NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Boise Idaho 
850 PM MST Tuesday Feb 9 2016 


Discussion...upper level ridge is beginning to weaken and become 
less amplified over the western United States. Temperatures aloft 
will slowly cool tonight into Wednesday but still warm enough for 
an inversion to remain in place. Expect much of the same for 
Wednesday with stratus in the morning...slowly burning off during 
the day and reforming at night...except lingering in the lower 
Treasure valley and the Weiser river basin. Upper level cirrus 
tonight could hinder the development of stratus overnight in the 
upper Treasure valley. Will update the forecast tonight for less 
fog development as the fog has evolved more into a low stratus 
deck in the lower Treasure valley. Update out shortly. 


&& 


Aviation...high pressure aloft will maintain the temperature 
inversion for several more days. Patchy valley stratus and fog this 
evening will increase in coverage overnight. From about 06z to 21z 
expect areas of IFR and local LIFR stratus and fog...with tops near 
5k feet mean sea level. After 21z most stratus and fog will temporarily 
dissipate...but local obscuration of mountain slopes by remaining 
stratus is likely. Surface winds...variable mainly less than 10 kts. 
Winds aloft...southwest to west 10-20 kts through 10k feet mean sea level. 


&& 


Air stagnation...inversion still in place through at least 
Thursday as upper level ridge begins to weaken and shift 
southward. Expect a continuation much like today with little 
change expected as the 00z/Wednesday sounding still had a strong 
inversion around 5200ft mean sea level /or mixing height up to around 2300ft 
above ground level/. 


&& 


Previous discussion... 
short term...tonight through Thursday...inversion is locked in 
place in the valleys...with higher elevations much warmer today 
than even yesterday. This pattern will continue through Thursday...even as 
the higher elevations cool slightly each day as the upper level 
ridge weakens and moves east. Temperatures in the valleys are notably 
lower than all computer guidance...and much more manual editing 
was done today than usual. We expect the inversion-induced valley 
temperatures to remain fairly consistent day-day in the short term. 
Overnight lows should be higher than forecast...for the same basic 
reason. Low clouds extended from the southern portion of the western 
Magic Valley through the southern portion of the upper Treasure valley 
and into most of the lower Treasure valley. Coverage extended west 
and southwest into most of Malheur County and much of northern Harney 
County. The upper Weiser river basin and the valleys of Baker 
County were also covered. Some of this area will lower back into 
fog overnight...and may become dense. However...confidence on 
where this will occur is too low to issue a dense fog advisory at 
this time. A trough will approach Thursday...bringing middle- and high- 
level clouds to region. These will move in from west to east 
through Thursday. Some models are indicating the chance for light 
precipitation Thursday afternoon...but at this time we do not believe 
sufficient moisture will be in place for measurable precipitation. 


Long term...Thursday night through Tuesday...looking for stable 
conditions to persist into Friday due to an upper level 
ridge...therefore anticipating valley inversions to continue through 
Friday...however could be limited due to an increased southeast flow 
over the region. Upper level trough to move in late Friday into 
early Saturday followed by a moist northwesterly flow aloft through 
Sunday. Most of the region will see light precipitation over the 
weekend. Temperatures will increase in the valleys as the inversion 
breaks...to about 5 degrees above normal. Upper level ridge rebuilds 
beginning Monday...pushing the moisture plume to the north. The 
blue/west central/Boise Mountains could see light precipitation through 
midweek. The rest of the region should remain dry with increasing 
temperatures expected.
