Premium Content:
9:25 AM
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.

Tropical Weather Update for Wednesday, August 5 2009

5:25 AM
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.

Major Changes And The Reasons Behind Them

8:47 AM
An extremely rare and extremely difficult forecast is evolving for the forecast area this morning.  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.  The model guidance and more importantly, the atmosphere [...]

The basic idea [...]

Thoughts On The Greenland Block Developing

7:12 AM
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 [...]

Thoughts For The Next Few Weeks

1:10 PM
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 [...]

Winter Storm Discussion And Thoughts

 
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 [...]
