NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Pocatello Idaho 
250 am MDT Sat Apr 19 2014 


Short term...today through Tuesday. Upper low circulating in the 
Gulf of Alaska will spin off a short wave into the Pacific northwest today. 
Models suggesting this may enhance surface cyclogenesis over the 
snake plain with the NAM advertising a stronger surface gradient 
late tonight into Sunday morning. Guidance is keeping wind speeds in 
the low 20 knots range peaking around 15z Sunday. We then see a brief 
transient ridge build into the area leading to fair weather. 


The upper ridge will shift eastward Monday as another shortwave 
trough spins into the Pacific northwest. As the trough enters Idaho...it will 
have a negative tilt and we should see showers spread across the 
region late Monday night and into Tuesday. Not enough confidence in 
the strength of the instability to include thunder...but enough 
moisture transport to start increasing probability of precipitation late Monday night. 
Hinsberger 


Long term...Tuesday through Saturday night. Models still on track 
with a deep upper trough moving onto the western US on Tuesday. This 
system is expected to produce widespread rain showers and isolated 
thunderstorms across the forecast area. Snow levels will be around 8000ft. As 
the storm system moves off to the east...precipitation chances begin 
diminishing in the valleys on Wednesday but remain higher in the mountains 
temperatures will also be much cooler...with snow levels dropping below 
5000ft. Thus may see some snow showers in the lower elevations on 
Wednesday. A strong Post frontal pressure gradient would indicate gusty 
winds on Wednesday. Upper ridging builds in for Thursday...resulting in drier 
conditions and slightly warmer temperatures through Friday. The next system due 
for the weekend is handled differently by the models. The GFS is 
faster with the upper trough than the European model (ecmwf). Will favor the European model (ecmwf) 
solution and only gradually increase precipitation chances Sat and Sat 
night. Hedges 
&& 


Aviation...shallow upper ridging today will result in VFR 
conditions through tonight. Hedges 
&& 


Pih watches/warnings/advisories...none.
