 Severe Drought Continues...
The picture above is from - where Mason City, IA is experiencing low water problems like much of central and southern Minnesota. However, in Mason City, the low water problem has enabled them to remove silt from a nearby pond - East Park.

Michigan State University in East Lansing Michigan
This was the scene from Michigan State University on Wednesday after 7" to 9.5" of snow fell Tuesday - early Wednesday. 

Snow Seen From Space
This was the view from nearly 23,000 miles high on Wednesday looking at the heavy snow swath across parts of Indiana and lower Michigan. Some spots got up to 10"
Another View From Space
This is a high resolution satellite image of southern Lake Michigan, which shows the lake all churned up with sand and sediment seen along the southern shoreline. The storm whipped up strong winds and very large waves across the lake... You can also see the heavy snow swath across parts of Indiana and lower Michigan.
Heavy Snow Causes Jackson, Michigan Golf Dome to Collapse
"The first big snow of the season caused the Jackson Sports and Events Dome to collapse this morning. Owner Al Lefere said the wet, heavy snow caused the dome to sag overnight, and this morning when the pressure on the building was increased to make the snow slide off, it fell down through the dome instead."

Light Snow AM Thursday
After a little light snow potential and some light accumulations, our focus shifts into the weekend as another system develops. It's still early and things are likely to change, but let's take a look at what the model are saying:

Less impressive for the Twin Cities as the heaviest stay southeast
Snowfall Accumulation

This model is a little more aggressive in bringing the moisture a little farther north, which would then mean more snow for the Twin Cities
Snowfall Accumulation

The European model almost splits the two model above... it's also important to note that this particular model has been the most consistent since this 'event' looked possible last weekend/early this week. At this point, I would lean more towards the ECMWF with forecasting this upcoming event.
What Does This Mean?
This IS a dilemma... it always is! So many models and so many options. It's important when dealing with potential systems and snowfall events to see how things develop and see how certain weather model solutions converge or diverge over time. I am happy to report that the majority of the weather models are starting to converge, but it's also important to note that the system is still out west in the high elevation, which once it drops out into the southern Plains on Friday, could change entirely.
Storm Placement Midday Thursday
 Storm Track Thru Early Saturday

That's all for today, thanks for checking in and have a wonderful rest of your week! Stay tuned on the upcoming 'potential' snowfall event. Don't forget to follow me on TWITTER!
