NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service Pendleton or 
1035 am PDT Tuesday Sep 2 2014 


Updated aviation discussion 


Short term...update...a Gulf of Alaska system will swing across 
British Columbia and northern Washington today and tonight. This 
system will push a cold front across the region late this afternoon 
and this evening. Moisture with this system will be limited and will 
continue to mention varying chances of precipitation over the Washington 
Cascade east slopes through tonight. Will add a few showers to the 
northern Blue Mountains for tonight due to upslope affects. Winds 
will increase ahead of and behind the front. At this time the 
strongest winds should be across the Kittitas Valley due to the 
pressure gradients there and the proximity of the upper jet. Breezy 
to windy conditions will occur elsewhere, especially across the 
basin and in the Columbia River gorge. At this time expect some 
patchy blowing dust near open fields. Am currently uncertain as to 
how the winds will interact with the open field over the basin, but 
will have to monitor for possible lower visibilities in the blowing 
dust. Updates mainly keyed on winds and adjusting precipitation areas. 90 


Long term...previous discussion...dry split flow will remain over 
eastern Washington and Oregon for most of the long term period. This 
will keep dry and stable air over the area. Radiational cooling due 
to light winds...lengthening nights...and clear skies will keep 
nights cool while the amplifying ridge will provide sunny skies and 
warmer days. Sunday night and Monday an upper level trough with the 
main lift in Canada may drop far enough south to trigger some 
showers near the Cascades. The main effects will be another push of 
cooler air for late Sunday and Monday and some breezy conditions. 


&& 


Aviation...18z tafs...VFR conditions will be prevalent for the next 
24 hours. Skies will be mostly clear though few to scattered clouds 
will develop above 5000 feet above ground level this afternoon and evening as a 
cold front moves through the area. Skies will partially clear after 
15z tomorrow morning. No precipitation is expected except for a few 
showers in the Washington Cascades and north Blue Mountains. The 
main impact of the front will be windy conditions from late this 
morning into the early morning hours overnight. Wind will increase 
through the day reaching 15 to 25 kts with gusts to 35 knots in the 
late afternoon. Patchy blowing dust could impact visibility at kpsc, 
kpdt and kalw at times. Winds will drop below 15 kts from 05z-09z 
through 18z tomorrow morning. Perry 


&& 


Fire weather...a dry cold front will make it's way across the forecast 
area this afternoon. West to northwest winds will pick up and range 
from 20 to 25 miles per hour gusting to 35 miles per hour. Fire zones 639 and 641 will see 
the main force of these winds...with other zones in the 10 to 20 miles per hour 
range. Afternoon relative humidities should range from the lower 20s 
to lower 30s...with some isolated spots in the upper teens. Lowest 
relative humidity will be in zone 641 and an red flag warning has been issued for 
low relative humidity and winds. 89
