The Cold And Snow Will Not Go Away Through Next Week

January 9th, 2009 by Steven DiMartino

7:30 AM
The Arctic Express is on the way, and this has nothing to do with Santa Claus, however for some it might seem like Christmas morning all over again.
The negative EPO is going to be doing a heck of a job driving arctic cold air into the eastern two-third of the nation through next week. [...]

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 [...]

New Year’s Eve Snow And The Developing Cold And Stormy Pattern

December 29th, 2008 by Steven DiMartino

7:26 AM
The negative NAO pattern is well on the way of developing and the first clipper that will impact the forecast area will help to enhance the 50/50 low that will be a major player in the later pattern. First though, let’s discuss the next three days.
High pressure will slide through the forecast area today [...]

9:45 AM
In case anyone woke up this morning and was worried if they slept for the past three months, yes it is December 28th and yes it is near 60 degrees already.
Enjoy the warm conditions while you can because they are about to come to an abrupt end. A strong cold front over the eastern [...]

Thoughts For The Next Few Weeks

December 21st, 2008 by Steven DiMartino

1:10 PM
I can bet there will be some out there screaming that winter is over and January is a warm month after the end of this up coming week. A large ridge is going to build over the eastern third of the nation while an upper low digs into Alaska shutting down the northwesterly flow [...]

Quick Thoughts And I Need Some Coffee

December 19th, 2008 by Steven DiMartino

5:53 AM
Okay guys, I’m back from what was basically a nap. Here are my thoughts as I see the situation right now.
First, the air mass HAS set up colder. I took a quick peak at the 06Z guidance, which is in slightly better agreement. The first thing I noticed with the 06Z data was [...]

00Z NAM Thoughts This Evening

December 16th, 2008 by Steven DiMartino

10:16 PM
Looking past tonight, the forecast period for Friday is beginning to enter the range of the NAM/WRF data. Now, I first want to say that it is NEVER a good idea with going with a verbatum forecast from the NAM past 66 hours. However, I want to high light some of the features in [...]

The Roller Coaster Begins

December 7th, 2008 by Steven DiMartino

Are you ready for some volatile weather! Well, you better be because over the span of the next three days we are going to see a large variety of weather conditions over the forecast area.
For the rest of today, the coastal low that has redeveloped off the coast has continued to deepen rapidly, producing a [...]

Cold Conditions On The Way. What About Snow?

December 2nd, 2008 by Steven DiMartino

If you like cold weather, you are going to love this coming weekend! If you don’t, well stay indoors.
The Arctic air mass that we’ve been waiting for since late October will be arriving in the forecast area this weekend with temperatures averaging 10 to 16 degrees below normal for afternoon highs. Friday and Saturday [...]

Cold Turkey, But Not As Cold As Today

November 22nd, 2008 by Steven DiMartino

The pattern is going into a state of significant amplification throughout much of North America and Northern Hemisphere. I want to state right off the bat that I agree with HPC that the ECMWF solution from 00Z is a strong outlier so I threw the model out. Interestingly, the ECMWF this fall has not been [...]
