Area Forecast Discussion
National Weather Service Spokane WA
420 AM PDT SAT AUG 2 2014

.SYNOPSIS...
Very warm conditions will continue, with isolated to scattered
showers and thunderstorms through Sunday. The storms may result in
some localized heavy downpours and gusty winds. No significant
relief from the hot weather is forecast through the next seven
days.

&&

.DISCUSSION...
Today through Sunday...the threat of showers and thunderstorms
will continue through the weekend but coverage will be focused on
the rising terrain surrounding the Columbia Basin. A couple of
modest shortwave impulses will roll through the ridge over the
next 36 hours. Daytime instability will allow for increased
thunderstorm coverage with less of a threat during the overnight
hours. Inverted-V soundings indicate the possibility of
thunderstorms starting out dry with gusty outflow winds resulting.
The greater threat will be this afternoon when a better moisture
tap will be available. By Sunday the focus will be on the eastern
zones with less of a threat for the east slopes of the Cascades.
The ridge will remain essentially intact with temperatures
remaining on the above normal trend through the weekend. /Kelch

Sunday Night through Friday...The blocking pattern remains
across North America, with a deep low pressure system in the gulf
of Alaska and another cool for the season upper level low across
the Great Lakes. In between a strong ridge of high pressure has
been very slowly trying to shift east. This has put the Pacific
Northwest in a moist southwest flow the past several days.

By Sunday night and into Monday a weak ridge/split flow will
be across the Pacific Northwest. The deep sub-tropical moisture
will get turned off. However there will still be a couple of weak
impulses moving through the westerly flow and that will keep a
chance of thunderstorms in the forecast across the northern
mountains Sunday night. Then a few showers and possibly a few
stray lightning strikes on Monday across the Idaho Panhandle
mountains due to orographic lift and lingering mid level moisture.
Temperatures will rebound several degrees over Sunday and bounce
right back up into the mid to upper 90s.

Tuesday through the remainder of the week...The flow will be
mainly zonal (west-east) with a few weak waves tracking along the
Canadian border. There is not much in the way of moisture with any
of these waves and the forecast was kept dry for the time being.
By Friday a little deeper wave is showing up in the models, but
the timing is off by about 12 hours or more on the operational
models and will stay with a dry forecast. Each of the the
aforementioned waves will result in increased winds through the
Cascade gaps at times and this will have to be monitored for fire
weather concerns. Relative humidity will make a bit of a rebound
through the week from this past week, but will remain on the dry
side. /Tobin
