NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Pocatello Idaho 
317 am MST Monday Dec 22 2014 


Short term...today through Wednesday night. Will allow winter storm 
warnings to continue through to their expiration time...then only 
light snowfall expected today at most high elevations. Clearing 
should develop during the evening and high pressure will continue 
the clear skies and colder overnight lows through Tuesday/Tuesday 
night/Wed. On Wednesday night...also known as Christmas evening...a Pacific 
storm is moving in to bring a messy low elevation rain/snow and 
high elevation snow event that continues into the medium range 
forecast. 


But the main forecast concern continues to be the wind. Local wind study 
indicates a re-development of advisory level conditions in the 
eastern Magic Valley and lower Snake River Plain. 40kt winds at 
700mb, 80-plus knot wind at 500mb, and 150-plus knot wind at 250mb 
are the main supporters. The mslp gradient does not strengthen 
until the afternoon...but it gets at least in the strong category for 
that period. The other contributing factor will be strong cold 
advection during the afternooon. Only concern is the northwest 
airflow for a direction and the stable conditions. Have included 
south Central Highlands as well. Messick 


Long term....long term...Thursday (christmas day) through next Monday. The 
GFS/European model (ecmwf) showed modest agreement on the main themes impacting the 
long term this morning although there were some striking variations 
on timing and track. The models agreed that a fairly significant Pacific 
trough would sweep into the region sometime Wednesday night/Thursday 
and exit to the east Friday morning. The GFS was a bit slower with 
the progression here and the main forecast adjustment was to begin 
to ramp up the probability of precipitation Christmas day. The 
chances of seeing snow in the Snake River Plain are looking better 
although snow levels start out fairly warm ahead of the advancing 
trough and then drop to valley floors as the precipitation begins to 
play out Thursday afternoon/eve. By Saturday...the models were 
showing the next Pacific storm system advancing into the region. This 
time...the GFS showed a more progressive/faster solution with the 
through sweeping into the northern rockies by Saturday afternoon whereas 
the European model (ecmwf) placed the trough along the coast. Given the spread in 
timing and track on this particular feature...have only nudged the 
chances of precipitation higher until the models come into better 
agreement. Huston
