NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Spokane Washington 
247 am PDT Sat Sep 5 2015 


Synopsis... 


A low pressure system will bring widespread rain and much cooler 
temperatures to the Idaho Panhandle and portions of eastern 
Washington Saturday. Light showers may linger mainly across the 
mountains Sunday and Monday. A drying and warming trend is 
expected next week. 




&& 


Discussion... 
today through sunday: rainy and cool conditions today will 
give way to isolated showers and somewhat milder conditions 
Sunday. From this morning to evening low pressure centered near 
the Washington/or/ID border tracks through Idaho and into western Montana. The 
trowal and moisture wrapped around the low will help bring rain 
across the eastern third of Washington and Idaho through the early afternoon, 
before the focus for precipitation starts to shift toward far 
northeast Washington and the Idaho Panhandle this evening. More widely 
scattered to isolated showers will be a threat toward the western 
Columbia Basin and Cascades today. However a second shortwave will 
be dropping in from the northwest and approaching the Cascades 
late tonight into Sunday morning, bringing a slightly better 
chance of showers there. That shortwave then pivots southeast 
across the remainder of Washington and north Idaho during the day Sunday. 
This relatively quick moving feature will have some moisture to 
work with, but it doesn't appear to be very deep. Instability 
exists but it is limited. In tandem with some moisture still 
wrapping around the backside of the exiting low, look for a threat 
of isolated showers over most locations. As for thunderstorm 
chances over the next 36 hours, there will be some risk but it 
will be limited. The best chances will be near the Cascades and 
over far north and eastern Washington and Idaho today, with the threat waning 
this evening after sunset, before being renewed across far 
northeast Washington and the northern Panhandle Sunday afternoon. 
Temperatures will be held back today across the eastern third of 
Washington and north Idaho under the rain and clouds, with many areas not 
getting out of the 50s. Milder readings are expected toward the 
western Columbia Basin and Cascades which will have more sunshine 
and less precipitation. By Sunday temperatures moderate across the 
region as the cold low exits. However values will still remain 
some 10 degrees below normal. /J. Cote' 


Sunday night through Wednesday night...although this period won't 
be as wet or cool as the beginning of the forecast it might not be 
as dry as it previously appeared either. The prevailing synoptic 
pattern for this period will feature a relatively Flat Ridge off 
the coast with west to northwest upper level flow over the inland 
northwest. This places the upper level jet somewhere near the 
Washington/British Columbia border through much of this period which results in 
several weak upper level disturbances tracking through the 
northern portions of the forecast area. Beginning on Sunday night, 
we should see a brief drying trend develop after the deep upper 
level low currently over the region shifts into Saskatchewan. 
There could still be some light showers during the evening mainly 
over the north Idaho Panhandle but little else. Then by Monday 
shortwave number one swings into the region from the northwest. 
The European model (ecmwf) and Canadian have consistently taken this feature into 
southeast Washington by midday, whereas the latest GFS leaves it near the 
NE corner of Washington. The 18z GFS showed this farther south 
track and will be the favored solution. Moisture with this system 
won't be terribly deep, nor will the potential instability, 
however given the orographic ascent expected to develop, 
especially over extreme NE Washington and the Idaho Panhandle, we 
will bring the chances of rain farther south than was previously 
anticipated. Most of the rain chances will occur north of I-90. In 
the Lee of the Cascades this system won't do a whole lot as the 
mean mid- level flow will favor moderate downslope regime. The 
next shortwave is expected to cross southern British Columbia on Tuesday. Model 
agreement with this feature is quite good, unlike yesterday where 
the GFS had the feature much farther north, which left the 
forecast area largely bereft of precipitation. Now most of the 
model solutions paint some light to locally moderate precipitation 
extending from the north Cascades to the Idaho Panhandle north of 
I-90. The heavier precipitation amounts are legitimate since this 
system will be briefly accompanied by a narrow precipitable water 
plume nearing an inch. Precipitation amounts could near a quarter 
inch across extreme NE Washington and the northern tip of the Idaho 
Panhandle with similar amounts possible near the Cascade crest. 
Meanwhile very little if any rain will fall in the Lee of the 
Cascades or the Okanogan Valley due to continued downslope flow 
off the Cascades. This feature should push east of the area on 
Tuesday evening. Wednesday will feature the last in the series of 
shortwave troughs. This one will be fast moving and fairly weak. 
Model cross sections show fairly limited moisture with most of it 
located above 12k feet so other than passing clouds we don't 
expect much precipitation at this point. Temperatures are still 
expected to warm through this period, however the trend will be 
slower than previously expected. Highs on Sunday will still be 
cooler than normal for this time of year with readings in the mid 
60s to mid 70s. By Wednesday temperatures should climb about 10 
degrees resulting in highs in the mid 70s to mid 80s, which is 
right around normal for this time of year. Fx 


Thursday through saturday: models are in very good agreement for 
this period. A dry zonal pattern is expected to dominate this 
period with some weak ridging build into the region. This will 
keep any chance of rain for the region close to non existent. 
Temperatures will continue to creep warmer with highs expected in 
the upper 70s to low 80s. Overnight lows will range from mid 40s 
to mid 50s. /Jdc 


&& 


Aviation... 
06z tafs: showers will drift north into extreme southeast Washington and 
central Panhandle of Idaho tonight along with isolated 
thunderstorms possible but confidence is low that any ts will 
affect a particular taf site. The wettest interval will be 
overnight tonight and into tomorrow as a wet frontal zone stalls 
over eastern Washington and north Idaho from about 09z on bringing 
MVFR conditions to taf sites except keat and kmwh. Kmwh will be on 
the western edge of the precipitation shield and may see very 
little rain. As the low moves east Sat afternoon, any breaks in 
cloud cover may allow convection to develop, with isolated 
thunderstorms possible across the forecast area. Cascade Gap winds 
will increase after 18z Sat with gusts of 25 to 30 kts possible at 
keat. /Ek
