Area Forecast Discussion
National Weather Service Boise ID
858 PM MDT Sun Jul 28 2024

.DISCUSSION...A weak upper disturbance in eastern Oregon will
move through our northern areas overnight, accompanied by
clouds but no rainfall. Otherwise, dry conditions prevail
through Monday as an upper trough off the coast enters the
Pacific Northwest. Temperatures are expected to be similar to
today with highs slightly below normal. Smoke from wildfires
will continue across the region. No updates.

&&

.AVIATION...Areas of MVFR and local IFR in smoke. Surface
winds: W- NW 5-15 kts across SE Oregon overnight and variable
less than 10 kts elsewhere. Winds aloft at 10kft MSL: W-SW 10-20
kt.

KBOI...Low-VFR at times in smoke. Light diurnal surface winds,
SE overnight and NW during the day.

.PREV DISCUSSION...
SHORT TERM...Tonight through Tuesday night...Smoke from wild
fires will continue over the area through Monday.
However...winds are starting to shift to a more westerly
direction and smoke is expected to thin out a bit on Monday and
Tuesday. The change in wind direction will shift smoke from the
Park Fire in California so that it will stay south of the
Nevada border. A weak cold front will approach the area on
Monday night and move through the area on Tuesday which should
also help clear the air. Still...areas immediately down wind
from local wild fires will still be affected by smoky
conditions. The front will bring scattered rain showers to the
northern half of the forecast area Monday night and Tuesday but
total precipitation will be less than a tenth of an inch.

LONG TERM...Wednesday through Sunday...The upper level ridge
will re-intensify over the area beginning on Wednesday and the
heat wave will return with temperatures reaching the triple
digits again in lower valley locations by Thursday afternoon.
Very hot weather will continue through Sunday with no
precipitation expected.
