June 5th, 2009 by Steven DiMartino

Sometimes in life there are important trade offs that we must make. In terms of weather conditions, the forecast area will go through a very wet, raw Friday to get to two days of exceptional weather conditions this weekend.
This morning, an area of low pressure developing over central North Carolina. As the upper [...]

Cold Air Returns, But Not For Long

March 9th, 2009 by Steven DiMartino

The end of the week is expected to be rather quiet, but rather chilly for the middle of March. A strong cold front will exit the forecast area on Wednesday night with strong Canadian high pressure building into the region from the northern Plains. At 500 MB, a strong upper low located at 50 [...]

Cold Air Slow To Leave, But Eventually Will

January 28th, 2009 by Steven DiMartino

6:35 AM
The cold air is being rather stubburn to leave the forecast area, however the signals are showing up as winds slowly shift to the east. Before the warm air gets into much of the forecast area though, ice is going to be a significant concern through the morning hours from Philadelphia through central New [...]

Another Tough Forecast On The Way

January 26th, 2009 by Steven DiMartino

7:30 AM
You know, I would love to forecast an all snow event at some point. Just look at the QPF, multiply by 10 or 12, then here’s the snow map. Oh no, not this winter. haha
Model guidance is still all over the place on exactly how this storm will play out for the forecast area, [...]

Welcome to another start of the week! Well for some of us, MLK Day means that many will be off today while others get prepared for Inaugreation Day tomorrow, however the weather never takes a day off, so off I go!

Cold And Stormy Pattern To Return For New Year

December 22nd, 2008 by Steven DiMartino

7:27 AM
There are growing indications that 2009 will come in with a bang, at least in the terms of weather. There are signals that are becoming much more stronger for a cold and stormy pattern to develop in the last few days of December and through much of early January. The first key is that [...]

Difficult Forecast With Huge Bust Potential And Significant Ice And Snow Amounts

December 19th, 2008 by Steven DiMartino

12:21 AM
You know, model guidance is suppose to get better and into strong agreement less than 24 hours away from an event. Unfortuantly for the forecast area and this forecaster, that was not the case tonight as the GFS went extreme warm and the NAM/WRF went colder.
So with no trust what so ever in [...]

Thoughts For Next Week

December 6th, 2008 by Steven DiMartino

While I am breaking down the current radar and satellite images, I think it is a good time to discuss the latest guidance with the set up for next week.
First and foremost, it is NOT wise to try to figure out the rain/snow line positions of any storm 4 or 5 days out. You can [...]

What’s Going On In The Pattern

December 3rd, 2008 by Steven DiMartino

After a lot of thought and about 150 curls at the gym, I wanted to write about what I think will unfold in the pattern for the next two weeks.
I’m sure everyone is freaking out about the latest in the crazy guidance seen on the long range GFS and ECMWF guidance. The big scare [...]

A Clipper Threat For Sunday Marks The Medium Range

December 3rd, 2008 by Steven DiMartino

Can you hear that? Can you hear the beat of excitement grow for this Sunday? There are even hints on the morning news of a snow threat. Well, now let’s wait for a moment before we all start doing snow dances and watching individual model runs at 3 AM. Does the upper level pattern support [...]
