Winter Blast Update

Here’s the latest update on the Winter Blast we’ve been talking about here on the blog:

There is a “Winter Weather Advisory” active for the area from 4 PM on Thursday to 7 PM on Friday.  This is all a result of the rain changing to snow, along with the development of high winds that we’ve been spotlighting here on the blog and in our on-air forecasts.  This will make for dangerous and difficult travel from tomorrow night through the day on Friday, especially if you’re traveling to/through northwest Indiana – all as a result of lake effect snow developing and persisting through the day on Friday.

Winter Weather Advisory


Accumulating snow is expected across NE Indiana and NW Ohio.  But, it’s a very challenging forecast.  It’s challenging because we have rain changing over to snow (So, when does that happen? Timing is everything in this situation.  Right now, it looks like it will begin around 7 PM Thu).  However, the ground is warm, too.  So, even when the snow gets going it will not be accumulating right away.  Plus, when the lake effect snow sets up, it can create wide variations in snowfall accumulations over a relatively short distance.

Based on the data we have, and taking into account all of the above factors and how the storm system appears to play out, here are the predicted snowfall totals by the end of the day on Friday.
