2010 as an enhancement to the main website. On April 15, 2010, WGRZ debuted new weather graphics (utilizing WSI TruVu MAX for standard graphics), and upgraded radar and weather alert systems (utilizing WSI TruVu TITAN for Live Precision Doppler 2, and WSI TruVu Alert for weather alerts). All radar and graphics systems were upgraded to full high definition (it was the first Buffalo station to have a HD weather graphics system; WKBW followed in November 2010, followed by WIVB in February 2012) and provide enhanced capabilities compared to previous systems used. On May 3, 2010, "Precision Doppler 2" introduced 3D storm-tracking capability, as well as a real-time lightning indicator (WIVB had earlier upgraded its radar to include these capabilities in 2007); it also debuted a new weather crawl system called "Storm Team 2 Alert", with enhanced features such as the ability to display both county maps and doppler radar with any warnings that are issued. The Storm Team 2 Weather app was introduced in July 2010 providing new mobile capabilities. In January 2014, WGRZ debuted their new digital subchannel called Storm Team 2 WeatherNation TV. The new channel combines local forecasting from WGRZ's in-house meteorologists with national forecasts provided by the staff of WeatherNation TV. This has since been replaced by the Justice Network.

This new set features a view of multiple Buffalo landmarks, including Buffalo City Hall, Fountain Plaza, the new Avant Building, the new Robert H. Jackson United States Federal Courthouse, among others. It will complement the existing weather set indoors and makes WGRZ the second station in the Buffalo market (after WKBW-TV) to have a dedicated outdoor weather set. Ratings Aside from a brief period in the 1970s when lead anchor Ron Hunter led WGR-TV's newscasts to the top of the Nielsen ratings, WGRZ was historically the third-place station in the Buffalo market through most of its first four decades on the air. It trailed usual market leader WKBW-TV and heritage station WBEN-TV, later WIVB-TV. WGRZ, WIVB-TV and WKBW-TV have been among the highest-rated television stations in the country and all three are fiercely competitive in the market's local ratings. Both WGRZ and WIVB-TV benefited from WKBW-TV's decline in the late 1990s; WGRZ had the further advantage of investment from Gannett, a major
