Area forecast discussion 
National Weather Service Spokane Washington 
237 am PDT Tuesday Jul 28 2015 

with the exit of the storm system that brought scattered showers 
and thunderstorms to the area last evening a return to Summer 
conditions will commence today. A dry and increasingly hot weather 
pattern will persist through next weekend across the inland 


today through tonight... 
the synoptic pattern consists of a very potent upper low 
currently in eastern Montana rapidly moving north and east. In its 
wake, a zonal pattern is setting up over the Pacific northwest. 
Water vapor imagery early this morning depicts a shortwave rapidly 
moving into western Washington. The infrared is showing some 
clouds associated with this feature as well...with some mid to 
high level clouds being reported in southwestern British Columbia and western 

Closer to home, the last showers rapidly moved out of our domain 
overnight with mostly clear skies prevailing now. Temperatures 
cooled into the 40s and 50s across the inland northwest under the 
clear skies. Not seeing any observations indicating fog developed 
but wouldn't be surprised to see some patches early this morning 
in the northeastern valleys of Washington and north Idaho. 

The aforementioned short wave moving west to east across the 
region today is the only focus for potential clouds and light 
precipitation. So far, no precip is being reported west of the 
Cascades. Based on the higher resolution models indicating a few 
showers from this feature, decided to bump up pops slightly along 
the Canadian border. This feature quickly races to the east during 
the day...exiting north Idaho by afternoon. 

Behind this shortwave, any lingering mid and upper level clouds 
will scatter out on our way to another mostly clear night. The 
warming trend begins with temperatures rebounding to the upper 70s 
to lower 80s today and continuing that trend overnight with 
temperatures about 5 to 10 degrees warmer than this morning. 
Localized gusty winds along the Cascade gaps but otherwise, winds 
will be relatively light. /Ab 

Wednesday through Monday...strong and consistent model agreement 
exists for this period featuring a westerly flow aloft/Flat Ridge 
scenario through next weekend. The storm track will lay well to 
the north of the region and any seepage of monsoonal moisture from 
the south will likely be shunted off to the east before deepening 
enough to cause trouble anywhere but the farthest southeastern 
margins of the forecast area late in the week. A stubborn surface 
thermal trough will become established over the next few days in 
the Columbia Basin. All of these elements argue strongly for a 
return to deep Summer conditions across the forecast area with no 
chance of precipitation except over the The Blues and Camas 
Prairie area which may be brushed by the margin of any monsoonal 

Expect a gradual increase in daytime highs and sultry overnight lows 
as the week wears on...culminating with solid mid 90s at most 
locations and a few triple digits in the lowest elevations Thursday 
through Sunday at least. Relative humidities in the afternoons 
will be very dry...but there are no significant wind issues 
expected to cause any official red flag conditions. Way out on or 
about Monday some of the model guidance depicts the approach of a 
weak Pacific short wave. At this time this may create a slightly 
better chance of thunderstorms next Monday but moisture 
availability and model agreement on this scenario is too nebulous 
to justify changing the current continued dry and hot forecast. 


06z tafs: isolated showers lingering a bit past 6z Tuesday yet 
VFR conditions prevail. Decreasing clouds cover expected through 
the remainder of the night with some patchy fog and low clouds 
between 9z to 15z Tuesday, and evening this fog and low clouds 
will not be widespread enough to keep VFR conditions from 
prevailing through 06z Wednesday. /Pelatti
