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.

Results on a Frontal Timing

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
