KEY MESSAGES

- Possible fog tonight into tomorrow morning.

- Dry conditions are expected over the next several days but chances for rainfall are expected this weekend.

- Temperatures will remain close or slightly above normal.

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.

There is a decent chance of fog occurring tonight into the morning tomorrow, but it is not guaranteed to happen.

With the upper low over BC, the zonal flow today and tomorrow 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. THere is uncertainty of how much precipitation will fall.

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

FORECAST CONFIDENCE & DEVIATIONS: No deviations from the NBM.

There is moderate to high confidence in temperatures this week, and moderate confidence in fog occurring tonight and lasting through mid morning tomorrow.

There is low confidence in precipitation type and amounts this weekend.
