The HRRR and RAP Models were both upgraded today. Many changes to the internal physics where introduced which should improve the forecast accuracy of both models.
More details can be found here in a technical notice from NCEP.

The HRRR model was increased to 18 hours on the Wright-Weather site.
The RAP model will be increased to 21 hours from 18 hours later this week.

The real-time Lightning data feed, which has been having communications issues recently has been fixed.
All real-time lightning data is flowing and expect no additional real-time lightning strike data issues.
Real Time Lightning Plots can be found under the “Observed’ menu item and under Single Site Radar and Mosaic Radar menus.
The Heat Index and Relative Humidity were added to the HRRR model.
Also the HRRR model is scheduled for an upgrade later this month. A separate announcement will be made when the upgrade is completed.
NCEP has significantly upgraded the HWRF this year in time for the heart of the 2016 tropical season.
I have updated the code to process the new higher resolution HWRF data which is double the resolution of the older model output.
Invest 97L is now available along with other systems being monitored in the Atlantic and Pacific Oceans.
Check the Tropical Products menu on the home page, under “Site Navigation” for the name of the tropical system with word HWRF appended to it.
