The Arctic Express is on the way, and this has nothing to do with Santa Claus, however for some it might seem like Christmas morning all over again.
The negative EPO is going to be doing a heck of a job driving arctic cold air into the eastern two-third of the nation through next week. [...]

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 [...]

I can tell the excitement is building for Saturday based on the emails that have flooded my inbox this afternoon. Yes, the model guidance, and I mean all model guidance, is picking up on the potential for the Alberta Clipper on Saturday.
Before we get into the model guidance, let’s get back to the basics [...]

Taking a look at the pattern via surface maps, the potential and interest in the pattern through this weekend into next week would best be described as boring, especially the GFS. However, if one was to look at 500 MB, they would come away with a totally different perspective on this pattern that is [...]

The east wind we’ve been expecting is finally kicking in and allowing temperatures to rise quickly over much of southern and central New Jersey. For example, in my own back yard since the wind switch about 30 minutes ago, temperatures have jumped from 31 degrees to 33 degrees with a steady rise indicated. Similar [...]

Right now, if you are along the immediate coast, your snow and ice worries are all but over. The strengthening warm air advection off the Atlantic supported by the developing 850 MB low over the Tennessee and Ohio Valley has warmed the majority of the atmosphere above freezing, thus producing all rain for coastal [...]

There is a lot more opportunities for winter weather over the next 10 to 15 days as a deep trough digs in the East and a ridge builds to northern Alaska over the next several days. The negative EPO is returning and the pattern over the Atlantic is best described as nuetral in terms of [...]

At this time, my thoughts for the storm on Tuesday night through Wednesday have not changed. However, I wanted to go over again how I think everything will evolving from Tuesday afternoon through Wednesday afternoon.
Tuesday Morning: On Tuesday morning, clouds will increase throughout the forecast area. High pressure will be giving way to the [...]

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 [...]

The new year is certainly starting off with a bang this year, unfortunately that does not mean snow for all.
The main theme through this period will be the changing Pacific and Atlantic patterns. The negative NAO block will begin to weaken, however already the ECMWF is backing away from the complete collapse idea and [...]
