High pressure remains in control headed into Sunday, keeping us sunny and mild. The high pressure will begin to weaken and move east which allows a cooler and unsettled airmass to move in. A cold front also swings in from the north and stalls out south of Great Falls. This briefly cools us down Monday night through Wednesday but high pressure regains control for the end of the week. We go right back to mild temperatures as a result.
