.SHORT TERM...valid for Sat and Sun...

Northwest flow aloft pushing drier air into the region but cold
temperatures under a sharp upper level trough combining with
moist ground to produce small isolated showers. Expect this
activity to dissipate after sunset and a dry weekend is in store
for the region. Temperatures on Saturday will rebound as leeside
troughing promotes better mixing but some residual moisture may
cut a degree or two off of maxes due to evaporative cooling.

By Sunday an upper level ridge moves into the area and begins
breaking down with stronger leeside troughing. This combination
brings even warmer temperatures about 5 degrees above normal. The
downslope is maintained Sunday night for low temperatures back to
near 60. borsum

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

Models have slowed the timing on the front moving through on
Monday a little with the latest runs. The timing is now more of
an overnight passage. That being said, models are still not
showing much in the line of moisture with this system, so have
maintained PoPs pretty much as is. Through the remainder of the
week, the area will remain in northwest flow. Towards the end of
the week, a weak low pressure system drops into the Pacific
Northwest, which while not moving into Montana, some energy from
this system will move through the flow giving a bit better chance
at some rainfall.

Tempeatures through most of the period will be more more seasonal
and even a little below normal. Monday will be warmer ahead of
the front moving through during the night. With downsloping,
temperatures climb into the 90s. Through the rest of the week
expect temperatures with the northwest flow to be mainly in the
70s. Reimer


Scattered afternoon light showers will diminish this evening.
Expect VFR conditions to continue, though localized MVFR
conditions possible with a stronger shower. Reimer
