 Special Statement  Statement as of 2:43 PM MDT on October 20, 2014


... Major change in the weather Tuesday...

A strong upper level disturbance will move through eastern Oregon
and southwest Idaho tonight and early Tuesday. This will bring
showers and gusty winds to the area. Isolated thunderstorms are
forecast just ahead of the center of the upper low... a path that
extends from central and southern Harney and Malheur counties...
northeast through the Treasure valley... and into the Boise
Mountains and Camas Prairie. Precipitation amounts will range from
a tenth of an inch to a quarter inch in the valleys... and from
half an inch to an inch in the mountains. A couple inches of snow
will fall above 7000 feet... with up to 4 inches above 9000 feet.
High temperatures tomorrow will be around 20 degrees below today/S
readings... ranging from the upper 50s to lower 60s in the
valleys... and 30s and 40s in the mountains.

We are in for another quick change Wednesday... as milder weather
rapidly returns... along with mostly sunny skies. Temperatures will
rebound 5 to 10 degrees to put most areas right back near normal.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Boise Idaho 
905 PM MDT Monday Oct 20 2014 


Discussion...a well defined upper low pushing into northern California 
this evening was seen best in water vapor satellite pics. The 
18z and early 00z models have the position of the low well 
initialized and are showing little change in its forecast track 
and timing from previous solutions. Showers are already developing 
across central Idaho in the strong southerly flow ahead of the low 
center. Expect this to continue overnight and given the elevated 
instability and could even see a thunderstorm or two over the 
mountains precipitation increases in coverage Tuesday morning as the 
upper low tracks from southeast Oregon into the west-central Idaho mountains 
the dynamics of this system will support heavier showers and a 
slight chance of thunderstorms Tuesday morning in vicinity of the 
low which would include the Treasure valley and west-central and 
Boise Mountains the western Magic Valley still looks to be on fringe 
of the best dynamics so precipitation amounts will be lighter. 
Will make some updates to the forecast to better fit the current 
conditions. 


&& 


Aviation...VFR this evening. Showers becoming widespread after 06z 
with areas of terrain obscuration and local MVFR ceilings in the 
mountain valleys. Conditions improving from the west after 18z... 
except showers continuing in the central Idaho mountains through the 
afternoon. A cold front will cross eastern Oregon tonight and 
southwest Idaho Tuesday morning. Surface winds...southeast to S 5-15 kts 
becoming west 10-20 kts behind the front. Winds aloft at 10k feet 
mean sea level...SW up to 25 kts becoming west up to 15 kts behind the front. 


&& 


Previous discussion... 
short term...tonight through Wednesday...large upper level low is 
just coming onshore this afternoon. It will swing east-northeast overnight and 
pass over the County Warning Area late tonight and tomorrow morning. This will help 
spread showers over the area. There is a slight chance of 
thunderstorms immediately ahead of and under the center of the 
low...and this was added to the forecast for the period of 06z to 18z 
Tuesday. Quantitative precipitation forecast amounts will be more like a cold season system...with 
around a quarter inch forecast for the valleys and up to an inch in 
the highest elevations of the west-central mountains. The front will 
move through eastern Oregon overnight and through SW Idaho between dawn 
and noon. Winds with the front could briefly gust to 30 
kts...depending on the amount of convection that develops. Winds near 
any thunderstorms that develop could briefly gust to 40 kts. With 
cloudy and showery weather Tuesday combined with Post-frontal 
air...temperatures will be down around 20 degrees from today. Lows Tuesday 
night will be down near normal in most locations...with highs Wednesday 
rising right back up to a few degrees above normal. 


Late Wednesday the next system will approach from the west. Clouds will 
stream in to eastern Oregon from the SW as a slight chance of showers 
develops along extreme northwest Harney County and the higher terrain of 
Baker County. There is also a slight chance that showers could 
develop in the higher terrain of northern Adams and valley counties. 


Long term...Wednesday night through Monday...there is good model 
agreement that the area will transition into a southwest flow as 
an upper low sits off of the British Columbia coast. As the low 
starts to move south on Thursday...models are showing some 
moisture streaming into the area. As of now...precipitation chances 
through the end of the week look to remain in the west central 
mountains in Idaho and in northern portions of Baker and Harney 
counties in Oregon. The low is expected to finally move inland 
some time over the weekend...although there is still much 
uncertainty over the details. For now...near climatology probability of precipitation remain 
through Monday. Temperatures look to remain at or slightly above 
climatological normals.
