NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Spokane Washington 
433 PM PDT Friday may 22 2015 


Synopsis... 
the Memorial Day weekend is expected to be warmer than average, 
with afternoon temperatures in the 70s and 80s. Look for scattered 
showers and thunderstorms this weekend into next week. Some 
thunderstorms will be capable of producing heavy downpours and 
frequent lightning. 


&& 


Discussion... 


Tonight: we'll be dealing with short-segment lines of 
thunderstorms moving west off the higher terrain of north Idaho and 
into Spokane and the Palouse. The other area of concern is the 
potential for flash flooding/debris flows on recent 2013-2014 
burn scars. So far most of these scars have been missed by the 
heaviest rain rates in the Cascades. The devels Elbow complex 
south of Republic has, so far, received the most direct hit...but 
calls to local authorities have yielded no reports of debris 
flows. The cape/shear combo supports heavy downpours and small 
hail into this evening with any thunderstorms. We'll be doing 
nowcasts, facebook posts and twitter updates when time allows.Bz 


Saturday through monday: models are in pretty good agreement of 
where to track the upper level low that is moving down British 
Columbia and into the inland northwest this weekend. The low now 
doesn't push into Washington until Sunday evening/Monday morning. 
Until then...northeasterly flow into the northern Idaho Panhandle 
and northeast Washington will keep conditions dry with mostly 
clear skies. The main concern for showers and thunderstorms will 
continue to remain across extreme southeast WA, the central Idaho 
Panhandle and along the Cascades. Each afternoon and evening 
showers and thunderstorms will develop and then wane with the 
setting sun in the evening. Isolated showers is possible through 
the overnight and early morning hours for the aforementioned 
areas. Given we are expecting less shower activity and clouds 
Saturday and early Sunday, have increased Max temps about 1-3 
degrees. Sunday night/Monday the upper low will move into 
Washington. There are some model differences of where the low GOES 
during the day on Monday. Nevertheless the chance of widespread 
rain will increase. Monday looks to be the 'crummiest' day of the 
Holiday weekend. Have lowered Max temps a few degrees, as we 
looked to be the outlier compared to other forecast models. 
/Nisbet 


Monday night through friday: the inland northwest remains unsettled 
with some threat of showers and thunderstorms each day. Most 
models keep the region in a weak flow pattern with a mid-level low 
bobbling about the northwest United States at least through 
Wednesday. Thereafter models diverge, either holding the low near 
the northern rockies or showing a transition to a west-southwest 
flow with a low migrating down the British Columbia coast. Either way 
instability blossoms each afternoon, in the form of expanding 
cape. Precisely how much synoptic forcing there is and where it 
will lay will come into more focus as models come into better 
agreement. But for now look for a threat of showers and 
thunderstorms expanding each afternoon, then dissipating but not 
entirely ending for the night and morning hours. The threat will 
be best throughout the region through Wednesday. Thereafter there 
is some suggestion that the threat will retreat away from deeper 
Columbia Basin toward Thursday and Friday. Any of these 
showers/T-storms may contain the typical brief heavy rain and 
perhaps some small hail and lightning, but given the more 
convective nature of the system none of this is a definite for any 
one location. /J. Cote' 




&& 


Aviation... 
00z tafs: marjority of thunderstorms on the radar this evening are 
moving with a general storm track to the southwest at around 20 
mph. With loss of peak heating and limited dynamics to support 
forced convection the aviation forecasts show majority of 
thunderstorm activity gone from most taf sites after 2z and from 
just about everywhere at 9z Saturday. MVFR ceilings primarily from 
the rain shafts and the small hail from some of the storms. Wind 
shifts common through this evening due to all the outflow 
boundaries propagating out of all the thunderstorms. Tafs have no 
mention of shower or thunderstorm activity Saturday afternoon as 
considerably lesser convective activity is expected. /Pelatti
