NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Boise Idaho 
845 PM MST Wednesday Nov 26 2014 


Discussion...evening satellite imagery shows a cold front just off 
the northwest coast but the front will dissipate before it can get here due 
to a broad upper ridge over the interior western U.S. Dry mild weather will 
continue in our County Warning Area through Thanksgiving day although skies will be 
mostly cloudy...especially in northern zones. A cold upper trough will 
come south through British Columbia Friday and Saturday...and our northern zones will 
definitely get quite a bit colder by Sunday. Models differ about 
whether the trough will reach our southern zones...GFS says no...ecm says 
yes...but recent model trends support the colder ecm. If the ecm 
verifies then a cold front will pass through our southern zones late 
Saturday with gusty winds and rain and snow showers...changing to 
snow showers Saturday evening. Afternoon forecast favored the colder 
ecm and we see no reason to disagree. 


&& 


Aviation...MVFR conditions in fog kmyl and vicinity. Otherwise VFR 
conditions with thickening and lowering clouds. Slight chance of 
rain and snow showers and mountain obscuration spreading into Baker 
County and the west central mountains by morning...increasing to a 
chance Thursday morning and spreading south to a kbno-kono-ksun 
line. Surface winds 10 knots or less. Winds aloft will be westerly 
20 to 30 knots up through 10k feet mean sea level. 


&& 


Previous discussion... 
short term...tonight through Friday...upper level ridge over the 
pacnw and Idaho brought mild temperatures /59 at Boise so far/ and 
considerable cloudiness. The upper ridge will flatten Thanksgiving 
day as a cold upper level trough across west Canada pushes south. 
Infrared satellite imagery shows a deep upper low over the southeast part of 
the Gulf of Alaska. To its south and east water-vapor and aircraft / 
satellite derived wind reports indicate a broad area of strong middle- 
level winds and rather moist conditions. This moisture will shift 
east and looks to affect north central to NE Oregon and central 
Idaho. The Canadian trough dropping south will increase middle-level 
winds for enhanced orographic lift. Deeper moisture and strong 
lift are poised upstream to the west while much colder conditions 
loom to the north. 


Long term...Friday night through Wednesday evening...as Friday 
night wears on...the area will continue to be in a moist southwest 
flow which will continue the upslope precipitation for the west 
central mountains through early Saturday. At the same time...a 
cold front will begin moving into the area from northwest to 
southeast. Current forecast times the cold front to be near a line 
from Burns to Baker around noon Saturday and be passing through the 
Magic Valley by Saturday night. Snow levels will be around 5000 to 
6000 feet mean sea level ahead of the front and drop to valley floors towards the 
end of potential precipitation...so major snow accumulations will 
likely exist only in the west central mountains. Clearing will follow 
the front and temperatures will drop...possibly 10-15 degrees...from 
Saturday to Sunday. While this cold front is working its way through 
the area...a cutoff low will position itself off the coast of northern 
California. Models are in decent agreement that this cutoff low will 
send a warm front through our area from south to north late Sunday 
into Monday. However...the GFS brings this front in about 12 hours 
sooner than the European model (ecmwf)...so uncertainty exists for many variables. 
For Tuesday and Wednesday...the area looks to remain in a fairly 
active pattern as that cutoff low begins to slowly move east...so 
forecast is close to climatology as timing is still unclear.
