This experiment will\u00a0explore uses of the\u00a0<a title=\"FLASH\" href=\"https:\/\/inside.nssl.noaa.gov\/flash\/\">FLASH<\/a> suite of flash flood and heavy rainfall products. Participants will be asked to use these products to\u00a0issue experimental flash flood watches and warnings; these\u00a0will include information about the likelihood or uncertainty of a given impact as well as the severity of expected impacts. Novel sources of flash flood observations, including the <a title=\"mPING\" href=\"http:\/\/mping.nssl.noaa.gov\/\">mPING<\/a> mobile application and\u00a0<a title=\"SHAVE\" href=\"http:\/\/www.nssl.noaa.gov\/projects\/shave\/index.php\">SHAVE <\/a>phone calls, will be used to assess the effectiveness of the experimental tools and the experimental watches and warnings.<\/p>\n<p>Two forecasters a week are participating in the experiment, with funding provided by the US Weather Research Program. This week&#8217;s forecasters are Mike Moneypenny (NWS Forecast Office Raleigh NC) and David Ondrejik (NWS Middle Atlantic River Forecast Center). Joining them are guests Chris Legro (NWS Forecast Office Gray ME) and\u00a0Jonathan Brazzell (NWS Forecast Office Lake Charles LA).<\/p>\n<p>Each day of the experiment will begin with a weather briefing from the Flash Flood and Intense Rainfall Experiment at the NCEP Weather Prediction Center in College Park MD. Then forecasters will spend time evaluating the performance of the experimental forecast tools and observations from the previous day&#8217;s shift. Forecasters will then issue flash flood watches and\u00a0warnings as necessary, typically from\u00a03 PM to 8 PM CDT,\u00a0Monday through Thursday. This &#8220;virtual forecast office&#8221; will cover the entire Lower 48.<\/p>\n<p>Today&#8217;s areas of focus can be broadly divided into three main components: the summer monsoon in the Desert Southwest, a complex of strong to severe convection in the middle Mississippi River and Ohio River valleys, and rain across the Middle Atlantic into the Northeast. As I type, our forecasters have already issued an experimental watch and two experimental warnings for afternoon storms in the Southwest (see below for these experimental products overlaid on state\/national boundaries and 6-hr <a title=\"MRMS\" href=\"https:\/\/www.nssl.noaa.gov\/projects\/mrms\/\">MRMS <\/a>rainfall estimates).
