MJO on the move and a return of a real wintery threat showing up

10:05 AM
Premium Content
Over the past three weeks, the 500 MB pattern has been generally unfavorable for any significant winter storms for a variety of reasons.  At first, the overwhelming strength of the negative NAO suppressed any potential for Sub Tropical disturbances to interact with the cold air at place, leading to a cold and dry [...]

December Thoughts- the cold is on the way

9:45 AM
Over the past several weeks I have been strongly hinting at a cold start to December.  The various indicators I’ve been looking at to make these statements include the Stratospheric anomalies of late, the development of the MJO state, and the growth of snow cover over much of Alaska and northwestern Canada.
As the models [...]

Thoughts, Theories, and The Future of this Pattern

1:30 PM
I want to start this post by saying that what I am about to write is a theory, an unproven theory at that, which has been rattling around in my brian for the past several days.
As we all know, the Tropical Atlantic season has been less than stellar with very few tropical systems impacting [...]

What has caused the heavy rainfall this month?

9:52 AM
June has seen some very impressive rainfall amounts with many locations well over an inch above normal.  Even some locations double the amount of normal rainfall.  While a continuous onslaught of showers and thunderstorms have impacted much of the Mid Atlantic, and specifically the New York City and Philadelphia metropolitan areas, other locations have [...]

Negative EPO Fights Back

9:12 PM
The winter pattern is still lingering in the northern branch of the Polar jet stream as we continue to see the continuation of a back and forth game between the North Atlantic Oscillation and the Eastern Pacific Oscillation.  As the negative NAO begins to collapse once again early this coming week, the negative EPO [...]

And In This Corner!

7:57 AM
A battle is setting up of atmospheric proportions between the more progressive Pacific pattern that is being established over much of the CONUS and a very strong negative NAO that is forming over the north Atlantic.  For the most part, aside from the negative NAO, there isn’t much in the way of blocking over [...]

Is Winter Over? Not By A Long Shot!

7:18 AM
I’ve gotten a lot of emails the past 24 hours if this is it?  Is this the big storm and then winter is over?  Well, let’s look at all the data.  I know many people like to focus on the Pacific and only the Pacific, but I like to take a more round about [...]

The January Outlook

7:40 PM
December has come and gone along with all the holiday cheer, it’s time to look to see what the rest of January holds for the forecast area.  Will the negative NAO be a major factor?  Will the Pacific get back into the game or will January be a warm and boring month?
The basic idea [...]

What’s Going On In The Pattern

After a lot of thought and about 150 curls at the gym, I wanted to write about what I think will unfold in the pattern for the next two weeks.  
I’m sure everyone is freaking out about the latest in the crazy guidance seen on the long range GFS and ECMWF guidance.  The big scare [...]
