It's a "Watch" Not a "Warning"
But Consider Yourself Warned...

The followng text is from weather.com: 

A WINTER STORM WATCH REMAINS IN EFFECT FROM TUESDAY AFTERNOON THROUGH WEDNESDAY EVENING.

* TRAVEL AND COMMERCE ACROSS THE WATCH AREA MAY BE SEVERELY IMPACTED BY HEAVY SNOW AND SIGNIFICANT BLOWING AND DRIFTING SNOW TUESDAY NIGHT AND WEDNESDAY.

* HEAVY SNOW AND BLOWING SNOW WILL MAKE CLEARING OF ROADS DIFFICULT TUESDAY NIGHT INTO WEDNESDAY. CONDITIONS WILL IMPROVE GREATLY INTO WEDNESDAY EVENING AS THE WINDS DIE DOWN.

* NUMEROUS EVENT CANCELLATIONS INCLUDING SCHOOL CLOSURES ARE POSSIBLE... AS WELL AS FLIGHT DELAYS AND CANCELLATIONS.

* HEAVY SNOW IS POSSIBLE ACROSS THE WATCH AREA WITH THE POTENTIAL FOR TOTALS IN EXCESS OF A FOOT BY WEDNESDAY EVENING... ESPECIALLY SOUTH OF A MUSKEGON TO ALMA LINE.

According to this radar map, it's already on its way and will hit west Michigan Tuesday evening.

[Note: My daughter Kim is in Chicago a few blocks from the lake. We typically get her weather about five or six hours later. Here is what they are bracing for: * SNOW ACCUMULATIONS IN EXCESS OF A FOOT ARE EXPECTED OVER MUCH OF THE WATCH AREA FROM TUESDAY AFTERNOON
* THROUGH WEDNESDAY AFTERNOON. LOCALIZED TOTALS IN EXCESS OF 18 INCHES ARE POSSIBLE...ESPECIALLY NEAR THE LAKE.] 88736
