.SYNOPSIS...
Temperatures will trend much warmer beginning Sunday, and
continue through the middle of next week. Temperatures will
cool slightly for the middle to end of next week but will remain
above normal.

&&

.DISCUSSION...
Tonight through Tuesday: The ridge of high pressure continues
to build through Tuesday, with warming temperatures and drying
conditions. Temperatures will warm into the 90s by Monday, with
upper 90s and low 100s by Tuesday. A Heat Advisory remains in
effect for much of the lower elevations with the exception of
the Cascades and Kellogg/Lookout Pass area. The Heat Advisory is
active from 9 AM Monday through 9 PM Tuesday. These will be the
warmest temperatures of the year so far, with a few locations
reaching near record, but are not forecasted to break any. Make
sure to take care in the heat by drinking plenty of fluids,
staying in an air- conditioned room, staying out of the sun, and
check up on relatives and neighbors.

Wednesday through Friday: Ensembles are coming into better
agreement that a shortwave will pass to the north, allowing for
the ridge to flatten. Even with the flattening ridge,
temperatures will remain above normal, mainly in the 80s to low
90s. Cascade gap winds also are a concern for Wednesday and
Thursday due to the pattern changing, especially after the warm
and dry conditions earlier in the week. Westerly winds will
increase in the Columbia Basin and stretching out towards
Spokane and the LC Valley, with gusts Wednesday and Thursday
afternoons gusting to 25 to 35 mph. With those gusts, continued
above normal temperatures and humidity dropping into the teens,
we will monitor these days as they are trending towards elevated
fire weather concerns. By Thursday and the Fourth of July,
ensembles are in agreement of a return to a warm and dry
forecast. Make sure to take precautions in the heat. /KK
