KEY MESSAGES

- Dry weather with above average temperatures are expected to continue for the next several days.

- Windy conditions begin tonight lasting into Saturday and again late Sunday.

DISCUSSION

A broad upper trough over the Gulf of Alaska will allow storm systems to crash into British Columbia over the next several days with drier/weaker systems emerging over Alberta and Sask.

This will bring some instances of winds for northeast Montana while temperatures are expected to remain above normal. The first weak front will move in late tonight/Saturday. A wind gust to 58 mph has a low confidence (30-50%) of occurring but issued a High Wind Warning to cover.

Also issued a Lake Wind Advisory for Fort Peck Lake tomorrow from 7 am till 4 pm as wind gusts of 30-35 mph look to occur.

Another weak front moves in late Sunday for an uptick in winds, but not as strong.

Ridging aloft builds back in for most of next week, although low level easterly winds could inhibit full warming potential.
