As shown in the attached screenshots, the HRRR model on the left does not show the wind streamlines, but when I switch to the NAM, the streamlines are present. They also are present on the GFS, though I did not attach a screen shot for that model. I know the HRRR used to show them, but then they disappeared on a recent update.
Welcome to the forum @jonaroberts.
Thanks for the bug report. They are indeed broken. I’ve just put it on my list to fix in the next release which should be out later this week.
Thanks, Duane. Appreciate it.
