A good old fashioned snowstorm looks to be brewing for the region this weekend. There is still a lot we don’t know yet since we are three days out, but we are getting a clearer picture than we’ve seen the past few days. Snow looks to move into the region late Friday night, after Midnight. Waves of snow will be in the area until Sunday afternoon. The rain/snow line will also set up shop somewhere in our area. Every model varies right now on placement of that line.
The Canadian has this:
That leads to some hefty snow totals.
The GFS has a pretty similar idea. Again, the rain/snow line is close to the Ohio River for some of this event.
Snow totals on the GFS are lighter.
The NAM does not see the whole event yet, but it’s a healthy hit for what it sees.
Snow totals through Saturday evening look like this. NAM is juicier than the other models. NAM is also not in its best element this far out, so take with a few grains of salt.
The Euro was the coldest of the models, but it has now also brought the rain snow/line into Southern Indiana. Gives a healthy hit of snow at the onset, but quickly changes to rain for folks south of the US-50 corridor.
It’s a very healthy hit of snow, though, for much of Indiana. The totals from US-50 and southward into Kentucky arrive before the rain and would be washed away by the rain.
This storm is not on shore and fully sampled in our upper air network just yet. It will be until Friday before I’ll issue a specific forecast with snow totals expected. But a general 1-3″ looks likely for much of Southern Indiana and parts of Illinois and Kentucky at this point. There will likely be a swath of 2-4″ or even 3-5+” snow somewhere, but that placement just can’t be known with certainty this far out. Figuring out how far north the rain/snow line goes will be key. And there is too much variance in the data to know right now.
Either way, I’d be preparing for some snow this weekend. Travel looks difficult over a good chunk of the area Saturday. More updates to come. Be sure to follow me on Facebook and Twitter for frequent updates.
