9:15 PM Update:
- High Wind Warning and Lake Wind Advisory have been allowed to
  expire, wind speeds and gusts have lowered and no longer meet
  warning thresholds.
KEY MESSAGES:
- Below normal temperatures are expected into Saturday with some
places possibly experiencing a freeze Saturday morning.
- A warm-up is expected starting this weekend.
WEATHER PATTERN OVERVIEW:
Cooler air has been filtering into the CWA today behind a cold
frontal passage this morning. Stacked low over southern Manitoba
will allow for a cloud shield to move south into ND tonight
keeping areas along the ND border slower to clear out with
diminishing wind, which is expected over the western zones. Many
areas tonight will drop into the 30s but a widespread freeze is
not expected.
Friday should feature a much quieter day with lighter winds and
sunshine.
An upper ridge over the Pacific NW is expected to flatten while it
drifts into Montana by early next week. This will allow for mainly
clear skies and temps rebounding into the 80s.
Then an upper low will push into the Pacific NW that splits with a
piece looking to break off into the Canadian Prairies. This set-up
may give the area the chance of thunderstorms Wednesday as some
moisture and instability from the Dakotas moves into the area.
FORECAST CONFIDENCE & DEVIATIONS:
Mainly stayed with NBM but blended the NBM90 into the winds
through Friday and blended NBM25 for low temperatures tonight and
Friday night. TFJ/RDJ
