.SHORT TERM...for northeast Montana...tonight through Sat...
An upper trough over the region will continue to influence the
weather conditions through tonight and Friday with increasing
clouds and eventually scattered showers moving in from the west.
In general, rainfall amounts will be fairly light though some
places could see a few hundredths of an inch.
Do expect that drier and warmer conditions will prevail into
Saturday as high pressure moves in along with rising heights. A
return to daytime highs in the 80s is forecast with a few
locations nearest the Canadian border in the upper 70s. Maliawco

.LONG TERM...Sat night through Thu...
The forecast was in good shape and only minor changes were made.
The main changes were mainly to bump up precipitation chances
just a little to account for the possibility of an isolated
thunderstorm to impact our western areas Monday night. Models are
still somewhat uncertain regarding the timing of the waves in the
SW flow that are expected to move through the area next week, so
decided to leave slight chances for showers for much of the middle
of next week. There may also be enough surface heating in the
afternoon, so decided to leave in a slight chance of thunderstorms
for the afternoon and evening hours for much of next week.

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


VFR conditions are expected.  A cold front will bring a
chance of showers to the area terminals late tonight into Friday
with ceilings potentially lowering to 5000 ft. Winds will become
light and variable after dark. Maliawco
