The snowfall overnight has left many areas with up to about 6 inches of snowfall. It looks like the it was all snow last night. So much for the rain/sleet/snow mix. Many observations reported snowflakes as big as silver dollars last night. One part of the system I did get correct yesterday was the fact that the heaviest snowfall was northwest of the Fort Wayne area. It also is a very wet heavy snowfall as temperatures hovered around 32 degrees all night long. We are also seeing that trowal effect I was referring to yesterday across northwestern Ohio where snow has changed to rain.
Here is the main low pressure area is moving due east through Kentucky. We will still see snow but the heaviest precipitation will be south of the area.
By 1pm the low pulls across southern Ohio. Really taking any heavy snowfall away from our area.
By 7pm the low is no longer a factor. However, there seems to be some lake effect snow bands setting up.
I wanted to show you one more look at what's happening this morning. There is a 500mb or upper level low across the area with a tongue of warm moist air and some areas getting rain this morning.

How can you tell where there are areas of rain using the 500 mb chart showing vorticity?
Cathy,
Sorry for deleting your post. Yes I believe that I was thinking it would be south earlier in the day when the low was progged south of Fort Wayne. So you were correct about that. Every storm this year has tracked considerably north and west of what models progged them. Certainly a frustration for us.
Jake,
Moisture is found at the lower levels usually we define moisture in the 700mb range.
