.DISCUSSION...

KEY MESSAGES:

- Gusty west winds through Wednesday evening.

- Dry and warmer weather through the end of the week.

WEATHER PATTERN OVERVIEW:

A low pressure system moving across central Saskatchewan and a
strong jet stream pushing across the northern Rockies, will
sustain recent strong west winds through Wednesday.

Ensembles show ridging beginning to influence the western CONUS
extending into the northern plains with warmer and drier weather
conditions for the second half of the week.

FORECAST CONFIDENCE and DEVIATIONS:

Sustained winds have consistently been around 30 to 35 mph
with gusts around 40 to 45 mph. The immediate downslope are off
the Little Rockies in southwest Phillips County have had and will
continue to see slight stronger wind readings. The High Wind
Warning in SW Philips and the Lake Wind Advisory for Fort Peck
Lake continue. After a minor decrease in the winds tonight, a
resurgence is evident in the ensemble model data. Seems fairly
similar to today`s winds, but from 6 AM to Noon across our
western, southwestern, and southern zones, some of our
observation sites could see winds a bit gustier - say 45 mph
gusting to 55 mph. Would be borderline near High Wind Warning, but
will leave for the next shift tonight to have a closer look at
that data.

For Thursday and beyond, have opted to stay close to baseline and
ensemble means capture the pattern well reflecting warmer and
drier conditions with the associated ridge.
