February Medium/Long Range Thread

Actually more spacing between the trop PV and the southern shortwave on 18z vs 12z.  So the storm is entirely southern forced.  That actually makes it a bit stronger than 12z (no interference from the northern stream), but WAY far from a phase like the Euro/GGEM/Ukie.

I think the GFS just needs a little more time. Let's give it till tomorrow 12z

The GFS is stupid, no matter how much time you give it. What happened to the 15" Richmond was promised at gametime?

Well if you're going by that verification, its jack was off by about 50 miles too far south. Look at the map, and draw your own conclusion.

It's pretty close but that strange elongated TPV with a more north orientation than the Euro is what causes this result. 

Honestly a good reminder how delicate the 500mb evolution can be for the resulting surface translation. Hope its wrong lol
