A weak disturbance and cool front moving through today may create a few cloudy intervals and an isolated shower or two. Then after a mild weekend a strong cold front on Sunday evening will bring cold weather and probably hard freezes and some snow early next week.
The air mass moving in Sunday night should be cold enough for snow at all elevations, but the questions are whether there will be substantial precipitation and whether that precipitation will last long enough to change to snow. Right now it appears likely that there will be at least measurable snow Monday or Monday evening along the Front Range and adjacent plains. But it appears less likely (but not yet ruled out) that there will be more than 4 inches in the lower elevations. Get ready for widespread frosts and freezes early next week too.
