...FLOOD WATCH IN EFFECT FROM MIDNIGHT PST TONIGHT THROUGH
SATURDAY MORNING...

The National Weather Service in Spokane has issued a

* Flood Watch for portions of Idaho and Washington, including 
  the following counties, in Idaho, Benewah, Kootenai, Latah, 
  Lewis, Nez Perce, and Shoshone. In Washington, Asotin, 
  Garfield, Spokane, and Whitman. 

* From midnight PST tonight through Saturday morning

* Flooding problems may occur Thursday and Friday as a storm
  system brings significant rainfall and much warmer temperatures
  to the region. Snow will turn to rain late Wednesday night and
  will be accompanied by warm and breezy weather on Thursday and
  Friday. This will cause significant melting of the snow on the
  ground below 3000 feet and could lead to localized flooding, 
  small stream flooding and ice jam flooding.

  Reports of ice jam concerns on Rock Creek in the town of 
  Rockford and on several spots along Hangman/Latah Creek have 
  been already been received. The Grande Ronde River recently 
  experienced an ice jam flood event. As the creeks and rivers 
  rise and bring more ice downstream, there is the risk for 
  additional ice jam flood issues. In the town of Rockford, if 
  the channel becomes plugged with ice at the bridge, flooding 
  could potentially impact the town. 

  The forecast for the Palouse River at Potlatch shows the 
  potential for significant rises and may approach flood stage 
  which would impact areas along the Palouse river between 
  Potlatch, ID and Palouse, WA. Monitor the river forecast for 
  this location at  
  water.weather.gov/ahps2/hydrograph.php?wfo=otx&gage=ploi1
    
	
Possible impacts:
  Urban flooding: Rain and melting snow will likely cause street
  flooding in urban areas which can impact residences and 
  business near those locations. Storm drains, culverts and 
  ditches plugged with snow and ice will exacerbate the 
  situation. Low lying areas with poor drainage may also 
  experience flooding. 

  Ice Jam flooding: Many of the region's streams and rivers 
  are covered with thick ice. As streams and rivers rise, it is 
  likely that some of the ice will break up and float 
  downstream. This could lead to ice jams at bridges or other 
  constrictions along the stream or river. Currently the areas 
  of greatest concern with this are the Grande Ronde River, 
  Hangman/Latah Creek, Rock Creek, St Joe River, St Maries 
  River, and the North Fork Coeur d'Alene River.

  Main impacts from ice jams are: 
    If water cannot flow past the jam, river levels can rise 
    rapidly behind the jams and flood areas upstream. 

    If the ice jam suddenly breaks up, a wave of water and ice 
    could rapidly flow downstream causing damage along the banks 
    of the river.

    Large pieces of ice can come out of the channel and cause  
    damage to levees and structures in the floodplain and along 
    the channel. Ice can also come out of the channel and cover 
    roads, which would affect ability of residents and emergency 
    services to access rural areas.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flood Watch means there is a potential for flooding based on
current forecasts.

You should monitor later forecasts and be alert for possible
Flood Warnings. Those living in areas prone to flooding should be
prepared to take action should flooding develop. If you see an ice
jam forming or flooding occurring notify the National Weather
Service or Law Enforcement.

snow will likely cause street flooding in urban areas which can impact
residences and business near those locations. Storm drains,
culverts and ditches plugged with snow and ice will exacerbate
the situation. Low lying areas with poor drainage may also
experience flooding. An area of concern is in the Vicinity of 
Moscow Idaho where Paradise Creek and other small streams are
running at or above bankfull this evening. There have been reports
of small streams in Whitman county running very high as well. 

Ice Jam flooding: Many of the region's streams and rivers   are

...FLOOD WATCH REMAINS IN EFFECT THROUGH SATURDAY MORNING...

The Flood Watch continues for

* Portions of Idaho and Washington, including the following 
  counties, in Idaho, Benewah, Bonner, Kootenai, Latah, Lewis, 
  Nez Perce, and Shoshone. In Washington, Asotin, Garfield, 
  Spokane, and Whitman. 

