Arctic Express On The Way Along With More Snow Potential

January 8th, 2009 by Steven DiMartino

7:49 AM
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 [...]

Thoughts For The Weekend And Beyond

January 7th, 2009 by Steven DiMartino

8:41 PM
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 [...]

This Pattern, More Than Meets The Eye

January 7th, 2009 by Steven DiMartino

7:51 AM
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 [...]

Active Winter Weather To Continue

January 5th, 2009 by Steven DiMartino

9:58 AM
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 January Outlook

January 1st, 2009 by Steven DiMartino

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 [...]

Clipper Watch!

December 30th, 2008 by Steven DiMartino

10:32 PM
The Alberta Clipper that will impact the forecast area tomorrow morning through the rest of 2008 is currently over central Ohio. The largest pressure drops are slightly more south than expected, but nothing significant in nature.
Precipitation is quickly building over southwestern New York, however at this time only Buffallo is reporting any snowfall. Therefore [...]

Working The Night Away

December 30th, 2008 by Steven DiMartino

9:46 PM
Good evening everyone!
The trend by the model guidance clearly has been away from a significant storm for Friday afternoon and evening. The reason why spands several reasons. The first is that the disturbance associated with the clipper is actually much weaker than any guidance suggested. Notice in the days following, the GFS, ECMWF, and [...]

Light Snow To Ring In The New Year

December 30th, 2008 by Steven DiMartino

7:12 AM
While there is a lot of uncertainty for the end of the week, model guidance is at least converging on the idea of a strong Alberta Clipper moving through the forecast area on Wednesday.
Today, a much weaker disturbance will move to the north of the forecast area this afternoon. Currently, this disturbance is enhancing [...]

Active Pattern Developing While Models Have A Difficult Job Ahead

December 27th, 2008 by Steven DiMartino

12:54 PM
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, [...]
