Good Sunday everyone. This is going to be a very busy place over the next several days as we watch a once in a lifetime (at least) event unfolding across the eastern half of the country. Hurricane Sandy is going to join forces with a huge dip in the jet stream and make the transition into a monster of a nor’easter. The models have pretty much settled in on the track and evolution of this storm and it is likely to have a significant impact on our weather here in the bluegrass state. A Winter Storm THREAT continues for eastern Kentucky.

We actually have some wintry stuff to talk about before that monster throws precipitation our way. Rain is likely today across the eastern half of the state. Temps are going to be chilly and colder air will slowly filter in from the northwest later tonight. That will likely cause a mixture of rain and wet snow across the higher mountains. The NAM shows the areas most likely to see some flakes tonight and Monday morning…

Monday is when things really to take a turn toward the historic side. Sandy will be approaching the New Jersey coastline during the afternoon and will then push west and southwest from there. This will be a devastating storm to much of the Mid Atlantic and northeast.

As Sandy transforms from a hurricane into a nor’easter, we will start to feel the impact around here. Check out the track of the storm from the NAM:

 The storm looks to do what we’ve been talking about for a while, now. Work toward the west and southwest toward the eastern Ohio Valley. The GFS says “I approve this message”…

 

 You simply cannot get much better agreement than that on any event, let alone something historic. The reason for the southwesterly motion is because of a huge block across eastern Canada and Greenland. Can the models change? Yes… but time is running out.

What does it all mean for us?

– A shield of rain and snow will quickly work in from the northeast late Monday and Monday night. This is going to be awesome to watch on radar!

– A corridor of heavy snow may set up across parts of eastern Kentucky Monday night through Tuesday night. This is one of those setups that we see the heavy precipitation falling as snow and the lighter stuff falling as a mix of rain and snow.

 – The potential for several inches of wet snow is certainly there for eastern parts of the state. That’s why we have the Winter Storm THREAT…

– Many people are asking how snow can accumulate with a warm ground. I can give you many, many examples of where it snows faster than it can melt. That’s what is likely to happen this go around in some areas and if the models are right, power problems could arise from eastern Kentucky into parts of Ohio, West Virginia and Virginia.

– Rain and a mix of rain and snow is likely to work pretty far westward into central Kentucky (I-65) during this time.

– Wraparound rain and snow showers may carry us all the way through Halloween and into early Thursday.

– The winds are going to be a huge player across central and eastern Kentucky. Gusts may top 40mph and could even approach 50mph in the far east from Monday night through Tuesday.

I hope to be able to get more specific on the snow chances later today and that may come with a first call map. Updates will be coming your way as needed. Have a great Sunday and take care.
