.DISCUSSION...

WEATHER PATTERN OVERVIEW:

Today`s flow pattern is becoming post-frontal from the northwest
with some chinook warming. For Saturday and Sunday, a tight
pressure gradient will set up over the area to bring much above
normal temperatures. There greatest (>50%) chance of gusts
reaching 50 mph is over Phillips and Petroleum counties on
Sunday. The 50th percentile for max wind gusts on Sunday for SW
Phillips county is around 60 mph, where a High Wind Watch remains
in effect. There will likely be patchy blowing dust Sunday in
open areas of western Phillips county that have not received
moisture lately and have gusts over 45 mph.

On Sunday evening, an upper trough in Canada is expected to push
southward with a cold front and remain over the area during most
of the week to bring chances for mixed precipitation. At present
the snow amounts Sunday evening do not look high enough for
blowing snow concerns, but cannot rule out snow squall impacts as
temperatures fall rapidly. Most ensemble members show highs in
the 30s and 40s next week with this pattern, which is seasonable
for mid March.

FORECAST CONFIDENCE & DEVIATIONS:

No notable deviations were made.

There is moderate to high confidence in temperatures over the next
few days, dependent on strength of chinook and associated cloud
cover. There is moderate to high confidence of a High Wind
Warning being issued for Sunday over the Little Rockies, with low
confidence elsewhere.
