.DISCUSSION...
Synopsis:
A couple cut-off lows exist over the region. The one just to our
north is expected to drift east into Manitoba today. The other low
is dropping SW from British Columbia and is expected to remain
off the Pac NW coast for the next few days.

Skies have cleared early this morning with high humidity that has
allowed some fog to form briefly. The big question this morning is
will the fog become widespread and dense before the sun burns it
off by afternoon. The NBM favors it to form over the lower Milk
and Missouri River valleys but HREF is showing less confidence for
fog. With the low confidence, will hold off on any headlines for
this.

With the upper low over BC, the zonal flow today and Thursday
will become more meridional as a ridge over the Eastern Montana is
induced. This won`t boost temps much but will send moisture in on
Friday in the form of clouds.

Precip chances do increase over the weekend with the highest
chances for rain coming Sunday night.

Clearing is expected behind the system early next week with an
upper ridge bringing in drier conditions.

FORECAST CONFIDENCE & DEVIATIONS:
There were no deviations from the NBM, but confidence on its
handling of the fog is low. The HREF is showing low confidence on
the fog so widespread dense fog is not expected at this time. TFJ
