NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Spokane Washington 
346 PM PST Sat Feb 28 2015 


Synopsis... 
dry, seasonal conditions will found across the inland northwest 
this weekend. A weather system will pass through Monday into early 
Tuesday with the potential for light snow, especially for the 
Idaho Panhandle, with breezy conditions. Much colder air moves in 
behind this system, with temperatures well below average for the 
middle of next week. A dry period, with moderating temperature 
will follow for the end of next week. 


&& 


Discussion... 
tonight through Sunday night: a dry Continental air mass will 
reside over the region delivering mostly clear skies and seasonal 
temperatures. The region remains under broad northwest flow aloft 
with one disturbance well to the south and another tracking across 
through the Gulf of Alaska. Consequently, shortwave ridging will 
be the dominate weather feature through the remainder of the 
weekend. Winds are currently at their peak and will continue to 
wane this evening and overnight. Dew points are extremely dry 
with many locations reporting teens to single digits. As winds 
calm overnight, look for temperatures to rapidly cool with 
readings Sunday morning into the teens to lower 20s. Without 
sufficient mixing (i.E. Winds) returning Sunday, temperatures 
will remain cool but should recover back into the 40s...very close 
to March 1st normals. The aforementioned disturbance in the Gulf 
of Alaska will track into northwestern Washington late Sunday night with the 
potential for light snow reaching the Cascade crest by early 
Monday morning. Amounts through this period will be light with the 
potential for a few tenths after midnight but before sunrise. /Sb 


Monday through saturday: the next system drops across the Pacific 
northwest early in the week, with some snow threat and another 
shot of cold air, before milder and relatively drier conditions 
return. Between Monday and Tuesday night a couple mid-level 
shortwave dives across western Canada and the northwest United 
States. Models have been consistently in disagreement over the 
past few days over the evolution of the second wave, however this 
morning the wetter European model (ecmwf) trended toward the other drier guidance. 
One shortwave will be sliding south along the Washington/or coastline 
early Monday, bringing some shower chances to the Cascades early. 
A second shortwave slips by northeast Washington/north Idaho and Montana Monday 
afternoon into Monday night. This will ramp up precipitation 
chances across the eastern third of Washington and north ID, especially 
during the afternoon and evening. Overnight into Tuesday drier air 
comes in on the a north-northwest flow, with a weakening surface 
trough/deformation axis. There will be a lingering shower threat 
across the central Panhandle and Camas Prairie, as well as about 
the mtns of northeast Washington and north ID, but by this time the threat 
of significant precipitation will be ending. 


As for precipitation-type, snow looks predominant. However during 
the afternoon hours surface temperatures warming above freezing 
will limit the potential for accumulation outside of the 
mountains. Overall it still looks like about 1 to 2 inches in the 
eastern mountains and less than an inch in the valleys, if 
anything accumulates at all in the valleys that is. 


Behind the precipitation threat comes increased winds and that 
next push of cold air. In general, however, look for increasing 
northerly winds between Monday afternoon and Tuesday. The speeds 
abate through the Tuesday night. Tuesday afternoon temperatures 
are expected to be below normal by 5 to 10 degrees, followed by 
lows dropping some 10 to 15 degrees below normal Tuesday night in 
an atmosphere more conducive to good rational cooling (i.E. Dry, 
with few clouds and lighter winds). This means lows in the singles 
digits and teens Tuesday night/Wednesday morning. 


Between Wednesday and Saturday the rebounded ridge is eventually 
dampened again by another shortwave trough moving in from the 
west. The primary wave stays north of the Canadian border, but 
some weaker ripples do skim in on an the westerly flow. For the 
most part the forecast is dry, but a few isolated showers cannot 
be ruled out near the immediate Canadian border toward the end of 
the work week. The rebounding ridge is also accompanied by some 
milder air, so look for temperatures to moderate back toward 
normal and, by Friday, slightly above normal again. /J. Cote'
