This morning I discussed my concern for convective snowfall along the New Jersey coast in the public post. I wanted to give more details on this threat this morning.
This morning I took a look at the latest sounding from OKX, which is on Long Island. Granted, the sounding is still a bit of [...]

Pacific pattern begins to take hold by this weekend

March 24th, 2009 by Steven DiMartino

7:29 AM
The exit of an area of low pressure on Friday morning will finally break the grip of Arctic air over the forecast area that has influenced the region for the first half of this week. Warmer modified Pacific air will flood into the forecast area on Friday as high pressure positions itself to the [...]

March 20th, 2009 by Steven DiMartino

7:21 AM
The model guidance has really come into strong agreement over the past 24 hours with respect to the overall upper level pattern and the development of surface features through the middle of next week. There are two key players that will drive the up coming pattern for the CONUS. The first is the strong [...]

Models come into agreement with back door cold front

March 18th, 2009 by Steven DiMartino

7:10 AM
It’s always nice for a forecaster when all the medium range model guidance comes into a general agreement in any situation, especially with details of a back door cold front in the Spring. There is now strong support to push an impressive back door cold front through the entire forecast area on Sunday evening, [...]

A Back Door Cold Front That Means Business

March 17th, 2009 by Steven DiMartino

7:14 AM
While many think of Spring as a time of green grass returning, warmer temperatures, and a quieter weather pattern; Spring also means the return for the difficult forecast phenomena of a back door cold front. A back door cold front is basically a cold front the develops over the Canadian Maritimes and drives southwestward [...]

The disturbance that brought a few scattered showers to southern New Jersey is quickly exiting the region this morning as clouds quickly exit into the Atlantic. While the low pressure system was not strong, it was still able to keep temperatures cool and skies overcast over southern New Jersey.
High pressure is building into [...]

A Major Cold Fronts, Front And Back

March 16th, 2009 by Steven DiMartino

6:16 AM
The upper level pattern continues to evolve over the next seven days, but the theme from this winter remains true, with a bit of a twist. With the northern branch of the Polar jet stream continuing to lift north, the influence of the negative EPO pattern will continue to weaken, however the trough that [...]

The Transition To Spring Begins

March 15th, 2009 by Steven DiMartino

10:16 AM
Spring will officially begin on March 20th according to the calendar. Looks like the upper level pattern is going to actually help out in bringing Spring-like conditions to the forecast area. While the northern branch continues to sway between a negative NAO to a negative EPO pattern, the influence of the northern branch will [...]

Personally, I love these types of days. While I have friends who love the sun, hot temperatures, and heat that is to come (trust me), and you know who you are, personally I love cloudy days. Days like are a perfect time to do some reading, go to the movies, get ready for March [...]

From One Cold Pattern To Another

March 14th, 2009 by Steven DiMartino

6:46 AM
The first few days of transition from the negative NAO pattern to the negative EPO pattern will likely play on your senses in thinking that Spring is finally here for good. Not so fast! While high pressure will reposition itself off the coast on Tuesday and Wednesday, leading to mild conditions, the influence of [...]
