Area forecast discussion...updated 
National Weather Service Spokane Washington 
1106 am PDT Friday Oct 10 2008 




..updated aviation... 


Synopsis... 
an unseasonably cool area of low pressure has developed over the 
northwest and will linger through the end of the week. Breezy 
north winds will overtake the region by midday today as cold dry 
air moves across the northern rockies. With the upper low now over 
the Great Basin moving slowly east the next 48 hours...the 
isolated rain and snow showers over the Lewiston and Camas Prairie 
region this morning will slowly decrease.

Previous discussion... /issued 939 am PDT Friday Oct 10 2008/ 
rest of today...the only updates were to adjust clouds and a few 
high temperatures. We'll keep an isolated rain/snow shower threat in the 
forecast for mainly the Camas Prairie of Idaho given the slow demise of 
precipitation on the regional mosaic radar as well as satlite trends. Low- 
level cold air advection and breezy north winds will accompany the passage of a 
coldfnt that should reach all of eastern Washington from the north shortly. 
We'll evaluate whether or not to issue a freeze warning for 
tonight for the Lewiston area. The warning looks like a good bet 
if ceilings scatter...which they should do by late tonight. Bz

Aviation... 
expect gusty northeast winds to increase steadily through this 
evening...and be the strongest around the kcoe taf and north toward 
the British Columbia border. Gusts to 30 miles per hour will be common before decreasing 
by middle-morning Sat. VFR ceilings now over the Palouse and Lewiston 
region are expected to diminish later today...and remain scattered 
overnight. Precipitation is no longer expected after 20z for klws or kpuw. Bz
