Tonights 00z model runs, stopped them at day 10 (hour 240) CMC on the left and GFS on the right, talk about some crazy model disagreement

That’s usually what happens when it’s 10+ days out

[Stratton20]

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

[Iceresistance]

Stratton20 There is a crazy amount of snow 10 days out on the 0z CMC, mostly along I-40 in Oklahoma (Center of the snowbands)

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

We could careless if Northern tx gets snow or not lol we are more focused down here on the houston area

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.

Well well well, that may happen, there is model consistency for a Stratwarm, Joe B is showing the difference between now & 10 days out

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
