NWS Forecaster Discussion

Area forecast discussion 
National Weather Service Spokane Washington 
258 am PDT Thursday Apr 24 2014 

occasional precipitation chances, breezy conditions and relatively 
cool temperatures dominate the weather pattern. The next organized 
storm system will bring periods of rain Thursday morning, 
followed by a threat of scattered showers and thunderstorms 
Thursday afternoon. Showers will remain a threat into the weekend, 
before a relative lull comes for the start of the new work week. 



..potential for a few strong thunderstorms Thursday afternoon... 

Today and tonight: the inland northwest transitions from a stable 
to a convective precipitation regime, before the threat of showers 
wanes after dark. A warm front and its stable precipitation will 
continue to shift into northeast Washington and the Idaho Panhandle this 
morning. Yet an occluding cold front and accompanying mid-level 
shortwave will be coming east of the Cascades between 15-18z (8-11 
am), before advancing east-northeast into north Idaho between 18-00z 
(11 am-5 pm) and eventually out through Montana tonight. This will keep 
the precipitation threat high over the eastern third of Washington and 
north Idaho through the day, before starting to dissipate after about 
00-03z (5-8 pm). Precipitation turns more showery over central Washington 
westward to the Cascades before dying out with the loss of daytime 
heating. Overall for this morning models place the higher 
precipitation amounts across the eastern third of Washington and the Idaho 
Panhandle. By afternoon models place the higher quantitative precipitation forecast amounts over 
northeast Washington and north Idaho Panhandle, along and north of a line 
from Davenport to Kellogg. However all areas will have a risk for 
periods of locally heavy rain with instability and a thunderstorm 

So yes, in addition to the generalized precipitation threat, there 
will be potential for thunderstorms and some of these may be 
strong. From near midday through early evening models show 
convective instability blossoming. A swath of 200-500 j/kg of 
cape and Lis between -1 and -3c across the upper Columbia Basin 
around 18z (11am) shift toward the eastern third of Washington and north 
Idaho between 21-00z (2-5pm). A potential limiting factor in the 
coverage and strength of storms will 0-6km bulk shear. This is 
favorable early today, with values between 25-40kts. However 
toward midday this more favorable shear shifts south, mainly 
impacting far southeast Washington and the central Panhandle. Still this 
is enough to be concerned that more organized storms are 
possible, especially in this area. With a low level jet around 25-35kts 
feeding into southeast Washington and the central Panhandle and the 
aforementioned instability, any organized storms will be capable 
of strong winds, some hail and heavy downpours. With all these 
factors I increased the thunderstorm chances from slight to chance 
this afternoon across east-central and southeast Washington and the 
central and southern Panhandle. The best threat appears between 
21-00z (2 to 5 pm). 

Aside from the precipitation threat the passing front will 
increase the pressure gradient and mixing, leading to breezy and 
locally gusty winds. Temperatures are expected to be near or 
slightly below average. /J. Cote' 

Friday through Sunday...the weather over the inland northwest will 
continue to be subject to the whims of a deep upper level trough 
which is expected to hang around through the weekend. Despite its 
presence...the weather isn't expected to be as wet as what we will 
experience today and tonight as there are no signs of a sub- 
tropical moisture intrusion. 

For Thursday night and Friday the models are in good agreement 
that the 500 mb trough axis will shift onto the coast which 
should transition the mid-level flow to a southerly orientation. 
Just how much precipitation this will result in isn't 
certain...but there quite a bit of model consensus that much of 
the region will be least through the late morning hours. 
The exception could be over the southeast corner of Washington and the adjacent 
portions of the Idaho Panhandle. This is the location where 
moisture from todays system could remain fixed as the negatively 
tilted shortwave pushes through to the northeast. Whether it 
remains fixed there or farther south through Friday morning isn't 
certain but there is a good chance that it will work its way back 
to the north during the afternoon as the mid-level flow backs 
toward the south. This will spread a high threat of stratiform 
precipitation across the Idaho Panhandle south of i90 with a 
lesser chance north. Across the remainder of the forecast area we 
will likely see diurnal heating lead to convection as lapse rates 
fall in advance of the 500 mb cold pool. Unstable conditions are 
not expected to be deep enough to trigger thunderstorms...but some 
could near the Cascades as 500 mb temps drop to near -30c late in 
the day. 

For Friday night and into early Saturday trof and 500 mb cold 
pool will shear apart as the longwave pattern is undercut by a 
strong upper level jet cutting through the desert SW. This will 
still leave the stratiform rain shield fixed over the Idaho 
Panhandle and the western portions of Montana. The chances for 
measurable precipitation will decrease steadily from east to west 
across the eastern half of Washington. By afternoon the approach 
of a minor shortwave trough from the southwest could wrap some of 
the Idaho moisture into the NE corner of Washington. Precipitation 
totals from Friday night into Saturday could be appreciable over 
portions of the Panhandle with readings nearing a half inch or 
slightly more over SW facing slopes. Snow levels will generally be 
above 4500 Mullan Pass could see some appreciable snow. 

For Sunday the base of the trough is expected to retreat to the 
north and it will gradually be undercut by moist west-southwest 
flow. This will result in an increasing precipitation threat 
beginning Sunday morning over SC Washington and gradually 
spreading northeast across the remainder of the region during the 
afternoon and evening. This could be the last batch of widespread 
precipitation as the extended models are all hinting at an 
amplifying ridge beginning to develop by Monday and persisting 
into Tuesday and beyond. Fx 

Tuesday night through thursday: models have come into better 
agreement concerning the middle of next week placing the inland northwest 
in a Dry Ridge pattern. By Tuesday night the ridge looks to be 
firmly in place pushing the storm track to our north and leaving 
our region in a stable, dry pattern. With the ridge overhead we 
can expect clearing skies, warming temps and light winds. The 
biggest question of this time frame currently is how high the 
temperatures get throughout the daytime. Right now the models 
have pegged next Thursday as the warmest day, but disagree on how 
warm. With the strength of the ridge, the region will likely 
approach the warmest temps we have seen so far this year. An easy 
way to sum up this period would be...very pleasant. /Fliehman 


06z tafs: steady rainfall continues to build northward through the 
Columbia Basin with most terminals expecting pcpn by 08z. Cigs 
will gradually lower and pcpn bcmg moderate temporarily as a cold 
front presses through btwn 15-18z. The frontal passage will mark 
the end of the steady rain and promote incr winds. A brief break 
is possible however a destabilizing atmosphere will lead to widely 
scattered -shra through late aftn with a good potential for isolated 
thunderstorms. NAM/GFS indicate enough instability setting up btwn 
mwh-geg-Coe to include vcts with the 06z issuance. Any storms will 
have the potential for small hail and strong wind gusts. /Sb
