Area Forecast Discussion...Updated
National Weather Service Billings MT
933 AM MDT Sat Jun 17 2017

Disturbance sliding southeastward across northeast Montana
supporting scattered shower activity in southeast Montana with a
drying trend across western portions of the area. Breezy
conditions kicking in which will make it seem cool despite strong
sunshine kicking in. Updated forecast to adjust areas of
precipitation and increase winds a bit. borsum


.SHORT TERM...valid for Tdy and Sun...

There continues to be some lift connected with some jet
divergence over the area. This will continue to move south and
east this morning as ridging moves in from the west. The light to
moderate rainfall will continue move out with the divergence.
Some lingering energy across the east will keep the showers going
through the afternoon. Some gusty winds will work down this
morning which will produce gusts 35 to 40 mph across much of the
area. Winds will decrease overnight as the jet finally pushes out
of the area. Sunday looks to be dry and warm across the area.

.LONG TERM...valid for Mon...Tue...Wed...Thu...Fri...

No major changes in the overnight models, and latest forecast is
minimally changed from previous. Heights are on the rise Monday
into Tuesday as 588dm ridge builds into the area from the west.
Temperatures push into the 80s for Monday with dry conditions,
then the lower 90s for Tuesday ahead of a late day cold front.
Expect isolated to scattered showers/tstms Tuesday afternoon into
the evening along the front and in the higher terrain.
Temperatures trend lower Wednesday into Friday as heights aloft
fall and Northwesterly jet stream drops over the area. This extra
energy aloft and cyclonic flow overhead should be enough for at
least isolated showers and thunderstorms for the higher terrain
and adjacent plains, and may end up a bit more widespread than
currently advertised. Did increase precipitation chances for this
period, especially in the afternoon/evening hours. Another
Canadian front drops into the area late Friday into Saturday with
additional chances for precipitation, and holds temperatures near
to below seasonal levels for the weekend. Overall not a bad mid
June forecast with no big impacts, but drier than normal
conditions for this time of year with the Gulf of Mexico moisture
remaining largely absent. Chambers



VFR conditions will prevail across the area today. Areas of
showers and VFR ceilings will exit the area to the east with
gusty west to northwest winds filling in behind the exiting
precipitation. Expect wind gusts of 25 to 35 kts today in most
locations, diminishing after 00z. Chambers/borsum
