.DISCUSSION...

KEY MESSAGES:

- Gusty west to northwest winds through this evening

- Dry and warmer weather through the end of the week

WEATHER PATTERN OVERVIEW:

A departing low pressure system moving across central
Saskatchewan and a strong jet stream pushing across the northern
Rockies will sustain strong winds through today. The focus of
strongest winds by this afternoon will shift from the Little
Rockies toward the far northeast corner of Montana, where
sustained winds and gusts will near High Wind Warning criteria of
40 and 58 mph, respectively.

Ensembles show a broad ridging pattern providing steady or
gradually warming temperatures over the next week, along with dry
conditions through at least Sunday.

FORECAST CONFIDENCE and DEVIATIONS:

Winds today were blended with the NBM 90th percentile to better
capture their strength based on latest observations and trends.
This gives medium to high (60-80%) confidence for winds staying
just below High Wind Warning criteria outside of SW Phillips, but
will be most marginal over Sheridan county this afternoon. For
Thursday and beyond, have opted to stay close to the baseline
reflecting high confidence for warmer and drier conditions with
the associated ridge.
