This is why Meteorologists get a forecast wrong? My Complex Thanksgiving Forecasts


OMG Confusing Stuff. Models are having a very tough time for next week’s storm. Big question is where does the Upper level low over the Southern California goes, the Split Jet Stream where does it converge, and The Northern Low Pressure/Short Wave where does this piece of energy goes and how fast does it move, the NAO, PNA Forecasts. Everything is all over. My confidence of a storm is quite high about 95%. The placement of this storm is extremely low about 5% or less. The precipitation type for key forecast points Bos, NYC, Buf, Pit, Phi, Ext is extremely low for most about 30% Confidence or less. The Artic Plunge placement is low about 30%. So I want to ask you all, can we get the computer forecast model to agree on something to make forecasters job a bit easier.

 

Details….

 

Current Conditions….

Low pressure over the  Southern California, High Pressure over Nebraska South Dakota, High Pressure off the cost of Boston, and low pressure North of North Dakota and Low Pressure North of Idaho.



GFS OZ 11/21/13 for 0HR



It is the orange circled events that we have to watch closely on. The green are the projected current tracks of this system.

 

If it takes the further Eastward Track that ends near Albany, NY it will be a major Snow Storm Followed by A Flood of Artic Air. It may even be a Blue Northern where extreme cold air will come in for the Great Lakes and Mid-West for Thanksgiving.

If it takes the track off the cost of George South Carolina it will be just a rain maker and the Cold air retreats and Sunny for Thanksgiving in the Northeast.

 

I am not going to past the forecast models just yet as no one has the right idea, if they do they must be gifted.
