(WXYZ) — We will potentially see our first big snow next week. This is a VERY early look, so we shouldn't focus on the exact numbers yet. As with any forecast more than a few days out, this will change as we get closer.

After a mild weekend, colder air will move back into Michigan Sunday night. Forecast models suggest this cold air will collide with an ample amount of moisture from a storm system south of us. If this storm systems gets "cut off" from the main flow of the jet stream, it could stall out over Michigan for several days next week. This would lead to cold days with widespread rain and snow Monday through at least Wednesday.

How much snow will depend on how much moisture is still available as it gets colder Tuesday and Wednesday, and how far to the north or south the low pressure is from us. Right now the best day to see most of the accumulating snow is Tuesday.

The potential is there for central Michigan to see up to 10 inches of snow. However, if the wind stays out of the southeast and is coming off the lakes, Metro Detroit may stay warmer and see more rain than snow. That may keep totals down to a few inches, but higher totals would still be possible in central Michigan.

Takeaways:
*Rain changing to snow Monday
*Accumulating snow may impact travel Tuesday and Wednesday.

Stay tuned to the forecast for updates as we get closer.
