NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Pendleton or 
230 am PST Friday Jan 30 2015 


Short term...today through Sunday. Water vapor imagery shows a weak 
upper low over the region. This system will move south today as the 
ridge builds back. There is widespread low clouds and fog over the 
forecast area and expect most of this to remain in place through the 
day. The upper low has lifted the stratus and fog just a bit so 
dense fog not much of an issue this morning as compared to the past 
several days. Very limited temperatures rise expected today due to 
cloud cover with highs in the 30s to lower 40s. The ridge will 
remain over the area Saturday with little change to the overall 
weather. The Columbia Basin and adjacent valleys will continue to 
have low clouds and fog with cool temperatures. May see some erosion 
of the low cloud cover in central Oregon though. A frontal system 
will be moving across the Pacific northwest Sunday with a chance of 
rain. Should be enough mixing with this system to start lifting the 
fog and low clouds by afternoon. 94 


Long term...Sunday night through Friday...the persistent upper 
level ridge over the Pacific northwest will gradually shift east to the 
intermountain region during the week which will allow a southwesterly flow of 
moist air to spread inland across the area. It will be mild with 
snow levels mostly above 4000-5000 feet and above 6000 feet by the 
end of the week. The wettest days look to be Monday...Thursday and 
Friday. By weeks end 2-3 inches of quantitative precipitation forecast are possible in the mountains 
and .5 to 1 inch in the lower elevations. This will be much needed 
moisture after a dry January. There could be a bit of a breeze on 
Tuesday with a better potential on Friday...although for Friday 
played it a bit conservative for now given that it is 7 days out. 
With the increased wind don't expect much in the way of Columbia 
Basin fog during the forecast period. 


&& 


Aviation...12z tafs...widespread MVFR/IFR ceilings and visibilities are 
expected through the forecast period. Stratus will be widespread but 
possibly clear out at kbdn and krdm this afternoon or evening. Some 
fog is likely this morning and again overnight tonight but not 
expecting widespread visibilities below 1-2 miles. A little drizzle will 
also be possible this morning. Winds will be light northerly. 78
