There’s a lot to cover this morning. My primary focus is going to be on the pattern relaxation and then amplification for the medium and long range, but I want to touch on the light snow event for tonight into tomorrow first.

The MJO is on the move and bless the models, they are trying to handle that tricky feature as best as it can. Let’s take a look at where the MJO is today and where I think it is going.

The tropical Atlantic may just be heating up a bit. After weeks of deep troughs producing strong shear throughout much of the tropical Atlantic thus far, a relaxation in the upper level winds is producing much more favorable conditions for tropical cyclone development from the Gulf of Mexico into the central Atlantic.

In previous posts, I stated my doubts of a heavy snowfall as a perfect track with perfect timing was going to be needed to produce a significant snowfall along the coast.

I wanted to make a post about the ideas I have on the potential storm on Sunday, however I saw some data on the model guidance coming in at 00Z and thought better to do some research first before posting. So off I went diving into the KU book for some additional guidance and [...]

The basic idea [...]

I don’t think there needs to be any more debate on whether the NAO will go negative or whether a block will form over Greenland. The fact is that the block has already formed over the eastern North Atlantic (think northwestern Europe) and is starting to retrograde towards Greenland.
Now what does this block [...]

I can bet there will be some out there screaming that winter is over and January is a warm month after the end of this up coming week. A large ridge is going to build over the eastern third of the nation while an upper low digs into Alaska shutting down the northwesterly flow [...]

There is a lot to discuss with this winter storm for Thursday evening through Friday and let me tell you, I had a hard time sleeping with all the thoughts running through my head. So let’s dive in and get started.
First, I think it is important to discuss the trends of the models. I’m not [...]
