NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Boise Idaho 
245 PM MDT sun Sep 21 2014 


Short term...Flash Flood Watch in effect through this evening in 
southern-most Idaho zones except the Owyhee Mountains. Upper low has 
become well-defined in Nevada as it moves northeast. At 2 PM MDT 
kcbx radar showed an area of showers in S-central Idaho moving 
toward the west-northwest. More showers along the Idaho/Nevada border were also 
moving westward and gradually expanding northward into Owyhee County. 
No heavy rain so far that would cause flash flooding but deeper 
moisture in Nevada has yet to reach our County Warning Area. Upper low is now 
forecast to move northeastward into southern Idaho this evening then turn eastward 
across southern Idaho tonight and into Wyoming Monday morning. Showers 
are expected to stay mainly along and east of that track. 
Meanwhile...a frontal band can be seen on satellite off the northwest 
coast along 132w at 20z. Models take it inland Monday and develop 
showers across our northern Oregon zones Monday night before dissipating 
in northern Idaho Tuesday morning. At the same time the main upper ridge 
to our south will build northward into our County Warning Area bringing clearing and 
warming Tuesday. 


Long term...Tuesday night through Sunday...models continue to show 
a progressive pattern with an amplifying upper level ridge exiting 
to our east as a deep upper level trough approaches from the west. 
Southwest Idaho and southeast Oregon will be between these systems 
through Thursday...and temperatures will continue above normal 
ahead of the slow moving cold front in advance of the trough. No 
precipitation is expected Tuesday night through Wednesday 
evening...then showers will spread across eastern Oregon into the 
west central Idaho mountains on Thursday. We can expect scattered 
showers and isolated thunderstorms across most of our area on 
Friday...decreasing to scattered mainly mountain showers over the 
weekend. Models have come into better agreement on timing the cold 
front as it crosses our area on Friday. Following the front the GFS 
brings the upper level trough inland a bit faster than the European model (ecmwf) 
which may reflect GFS speed bias in the longer range. Nevertheless 
both models show similar cooling with maximum temperatures around 5 
degrees below normal both Friday and Saturday. For Sunday confidence 
is much lower as model solutions diverge. 


&& 


Aviation...mostly VFR. Showers will stay mainly east of a kreo-kono- 
kmyl line through tonight. Widespread locally heavy showers and 
isolated thunderstorms south of the Snake River Valley will spread 
north over the Boise Mountains east of kboi and Idaho City after 
00z. Expect local MVFR conditions and terrain obscuration. Showers 
will decrease to scattered after 06z and continue over the west 
central Idaho and Boise Mountains through Monday. Surface winds... 
variable 10 kts or less. Winds aloft...easterly up to 15 kts at 10k 
feet mean sea level.
