This is view from space after the storm moved out on. The storm was from December 16-20th. Everyone was hit hard except the lower Delmarva.

 We had the prefect set-up for this storm with the Classic HIGH pressure over Southern Canada bringing in a few pool of Arctic Air and the LOW down south loading up on Gulf of Mexico moisture.

 

The Formation of the December 2009 Mega Snowstorm

 

On December 16, 2009, meteorologists identified a storm forming in the Gulf of Mexico. It produced record rainfall in regions of Texas and had the potential to strengthen as it moved through Georgia and Florida and further north. 

 

Weather models accurately predicted that this storm would meet with cold air while retaining its heavy precipitation. The GFS and Euro did very well with this storm and the NAM had the precip dead on about 24-36 hrs before the storm.

 

By the afternoon of December 19, the large, low pressure region had moved off the East coast, intensifying and bringing heavy snow to the major Mid-Atlantic cities.  Blizzard warnings were issued inWashington, D.C.Baltimore, and Long Island. As the storm moved northward along the East coast, at one point it measured 500 miles (800 km) across 14 states. The storm produced whiteout conditions and dumped about 16–20 inches of snow in major cities along the Eastern seaboard.

The same type of weather we have been experiencing recently here in Dec 2012 is what we experienced in Dec 2009.

Lets not forget the March 1st cold snowstorm earlier in 2009, yes it was not as widespread but for us here along the coast it was a good 12 incher. This system ocurred after a mild February.

Remember that year in late 2009 we had a few tropical systems dump on us, we had a crazy hybrid in September.

98 yanks, I only have videos of the storms after Christmas that year, as I was given a camera for Christmas after the Dec 19th event.

I also remember snow was on the ground for Christmas but it melted that day and it was gone as warm air set up.
