Fwd: Good Results on a Frontal Timing

    Posting on behalf of Rob Cox, the SOO at CYS.    His attempt to post didn't work for some reason, but he has an excellent example of FV3GFS improvement with a surge of cold air into southeast WY and is asking if others have seen similar handling of cold surges.

Hello,

The 09/00Z run of the FV3 did pretty well on the timing of the secondary surge of an Arctic Front. This surge pushed through southeast Wyoming on Friday, February 9, 2018 during the afternoon. The GFS/HRRR/NAM were about 3hrs too slow. We have attached some imagery of the MSLP/Temp from the GFS/FV3 comparisons page. We have also attached imagery from the GFE obs database from Cheyenne. Has anyone else noticed that the FV3 is doing well on the timing of the Arctic Fronts? Please share any feedback.

Thanks,

Rob
