Area Forecast Discussion
National Weather Service Boise ID
407 AM MDT Fri Jun 7 2024

.SHORT TERM...Today through Sunday night...Most areas will see
less cloud cover today as a W-NW flow brings in drier air at
mid-levels. The exception will be areas along the OR/NV and
ID/NV border where lingering moisture will support scattered
showers and thunderstorms. While activity is expected to stay
out of the Snake Plain, the western Magic Valley could
experience outflow winds from cells to the south. Gust potential
near the heavier showers and thunderstorms is up to 45 mph.
Saturday is mostly dry across the region as an upper ridge axis
moves overhead. A few late afternoon showers/storms could build
over higher terrain south of Twin Falls and across far western
Harney County. The chance for showers and thunderstorms
increases Saturday night into Sunday as an upper trough pushes
into the Pac NW. Higher terrain will see the best chance of
precipitation (40-60%) Sunday afternoon/evening. Brief heavy
rain and gusty winds could accompany heavier showers and
thunderstorms. Temperatures will be well above average through
Saturday. Sunday is not as hot but will still see highs around
10 degrees above normal.

.LONG TERM...Monday through Friday...Next week will see stretch
of dry and warm weather as a low amplitude ridge sets up over
the region. The west-southwest flow will keep temperatures
around 10 degrees above normal, putting lower elevation highs
near 90F each day. Any chance of precipitation would come late
Thur/Fri with a low tracking through the southern Great Basin,
but confidence in this feature are low at this time.

.AVIATION...VFR with another round of afternoon showers and
isolated thunderstorms. Development will be mostly along the
northern NV border between 19Z and Sat/03Z. Activity extending
into SE Oregon to near the KBNO terminal between Sat/00Z-06Z.
Gusty and erratic outflow winds to 40 kt possible from storms.
Surface winds: 5-15 kt, except gusty near storms. Winds at 10k
ft MSL: SW- NW 10-20 kt.

KBOI...VFR with light NW winds developing today.

Weekend Outlook...VFR. Isolated to scattered showers and
thunderstorms Saturday evening across SE Oregon spreading to all
areas Sunday. Heavier showers and thunderstorms will produce
brief MVFR conditions with brief heavy rain and gusty winds
possible. Highest confidence of convection is Sunday. Otherwise,
surface winds generally W-NW 5-15 kt.
