NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Spokane Washington 
451 PM PDT Monday Aug 3 2015 


Synopsis.... 
the ongoing drought, combined with high heat and low humidity 
will contribute to high fire danger throughout the inland 
northwest. Cooler temperatures and windy conditions are 
expected...especially Tuesday and Wednesday following the arrival 
of a cold front. Another threat of showers and thunderstorms 
arrives next weekend. 


&& 


Discussion... 


Tonight through tuesday: no significant changes to the fcst. 
Winds will continue to strengthen into early evening as pressure 
gradients strengthen...most notably near the Cascades (wenatchee 
region) and parts of the Palouse. Otherwise...a weak short- wave 
trough over Oregon will move NE and keep the threat of very light 
showers in the fcst for all areas outside of the Columbia Basin. 
Pcpn amnts should be no more than a trace for most towns due to 
unimpressive instability and a very dry sub-cloud layer below 
10-15k ft. Once this wave exits tonight, a cold front will move 
across the region and produce very gusty, but dry conditions 
tues.Bz 


Tuesday night through Friday morning: a low pressure system will 
begin continue to push into the region and shift the ridge of high 
pressure further east. The drying of moisture associated this 
system has decreased the chances of precip with this system. The 
areas with the chance of rain are the extreme northern Cascades 
and northern Idaho. With the decrease of the precip chances, the 
chance of thunderstorms has become next to nonexistent. The main 
concern during this period will be the afternoon winds. The 
thermal gradient is expected to tighten with the incoming system. 
The winds along the valleys in the Cascades are expected to have 
sustained around 20 miles per hour with gust near 35 miles per hour. Temperatures are 
expected to be near the normal with highs in the 80s. /Jdc 


Friday through monday: after a dry start to the period, a couple 
features move on the region. First low pressure lingering off the 
California coast is projected to make its way inland Friday and skim by 
southeast Washington and the lower Idaho Panhandle Friday night into Saturday 
night. Secondly a trough currently near the Aleutians moves toward 
the coast by Friday night and gradually makes its way inland 
through early next week, with impulses rounding it having 
opportunity to move across the Cascades and northern mountains, if 
not the entire region. There is disagreement on the strength and 
track of these impulses. Overall, however, this will lead to an 
increased threat of showers and thunderstorms across the mountains 
and potentially the valley/basin area. The risk will increase as 
the weekend progresses into early next week. Confidence is lowest 
around the valley/basin areas. Temperatures will warm into 
Saturday ahead of the trough, lingering near to just slightly 
above normal, before dipping again into early next week. We will 
also have to watch for another increase in winds Saturday, 
possibly combined with lower relative humidity values, for more fire weather 
concerns. /J. Cote' 


&& 


Aviation... 
00z tafs: a broad canopy of ceilings ranging from 9-14k ft agl 
associated with a weak wave moving NE through the area will 
produce only light amnts of rain. This pcpn threat will end first 
for the keat and kmwh taf sites (as well as klws/kpuw) around 
01-02z...then move out of the Spokane/ c'da area by 03-04z. As it 
does, expect west and southwest winds to gust to 25kt for all 
sites. These gusty winds will slowly decrease after 05z.
