Area Forecast Discussion...Updated
National Weather Service Billings MT
849 PM MST Sun Feb 12 2017

Only some minor cosmetic adjustments for this evening. Forecast
looks to be in good shape. BT


.SHORT TERM...valid for Mon and Tue...

Blocking pattern across the western CONUS will result in ridging
over the northern Rockies and high plains, and quiet weather in
our cwa through the short term period. Temperatures will turn
gradually warmer. Expect widespread 40s tomorrow and and mid 40s
to mid 50s Tuesday, as persistent downslope flow pushes 850mb
temps to +8C to +10C. Winds will be gusty at times along the
western foothills, but mid level flow will not be as strong as
today so do not anticipate any wind problems. Dry conditions will
prevail as heights rise gradually to near 570dam.

High water issues resulting from ice jams continue along the
Musselshell River from near Roundup and downriver to the east.
Have extended the flood advisory for this area til tomorrow.


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

Temperatures continue to rise as we head into mid-week as ridging
builds in from the west. Guidance continues to show mid to upper
50s possible on Wednesday and Thursday which should mark the end
to the snow pack across the low country. A lee trough will form
and increase winds over the west beginning Tuesday night and
continue into early Thursday. These winds would impact the
Livingston to Big Timber and northward to Harlowton areas the
most. Moisture begins to push into the region Thursday night and
Friday bringing a slight chance of rain/snow mix across most of
the region. Pattern remains unsettled but still warmer than normal
through the weekend. Walsh



VFR conditions will prevail through tomorrow afternoon. Winds
will gust this afternoon at BIL and LVM before relaxing by
evening. Gusts 20-30 kts possible at BIL, with 30-40 kt gusts
possible at LVM. Walsh
