Area forecast discussion 
National Weather Service Pocatello Idaho 
247 am MDT sun Sep 7 2008 


Discussion...northwest flow pattern will push a weak shortwave 
along The Divide today. Moisture and instability will be limited 
over eastern Idaho and therefore expect on isolated showers along 
The Divide through midnight. A cold front will drop across the 
forecast area this evening and tonight which will kick up locally 
breezy conditions. Behind the front a Flat Ridge builds across the 
west and turns flow to a dry westerly direction. Latest models 
indicate that a closed circulation low drops south from Canada 
across the Idaho Panhandle into the Snake River Plain by Wednesday 
evening. The low slows and drifts east across the plain through 
Thursday night. This solution...which is similar in both long 
range models...is a drastic difference from earlier solutions 
which keeps the low well to our east. Confidence in model 
solutions is low at this time and therefore have introduced 
slight chance showers during this time frame rather than the much 
wetter footprint indicated. Hanko

Aviation...VFR conditions expected today with a few wind gusts to 
20kts possible at the taf sites.

Fire weather...northwest flow continues across the region. Red flag 
conditions are not anticipated at this time since wind gusts and 
relative humidity are expected to remain below criteria. Humidity 
values will drop significantly Monday as a short wave ridge builds 
over the area. However...winds are expected to remain relatively 
light. Red flag conditions could be met on Tuesday as a cold front 
approaches the area. Humidity will remain low but winds will pick up 
ahead of the front.
