TXweatherman well in this case I only go out as far as 10 days since thats as far out as the CMC goes , just crazy how 2 models can have such different solutions, wonder what each model is picking up on to have such a different outcome

500mb pattern is very different. CMC has an Alaska to North Pole ridge. GFS has a stout Low and very low heights in the GOA.

Volatility is going to continue within the guidance for the next couple of weeks. A lot of atmospheric changes are happening. MJO finally moving out of the COD into colder phase 7, tropical disturbances development in the W PAC after being virtually dead all summer and a Strat Warning event developing within the next 10 days. Keep an eye on the Christmas Holiday period. Into the New Year.

12z GFS tries to have snow in Oklahoma & parts of Northern Texas, but there is too much dryness.

On the Temperature, you can see the DFW Heat Island

12z GEFS has a large percentage of Ensemble Members showing more snow in the Southern Plains starting at +318 hours, which is unusual.

During the winter, what happens up there usually influences our weather down here.

I don't trust it either, but more of the Ensembles are showing snow for Texas compared to the last several runs, they are noticing the StratWarm
