NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Spokane Washington 
215 PM PDT Monday Apr 27 2015 


Synopsis... 
high pressure lingers through Tuesday, producing mild and dry 
conditions. However the approach of a cold front will lead to an 
increase in winds later Tuesday. Between Tuesday night and Thursday 
a passing system will bring more seasonal temperatures, breezy 
conditions and a threat of showers, followed by a general drying 
trend into the weekend. 




&& 


Discussion... 
tonight through thursday: the inland northwest transitions from warm 
and dry weather to cooler and breezy with shower chances, as an 
amplified ridge is replaced by a deep trough. Between tonight and 
Tuesday the ridge axis will be shifting east, while the trough 
axis advances to the coast. This puts the region in a mild 
southwest flow, with regional 850mb temperatures into the lower to 
mid-teens (celsius). This supports highs some 10 to 15 degrees 
above normal. The exception will be near the Cascades as the 
onshore flow and first shortwave rounding the parent trough brings 
a relative cool-down here. That shortwave will bring some clouds 
and a chance of showers to the Cascades crest too. The other 
region that may receive some isolated pop-up showers Tuesday 
afternoon will be across the northeast mountains, near the 
Canadian border, with steepening lapse rates and some marginal 
cape per some models. More likely, however, these factors will 
just lead to afternoon cumulus. The approaching trough will also 
lead to breezy conditions by mid to later afternoon as pressure 
gradients tighten between the two air masses. 


Tuesday night into Wednesday a second shortwave rounds the parent 
trough and helps propel a cold front and next best shower threat 
across the region. The first shower chances expand between late 
evening and Wednesday morning with the cold front passage. The 
highest threat will be near the Cascade crest in the early evening 
and expand east, especially across the northeast mountains, from 
late evening (11 pm) through Wednesday morning. The modest 
westerly and downslope flow should keep the precipitation threat 
to a minimum in the Lee of the Cascades. Outside of these areas 
there will be a modest threat of showers with the immediate cold 
front passage. However it appears the precipitation duration and 
amounts should be limited, because the front appears to pass 
relatively quickly. There is some elevated instability immediately 
along the front, indicated by a ribbon of 50-150 j/kg of MUCAPE 
between 850-500mb and similar ribbon of marginally favorable high 
level total totals, which swing into Montana by later morning 
Wednesday. So I wouldn't rule out some thunder or at least locally 
enhanced precipitation rates. 


Wednesday afternoon and Wednesday night the main upper trough and 
pool of colder air cross the inland northwest. The cold pool doesn't 
appear as intense as the one that crossed this past Saturday, but 
it should be enough to bring some threat of hit-and-miss showers 
and perhaps some isolated thunder during the afternoon and evening 
hours. The main risk will be around the mountains. However a few 
showers cannot be ruled out over the eastern Columbia Basin under 
the unstable trough. The risk wanes through the evening and 
overnight with the loss of daytime heating and a Flat Ridge 
nudging in from the west. Expect otherwise breezy conditions, a 
few clouds and temperatures cooling closer to seasonal averages. 


By Thursday models show a more zonal (west to east) flow over the 
region, with a secondary shortwave trough skimming by the Canadian 
border. In general look for some high clouds from the west- 
northwest, along with some afternoon cumulus. A slight chance of 
showers will also be found across the northern mountains, 
especially closer to the Canadian border. Otherwise conditions 
look mostly dry and seasonal temperatures. /J. Cote' 


Thursday night through Monday night: model consensus continues to 
advertise a dry zonal or westerly flow across the inland northwest with 
a few weak shortwaves rippling through at times. Each of these 
waves will bring some increase in winds, especially if the timing 
is late afternoon, but little in the way of precipitation with 24 
hour model trends continuing toward a dry period. Temperatures 
will hover just above seasonal readings topping out in the 60s to 
lower 70s. The GFS/European model (ecmwf) have backed off on a closed low early 
next week but do indicate more of an open trof and increase in 
moisture around midweek. Tough to buy into any solution given the 
wavering the last few days so at this time, will just hint at the 
potential for a few showers and potentially, another bout of wind.
