.SHORT TERM...Tonight through Wednesday night. Satellite imagery
shows strong shortwave dropping out of BC Canada with circulation
center just north of Idaho panhandle. Strong drying ahead of
shortwave pushing through PacNW states with deepest moisture left
over Montana. Winds beginning to increase across East Idaho this
afternoon as gradient tightens. Moisture band associated with
initial front system is very thin so have left only weak
collaborative chances for precip along northern and southern
borders where best chances exist. In the meantime will leave wind
headlines in place as strongest winds likely between 21z-03z.
Gradient weakens slightly and turns northeast overnight except
over central mtns and along Divide. Base of shortwave trough dives
south into northern California/Nevada and cuts off during the day
Monday. Southwest flow continues across East Idaho with moisture
becoming more widespread. Have increased precip chances across the
region Monday into Monday night as low tightens and rotates more
consolidated band north into the forecast area. Moisture wraps
closer to the low centered over northern Nevada during the day
Tuesday with both GFS and NAM pushing dry wedge north into the
region. As the low begins to eject northeast Tuesday night, the
moisture clustered around the low spreads across the region. Low
center shifts across East Idaho Wednesday with trough axis east of
the region by Thursday morning. Precipitation Wednesday begins to
shift east of the region with most of the region drying out
completely Wednesday night. DMH

.LONG TERM...Thursday through Sunday. Have left a few lingering
showers along Wyoming border during the day Thursday but otherwise
dry pattern setting in for remainder of the forecast. Upper ridge
amplifies across the Great Basin and East Idaho Thursday night
through Saturday. Pacific shortwaves try to flatten the ridge into
the weekend but both GFS and ECMWF keep energy well north along
the Canadian border. Dry and warm (near or slightly above normal)
temperatures are forecast through the remainder of the forecast
period. DMH

.AVIATION...A strong cold front is moving through the area this
afternoon. Expect gusty winds for all TAF sites this afternoon into
early evening. Also...expect low-level wind shear this afternoon for
KSUN. Cigs are expected to remain VFR but become cloudy....mostly
mid-level...by early morning. Wyatt

&&

.FIRE WEATHER...A strong cold front is moving through area this
afternoon. Expect gusts of 25 to 35 mph across much of the area this
afternoon into early evening. Higher gusts are possible over the
Arco desert and INL. Temperatures will be warmer this afternoon with
afternoon humidity readings ranging from the upper single digits to
the mid teens. A red flag is in effect this afternoon until 9 pm mdt
for all zones expect 475 where relative humidities are slightly
higher.

Monday expect breezy Northerly winds with low relative humidity in
the twenties to thirties and temperatures dropping significantly
behind an exiting cold front. Only a slight chance of thunderstorms
is expected over the Central mountains and Eastern Highlands
mountains on Monday. The upper trough deepens into a upper level low
over Northern California by Tuesday morning. Models continue to move
this low over our area late Tuesday into Wednesday. Look for
isolated mountain showers and thunderstorms on Tuesday with more
widespread showers and isolated thunderstorms on Wednesday. Wyatt
