.SHORT TERM...today through Sunday morning...Satellite shows
stratus entering from the WA Cascade and into the region. With a
shortwave passing through the PacNW, chances of PoP across the WA
Cascades increase through the afternoon and early evening hours.
Precip may extend close to the Yakima/Ellensburg area during the
late afternoon/early evening (>80% chance). Nothing to suggest
any thunder will be associated with these storms. Weather will
clear by the early morning hours of Friday with a ridge starting
to push through the area. Temperatures will slow rise through the
short term as the pattern begins to favor a warming trend from the
short term that will last through the long term. Winds will be
breezy across the Basin with general diurnal winds through the
next few days. Strongest winds will be today through Friday, with
most places capping their gusts at 20-30 knots.


.LONG TERM...Sunday morning through Thursday...The long term is
more animated than the short term, with a ridge setting up for a
potential heat wave during the holiday week coupled with
potential of thunderstorms in Central OR.

Ridging will start moving through the region over the weekend,
setting up a pattern for temperatures to begin a warming trend
over the weekend. High temperatures will tapper off in the mid 90s
for much of the Basin plus Central OR/Kittitas Valleys. Monday
appears to be the hottest day with NBM delivering triple digits
for the Columbia Basin and creeping into the Kittitas. NBM
currently advertises 40-60% chances of temperatures exceeding 100
degrees in the Tri-Cities area, among other portions of the WA
Columbia Basin. Heat advisories might need to be considered for
the Columbia Basin/Gorge as preliminary Heat Risk values are >3
for the Mon-Tues timeframe. Any advisories needed or added will be
assessed and decided through the next few days if they are still
warranted.

A break in the ridge with a shortwave will push down through the
region Monday, allowing for some moisture advection (coupled with
the daytime heating) to bring chances of thunderstorms across
Central OR and across large parts of the Blues. The highest chance
for thunderstorm development will be the early afternoon through
evening hours of Monday. Chances decrease vastly as we head into
Tuesday, with remnant showers lingering across the southern part
of the region. Things become a bit less confident heading into
Wednesday, as things naturally become less clear this far out.
Members are completely split Tuesday going into Wednesday onwards
how strong it will make the trough behind the ridge. Looking at
meteograms confirms that temperatures wildly fluctuate around
this same time frame.