* Through Saturday morning

* Today will be Warm and windy. Temperatures in the 40s in the
  Idaho Panhandle and eastern Washington will produce runoff via
  melting snow. 

* Ice Jams: Rising water levels will raise concerns for ice jams
  on creeks and streams. If water cannot flow past the jam, river
  levels can rise rapidly behind the jams and flood areas
  upstream. If the ice jam suddenly breaks up, a wave of water and
  ice could rapidly flow downstream causing damage along the banks
  of the river.

* Poor Drainage Areas: Storm drains and culverts clogged
  with snow will also have the potential to produce ponding of
  water. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flood Watch means there is a potential for flooding based on
current forecasts.

You should monitor later forecasts and be alert for possible
Flood Warnings. Those living in areas prone to flooding should be
prepared to take action should flooding develop. If you see an
ice jam forming or flooding occurring notify the National Weather
Service or Law Enforcement.

What forecasters said that day

The local office's own words before this flood watch went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Spokane, WA wrote its last area forecast discussion before this flood watch went out at Feb 8, 10:24 AM PST, 3 hours 51 minutes earlier.

Area forecast discussion, Feb 8, 10:24 AM PST, 3 hours 51 minutes before
Area Forecast Discussion
National Weather Service Spokane WA
1024 AM PST Wed Feb 8 2017

.SYNOPSIS...
The next significant round of precipitation will begin this
afternoon and continue through Thursday night. Moderate to heavy
snow accumulations will occur over the mountains of far north
Idaho as well as central and northeast Washington. Mixed wintry
weather is expected for portions of the Columbia Basin towards the
Cascades tonight and Thursday. The widespread precipitation will
give way to hit or miss showers on Friday and Friday night. This
will be followed by a cold front which will deliver breezy
conditions and cooler temperatures for Saturday. Dry weather is
then expected for the latter half of the weekend and into early
next week as a strong ridge of high pressure builds into the
Pacific Northwest.

&&

.DISCUSSION...
The warm front is moving northward about 3 hours quicker than
previously thought. The forecast has been update to reflect higher
chances for precipitation through the rest of this morning and
into the afternoon. Snow amounts have also been updated to
reflect an additional 1 to 3 inches more snow across much of the
region for today. With a faster timing, this may also mean a
faster change over to rain tonight across the Palouse, Upper
Columbia Basin and in the valleys of the southern to central ID
Panhandle. Thus, the total snow amounts, which will include the
snow overnight, may not be that much different than previously
thought. I still need to dig into when that transition is
expected to occur, so the snow amounts tonight still reflect the
previous forecast. The highlights have been moved up a few hours
except for the Northeast Mtns and the Northern Panhandle. I still
think these areas won't see more moderate snow accumulations
until this evening and overnight. The evening commute is expected
to be impacted with snow covered roads and snow continuing to fall
by that time. I also added some blowing snow down the Okanogan
Valley. Emergency management has reported some drifting snow due
to the northerly winds. Winds are expected to gradually weaken
this afternoon. /SVH

&&

.AVIATION...

18Z TAFS:

...FREEZING RAIN AND/OR SLEET EXPECTED AT KMWH AND KEAT TONIGHT
INTO THURSDAY MORNING...

A strong warm front will overrun a cold air mass already in place
across the Inland Northwest. All TAF sites will start out with
light snow this morning. Snow will intensify this afternoon with a
quick transition to rain at KLWS early this afternoon and at KPUW
late this afternoon or evening. Colder air will take longer to
scrub out at KGEG, KSFF and KCOE with a 2 to 4 hour period of
freezing rain possible overnight after 05Z. The cold air will
likely remain in place in the lee of the Cascades, which will
include the KEAT and KMWH. Freezing rain or sleet is expected
from the western basin into Cascade valleys from the late evening
into Thursday morning. Around a tenth of an inch of ice
accumulation will be possible at KEAT and KWMH by sunrise on
Thursday. /SVH
