Good Monday evening gang. Snow is on the way to the bluegrass state as we head into Tuesday and Tuesday night. This is all in response to a storm system rolling out of the south and up the east coast over the next few days.

Rain will develop overnight and will continue into early Tuesday before mixing with and changing to snow as cold air quickly dives in. Light accumulating snows are a good bet for much of the state in the afternoon and evening. There is likely to be a band of moderate to heavy snow working eastward behind the low. This is the ‘deformation zone’ area I talked about over the weekend and this is something for us to watch. Areas getting under this can pick up a quick inch or two of slushy snow.

Northwesterly winds will set in Tuesday night and early Wednesday with snow showers and flurries bringing another chance for a light accumulation across the eastern half of the state.This may even get a little push from Lake Michigan and you can actually see that on the last panel of the NAM…

The GFS Ensembles are very similar…

I will get a snow map out with the overnight update. Temps will dip into the 20s by Wednesday morning and that should cause some slick spots to develop on area roads.

Looking down the road we find a major trough digging into the eastern half of the country as we start the new year. This should provide a heck of a blast of cold with several snow chances next week.

European Model

Canadian Model

Every model is all over a deep trough across the east next week. Every model not named the GFS, that is. The model only shows it every other run… but it’s the GFS. I read a discussion from NWS in Jackson calling the European the outlier with no support from any other model. If by any other model they mean the GFS then they are correct. The GFS is actually the outlier with no support period. Well… every other run of the GFS, anyway. Confused yet? Good… that’s how I like it.

I will have a full update later tonight. Until then… track the rain into town…

Have a great evening and take care.
