Short term...today through Monday...a quiet forecast is in store
for the short term forecast period going into the extended forecast.
Though the pattern does not show a strong upper ridge the thickness
and height values increase, suggesting very warm to hot conditions
with the warming trend starting today and continuing throughout the
forecast period. Temperatures are expected to be about a couple
degrees warmer today than on Friday...and then more significant
warming is forecast to take place Sunday and Monday. Today highs are
expected to be in the upper 70s to mid 80s...except upper 60s to mid
70s mountains. Maximum temperatures are expected to rise to the
upper 80s to lower 90s on Sunday in the lower elevations...and then
in the 90s lower elevations on Monday. Temperatures will keep rising
going into the extended period. The County Warning Area is going to be precipitation
free through the short term with quiet conditions. Winds will
generally be light but it may become breezy to windy at times in the
eastern Columbia Gorge...the lower lower Columbia Basin and along
the Cascade east slopes (mainly the Kittitas valley) at times...but
nothing to strong. 88

Long term...Monday night through Saturday...a quiet weather pattern
is in store through next week. A weak trough of low pressure will
move across the region Monday evening but as of now it looks a bit
too dry to trigger any showers or thunderstorms. Afterwords a ridge
of high pressure will be the dominant weather feature through
Saturday. It will become increasingly warm with highs well into the
90s lower elevations Wednesday and Thursday. By Friday and Saturday
it will become quite hot with afternoon highs in the Columbia Basin
and adjacent valleys in the low 100s to around 105 degrees. Went
higher than the guidance temperatures (which were around 100
degrees) given the the low level temperatures in the raw model
output that support temperatures of 105-110 degrees. 78

Aviation...12z tafs...VFR conditions are expected for the next 24
hours. Just a few high level clouds are expected today otherwise
mostly clear skies will prevail. Winds will be mostly 10 knots or less
except for west at 15-25 knots at kdls this afternoon. 78
