Significant Snow Storm Expected For The Forecast Area

January 9th, 2009 by Steven DiMartino

7:42 AM
I was really tempted to issue a Stage 3 Alert for locastions from Philadelphia through the New York City metro including central New Jersey and the southern Hudson Valley and Connecticut. However, I think it would be wise to wait for 12Z guidance to confirm the trends and developments I am seeing this morning.
My [...]

Significant Snow Finally On The Way?

January 8th, 2009 by Steven DiMartino

7:37 AM
There is a growing agreement in the model guidance that a significant snowfall will impact much of the forecast area.
There’s a lot to discuss, but my ideas which I have presented have not changed overall, but I am able now to get in to some details on how this storm will develop on Saturday.
First, [...]

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 [...]

I just want to say, I got all your emails and yes I know about the GFS and ECMWF is showing on Saturday. See what I mean about not letting your guard down with this clipper? Anyway, I’m going to give my complete thoughts on this entire set up and the impressive cold (and [...]

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 [...]

Pattern Will Continue Activity Through Next Week

January 6th, 2009 by Steven DiMartino

7:41 AM
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 [...]

Discussion on the 12Z Model Guidance

January 5th, 2009 by Steven DiMartino

3:30 PM
The 12Z GFS and ECMWF are out and both do not show any type of storm for next Saturday, but just a simple yet moisture filled cold front passage. Why?
Well, it’s all at 500 MB that gives us the answer! In the 00Z guidance on Thursday night and Friday, a southern branch disturbance phases [...]

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 [...]

Thoughts On The Afternoon Model Guidance

January 2nd, 2009 by Steven DiMartino

9:20 PM
There’s a lot of excitement over the trend of the model guidance towards a colder solution for Tuesday night and Wednesday, specifically the 18Z GFS.
While I can understand the excitement, I want to state that the 18Z GFS does not exactly have the strongest of support. While I agree that a coastal low is [...]

Active Pattern Continues For Next Week

January 2nd, 2009 by Steven DiMartino

7:30 AM
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 [...]
