NWS Forecaster Discussion

Area forecast discussion 
National Weather Service Boise Idaho 
308 am MST Thursday Feb 11 2016 

Short through Friday...a strong upper level ridge 
today will shift east on Friday. The strong ridge will allow the 
inversion to continue today...with low clouds and patchy fog this 
morning. So far...dense fog has been isolated and 
temporary...probably due to the middle and high level clouds 
streaming through the area. The limited moisture will bring only 
isolated showers across the far north /areas from Baker City to 
McCall/ this afternoon and evening. Inversion will start to 
weaken on Friday as southwest flow aloft moves into the area ahead 
of an approaching upper level trough. However...kept patchy valley 
fog in the forecast due to low mixing heights and light 
winds...except from Mountain Home to Jerome where east winds of 
5-15 miles per hour should prevent fog from developing. Temperatures will 
trend slightly warmer in the valleys and cooler in the mountains 
due to the weakening inversion. 

Long term...Friday night through Thursday...a more active 
weather pattern expected through the extended period as a series 
of through moist troughs moves through the Pacific northwest. The 
first shortwave will move through the region early Saturday and 
bring a chance of precipitation to the southeast Oregon and SW Idaho 
mountains. Snow levels remain high Saturday between 5000-7000 feet 
mean sea level. Moist northwesterly flow with another shortwave follows on 
Sunday for a better chance of precipitation across the forecast 
area. Snow levels again will remain above 5000 feet. Upper level 
ridge will begin to rebuild northward on Monday pushing the plume 
of moisture north of the forecast area. The ridge will be short- 
lived as another stronger trough reaches the Pacific northwest 
coast Wednesday. Temperatures ahead of the trough on Monday 
through Wednesday will be quite warm approaching the upper 50s to 
low 60s in the Snake River Plain. The upper level trough/cold 
front moves across the region on Thursday for another round of 
precipitation. Snow levels will fall with the trough passage from 
5000 feet to 3500 feet Thursday evening. 


Aviation...MVFR conditions in low stratus and fog in the lower 
valleys this morning. Broken to overcast high cirrus this morning 
will likely limit fog development...though to expect kbno and kmyl 
to see fog this morning. Less confidence fog/stratus at kboi this 
morning. Expect any fog/stratus that does develop to dissipate 
this afternoon except in the lower Treasure valley. Surface 
winds...variable mainly less than 10 kts. Winds aloft through 10k 
feet mean sea level...southwest to west 10-20 kts. 


Air stagnation...the inversion will persist through Friday...with 
the top of the inversion layer at around 1500-2000 feet above ground level. The 
passage of a cold front on Saturday should be strong enough to 
remove the inversion and provide better mixing.
