Area Forecast Discussion
National Weather Service Boise ID
838 PM MDT WED SEP 21 2016

.DISCUSSION...WSR-88D radar showed showers and isolated
thunderstorms this evening in eastern Oregon and southwestern
Idaho generally moving toward the north-northeast. Some of these
showers were producing brief moderate rain in the Boise and West
Central Mountains of Idaho with rainfall rates of 0.10 to 0.20
inches per hour. The current thinking is that these rainfall rates
are probably not heavy enough to cause significant runoff on
recent burn scars. However, the NWS is carefully monitoring rain
amounts in the vicinity of the Pioneer burn area in case the
showers unexpectedly intensify. Satellite derived water vapor
imagery still indicates that a dry slot will move into the area
after midnight and shower activity is expected to diminish until
moisture wraps back around the northwest side of the upper low
into the area again tomorrow afternoon.

&&

AVIATION...Widespread showers with local MVFR and brief IFR
conditions will continue through Thursday over the west-central
Idaho and Boise Mountains and areas east and south of KMUO. Showers
will be scattered in the Snake River Valley and adjacent highlands
west of KMUO, and in eastern Oregon overnight, but become more
numerous on Thursday west of a KREO-KMYL line. Expect areas of
mountain obscuration. Isolated thunderstorms are possible in eastern
Oregon Thursday afternoon. Surface winds will be variable in
direction 10-15 kts, becoming northwest 10-20 kts Thursday
afternoon. Winds aloft at 10k ft msl southwest 20-30 kts.

&&

.PREV DISCUSSION...
SHORT TERM...Tonight through Friday...Unsettled weather is in
store for the next couple of days as an upper level low near the
Oregon coast moves inland and over northern Nevada Thursday.
Moisture and lift ahead of the system will spread showers across the
area with the eastern portion of the forecast area still the focus
for highest rainfall amounts. A surge of drier air will limit
showers tonight across far southeast Oregon and southwest Idaho
near the Oregon border. As the low moves east across northern
Nevada Thursday and Thursday night, moisture will wrap around the
north side of the low and bring a better chance of precipitation
to the Oregon side as well as the Lower Treasure Valley.
Precipitation chances will gradually taper off from west to east
Friday but strong northwesterly flow on the back side of the
system will bring windy conditions to the region. Strongest winds
on Friday will be across the Western Magic and Upper Treasure
Valley, and areas south to the Nevada border.

Rainfall totals through Friday afternoon will be in the 1.0 to
1.5 inch range for much of the Western Magic Valley and southern
Twin Falls County, with amounts from .50 to 1.25 inches across
eastern portions of the West Central Mountains and Boise
Mountains. Will need to monitor recent burned areas for
development of intense rainfall and flash flood potential. Daytime
highs will be 10 to 15 degrees below normal Thursday and Friday
with snow levels lowering to around 8000 feet.

LONG TERM...Friday night through Wednesday. Upper level trough will
exit the region Friday night and moist northwest flow will continue
through Saturday afternoon, keeping a chance of showers over the
higher terrain north of Baker City and McCall. Drier air moves into
the region as upper level ridging builds into the region on Sunday.
Expect mostly sunny skies, but northerly flow will keep temperatures
from warming to their maximum potential. Temperatures by Tuesday
warm to around 4 to 8 degrees above normal before the ridge dampens
on Wednesday and temperatures return to normal values for this time
of year.
