NWS Forecaster Discussion

Area forecast discussion 
National Weather Service Pocatello Idaho 
209 PM MDT Tuesday Mar 31 2015 

Short term...tonight through Friday. 
Cold front has pushed through eastern Idaho with winds picking up 
substantially early this afternoon. Wind advisories remain in 
effect tonight with winds expected to continue after sunset and 
through Wednesday. Expect to see some blowing dust on roadways 
near plowed fields. May need another Wind Advisory on Wednesday as 
well. Precipitation should be limited to the central mountains and 
upper snake Highlands overnight with little snow accumulation 
expected. Will have much colder conditions Wednesday and Thursday 
behind the cold front with high temperatures actually below normal 
for a change. Snow showers will be possible both days mainly in 
the mountains with showers Thursday likely more widespread. Will 
see some light accumulations at high elevations the next two days 
but should generally be under 4 inches. Upper ridge pushes in 
Friday and expect widespread dry conditions with some warming 

Long term...Friday night through pattern 
expected through the extended as the ridge that had been a common 
feature over the western Continental U.S. Over the past several weeks breaks 
down. GFS...ECMWF...and their ensembles in reasonable agreement through 
the period...with GFS hanging onto the closed low a bit longer than 
the European model (ecmwf) early in the period which opens the closed low into a 
long wave trough sooner. Used a general GFS/European model (ecmwf) blend with a slight 
nod toward the GFS through the extended. Now for the details... 
Friday night through Sunday...region will reside beneath 
southwesterly flow aloft ahead of a closed low/trough that will move 
ashore early Sunday. What this means in terms of sensible weather is 
temperatures will moderate back to above seasonal norms by 5 to 10 
degrees on Saturday and Sunday. Moisture will increase Sunday ahead 
of aforementioned trough...promoting rain and snow shower development 
beginning in the central mountains Sunday morning with the upper 
snake Highlands and eastern Highlands getting into the act by 
afternoon. Well mixed boundary layer later Sunday into Monday will 
tap into stronger winds aloft as the jet core rounds the base of the 
trough...producing gusty winds especially in the Snake River Plain. 
Upper trough will slowly slide eastward Monday into 
Tuesday...promoting showers these days...particularly in the 
afternoon and evening as cold air aloft combined with early April 
insolation steepens lapse rates. Overall precipitation amounts 
through the period should be relatively light as precipitable water 
values remain generally at or below climatology for early April...with 
highest quantitative precipitation forecast of a couple of tenths of an inch...across favored 
southwest facing slopes with much less precipitation in valleys. Main 
changes were to increase probability of precipitation and sky cover slightly Monday and Tuesday 
across the southern and eastern Highlands. Temperatures under this 
regime will be up to 10 degrees below climatology early next week. Upper 
heights will build over the region by midweek in response to a 
deepening trough digging across the eastern Pacific...allowing for a 
temperature rebound beginning by midweek. 

Aviation...a strong cold front has passed through the region this 
afternoon with gusty southwest-west winds up to 30-35 kts developing 
at byi..Ida..and pih. Look for lighter southwest gusts up to 20 kts 
at ksun by 00z. Some slight reductions in visibility may also be 
experienced at pih and Ida with bldu. Winds should decrease some 
this evening into the 10-20 knots range. A secondary boundary moves 
through around 06z increasing winds into the 15-25kt range once 
again..with these persisting through the taf period at 
byi...Ida...and pih. Mainly VFR conditions expected through the 
period...however ceilings may approach MVFR towards 06z and continuing 
through the morning with vcsh...with the exception of byi. 


Pih watches/warnings/advisories... 
Wind Advisory until 3 am MDT Wednesday idz017-021-022. 

Wind Advisory until midnight MDT tonight idz019-020-032.
