases in POP's may be
needed. Precipitation amounts look light. The timing of this wave
coming through in the early-mid morning and dry air aloft coming
in behind this wave and 850mb winds out the northwest at 15-25 kts
may allow for a better mixing day across the area with very mild
temperatures in the valleys...while a cooling trend begins in the
mountains as 850mb temps fall to 1-4C. Several areas are currently
forecast to have near record temps.

Sunday/Monday: The ridge amplifies off the coast allowing a cooler
but generally dry northerly flow with the shower threat confined
mainly to the Idaho Panhandle.  There is a lot of model
variability regarding how much cooler air makes it in...but most
guidance keeps the arctic air east of our area with 850mb temps
only dropping into the -4 to 0C range. This would result in a
gradual cool down especially overnight lows where drier air will
allow for more efficient radiational cooling.

Tuesday: The latest GFS keeps a continuation of dry northerly flow
while the ECMWF breaks down the offshore ridge allowing a system
to spread light precipitation across the area. The UKMET, GEM, and
prior 00z ECMWF model run support more of a GFS solution so this
idea is preferred at this time. JW

.AVIATION...
18Z TAFS: Our surface winds have decreased region-wide this
morning. The decrease in low level mixing has allowed a ragged
deck of low clouds and fog to form in the southwest upslope
regions of eastern Washington and north Idaho. Spokane, Coeur
D'Alene, and Pullman look to be stuck in a cloud deck below 1500
feet today. The development of east winds tonight may be enough to
break Pullman out of the clouds overnight, but the wind fields may
be marginal. Our optimistic TAF for Pullman may need adjustments
later as we get a handle on how widespread the stratus bank
becomes this afternoon. /GKoch
