Next winter storm potential Sunday-Monday!

Next winter storm potential Sunday-Monday!

Our next winter storm is in the works for Sunday into Monday - and it's all about the freezing line!  So often we see the Ohio River as the dividing line between wet and frozen, and this could be the set-up Sunday and Monday. 

First off, the storm is still several days away and the forecast is highly subject to change, even the day of the storm, changes will likely be made.  This is a situation where temperatures could range 25 degrees within about 50 miles.  So, stay tuned to forecast updates through the weekend.  Why do we show you these maps now?  I guess to prove the chances of this storm happening are going up and so you know that we're not just making it up.  It's not hype, we just want you to be ready.

So, if you're ready, follow along with the maps below.

The first map is Sunday through early Monday morning with rain likely south of the Ohio River, freezing rain and sleet north.  Notice the freezing line possibly right over the river.

The next map shows the storm as it's beginning to move out, at the same time, the freezing line dives south, and much more of our viewing area will have frozen precipitation chances (freezing rain, sleet, and snow). 

Now the next two maps show the GFS and GEM (Canadian) weather models and their snowfall total accumulation.  Notice, most of the snow is staying just north. Areas along and north of I-70 (central Indiana and Illinois) could get hammered with more heavy snow.  But, what about us??

Well, the last three maps show the precipitation type.  Freezing rain = yellow.  Sleet = red.  Snow = blue.  These maps are from the GFS weather model, and show quite a wintry mix for a long period of time!   These three maps are from 1pm Sunday through 1pm Monday.  You can see things are staying about the same for the first two maps (1pm SUN - 1am MON), then the colder air drops south and thus increasing snow chances early Monday. 

To sum this up, ice and snow accumulations will be possible by early Monday with major negative impacts to area roads.  It's too early to give out a specific accumulation of ice and snow.  At this time, it appears Indiana could get hit the worst with accumulations.  Rain is more likely south of Louisville.  Again, stay tuned!!
