NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Boise Idaho 
343 am MST Sat Jan 31 2015 


Short term...today through Sunday...inversion and high pressure 
surface/aloft will weaken Sunday. Inversion in a somewhat dry 
airmass /pw in the 10-20th percentile/ will bring mostly clear 
skies to the mountains and allow for limited stratus and patchy 
dense fog this morning. Stratus at 3 am was across much of S 
central Idaho...SW Owyhee County and in patches across central 
Harney and north Baker counties. The weakening ridge will allow 
for snow likely across the west central mountains /rain below 4k 
feet mean sea level/ and a chance of rain and snow along and northwest of a line from 
Banner Summit to Bogus Basin through Cambridge to Burns /as well 
as Steens mtn/. With half-inch precipitable waters  forecast by the GFS Sunday 
afternoon quantitative precipitation forecast/snow amounts may increase as the event gets closer 
but for now kept quantitative precipitation forecast light around 0.06 inches /or an inch of snow/ 
mainly across the west central mountains. 




Long term...Sunday night through Saturday...moist westerly flow 
will be the dominant weather feature through the first half of the 
week - bringing several rounds of light precipitation to southeast 
Oregon and southwest Idaho. The wettest period will likely be 
Monday afternoon through Tuesday afternoon as flow is enhanced by 
an embedded upper level short wave. Temperatures and snow levels 
will be high enough for both rain and snow across mountain 
valleys...including the Long Valley and Camas Prairie. Drier 
Wednesday and Thursday as a Pacific Ridge builds inland...cutting 
off the moisture supply to Oregon/Idaho. Ridge will shift eastward 
on Friday...allowing southwesterly flow on the back side of the 
ridge to transport low-level moisture northeast into the area. 
Expect wet conditions /especially across higher terrain/ Friday 
night through early Sunday. 


&& 


Aviation...at 10z...LIFR-IFR fog was present at kbno and 
expected to develop across other locations /including kbke kboi 
keul kmyl/ around 12z. Fog and IFR stratus at kjer likely to 
persist until 19z today. Othwerwise...VFR conditions and light 
west/northwest surface winds will prevail. Northwesterly winds aloft will 
average 20 kts through 10k feet mean sea level. Patchy LIFR fog likely to 
return Sunday morning.
