Area Forecast Discussion

KEY MESSAGES

- Dry weather conditions are expected through much of the rest of the weeek with temperatures remaining near seasonable.

- Temperatures will look to warm over the upcoming weekend with highs across NE Montana on Sunday pushing into the 50s and 60s.

DISCUSSION

Light winds and patchy morning fog are expected Wednesday morning, especially in the river valleys. Otherwise, look for temperatures in the 20s and 30s to start the day.

Upper ridging will gradually progress eastward through the week helping to maintain mainly dry and seasonable weather conditions. An upper trough will push through the region on Friday with a cold front Friday night and Saturday. For now, ensembles keep much of the precipitation chances off to the south and west of the CWA.

Upper ridging looks to rebound over the weekend. Look for largely dry weather and warming temperatures under the larger scale subsidence as high temperatures by Sunday reach into the 50s and 60s.

FORECAST CONFIDENCE & DEVIATIONS:

No major deviations to NBM were used for this forecast cycle. There remains low confidence on patchy fog for Wednesday morning. Otherwise there is strong consensus in support of mostly dry and seasonable weather through the week.
