NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Spokane Washington 
455 am PDT Sat may 30 2015 


Synopsis... 
strong thunderstorms will be possible in the Idaho Panhandle and 
in the northeast mountains this afternoon; large hail, gusty 
outflow winds and heavy rain will be potential threats. 
Thunderstorm chances will lesson on Sunday and are expected to be 
more confined across the southeast portion of the forecast area. 
Meanwhile most locations will see very warm temperatures with 
highs in the 80s through the weekend. Thunderstorm chances will 
increase markedly on Monday into Tuesday as a strong upper level 
trough moves in from the south. Some of the storms on Monday could 
be strong and may produce large hail and strong winds. Unsettled 
and cooler weather will persist into the remainder of the work 
week with a threat of showers and thunderstorms each day.

Discussion... 


..isolated strong to severe thunderstorms possible in the central 
to northern Panhandle and northeast mountains this afternoon... 


Today: an upper level low pressure system will sit over central 
British Columbia. The eastern half of the region will remain unstable today, but 
the wester portion of the region will dry out as drier air pushes 
through the Cascade gaps. This will keep the active weather 
northeast of a line from Omak to Walla Walla. Much of the eastern 
portion of the region is very moist early this morning with p-wats 
up over 0.90 inches. Although these p-wats will see a slight 
downward trend through this afternoon, the atmosphere will remain 
moist across this portion of the region. There is a lot of cloud 
cover this morning with isolated to scattered showers and 
thunderstorms developing from the Okanogan Highlands down to the 
Camas Prairie. Much of these showers are very wet with heavy rain 
being observed underneath the stronger cores. These showers will 
keep the primer pumped for more afternoon thunderstorms in the 
afternoon. Dew point temps are expected to be in the mid 50s in 
the Panhandle and over the northeast mtns. Clouds are also 
expected to be clearing to the east by the late morning, which 
should allow for good surface heating. Models are indicating some 
impressive looking surface based CAPES of between 1000-2000 j/kg. 
There will also be a modest amount of shear of around 30 kts 
between 0-6 kms. Winds also will veer with height, which will help 
to generate some rotation with any thunderstorms that develop. 


There is a limiting factor for developing convection and that is 
there is no discernible kicker. In other words, there isn't a 
shortwave that will pushing across the region to help generate 
convection like what was observed yesterday. With the upper level 
low in central BC, it may be close enough to generate some weak 
divergence across the northern mtns. In addition, there will be a 
weak jet streak that sets up from northwest Washington to the central 
Panhandle mtns. This would also help to create some additional 
lift in the left exit region across the northeast portion of the 
region (albeit weak). With that said, surface based CAPES off of 
the models are strong for this portion of the region this time of 
year. There will also be little to no cin to overcome as well. 
This alone should be sufficient to get convection going. Some of 
these storm are expected to become strong and isolated severe 
thunderstorms is not out of the question. The primary hazard will 
be for large hail and gusty outflow winds. Heavy rain is also 
expected, but storms should also be moving at a decent pace to the 
northeast. This should limit the possibility for flash flooding 
impacts. 


Tonight into Sunday morning: convection should wane quickly with 
sunset. This will result in more benign weather overnight. There 
will be the possibility for some fog developing by early Sunday 
morning depending on how much additional rainfall is observed 
today. Best potential for fog would be in the northern Panhandle 
and in the northeast mtns. /Svh 


Sunday through saturday: Monday will be the potentially big wx 
day as far as thunder potential as a tongue of high Theta-E air 
surges northward ahead of the ejecting vort Max that will lift north 
up the Pacific NW coast. This conveyor belt of higher Theta-E air 
will provide favorable ingredients that will combine with the 
large- scale lift of the ejecting short- wave trough to 
potentially initiate strong thunderstorms that will expand NE 
through ern Oregon and into north Idaho and ern WA. Uncapped cape of 
500-1000 j/kg will combine with modest deep lyr shear of 20-30kts. 
This should be plenty sufficient to produce bands of embedded 
strong thunder comparable to what we saw last afternoon and 
evening...though farther east closer to north Idaho. Sref guidance 
also supports this slightly farther east corridor of highest thunder 
threat favoring hail and gusty winds. Tues, however, will be a 
tougher thunder fcst as most model guidance brings the low far 
enough inland that the deepest instability from Mon is quickly 
shunted east into wrn Montana. The tues through Fri period will 
resemble closely the wx regime we experienced earlier this week 
with the upper low overhead...with a resurgence of showers and 
thunder every afternoon where it's not already showering. There's 
no way we can get around broad-brushing this type of regime given 
the high level of confidence we have that pattern recognition 
supports the heaviest showers every afternoon. Bz 




&& 


Aviation...12z tafs: an unstable atmosphere this morning and 
afternoon will result in scattered to numerous showers and 
thunderstorms across northeast Washington and in the Idaho Panhandle. This 
threat will continue to exist near the kgeg, ksff and kcoe taf 
sites, especially in the late morning and early afternoon hours when 
surface heating increases. There is a lesser chance for 
thunderstorms in the vicinity of kpuw and klws taf sites through 
this afternoon, but confidence is too low to include in the taf as 
the capping inversion is expected to be stronger across this area. 
Thunderstorms will be capable of small hail, gusty outflow winds, 
frequent lightning strikes and torrential rainfall. /Svh
