NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Spokane Washington 
451 am PDT Sat Apr 19 2014 


Synopsis... 
following freezing temperatures this morning for most towns, another 
storm system will bring windy conditions this afternoon and night 
with some showers mainly for the mountain zones. Easter Sunday 
should be mild and mainly dry. After a warm and dry Monday, a cool 
and unsettled weather pattern will return Tuesday and linger 
through much of the week. 




&& 


Discussion... 
today through Sunday night: satellite imagery shows the next 
weather system approaching the region early this morning. A low 
pressure circulation is at approximately 140w/50n with an 
occluded front at around 130w heading toward the West Coast. The 
moisture source with this front can be located on water vapor 
satellite imagery by the band of elevated moisture content from 
160w/30n stretching to northern California. This moisture tap is 
shearing out and, as a result, will be a limiting factor for 
precip across the region as the front pushes through this 
afternoon. The front itself does have good structure to it and 
forcing aloft will be decent. Good cold air advection is expected 
as well. This will lead to a fairly tight pressure gradient 
developing behind the front. Winds will once again pick up this 
afternoon and the timing of the front will promote good mixing 
during as it will move through during the afternoon. 850 mb winds 
are only progged at around 30-35 kts. These magnitudes will be 
sufficient for solidly breezy to windy conditions, but advisory 
level winds are not expected. Expect sustained wind speeds of 
around 20-25 mph with gusts to around 35-40 mp. Strongest wind 
speeds will likely be on the Palouse and in the northeast blue 
mtns. These locations could see higher winds closer to 25 mph 
sustained with gusts to around 45 mph. A lack of moisture with the 
front will result in light precip and much of the lower elevations 
may only see some sprinkles, especially in the basin. Best chances 
for measurable precip will be in the mountains and in the Idaho 
Panhandle. The region will dry out on Easter Sunday as we will be 
between systems. Temperatures over the weekend will be near 
average for mid April. /Svh 


Mon through Wed: there are a number of challenges in this three- 
day period...leading to a lower than normal confidence level. Even 
with only one well-defined cold front and its accompanying upper 
trough passage, timing remains uncertain given the north-south 
shearing of the trough as it moves into the pac NW. Model guidance 
typically brings this type of trough onshore too fast three days 
out, so we still favor a slightly slower progression of the wave. 
That said, we lowered pcpn amnts into Mon evening with the initial 
frontal boundary. One of the biggest uncertainties concerns 
thunder chances Mon nt, mainly from elevated, non sfc- based 
instability above 700mb tied to a plume of moisture surging north 
ahead of the trough. A number of models show a narrow, but heavy 
band of pcpn tues morning close to this elevated instability and 
mid-level front. We continued with a broad-brush approach to this 
pcpn threat and did not add thunder attm. With the upper trough 
directly over the pac NW tues through Wed morning, not only will 
the pcpn be highly convective, but snow levels will fall 
markedly, leading to a significant snow and/or graupel 
accumulation threat. This will especially true for the Idaho 
Panhandle Wed morning under a developing trowal and Post-frontal 
upslope. It's likely that valley locations will see some snow with 
this scenario. Gusty Post-frontal winds will also be likely. Well 
below normal temps Wed looks certain for the Idaho Panhandle. Bz 


Wednesday night through saturday: parts of the inland northwest 
will be dealing with the departing trough Wednesday night/Thursday 
morning before brief ridging allows for slight lull in the 
precipitation. Any remaining precipitation Wednesday night over 
northeast Washington into the northern Idaho Panhandle will still 
have somewhat colder air to deal with, meaning snow at least in 
the mountains, and possibly into the higher valleys. Amounts 
during this period look like they'd be on the low side, so impacts 
would be minimal. 


Ridging shouldn't last as the next large scale trough approaches 
the Pacific northwest to close out the work week. This will bring 
more chances for precipitation most areas into the weekend. 


Temperatures will remain on the cool side of normal each 
afternoon, especially with the cloud cover that may never really 
clear out. The best chance, as of now, for more sunshine would be 
Thursday over the Columbia Basin. However, breezy conditions may 
result due to stronger winds aloft mixing to the surface. All-in- 
all, lots to look at for the far extended periods. Could be quite 
active. TY 




&& 


Aviation... 
12z tafs: a cold front is beginning to push into western Washington this 
morning. This front is expected to cross east of the Cascade mtns 
after 20z this afternoon and then quickly spread across eastern 
Washington and into the Idaho Panhandle. This front will generate mainly mid 
level cloud cover over the taf sites with some sprinkles possible, 
but will be dry for the most part. The main impact will be winds 
shifting from the east and northeast to out of the west and 
becoming gusty at the same time. Expect wind gusts up around 30-35 
mph with gusts peaking in the late afternoon and evening hours.
