Afternoon showers knocked temperatures well of the projected pace here in Billings today but we should still see pleasant temps once it is all said and done.
By later this evening a regime change will start to take effect as a surface trough dips into our area from southern Canada, bringing with it much cooler temperatures and significant moisture.
This sets us up for unseasonably cool and rainy day to start the work week on Monday. High temperatures are likely going to stay in the 50s and there is a good chance that much of Montana sees 0.25-0.5” of rain over the course of the day.
There is some significance to a forecast temperature in the 50s for Monday, as that would mark the third time this month that the high temperature here in Billings has failed to reach the 60 degree plateau. This would be the first August on record that this would have occurred in Billings since 1934 when records began to be tracked.
This cold, moist air mass could have impacts on those planning to travel the Beartooth Pass on Monday, as snow levels are expected to drop to around 9000 feet, potentially creating sub-standard driving conditions.
The rest of the week will see temperatures rebound to around the seasonal level and skies clearing out. Right now Thursday looks like the warmest day of the week, with temperatures forecasts to creep up into the lower 80s.
