The April 3-4, 1974 Super Outbreak WRF simulation has been added to the case studies page.

A new WRF domain is available! The Region of Interest, or ROI, will be a moveable domain.

Due to a lack of interest and job commitments, the Prairies-WRF has been discontinued

Added Haines Index and Fosberg Fire Index are now available.

The 1-6km Updraft Helicity and Lightning Potential Index are now available.

The WRF model has been updated from 3.4.1.x to 3.7.1.x.

Fire weather parameters (Haines Index and Ventilation Rate) have been turned off for the season. Critical thicknesses, Precipitation Type, Hourly Snowfall, Total Accumulated Snowfall and Snow Depth are now available.

New bufkit profiles have been added: (CWDV) and Armstrong (CWYW).

New to the bufkit profiles page are Lakes Ontario, Erie, Huron and Georgian Bay.

Added Lake Ontario Center Buoy (LO1) bufkit profile.

The August 21, 2011 Goderich Tornado WRF-ARW simulation images and loops are now available.

Goderich Bufkit profile is now available.

Some may have noticed the availability of 80-meter wind images on the model parameter selection page. The 80-meter wind product has been found to be a better indicator of surface wind gust potential during times of strong vertical motion transport. This also applies to the HRRR model.

Mount Forest and Barrie Bufkit profiles are now being produced.

The May 31,1985 Barrie Tornado WRF-ARW simulation images are now available.

Updated image creation software from Grads 2.02 to 2.1+. The result is improved colour ( publication quality) and improved legibility to the wind barbs. The downside: increased file size. In fact, the image files are 3-times larger.

Added Hourly Maximum Parameters; Column Integrated Graupel, Updraft Velocity and Downdraft Velocity.

Added 700-500mb Lapse Rate, 2-5km Updraft Helicity and Simulated Radar VIL products.

Added Bufkit profiles to the site.

Added North Bay to the model forecast sounding table.

Added a smoother and changed the colour scheme of the lapse rate product to enhance legibility.

Changed the Microphysics and PBL Physics schemes of the model from WSM6 and MYN to Thompson and Yonsei (Yonsei University) schemes respectively. The WMS6 was generating an unrealistic forecast of higher precipitation values along the domain borders. Hopefully, this problem is now fixed.
