The theme going forward will likely crush the forecast for anyone going for a warm January. The combination of a strong negative EPO and the postion of the upper low over eastern Canada will support a very cold air mass to dive into the eastern two-thirds of the nation.
There can be no doubt that [...]

The pattern will continue to amplify towards the end of the week and into the weekend. I want to touch on some points about the overall pattern first before discussion the forecast.
There is some discussion that the pattern appears to be like a return to mid December with a raging postive NAO. This is [...]

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 [...]

There are some interesting themes that are coming from the medium range guidance over the past few runs that need to be addressed as we move into the first full week of January, 2009.
The first theme that the model generally agree on is that the block over Greenland will significantly intensify to build down [...]

The up coming forecast for the middle and end of this week is going to be very difficult. The overall idea here on all model guidance is that the negative NAO block will be established while a series of clippers move through the forecast area. One clipper intensifies, and produces a strong Miller B [...]

Or maybe I should say meteorologist like me who are shaking their heads while looking at the model guidance. When we have a difficult pattern unfolding, the best thing to do is not get bogged down with details of rain/snow lines and what not.
Let’s think about this set up for a second.
One, [...]

The pattern in this period will be evolving into a cold and very storm pattern. In this post I will naturally explain the step down into what will make a lot of individuals in the I-95 corridor very happy, if you like snow at least. Then I will touch upon my thoughts for the [...]

The promise of a negative NAO has been seen on guidance for some time, but has never materialized because the way the model produced the negative NAO just didn’t make any sense. The atmospheric set up right now over the eastern Atlantic and Europe strongly supports the development of a negative NAO over the [...]

There are growing indications that 2009 will come in with a bang, at least in the terms of weather. There are signals that are becoming much more stronger for a cold and stormy pattern to develop in the last few days of December and through much of early January. The first key is that [...]

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 [...]
