NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Spokane Washington 
714 PM PDT Wednesday Apr 16 2014 


Synopsis... 
a weak wave will continue to bring more showers to the inland 
northwest this afternoon and evening before tapering off overnight. 
A stronger system will result in widespread rain Thursday and 
Thursday night, with breezy conditions Friday. At this time the 
Easter weekend looks to be mild and mainly dry. Showers will be 
more prevalent for the first part of next week. 






&& 


Discussion... 


Tonight: the stratiform showers from earlier today has now 
transitioned to more of a convective regime as we move into the 
afternoon hours. This has resulted in more spotty showers versus 
the widespread nature we saw this morning. Some showers have 
produced brief periods of light to moderate rain, but totals have 
still remained light. As we continue into the afternoon and early 
evening hours I expect the showers to move to the NE being confined 
to mainly the NE mountains of Washington and the Panhandle by this 
evening. With convective parameters weak, the showers will come to 
an end rather quickly this evening as sun sets and the atmosphere 
stabilizes. This evening into tonight will bring a brief break in 
the action as we have some weak ridging in place. Although clouds 
will remain firmly in place, the chances for precip diminishes. 


Tonight features the mentioned break period as we await the 
arrival of next system set to move in tomorrow. The precip looks 
to move from west to east reaching the Cascades early Thursday 
morning. This system looks to be much moister than the one today 
leading to a much better chance of widespread precipitation 
Thursday. Temperatures tonight will remain milder than last night 
as cloud cover will limit radiative cooling. /Fliehman 


Thursday to Friday night: precipitation comes to the inland northwest as 
a strong frontal wave migrates across the region through Thursday 
night. This is followed by more showery and breezy conditions 
Friday. 


First Thursday morning a warm front is draped across the region, 
while the cold front and it supporting upper wave approach the 
coast. Weak to moderate isentropic ascent in the 290-300k layer is 
directed across the eastern third of Washington and north Idaho. Initially 
condensation pressure deficits show the best saturation and 
highest precipitation chances lay over northern mountains and 
Cascades. However between 8 am-12 PM the atmosphere begins to 
saturate further south. The system taps a subtropical moisture 
plume, with pwats rising to 0.60-0.80 inches (or about 180-240% of 
normal). This will lead to a gradual expansion of in precipitation 
across the basin. Initially precipitation looks light, save for 
near the Cascade crest and perhaps the northern mountains. The lc- 
valley toward the Camas Prairie and possibly lower Shoshone County 
may remain dry. 


Then between later Thursday afternoon and Friday morning the cold 
front moves from the Cascades to the western Montana, with the 
supporting upper wave on its heels. This is when the highest 
precipitation chances and amounts develop, with deep-layer lift 
coming to the 850mb-500mb layer. There are lingering model 
differences as to how quick the front and upper wave pass. This 
has implications on how quickly precipitation decreases from the 
west, I.E. Toward late evening or not until the later overnight 
hours going into Friday morning. Either way much of the region 
stands a pretty good chance of seeing wetting rains (over a tenth 
of an inch). Some areas may pick up between 0.30 to 0.75 inches of 
rain, especially northeast Washington and the Idaho Panhandle and the 
Cascades. 


There is a thunder potential with this system too. In the late 
afternoon and evening hours models shows some uncapped cape across 
the upper Columbia Basin through northeast Washington mountains, with some 
negative dtheta/dz lapse rates. Overnight into Friday this shifts 
to northeast Washington and north Idaho overnight. Confidence is low with 
regard to the available potential instability. However a pocket of 
-20 to -25c 500mb come across the region and the system has 
impressive lift. So I added a slight chance of thunderstorms 
across these areas. 


Temperatures are expected to be held back by the clouds and 
precipitation Thursday, with highs expected to be below normal. 
Temperatures in some areas may struggle to get to the 50. Winds 
will also increase through by Thursday afternoon and remain in the 
breezy category through the night, thanks to the increased 
gradient and mixing with the incoming system. 


From Friday to Friday night a trough trailing the exiting system 
sags across the northern rockies. With low-grade cape and 
marginally negative Li values across northeast Washington and north Idaho in 
the afternoon and very early evening, in conjunction with a core 
of colder 500 mb temperatures around -28 to -30c), this will mean 
the threat of isolated to scattered showers. The modest mixing and 
still tight gradient behind the exiting low will also mean breezy 
to locally windy conditions. Depending on how much rain falls 
prior to this period, these winds could lead to some blowing dust. 
The best threat will be out toward the deeper basin, where lighter 
rainfall amounts are more likely with the Thursday system. 
Otherwise look for a mix of sun and clouds, especially in the 
afternoon. The overall shower threat and breezy conditions will 
abate rapidly after sunset. I did add a few areas of patchy fog 
overnight into early Friday morning across the sheltered mountain 
valleys across northeast Washington and north Idaho. The recent precipitation 
moistening the bl and low level high pressure stretching across 
this region will bring this threat. Temperatures will remain 
slightly below normal. /J. Cote' 


Saturday through Wednesday...a ridge of high pressure will bring 
dry conditions to the region on Saturday then a shortwave trough 
will move across the northern tier with a chance of showers north 
of Interstate 90 early on Sunday. For the start of the work week 
the region will be in moist southwest flow aloft that will keep 
unsettled weather in the forecast through Wednesday. Southerly 
flow will allow temperatures to remain on the warm side of climo 
through Monday, then an upper low will move over the region with 
cooler and showery weather expected through midweek. /Kelch 


&& 


Aviation... 
00z tafs: the weak weather system is continuing to move through 
the eastern Washington and Idaho Panhandle, bringing low cloud 
decks and rain showers to most of the locations in these areas. 
Cigs in these areas are hovering around MVFR and will continue to 
as another more moist system moves into the region around 18z and 
bringing rain showers to the inland northwest. A break in the 
rainshowers is expected for the late evening, early morning hours 
as dry low level air makes a brief appearance between the two 
systems. /Jdc
