Area forecast discussion 
National Weather Service Pocatello Idaho 
907 PM MST sun Jan 25 2015 


Update... 


Issuing a freezing fog advisory for the upper and lower snake 
plain from roughly American Falls to Idaho Falls. Satellite shows 
the high cirrus moving away from the area and a rapid increase in 
low fog and stratus over the snake plain. 04z observations and web 
cams show fog becoming dense and more widespread despite the 
little bit of wind out there. Looking at a trend that should 
support further cooling and lighter winds...one that supports fog 
even more...think that the fog will become more problematic as the 
night GOES on.

Previous discussion... /issued 155 PM MST sun Jan 25 2015/ 


Short term...tonight through Wednesday. Satellite imagery was 
showing a ridge of high pressure over the west with a cut-off low 
positioned along the Baja California coast. Low clouds and fog have plagued southeast 
Idaho over the last few days and I see no real game-changer in this 
regard until the ridge weakens and shifts east late Tuesday 
afternoon per the most recent guidance. As the ridge weakens and 
shifts east...the low off the Baja California coast will lift north through 
Nevada and across southeast Idaho Tuesday night. The main forecast issue 
appears to be snow levels as the upper ridges gradually warm over 
the next two days while cold air remains trapped in the lower 
valleys. As the low moves overhead Tuesday night...there should 
be enough mixing to wash out the inversions that have been 
supporting the low clouds...fog...and Cold Valley temperatures. 
There is a slight risk however that some pockets of Cold Valley air 
will remain...particularly in the Upper Valley...which would support 
the possibility of freezing rain sometime Tuesday night/Wednesday. 
We will continue to monitor that forecast element as the system 
draws near. Huston 


Long term...Wednesday night through next Sunday night. After the 
Tuesday night/Wednesday storm...skies should at least partially clear with 
high pressure moving in from the west. From about Friday Onward the 
operational European model (ecmwf) and GFS show much different solutions. The European model (ecmwf) 
shows a second shortwave moving up from the south...similar to the 
previous storm...but only making it as far as northern Utah before 
it heads eastward. The upcoming weekend on the European model (ecmwf) indicates a 
strong ridge with very high 500mb heights and warm air moving in. 
The GFS is fairly much the opposite. Very dry in the beginning...but 
in the last 24 to 36 hours of the forecast a trough moves in from 
the west. Lots of differences means low confidence forecast...except 
that even the GFS storm is not very powerful...so do not see 
anything headline-worthy during this period. Both the European model (ecmwf) and GFS 
have little in the way of wind. The GFS has much warmer...about 10 
degree f...than normal temperatures...while the European model (ecmwf) has near to 
slightly above normal temperatures for the extended forecast. The 
European model (ecmwf) solution is supported by the longwave pattern...but the upper 
level ridge doesnt have much amplitude so the GFS solution is not 
out of the question. Have continued downward trend in probability of precipitation and sky 
cover. Messick 


Aviation...high pressure returns after the weak winter storm of 
last night. The main forecast problem is what will the stratus do. 
The NAM boundary layer moisture indicates enough easterly flow to 
keep the north side of the Snake River Plain in stratus while the 
east/south side clears somewhat. On the other hand...MOS guidance is 
all for a return of the stratus. So this is a low confidence 
forecast for the valley airdromes...especially kida and kpih. Have 
left scattered stratus in the tafs...but believe that the boundary 
layer moisture forecast is better than the statistical MOS guidance 
for this season. Much more assured of good conditions at kbyi and 
ksun with nearly breezy conditions at kbyi keeping the stratus and 
fog broken up and northwest flow for the late night and morning 
hours at ksun pushing the fog back down into the Snake River Plain. 
With the building stratus on that side of the valley...do have a 
concern that ksun could get the stratus on Monday late morning or early 
afternoon if the southeast winds kick in...as they likely will.
