.DISCUSSION...No updates for today`s forecast. Temperatures will
run about 5 degrees warmer than yesterday under full sun. A weaker
surface pressure gradient and winds aloft will make for lighter
surface winds this afternoon. Heat is still on track for later in
the week, with near record heat during the weekend.


.AVIATION...VFR with just a few high clouds. Surface winds: light
northwest up to 10 kts. Winds aloft to 10K feet MSL: north to
northwest 10-15 kts.


SHORT TERM...Today through Wednesday...Temperatures will be
warmer today and Wednesday as a strong upper ridge along the west
coast slides into our area. The highest temperatures will be
around 80F today and near 90F Wednesday, including the Treasure
Valley. The dry weather will continue, except a weak disturbance
will move across the far north on Wednesday for a slight chance of
late afternoon and evening thunderstorms (north of Baker City and

LONG TERM...Wednesday night through Tuesday...Weak system moving
through Western Canada on Thursday suppresses the upper-level
ridge somewhat, keeping temperatures stalled at merely 10-15
degrees above normal through Friday. Then southerly flow increases
for Saturday and Sunday as a cut-off low approaches California,
and temperatures reach 20 degrees above normal, with highs in many
lower valleys approaching 100F. Moisture also increases from the
south, with reasonable chances for showers and thunderstorms
Sunday afternoon, but better chances on Monday and Tuesday. Timing
of cut-off low lifting up and over the area for Monday and/or
Tuesday is still pretty uncertain among models, but clouds and
showers should eventually bring temperatures back to just hot,
rather than ridiculous.
