DISCUSSION

KEY MESSAGES:

- Warmer than normal temperatures today will fall to near normal on Friday.

- Warmer than normal temperatures return on Sunday and continue for several days.

- Dry weather is expected for the next several days.

WEATHER PATTERN OVERVIEW: A nearly zonal flow today will transition into a deepening trough Thursday and Friday as several shortwaves push through the northern Rockies. With the amplifying flow, by the weekend a ridge will move across the western states.

A Pacific cold front will move through the area today which will bring west winds that should mix out the inversions that have kept temperatures colder in valley along and north of US 2 the last few days. Another cold front moves though Thursday night that will lower temperatures to near normal for Friday. Moisture will stay to the south and west of the forecast area with these systems.

Saturday and Saturday night, a warm front is expected to move east across the area which will bring a return to above normal temperatures. If skies clear with light winds, nighttime fog is possible.

An upper ridge will prevail early next week with dry weather.

FORECAST CONFIDENCE & DEVIATIONS:

Confidence on temperatures today is low north where snow cover linger and uncertainty on how much west winds will mix out the inversion and high south where the ground is mainly bare. Used NBM 75 for highs in most areas with tweaks lower in parts of the north. No other deviations from NBM in forecast.
