NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Spokane Washington 
245 PM PDT Thursday Jul 31 2014 


Synopsis... 
it will be partly cloudy and hot with isolated thunderstorms 
through the end of the week and into the weekend. No significant 
relief from the hot weather is forecast through the seven-day 
forecast period. However, only a few spots may reach the 100-degree 
mark. Isolated thunderstorms the next several days are not 
expected to be strong or severe but could bring localized heavy 
downpours. 




&& 


Discussion... 
tonight through friday: the mid-level ridge axis shifts east 
and the southwest flow begins to carry disturbances more directly 
into the inland NW, increasing the threat of thunder for some 
areas. Tonight one disturbance moving across northeast or tracks 
by southeast Washington and the southern Panhandle of Idaho. Interacting with 
the SBCAPE around The Blues and Camas Prairie into southeast 
Shoshone County, this will lead to the continued threat of some 
showers/T-storms largely this evening. The threat wanes with the 
loss of daytime heating the SBCAPE. However, a second and deeper 
disturbance was coming into southwest or this afternoon. It is 
projected to move northeast toward southern Washington overnight into 
Friday morning, then into Washington during the day Friday. 


First overnight into Friday morning look for some increasing 
clouds. The brunt of the available instability and deeper 
moisture, however, appears to remain south of our forecast area 
until after about 2 or 3 am. So overnight the main shower/T-storm 
chances will be over The Blues and over southwest Chelan County 
Cascades. There is also concern that some activity may develop 
over the lower Columbia Basin overnight and creep into the upper 
Columbia Basin early Friday morning. However confidence is low and 
pops will remain around 10 percent here. 


Going into Friday afternoon the SBCAPE reinvigorates around the 
mountain zones and secondarily toward the southeast Washington/lower Idaho. 
This includes the Palouse. With the aforementioned disturbance 
lifting in, this will bring a broader shower/T-storm threat about 
the mountain zones and southeast Washington going into tomorrow afternoon. 
General precipitation amounts are expected to be light, meaning a 
concern for dry lightning and fire weather concerns. With these 
factors and ongoing wildfires near the Cascades, a Fire Weather 
Watch was issued for the Cascades and Okanogan Valley, Waterville 
Plateau and Wenatchee area. Temperatures will remain well above 
normal and relatively humidity values remain low. There could also 
be an increase in winds near the Cascades with the increased 
onshore flow and cross-Cascade pressure gradient. /J. Cote' 


Fri nt through sunday: following the exit of the thunder-producing 
short-wave trough into srn British Columbia Fri nt, Sat through Sunday will be 
under the influence of a very slow moving upper trough whose pcpn 
will be highly terrain and diurnally driven. Large-scale forcing 
for ascent won't be very impressive with the main vort Max moving 
into ern WA Sat nt, shearing and weakening as it does. However, 
there will be a chance of nocturnal (overnight) showers or 
isolated thunder both Fri nt and Sat nt. The afternoon thunder 
threats will be located mostly across the Idaho Panhandle and NE 
WA. Based on the cape/deep lyr shear combo, widespread strong 
thunderstorms are not expected. New fire starts will potentially be 
an issue though. Bz 


Sunday evening through Thursday...subtle deamplification of the 
persistent long-wave ridge that has remained in place for quite 
some time takes place during this interval. The other persistent 
features such as the offshore trof/Gulf of Alaska low pressure 
area an another trof/low pressure area over eastern Canada remain 
in place as well helping to "lock" our long-wave ridge in place. 
The ridge axis remains generally in Montana for most of the 
interval which means there could be some clutter/disturbances/moisture 
coming up from the south or southwest off the east Pacific which 
could affect our sensible weather in the form of clouds and/or 
some thunderstorm potential. /Pelatti 


&& 


Aviation... 
18z tafs: VFR conditions expected the next 24 hours. Cumulus will 
develop over the mountains in the afternoon with cirrus moving in 
from the south through the late afternoon and evening hours. 
Isolated thunderstorm development is possible from the blue mtns 
to Lookout Pass this afternoon/evening. We will also have to watch 
for the potential for a few elevated showers coming into the upper 
Columbia Basin overnight into Friday morning, but the threat of it 
passing any taf sites is low. /J. Cote'
