Good Saturday to one and all. Rain is pushing back into the bluegrass state today and it will stick around through the rest of the weekend. Things will actually get pretty darn ugly before all is said and done. This pattern is on the leading edge of arctic air that is finally returning to America.

Clouds will continue to thicken up early today as rain breaks out in the west. That rain will then roll toward the east this afternoon and evening. Ahead of the drops, a mix of sun and clouds will allow temps to shoot well into the mid and upper 50s.

The rain will increase tonight into Sunday as another wave of low pressure works across the region. Low clouds and fog will also be noted as temps slowly drop into the upper 30s and low 40s from northwest to southeast later Sunday.

Rainfall totals through Sunday night may reach 1″ in many areas. Here’s the NAM…

That same model run tries to develop another wave of low pressure Monday night into Tuesday morning as the colder air continues to filter in…

If that wave is real, light rain and light snow would be possible during that time. Notice the moisture well back into the cold air in the plains states… that could be a flurry maker later Tuesday around here. That’s being pushed by a true arctic high pressure moving into the heart of the country. That’s likely to slam a lot of the forecast numbers from the models.

The Canadian Model continues to bring the coldest airΒ for the final day of 2014…

That’s a COLD look!

With the infusion of arctic air finally back across North America, we have to watch to see what kind of interaction it can have with the southern branch of the jet stream. This continues to be very active and will try to throw a couple of systems our way late in the week. The new version of the GFS continues to like chance for winter weather…

That model continues to spit the energy out at us in pieces which leads to the winter potential. If all that energy decides to come out at once… it would lead to a much bigger storm that would likely track much farther to the north and bring more rain into the mix. As always, we shall see.

I will have updates later today. Make it a good one and take care.
