NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Boise Idaho 
307 am MST Thursday Dec 18 2014 


Short term...today through Friday...the northern portion of a 
split trough will continue to move through the area today. Light 
showers will accompany the trough...with the bulk of the activity 
residing to the west and north of Boise. The showers will decrease 
in coverage this afternoon and evening as the system moves east. 
Snow levels between 3000 and 3500 feet will rise to near 4000 feet 
this afternoon. Light snow accumulations of an inch or less are 
possible in the west central mountains. An upper ridge axis will 
bring a brief dry period to much of the area this evening while a 
more vigorous trough moves into the Pacific northwest. This trough 
has ample moisture with it to deliver precipitation to all of southeast 
Oregon and SW Idaho on Friday. However...model quantitative precipitation forecast and snow 
amounts are not impressive. Looking for an inch or two of snow 
above 3500 feet and 2-4 inches in the mountains. Snow levels will 
remain generally above 3500 feet although elevations between 3000 
and 3500 feet could see a rain/snow mix. High temperatures will be 
4-8 degrees above normal. 


Long term...Friday night through Wednesday...models remain in 
relatively good agreement through the extended period. Zonal flow 
will set up over the Pacific northwest over the weekend with a ridge 
of high pressure trying to build just off the coast that will shift 
the flow from westerly Friday night to northwesterly by Sunday. 
Decreasing probability of precipitation Friday night as a weak trough shifts to the east but 
the next round of precipitation will spread over the forecast area 
Saturday. Snow levels around 4000 feet Friday night and Saturday. 
Saturday night and Sunday as the flow aloft shifts to the northwest 
will see the best chance of precipitation over the region with snow 
level rising to around 6000 feet. Precipitation will slow decrease 
over the region from west to east Sunday night through Monday. 
Tuesday through Wednesday the forecast area will remain under a 
northwesterly flow with enough moisture for chance probability of precipitation in the west 
central and Boise Mountains and Baker County Oregon with the rest of 
the forecast area being mostly dry. Temperatures over the weekend 
will be a few degrees above normal but for next week temperatures 
will warm to around 10 degrees above normal. 


&& 


Aviation...widely scattered snow showers with areas of MVFR 
ceilings and local IFR conditions...mainly this morning...over Baker 
County Oregon and the west central mountains of Idaho. VFR 
conditions elsewhere under broken to overcast middle level ceilings. 
Surface winds will be 10 knots or less. Winds aloft will be south 
to southwest around 15 knots up through 10k feet mean sea level.

Boi watches/warnings/advisories...
