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, [...]

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 [...]

Heavy Ice And Rain To Continue Through This Afternoon

January 7th, 2009 by Steven DiMartino

7:27 AM
The forecast for the next three days is obviously going to be the most active in the next 24 hours.
Currently, a coastal low pressure system is developing off the New Jersey coast. Winds along the coast are beginning to turn to the northwest over southern New Jersey and northeast along Long Island, clearly indicating [...]

Colder Environment Setting Up Icy Weather For Interior

January 6th, 2009 by Steven DiMartino

7:27 AM
The first observation I noticed throughout the forecast area was how dry the air was. This is a big deal everyone for one simple reason. Evaporational cooling.
The precipitation seen over Delaware and Maryland will slowly push north today, as high pressure gives way over the next 8 to 12 hours. Clouds will continue to [...]

Icy Conditions On The Way

January 5th, 2009 by Steven DiMartino

9:21 AM
A very dangerous situation is developing for parts of the forecast area that can lead to some significant icing over parts of the interior by Wednesday morning. These types of forecast can be tricky to forecast because the line between a heavy rain and over 0.25″ of ice is like walking a tight rope [...]

Windy End To 2008

December 31st, 2008 by Steven DiMartino

7:47 AM
The new coastal low pressure system is really starting to take shape right over southern New Jersey and the immediate coastal waters, specifically around Atlantic City.
Through the rest of today, rain and snow showers will change over to all snow showers throughout the entire forecast area. Temperatures will fall through the afternoon through the [...]

The 12Z Guidance And Thoughts For Friday

December 29th, 2008 by Steven DiMartino

8:59 PM
If you put your ear to the ground, you could hear the fall of a million snow lovers faint to the ground after seeing the 12Z GFS, which basically if taken verbatum would produce a significant snowfall for most of the forecast area, save southern New Jersey (even that location would still get measureable [...]

Winter Returns, But Questions Remain

December 28th, 2008 by Steven DiMartino

10:22 AM
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 [...]

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, [...]
