Area forecast discussion 
National Weather Service Pocatello Idaho 
148 am MDT Tuesday Sep 2 2014 


Short term...today through Thursday. A dry but warmer day across 
eastern Idaho is on tap ahead of another cold front on Wednesday. 
We will be 5-10 degrees warmer this afternoon vs. Labor Day. It 
will be a bit breezy again this afternoon but we are not expecting 
any appreciable impacts related to wind for today. As the next 
system swings inland tomorrow...this will swing a cold front 
across the region. The NAM is several hours faster with it...but 
all models indicate that the front is out of here by afternoon and 
similar high temperatures will result. There will be more wind 
tomorrow...10-20mph sustained across the mountains and 20-30 miles per hour 
for the snake plain. We will likely need a lake Wind Advisory 
tomorrow. Also expect some blowing dust as late Summer plowing has 
begun...but any impacts to traffic and such should remain low. We 
despite a little bit of moisture arriving with this storm...we 
should remain dry. By Thursday...we end up with an elongated/split 
flow across the west stretching from southern Saskatchewan across 
the Idaho Panhandle and toward the California coast. We will 
likely see some clouds with a small increase in moisture...but 
once again we are not forecasting any showers or thunderstorms. We 
will continue to cool down with highs of 50s and 60s in the 
mountains and low/middle 70s for some valley locations. Keyes 


Long term...Thursday night through next Tuesday. Heading into the 
weekend...the models are still struggling a bit on where to place 
potential showers and storms despite a similar pattern 
evolution. We will the low along the coast become the dominant 
system...with high pressure building across eastern Idaho. This 
appears to be where the issue of lies. The GFS is a bit stronger 
with this ridge and develops precipitation across the north. The 
European model (ecmwf) is a little flatter and keeps anything across the 
south...especially near Bear Lake. We continue to split the 
difference and call for a slight chance across most or all of the 
central and eastern mountains. Temperatures will undergo a slow 
climb either way until about a week from now. The models are 
consistent on pulling another system across southern Canada and 
the northern U.S. At some point...we will see an increase in 
showers and storms across the central mountains and upper snake 
Highlands for sure. Depending on how far south the storm ends up 
being...we may see development across the rest of the eastern 
Highlands. Do expect another breezy period along with yet another 
cooldown. Keyes 


&& 


Aviation...dry westerly flow aloft will result in VFR conditions 
through tonight. Moderately gusty winds are expected this afternoon in the 
Snake River Plain. Hedges 


&& 


Fire weather...westerly flow aloft will result in dry and warmer 
conditions through tonight. Moderately gusty winds are expected this 
afternoon in the Snake River Plain. A dry cold front is expected to 
pass through Idaho Wednesday morning...bringing stronger southwest 
winds and cooler temperatures to the region. Isolated thunderstorms 
are possible over the weekend...along with warmer temperatures.
