Area forecast discussion 
National Weather Service Spokane Washington
927 am PDT Friday Aug 29 2014

Synopsis...
the Labor Day weekend will be cooler than normal with locally
breezy conditions over portions of central and eastern
Washington. With the exception of some isolated mountain showers,
the majority of the inland northwest will remain dry through the
weekend. A continuation of the cool weather pattern is expected
through next week. The best chance for showers and thunderstorms
will probably occur in the Wednesday or Thursday time frame.

Discussion...

Rest of today: the issues will be thunder chances, gusty Cascade
Gap winds, and cloud-cover/temps. The frontal passage today (visit
the radar mosaic along the olympic peninsula attm for frontal pcpn
band), should present the main focus as gusty winds as pressure gradients
increase across the Cascades. However, these gradients may be a
bit less if cloud cover in the Columbia Basin helps to limit the
high temps we currently have in the fcst for today. This will be
monitored. Wind advsys are not expected (gusts to 45 mph). We have
a slight chance of rain showers across the nrn WA and Cascade
zones later today, though with hourly pcpn rates from a trace to
a hundredth attm near Seattle, only very light amnts are expected.
For thunder, it doesn't look like there's much chance at
all...especially with the high boundary lyr convective inhibition
we're expecting over nrn WA. This is true also for the Camas
Prairie of Idaho near Lewiston early evening, but to a much lesser
extent. This is our best chance though for thunder this evening.

12z tafs: an upper level warm front will keep high clouds over the
region this morning, then a mid level cold front will slide across
the taf sites by afternoon. Expect west to southwest winds to
increase late this afternoon and early evening with local gusts to
25 mph. Clouds and winds will decrease overnight. /Rfox.
