.DISCUSSION...

Breezy and cooler conditions this afternoon will linger until
sunset. Expect temperatures overnight to be cooler than the past
couple of weeks. Mild and sunny conditions over the weekend with
the models showing a rebound in temperatures for Sunday and
Monday. A weak monsoon push combined with another cold front
sweeping through the area late Monday into Tuesday will produce
the potential for thunderstorms along the Idaho Utah border.
Expect breezy conditions on Wednesday and cooler. Southwest flow
enhances again at the end of next week with possible
thunderstorms by next Friday. preston

.AVIATION...Expect breezy to moderate Northeast winds to continue
for KIDA and KPIH and to a lesser extent for KBYI this afternoon as
a dry cold front moves through the area. Look for clear skies and
overall light winds tomorrow as high pressure builds back into the
area. Wyatt

.FIRE WEATHER...Breezy to moderate Northeast winds are still
occurring behind a dry cold front that moved through this morning.
Relative humidity is currently around 25 to 35 percent and will drop
around 5 to 10 percent more. However...winds are starting to drop
slightly as the afternoon progresses. Temperatures are several
degrees below normal today behind the cold front. Temperatures will
rebound Saturday to near normal and Sunday above normal as high
pressure ridging builds back into the area. Monday look for winds
from the Southwest to start to increase ahead of the next system
that will graze our Northern areas late Monday. Models are now
showing the possibility of afternoon thunderstorms across our
Southern borders on Monday. Monday a red flag warning may be needed
for our Southern areas for lightning and our Northern areas for
gusty winds and low relative humidity.  Wyatt
