NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Spokane Washington 
253 am PDT Monday Sep 1 2014 


Synopsis... 
today will be the mildest and least breezy day of the Holiday 
weekend. Temperatures this afternoon will be in the 70s under 
mostly sunny skies. The arrival of a cold front Tuesday afternoon 
and evening will bring a return of breezy to windy conditions and 
below average temperatures for Wednesday, along with some threat 
of showers and thunderstorms. A warming and drying trend is 
expected Thursday into next weekend. 




&& 


Discussion... 
today and tonight: fairly benign weather pattern as we transition 
over onto the stable side of the upper level jet. A little bit of 
fog is expected in the morning for the valleys in the northeast 
mtns and in the northern Panhandle. High temperatures will be a 
few degrees warmer compared to yesterday, but will still be 
slightly below normal for the beginning of September. 


Tuesday and Tuesday night: a dynamic weather system will push into 
the region out of British Columbia. This system will drop down on the tail end 
of the polar jet streak which will shift northeast across the 
region today. Strong upper level dynamics will produce a 
deepening surface low that will traverse the eastern edge of the 
Great Divide. The cold front associated with this system will push 
across the region during the late afternoon and evening hours. 
Good cold air advection should allow stronger winds aloft to mix 
down to the surface as the front pushes through even as we head 
into the evening, which is typically when winds would start to 
weaken. Winds up at 850 mbs will be up around 25-30 kts. This 
will translate into sustained wind speeds of roughly 18-22 mph 
with gusts up around 30-35 mph. Due to the southwesterly track to 
this system, winds are expected to be quite windy down the 
Okanogan Valley as well as through the Cascade gaps. Then these 
winds will filter out over the basin through the evening with 
frontal passage. The 06z NAM has also come in a bit more unstable 
and is more supportive of thunderstorms. Best chances for showers 
and thunderstorms will be across the northern mtns, but chances 
will extend as far south as the upper portions of the basin and 
the northern portions of the Palouse. The track of storms will 
generally be east to southeast with the northern mtns of Washington seeing 
convection first Tuesday afternoon and then transitioning into the 
Panhandle into Tuesday night. Thunderstorms will provide the 
potential for even stronger outflow winds that could enhance the 
synoptic scale wind speeds mentioned previously with gusts closer 
to 40-50 mph possible near convection. /Svh 


Wednesday: the potential for showers and thunderstorms will be the 
primary weather concern for Wednesday as a positively tilted 500mb 
trough lingers over north Idaho. It appears that the trough will 
be undergoing a split on Wednesday with the most substantial 
synoptic scale forcing shearing into southern Alberta and 
Saskatchewan. The 0z European model (ecmwf) and 6z NAM dig the 500mb cold pool 
into north Idaho and eastern Washington a bit more aggressively 
than the GFS. The weather prediction center favors the deeper 
solution over north Idaho, so a good chance of showers and 
thunderstorms has been retained for places like Sandpoint, 
Kellogg, Priest Lake and Northport. Elsewhere, limited deep layer 
instability and marginal mid-level lapse rates suggest low chances 
for convection. Wednesday should be the coolest day region-wide 
under the upper level cold pool with afternoon highs in the mid 
60s to mid 70s. 


Thursday and friday: a split flow pattern is expected to develop 
over the Pacific northwest Thursday and Friday. A weak upper low 
will likely develop near northern California as the southern 
polar branch sags southward. The northern branch will be much more 
vigorous and Cut Through the northern/central Canadian prairies. 
Washington and Idaho will be squarely between the two branches of 
the jet, and left mainly dry. Look for a gradual warming trend 
over the second half of the week into the weekend. /Gkoch 


Saturday through Monday night: a warming and drying trend will 
continue into the weekend over the inland northwest, with above 
normal temperatures expected. However, yet another trough will 
bring cooler temperatures and increased chances for precipitation 
early next week. 


Weak ridging will nose its way over the region Saturday and 
remain there on Sunday before another trough traverses the area 
Sunday night into early next week. The ridging will suppress any 
chances at precipitation, while also allowing temperatures to rise 
into the upper 70s (east) to mid/upper 80s west. 


Sunday night or Monday, a trough will beat down the ridge, and 
move over the region, cooling temperatures back to seasonal 
normals and increasing precipitation chances. Right now, the 
precipitation chances look to be confined to the higher terrain of 
the Cascades and the mountains of northeast Washington and the 
Idaho Panhandle. TY

Aviation... 
06z tafs: a few light showers will linger tonight north of the 
taf sites around Bonners Ferry. There has been a concern for 
stratus to redevelop tonight around ksff/kcoe however dew points 
are running around 6 degrees lower at Spokane and Coeur D'Alene 
compared to this time yesterday. Also NAM model shows a drier 
boundary layer tonight and thus a MVFR stratus deck does not 
appear likely for any of the taf sites. Up near the Canadian 
border around Sandpoint and Bonners Ferry a bit more low level 
moisture exists where a MVFR stratus deck is possible Monday 
morning. Jw
