NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Boise Idaho 
239 PM MST Thursday Nov 20 2014 


Short term...tonight through Saturday...another winter storm is 
on the way for late Friday into Saturday which will bring mountain 
snow and valley rain. Inversion weakening and even breaking in the 
lower Snake River Plain this afternoon. Temperatures in the 
western Magic Valley are in the 40s with upper 20s to near 
freezing in the Treasure valley. Expect clouds to remain over the 
region tonight as a split trough moves across region. Much of the 
energy will dive south of the County Warning Area tonight/Friday morning but the 
weaker northern piece of energy will move across our northern 
zones for a slight chance of showers in the mountains. Clouds will 
keep the min temperatures a little warmer than last night. Next 
Pacific storm system moving into the Pacific northwest late 
Friday and into southeast Oregon and SW Idaho early Saturday. Breezy 
southeast winds /10-20 kts/ should increased mixing which should 
break much of the inversion by Friday afternoon. All guidance 
continues to suggest temperatures will remain at or above 
freezing through Saturday afternoon below 5000 feet. Based on the 
current warming trend and 12z kboi sounding this forecast seems 
reasonable at this time. There could be some freezing rain early 
Saturday particularly in the lower Treasure valley where the 
remaining cold air could be trapped. Otherwise...the valley will 
see up to four tenths of inch of rain. The west central and Boise 
Mountains above 5000 feet will see 6 to 8 inches of snow with the 
mountain peaks seeing close to a foot of new snow. No headlines 
yet with the mountain snow totals just over advisory criteria. 
Temperatures on Friday will be in the low to middle 30s in the valley 
with Saturday expected to reach 40 degrees. 


Long term...Saturday night through Tuesday. Decreasing 
precipitation over the region Saturday night as the storm system 
that will move over the area Saturday moves southeast of Idaho. 
Another weak shortwave will move through the flow keeping slight 
chance to chance probability of precipitation over the region through Sunday night. By 
Monday ridge of high pressure will begin to push north just off the 
West Coast but will keep a moist northwesterly flow over the 
forecast area. Models differ on placement of precipitation for 
Monday through Tuesday so will keep chance probability of precipitation over higher 
elevations and slight chance probability of precipitation at lower elevations. Temperatures 
will remain below normal. 


Tuesday night through Thursday...the region will continue to be 
influenced by a cold northwesterly flow that will keep temperatures 
about 10 degrees below normal. There will be a chance of 
precipitation Tuesday night into early Thursday /mostly in the west 
central and Boise Mountains/ most likely in the form of snow. 
Conditions should dry out a bit by Thursday morning. 


&& 


Aviation...mostly VFR with broken middle level ceilings. Some 
uncertainty as to if fog will redevelop in some valleys 
tonight...but some lower valleys still have MVFR conditions late 
this afternoon due to reduced visibility due to haze and fog and 
expect these conditions to remain through the night. Surface winds 
will be light. Winds aloft will be southwesterly around 20 knots up 
through 10k feet mean sea level. 


Weekend outlook...another storm system will move over the forecast 
area Saturday. Higher elevations will see snow but still some 
uncertainty about precipitation type for the lower valleys. At this 
time thinking is that lower valleys will change to rain...but could 
see a brief period of freezing rain early Saturday morning. Can 
expect mountains to become obscured along with widespread MVFR and 
areas of IFR conditions. 


&& 


Air stagnation...inversion will weaken significantly on Friday 
and break Saturday morning. A Pacific storm is expected to come 
inland Saturday morning with gusty winds and plenty of mixing 
which should scour the inversion and greatly improve air quality. 


&& 


Boi watches/warnings/advisories... 
Idaho...none. 
Or...none.
