A trough axis currently across southern Saskatchewan will swing
south through eastern Montana this evening into tonight. We are
seeing clouds across far eastern Montana this afternoon associated
with the lift and limited moisture ahead of the trough.

Nothing notable in the way of moisture will move into Montana
tonight associated with this trough, so widespread development of
mid-high clouds is not expected. There could, however, be moisture
trapped underneath the inversion tonight into Tuesday, which
could lead to development of low clouds and perhaps some fog once
again - though the fog should not be as widespread as what we have
seen the past few days.

Dry weather with warming temperatures is then expected through the
remainder of the week with an upper-level high over the area.
Expect continued snow melt through the week with the amount of
melting increasing as many areas rise into the 50s for the middle
and latter part of the week. Low temperatures are still expected
to fall below freezing each night.

As far as the potential weekend system goes, the trend over the
past month has been for these to remain south of the region and
this is indeed the trend the models are hooking onto. Cannot rule
out some isolated rain/snow showers over the weekend, but it is
looking like impacts will be minimal.



Expected Flight Category: VFR-IFR

Synopsis: Mostly VFR conditions through the forecast period with a
chance for fog and/or low clouds to bring IFR conditions to TAF
sites late tonight into Tuesday morning.

Winds: Around 5 kts out of the northwest tonight becoming west at
10 to 15 knots Tuesday.
