Area Forecast Discussion
National Weather Service Billings MT
836 PM MDT MON AUG 1 2016

.UPDATE...

Current visible satellite imagery shows a substantial smoke plume
from central Idaho, as well as fires near Missoula and Jackson.
Generally westerly flow around 700 mb will push patchy smoke into
the western foothills and mountains overnight. Tomorrow, winds
increase out of the southeast ahead of a developing lee side
trough. These winds look to be a bit stronger than previously
forecast so wind speed was increased over the Plains tomorrow
afternoon to around 20 mph out of the southeast. Other than those
changes the forecast remains largely unchanged for tonight. High
pressure will remain in place over the area, with clear skies and
temperatures ranging from the mid 50s to near 60. Walsh

&&

.SHORT TERM...valid for Tue and Wed...

Quiet weather is in store for tonight with upper ridging and
a dry airmass in place. The ridge shifts E during Tue. and SW flow
with a few shortwaves moves into the western zones in the
afternoon. Bufkit soundings showed high-level moisture and
inverted-v profiles W of KBIL. Kept the slight chance of thunder
for areas W of KBIL and expanded it a bit further E. These storms
will likely be mostly dry with gusty winds. Precipitable waters
increase to an inch over the far eastern zones Tue. afternoon due
to a SE low-level jet that strengthens with time. Bufkit soundings
showed increasing shear and CAPES in the evening and SPC had a
Marginal Risk for the E. So, held off the severe wording until the
evening in the E.

The upper low seen on water vapor imagery off the S BC coast this
afternoon, moves into NW MT by 12Z Wed. Diffluence precedes the
low and the system's cold front moves through W MT by 06Z
Wednesday. The front was forecast to move through KBIL before 12Z,
then through the rest of the area by 18Z. Bufkit WRF/GFS showed
winds in the 20s and 30s in the column behind the front which will
create windy conditions on Wed. across the N half of the area.
Airmass quickly dries out behind the front, so just had PoPs in
the E on Wednesday. Kept Wed. night dry behind the front.

The threat of dry thunderstorms will be over the W and NE Bighorns
on Tue., along with low humidities and temperatures in the 90s. On
Wed., the frontal passage, gusty NW winds and low humidities will
create hazardous fire weather conditions. Thus will issue a Fire
Weather Watch for the above conditions. Arthur

.LONG TERM...valid for Thu...Fri...Sat...Sun...Mon...

Surface high pressure to the east of a 500 mb shortwave ridge
axis should dominate the weather on Thursday with clear skies,
calm winds, and relatively cool air with high temperatures in the
80s.

On Friday, upper ridge axis begins to push eastward a bit,
allowing for a more southerly flow to dominate the region. This
flow should allow high temperatures to rise a few degrees from
Thursday's readings. Could see a few thunderstorms develop over
southwestern/far southern zones as southwesterly flow aloft kicks
in behind ridge axis.

Southwesterly flow pattern continues for Saturday through Monday,
with scattered thunderstorms possible across south central and
southeastern Montana and north central Wyoming. High temperatures
should generally be in the 80s to lower 90s Sat-Mon.

Potential is there for breezy conditions over southeastern
Montana on Saturday as surface pressure gradient tightens between
a surface trough east of the mountains and surface high pressure
over the north central Plains. These winds should be
southeasterly...and thus transport moist air to SE MT...keeping
dewpoints and relative humidities high enough to avoid fire
weather problems. RMS/Arthur
&&

.AVIATION...

VFR conditions will prevail tonight. Southeast winds just above
the surface will increase from Billings east into the Dakotas and
may result in some areas of low level wind shear from midnight
through 9 am. Chambers
