NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Boise Idaho 
826 PM MST Sat Nov 22 2014 


Discussion...numerous snow showers from the west central 
mountains through the western Magic Valley are associated with 
lift and moisture with a fast moving upper level trough. May get a 
quick inch or two on grassy areas across the west Magic Valley 
since temperatures are near 32f...snow showers there will 
decrease to scattered for twin/Jerome by 11 PM MST. Moderate northwest 
flow aloft will be moist enough for upslope showers to continue 
across the NE Oregon mountains and higher terrain of Owyhee/Twin Falls 
counties through Sunday morning and central Idaho mountains beyond Sunday 
evening. Post cold frontal gusty winds across the Magic Valley 
around 25 miles per hour at times tonight and Sunday morning are associated 
with building high pressure 2-4 mb/3hrs across SW Idaho through 
early Sunday morning. This feature may be strong enough to bring 
northwest winds to 10 miles per hour to Ontario towards 11 PM but snow cover did not 
entirely go away...surface winds are forecast less than 10 miles per hour 
through Sunday...so boundary layer winds from the GFS are 
preferred overnight as they capture the 35mph over Twin Falls and 
calm to 10 miles per hour over the Weiser basin and lower Treasure valley. 
Previous. No updates. 


&& 


Aviation....expect scattered MVFR and local LIFR conditions in snow 
in the ktwf/kjer area until about 06z. The mountains of Baker County 
Oregon and central Idaho including kmyl will see scattered MVFR/IFR 
snow showers through Sunday morning...becoming widespread after 18z. 
Patchy valley fog is possible kboi-kono 06z-18z. Otherwise expect 
VFR conditions through Sunday. Surface winds...west to northwest 5- 
15 kts except 15-20 kts in the kbke and ktwf/kjer areas until 
about 06z. Winds aloft...northwest up to 30 kts at 10k feet mean sea level. 


&& 


Previous discussion... 
short term...tonight through Monday...a cold front has moved 
through the area today...helping to scour away most of the 
inversion that has plagued the Treasure valley...and many other 
smaller valleys...the past week or so. We feel weak inversion 
conditions will continue tonight through Monday in the extreme 
lower Treasure valley and have adjusted our forecast accordingly. 
A moderate short wave will move through the area late this 
afternoon through tonight... bringing additional showers to most 
of the area. Snow levels this evening range from 4500 feet in the 
south to 3500 feet in the north. Overnight the snow level will 
drop to a range of 3400 feet in the south to 2700 feet in the 
north. Winds will remain moderate in the western Magic Valley this 
evening. Fog is likely in sheltered mountain valleys tonight...along 
with the usual areas near McCall... Baker City...and in the 
extreme lower Treasure valley. With moderate northwest flow aloft and 
weak ridging tomorrow...showers will be mainly confined to the 
mountains of SW Idaho and northern Baker County. Temperatures will be near normal. 
Showers will continue in the mountains Sunday night before tapering off 
Monday. The valleys will be dry Sunday night and Monday. Temperatures on 
Monday will be a few degrees cooler than Sunday...resulting in 
readings a few degrees below normal. 




Long term...Monday night through Saturday...upper ridge builds 
along the West Coast through Wednesday which will keep moist 
northwesterly flow and precipitation focused over the central 
mountains of Idaho. Clouds and little to no snow cover throughout 
much of the western Snake River Plain should provide at or 
slightly above normal temperatures. The ridge moves inland late 
Wednesday and by Friday the ridge axis is over the forecast area. 
This is when the inversion will be the strongest but the valley 
temperatures as well as fog/stratus development will depend 
largely on snow cover. At the moment...the lower Treasure valley 
stands the best chance for colder temperatures and inversion fog/stratus 
but overall confidence in the inversion forecast remains low. 
After Friday the ridge appears to weaken allowing Pacific moisture 
to move back into the Pacific northwest.
