Other updates and additions:

  • Renamed WW3 to GFS-WAVE.

  • Replaced 4-panel sim_radar RAP with HRRR and extended the forecast hours from F21 to F48.
  • Upgraded HAniS package to improve Pinch/Zoom capability on mobile devices, and to prevent scrolling on OnMouseEnter events.
  • Improved precipitation visualization for SREF so that the precip mean is represented by color fills to be consistent with the rest of models.
  • Improved helicity color fills for all models.
  • Improved G-ESTOFS color fills for wave products.
  • Improved domain names for Observation and Analyses data.
  • Decluttered SREF contour labels for the spread of CAPE and CINS.

MAG 3.18.7 - March 2021

  • In conjunction with the HREFv3/HiResWv8 model upgrade, HiresW-NMMB is replaced by HRW-FV3.
  • With the HREF upgrade, the probability of maximum updraft hlcy with a threshold of greater than 100 m^2/s^2 is no longer computed. Probability of maximum updraft hlcy with thresholds greater than 75m^2/s^2. and 150 m^2/s^2 are added.

MAG 3.18.5 - October 2020

  • Extend RAP forecast hours from F39 to F51 for 03/09/15/21Z cycles.
  • Extend HRRR forecast hours from F36 to F48 for 00/06/12/18Z cycles.

MAG 3.18.4 - October 2020

  • In conjunction with the G-ESTOFS model upgrade, MAG will utilize the unified gempak files for “conus”, “hawaii”, and “alaska” to create images for all valid domains.
  • With the G-ESTOFS model upgrade, the coordinate of native grid is changed to cut the interpolation at the 180th meridian. This upgrade will hence limit the data presentation east of 180 for Alaska domain for all the estofs images.

MAG 3.18.3 - September 2020

  • Extend NBM forecast hours from Fhr226 to Fhr264 for precip_p06 and precip_ptot for the conus and namer domain in conjunction with NBM v4.0 upgrade.

MAG 3.18.2 - September 2020

  • Include the 30 ensemble members for GEFS-SPAG in conjunction with the GEFS v12 upgrade.
  • GEFS-MEAN-SPRD products will reflect the GEFS v12 upgrade.
  • GEFS storm-tracks for Alaska domain will include the 30 ensemble members and the control run in conjunction with GEFS v12 upgrade.
  • GEFS probability storm tracks for Alaska domain are updated in conjunction with increased number of ensemble members with GEFS v12 upgrade.

MAG 3.18.0 - April 2020

  • Consolidated the Wave Watch III Model (WW3), the Wave Watch III Regional Eastern North Pacific Model (WW3-ENP), and the Wave Watch III Regional Western North Atlantic Model (WW3-WNA) into WW3.
  • Added the following domains to Storm Tracks GFS:
    • Continental United States (CONUS)

    • HRW-ARW2
  • Removed mean sea level pressure and thickness contours from simulated radar products for the following models:
    • HRRR
    • FIREWX
    • HRW-NMMB
    • HRW-ARW
    • HRW-ARW2
  • Removed dashed lines from GFS and NAM 500_vort_ht, and use color fills to plot vorticity between 12-16*10-5/sec.

Other updates and additions:

  • Fixed pinch zoom for images so that the zoom centre spot is at the midpoint of the two fingers.
  • When using time range selection, auto-fill the first and last forecast hours with default time steps in the data.
  • Add a message in Storm-Tracks for when the user selects a model not valid for that cycle: "<Model> is not available for <cycle>UTC cycle, Choose a cycle from the list above."
  • Fixed a bug with sub-hourly products Time Range Selection, where clicking on the current starting or ending forecast hour link did not properly set a new starting or ending forecast hour.
