NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Pocatello Idaho 
131 PM MST Sat Nov 22 2014 


Short term...tonight through Thursday. Strong zonal flow 
continues to stream into the Pacific northwest...with the bulk of the precipitation 
across the southern and eastern Highlands. Precipitation diminishes 
tonight to scattered mountain snow showers and isolated snow showers in 
the valleys. A few more inches of snow are possible in the mountains 
overnight...with around a half inch possible in the valleys. 
Strong winds will continue into the evening hours...diminishing 
somewhat by late evening. With the passage of the upper trough... 
winds turn to the northwest. With Pacific moisture still in the flow... light 
snow remains possible over the mountains due to upslope flow. Precipitation 
diminishes on Monday as upper ridging builds over the West Coast. 
Another minor wave in the northwest flow on Tuesday will bring more light 
snow mainly to the mountains hedges 


Long term...Tuesday night through next Sat night. 500mb long wave forecast 
indicates high amplitude ridge to remain in the eastern 
Pacific...keeping a mean northwesterly flow until the last 36 hours 
or so as the upper level ridge de-amplifies. So the first part of 
this period should be cold and somewhat dry...but the last 26 hours 
or so has a better potential of moist storms breaking down the 
weakened ridge and pushing through the Gem state. And that is 
exactly what guidance has...although the GFS brings in more 
precipitation in minor waves than a very dry European model (ecmwf). There is one 
exception. Early in the period...Tuesday night...a shortwave is 
finishing up just brushing eastern Idaho with some light to moderate 
precipitation that night...and the European model (ecmwf) is wetter. 


Thursday is the critical day as it is Thanksgiving. In either 
guidance product...it currently looks very good for southern 
Idaho...although travel through western Montana may have its 
problems. Expect dry conditions and probably the warmest day of the 
week. Messick

Aviation...two frontal boundaries expected to pass through today in 
the next few hours...making a complicated and low-confidence 
forecast. A brief break during the early evening wont allow much 
relief...but the second one will definitely turn ksun winds to the 
northwest and allow this airdrome to scatter out with little 
problems expected Sunday with strong subsidence and continued 
northwest flow. These fronts are definitely displaying their power 
as the southeast winds are occurring in the morning at ksun while by 
late afternoon they should have at least a westerly if not 
northwesterly component...the exact opposite of what happens on a 
sunny Summer day. But until the wind switch...ksun will be closed 
with snow and low ceilings. 


For the valley airdromes the heavy precipitation expected to 
continue at least until 23/00z. The marginal VFR ceilings though should 
continue long after that. And even later kbyi...kida...and kpih are 
all expected by the NAM to have IFR conditions once the wind 
subsides and the moist boundary layer cools during the overnight 
hours in time for morning opening. GFS and NAM are at odds on the 
ceilings...with the NAM being the usual pessimist compared to the GFS. 
With the abundant rain so far...and the better temperature 
verification this morning on the NAM...have decided to believe the 
ceiling crash for the morning hours. Finally...while wind is 
strong...little impact as it is right down the runways for the three 
valley airports. Messick
