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 [...]

Long Range Model Thoughts

November 26th, 2008 by Steven DiMartino

I know a lot of people are freaking out about the GFS forecast runs past 240 hours from the 12Z to 00Z of last night. I want to say a word on this situation, which shows a “warm” solution setting up. First, please for your own sake, stop yourself from looking at these solutions, cold [...]

The Roller Coaster Begins

November 25th, 2008 by Steven DiMartino

The step down to some really cold conditions will begin after Thanksgiving. I’m using a blend once again of the GFS and ECMWF for the period of Friday through Monday.
A deep trough will dominate the pattern through this period and for some time afterward over much of the East. For the most part, the [...]

Cold And Quiet Through Wednesday

November 17th, 2008 by Steven DiMartino

The forecast area along with much of the Northeast and Mid Atlantic will be under the influence of a deep trough. The trough axis will move from just west of the forecast area to east of the forecast area by Wednesday, which will be a key feature for disturbances that move through the forecast area. [...]

Cold Pattern Sets Up

November 12th, 2008 by Steven DiMartino

The cold pattern that we’ve been waiting for is beginning to set up and will be established by Sunday over much of the eastern third of the nation.
A deep trough will be carved out over the Eastern United States through Tuesday as the northern branch of the jet stream dominates the forecast area. Cold [...]

Stormy End Of The Week Expected

November 9th, 2008 by Steven DiMartino

All of the indications are showing up for the upper level pattern to become increasingly amplified with a defined and deep trough in the East that will lead to a very stormy end of the week.
As the southern and northern branch both amplify towards Thursday, a low pressure system will track towards the Ohio [...]

Major Changes On The Way

November 5th, 2008 by Steven DiMartino

Get ready to say good bye to the ridge in the East or at least the sustained ridge in the East.
A strong cold front supported by a strengthening upper level low and deepening trough will drive through the forecast area on Saturday afternoon. There is a significant potential for strong to severe thunderstorms with this [...]

A Quiet Start To November

October 30th, 2008 by Steven DiMartino

After all the active weather to end October, looks like November will be starting in just the opposite. A strong ridge will dominate the weather pattern at 500 MB through next week, which will support high pressure over the forecast area through the first week of November.
While a strong surface low and deep trough slowly [...]

Evening Thoughts

October 21st, 2008 by Steven DiMartino

I’m sure everyone got a good look at the 12Z model guidance and how different the GFS and ECMWF were for the end of this up coming 10 day period.
Let’s break down what we are looking at with the two maps on the left. These maps can be found at the Penn State E-wall, [...]
