Predicting tonight's exact low temperature is a bit more difficult than usual.
That's because an area of high pressure is moving right overhead, clearing out the clouds, and creating calm conditions across the region.
With abundant snow on the ground, temperatures should drop pretty quickly after sunset, bottoming out near 0°.
Chinook winds are expected to develop overnight, which will further complicate the situation.
As these west-southwest winds get going, temperatures will actually start to climb before sunrise on Tuesday.
So, many of you may actually wake up to warmer temperatures than when you head to bed tonight.
High pressure keeps us dry and clear through Tuesday, but clouds will begin to return Tuesday night and Wednesday as a weak storm system approaches Montana.
