Forecast Laboratory 2015 helps you master your severe weather forecasting skills with hundreds of actual spring days between 2010 and 2014. This is an expanded, updated, and reworked version of our popular 2006 forecasting simulator. It contains 68,000 charts for 455 spring and early summer days spanning 2010 to 2014, including big outbreaks, ordinary scenarios, and null events. You can either choose a date in Case Study mode or try your hand at forecasting a random date, with no clue provided what the date is until the very end. The moment the date is revealed is often quite a shock!

When you start in Chase Mode, a random day appears on your screen. You are presented with the full spectrum of 1200 UTC (morning) charts, including mesoscale surface maps, soundings, NCEP upper air plots, radar, and satellite imagery. There are also SPC diagnostic products, and, if you wish, a chart of SPC risk areas, watches, and warnings. You can send any chart to your printer to do a hand analysis. After you've perused the charts, you need to pick a base city for your chasemobile from one of 12 major cities. Then start it on its way towards the target!
When you're ready, advance hour by hour and watch all the charts change. Your target might shift. Don't forget to adjust the position of the chasemobile! It can be a tricky decision, because you can't move it more than 50 miles each hour. As severe weather unfolds, you'll see reports stream in from locations close to your chasemobile. A karma rating keeps track of how good or disappointing your chase is doing, comparing your own success and what's going on just over the horizon. At 0200 UTC (9 pm CDT) the game ends and your chase is scored. The date is revealed and a summary of any of the day's events is presented. How did you do? Fortunately, you can try again! There are hundreds of other scenarios available!
Want to practice your skills running a spotter network, an emergency management agency, or a base weather station? Site mode will allow you to keep tabs on the severe weather threat at a single, fixed location. Site mode operates similar to Chase Mode by presenting a random, anonymous day on your screen. You assess the threat of severe weather using the full spectrum of 1200 UTC (morning) charts, including mesoscale surface maps, soundings, NCEP upper air plots, radar, SPC products, and satellite imagery.
As you advance forward through the day, you will be expected to issue a severe watch or tornado watch with as much leadtime as possible. But don't issue it too early, because the patterns may change and you could be stuck with a false alarm. Once severe weather develops, you may also issue a warning for your location, which will be good for any severe weather occurrence that takes place within 50 miles.
Case history mode (non-gaming)
For those that just want to browse the charts without running a game, case history mode allows you to do this. No dates are hidden and you may freely browse through the charts and call up any chart for any date between 2010 and 2014.
