.DISCUSSION...Warm and dry today under westerly flow aloft. Winds
will be light with temperatures similar to yesterday. Moisture
has left the region so thunderstorms are not expected. Satellite
showing active fires from yesterday's lightning mainly in Owyhee
county this morning. Smoke from these fires should remain south of
the Treasure Valley. Southern Twin Falls County could see some
smoke layers later this afternoon and evening. Forecast remains on
track so no updates needed at this time.
.AVIATION...VFR with clear skies. SFC winds will be light and
variable at less than 10 kts, except in the snake river plain west
of KBOI-KMUO were winds will be west or northwest at 10 to 15 kts
this afternoon. Winds aloft to 10k feet MSl, west-southwest 15-20kts.
SHORT TERM...Today through Wednesday...Any lingering shower
activity will taper off this morning. Building westerly flow will
keep the area out of monsoonal moisture for the next couple of
days, with dry conditions expected. Models do show and increased
pressure gradient across the area by Wednesday morning, which may
result in gusty wind. Otherwise, expect warm temperatures through
Wednesday with values generally 5 to 10 degrees above normal.
LONG TERM...Wednesday night through Monday...Hot and dry
conditions continue to dominate the forecast. Models are still
suggesting some return of monsoonal moisture by the start of the
weekend into early next week, but looks to remain in our extreme
southern zones close to the Nevada border. Temperatures remain above
normal through Saturday then dip down a few degrees to sit right
around climatological norms.
