NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Spokane Washington 
447 am PDT Sat Mar 28 2015 


Synopsis... 
today will be quite windy, especially in the morning. West winds 
of 15 to 25 mph with gusts over 30 mph will be common throughout 
the inland northwest with gusts as high as 45 mph over the 
Palouse. Showers will linger over the Idaho Panhandle through 
early this afternoon. The weather Sunday and Monday should be mild 
and relatively dry. Another fast moving front on Tuesday will 
bring more showers, wind, and onset to another few days of 
unsettled weather.

Discussion... 


..windy today with the highest gusts this morning over the 
Palouse... 


Today: a cold front will race eastward this morning. By sunrise 
most of the precipitation behind this front will clear eastern 
Washington with showers lingering in Idaho through early 
afternoon. Windy conditions are expected over most of the inland 
northwest today, especially this morning. 


* Winds: a Wind Advisory remains in effect for the Palouse and the 
Pomeroy area through 11 am. As of 2 am, the surface cold front 
extended from southern Alberta through northwest Montana into 
the southern Idaho Panhandle. Strong pressure rises in central 
Oregon had contributed to the tightening of the southwest 
gradient across Washington and north Idaho. As cold air 
advection steepens our low level lapse rates during the next 
couple of hours, momentum Transfer from 850mb and above will 
become more efficient allowing wind of 40 kts to mix to the 
surface in east and southeast Washington. The rising terrain of 
the Palouse, foothills of the Blue Mountains, and the Pomeroy 
area should experience the strongest winds under the core of the 
low level jet. The West Plains and Waterville Plateau may also 
experience gusts of 40 mph or more which will be close to 
advisory criteria. The highest gust potential will be this 
morning. By afternoon, low pressure will be racing through the 
Canadian prairies and our surface gradient will relax a bit. 
Breezy conditions will persist through sunset, but gusts should 
decrease into the 30-35 mph range by early afternoon. 


* Precipitation: the surface front has outpaced the mid-level 
front driving most of the rain showers. We have seen a marked 
decrease in the amount of lightning as deep low level cold 
advection has taken a bite out of our instability. Little more 
than a handful of lightning strikes are expected for the 
remainder of this event with the best possibility along the 
Canadian border under the 500mb cold pool. Snow levels will fall 
to 5000 feet by late morning leading to some light accumulations 
on the high peaks of the Idaho Panhandle and the Cascades above 
pass levels. 


Sunday: a Flat Ridge of upper level high pressure will develop 
tonight in the wake of today's storm. At this time, the models are 
in decent agreement that the core of the polar jet will be 
directed toward Vancouver Island and southern British Columbia 
Sunday and Sunday night. Low rain/snow chances have been retained 
along the Cascade crest mainly north of Stevens Pass Sunday along 
with a mention of a 20 percent chance over the mountain ridges 
along the Canadian border near Northport and Priest Lake. The 
remainder of the inland northwest should be dry with the most 
significant cloud cover (mid/high clouds) north of Interstate 90. 
/Gkoch 


Monday through thursday: the active Spring like weather will 
continue well into next week. Monday will be a transition day 
with mostly dry conditions as midlevel flow buckles to the 
southwest ahead of the next trof approaching. This will nudge any 
lingering cloud cover northward bringing a strong potential for an 
abundance of sunshine and mild temperatures across the region. The 
next upper-level trof will push into the region Monday night and 
linger through Thursday bringing several rounds of showers, gusty 
winds, and more seasonal temperatures. The first round of showers 
will accompany the leading cold front Monday night. Gusty winds 
will develop behind the front and persist into Tuesday. Meanwhile, 
the atmosphere will become increasingly unstable as the polar jet 
noses into southern Oregon and 500mb temperatures cool near -30c. 
A combination of forcing along smaller scale circulations (ie vort 
max), orographic ascent, and diurnal heating will promote numerous 
clusters of showers and possibly a few thunderstorms. Overall, it 
will be unsettled and showery but not the steady rains experienced 
on the 25th. Monday will be the warmest and driest day. Tuesday 
will be the windiest day with the potential for sustained winds 
15-30 mph and gusts in excess of 40 mph. Winds remain breezy 
through the week but not near the speeds expected Tuesday. 


Thursday night through saturday: the persistent trof lingering 
through Thursday will finally eject to the east as yet another 
deep upper-level trof near the coast. There should be a short- 
lived break as one system departs and the second approaches the 
coast but models are not in good agreement on the extent of this 
break. GFS has a break of roughly 6-8 hours before the next 
frontal system arrives thur nt into Friday. This has support from 
its ensemble mean but not the European model (ecmwf) which is roughly 24-30 hours 
slower. So timing is a bit sketchy at this time but model 
consensus is suggesting this will be another multi day trof and 
much cooler than the previous few largely in response to high 
pressure nosing into the Gulf of Alaska and drawing cooler air south 
through wrn Canada. As previously mentioned, numerous rounds of 
showers will be possible from a combination of elements but in 
comparison to the system for Tue-thur, snow levels will be lower 
for several days, thunder chances will be lower due to lack of 
charge separation, and graupel or snow could fall to some valley 
floors. In addition, look for temperatures to cool back several 
degrees below normal. We will be keeping a very close eye on this 
event with the potential for early freeze warnings. /Sb

Aviation... 
12z tafs: strong Post-frontal winds will impact the taf sites 
through mid to late afternoon today. West winds sustained 20 to 
25kts with gusts up to 35kts are expected with the highest gusts 
at kgeg and kpuw. Rain over the Idaho Panhandle will decrease to 
scattered showers between 15-18z. Mixing this morning should lead 
to improvement in ceilings, but a broken cumulus deck will likely 
bring a 2500 to 4000 deck back to Coeur D'Alene, Sandpoint, and 
possibly Spokane felts by 17-19z. Winds will diminish quickly with 
the setting sun. /Gkoch
