Area Forecast Discussion
National Weather Service GLASGOW MT

.SHORT TERM...for northeast Montana...today through Sat...
Update...

The inherited forecast remains in excellent working order. Expect
mainly cool and dry conditions today with showers entering in from
the west later tonight as the main trough axis passes right over
eastern Montana. Maliawco

Previous Discussion...

Repeated upper-level troughs that emerge from the northern and
Canadian Rockies will keep the relatively cooler air mass in place
over northeast Montana over the next few days. After another cool
start to the day today, temperatures are expected to gradually
moderate back toward seasonable averages into the weekend.

The next most prominent trough passage expected to bring some
precipitation to the area will be on Friday. Expect scattered rain
showers with a few thunderstorms possible from WNW to ESE early
Friday morning through late Friday night. Overall model agreement
is pretty good, but the model differences in the placement of the
precipitation suggests that the rain showers will be spotty and
scattered in nature. Some more accumulating wetting rain may be
possible north of the Missouri River. BMickelson



.LONG TERM...Sat night through Thu...

Look for zonal flow aloft Sunday and Monday. Shortwave troughs
will move across Saskatchewan on both days. Expect a dry cold
front on Sunday. Monday`s wave could bring a slight chance of
showers and thunderstorms Monday afternoon and night.

Flow aloft turns to the southwest on Tuesday as an upper trough
digs south along the Pacific Coast. Expect the SW flow to continue
the remainder of the period. Waves in the SW flow aloft could
bring a chance of showers Tuesday, Wednesday, and Thursday to the
forecast area. Forrester
