.DISCUSSION...

KEY MESSAGES:

- Temperature continues to swing with an unsettled weather
  pattern over the next week.

- Another weak system moves through tonight bringing an inch or
  less of snow. Several systems with mixed precipitation are
  expected Monday night and beyond with low confidence in
  precipitation type at this time.

WEATHER PATTERN OVERVIEW:

A northwest upper flow regime will continue across the area
through the next week with systems bringing a fluxuations of
temperatures, precipitation and winds.

The next one due to move east across the area will be tonight with
generally an inch or less of snow. This feature is a warm front,
so temperatures Sunday should be a bit warmer than today (and
lighter winds with afternoon sunshine should help feel not as cold).

A strong clipper will then drop southeast across the northeast
zones early Tuesday. Overrunning ahead of the system will bring
rain, snow and likely some freezing rain. Highlights may be needed
as the ground could be colder than freezing with any rainfall.
Then a cold front drops in late morning/early afternoon Tuesday
that will drop temperatures and possibly bring snowshowers during
the afternoon.

Winds will also increase Monday night into Tuesday that could be
strong enough for a High Wind Watch. Winds look strongest in
southwest Phillips county at this time.

Temperatures will then be on the downward slide into Friday, where
highs Friday may not reach zero in the northeast zones. Extreme
Cold highlights look likely at this point. Some light snow is also
possible.

FORECAST CONFIDENCE & DEVIATIONS:

Basically followed the NBM for all elements, but increased them
for winds Tuesday and Tuesday evening.

Confidence in increasing in warmer temperatures Sunday into
Tuesday morning. TFJ
