KEY MESSAGES

- Cooler temperatures this weekend across NE Montana along with chances for light rain showers today.

- Closer to average temperatures and additional rain chances late Tuesday into Wednesday.

DISCUSSION

WEATHER PATTERN OVERVIEW:

Following a cold front this morning, we're seeing a return to closer to average, more mild temperatures for the next few days. Highs will be in the 40s and 50s through Tuesday while the upper ridging weakens with embedded shortwaves tracking through the region and becomes more zonal over Montana. These will provide enough forcing for ascent for scattered rain coverage again by about Tuesday night into Wednesday. Cooler temperatures look to follow the shortwave action late in the week as conditions dry out.

FORECAST CONFIDENCE & DEVIATIONS:

Blended HRRR for day 1 winds and 50% NBM90 for day 1 wind gusts. Increased PoPs for this afternoon following the increased saturation from preliminary rainfall that did not reach the ground.

Will caution however given the spotty coverage and light nature of the precipitation chances at times this week, confidence on exact locations and amounts is below average despite agreement on the synoptic view.
