The SPoRT modeling group has been producing a 3 km LIS over the SE CONUS and adjacent areas stretching into the Great Lakes and Great Plains for about two years now. These data have been made available to collaborative NWS offices through the Southern Region LDM during that time. However, imagery from the 3 km LIS runs are now being made available through the SPoRT web page.
From the SPoRT home page, mouse over the “Core Projects” menu and select the Modeling link. In the page that opens select real-time AL data or real-time SEUS data in the Real-time Land Information System menu box near the top right. For convenience, here is a more direct link to the SE CONUS graphics… http://weather.msfc.nasa.gov/sport/case_studies/lis_SEUS.html
