Product Name Brief Description Submitter Date Entered
Experimental Precipitation Potential Index (PPI) in the NDFD The Precipitation Potential Index forecast is now available as a new element in NDFD experimentally. The Precipitation Potential Index (PPI) is used by Weather Forecast Offices to derive 12-hour Probability of Precipitation (PoP12) forecasts and provides detail on precipitation timing at up to hourly resolution Providing PPI via NDFD enables users to make near-term decisions based on finer temporal resolution precipitation information than 12-hour Probability of Precipitation Andy Horvitz 2015-07-24
Experimental NDFD Full Resolution XML Web Service The National Digital Forecast Database (NDFD) contains a seamless mosaic of digital weather forecasts from National Weather Service (NWS) field offices and the National Centers for Environmental Prediction (NCEP). Full resolution data from NDFD web services will be made available experimentally in order to be consistent with the resolution of data provided in Gridded Binary Data Edition 2 (GRIB2) via file transfer protocol (ftp) or hypertext transfer protocol (http), and that of graphical images produced by the NDFD Map Viewer.

Experimental International Arrival and Departure GATE Forecasts These web-based International Departure Gate Forecast (IDGF) and International Arrival Fix (IAF) forecasts provide categorical convective guidance for specific locations in the National Airspace System (NAS) allowing for more accurate air traffic management. These forecasts will be a collaborative effort between the NOAA/NWS Center Weather Service Units (CWSU) located at the FAA Air Route Traffic Control Centers in Nashua NH (Boston), Ronkonkoma NY (New York) and Leesburg VA (Washington).The purpose of this experimental web page is to provide the Federal Aviation Administration (FAA) and the airlines with expanded weather planning information.This expanded information begins to address a gap in the NWS convective product suite and the Terminal Aerodrome Forecast (TAF). Specific forecast products are not available that forecast convective weather at aeronautical arrival and departure fixes (known as gates). Thunderstorm impact at or near these gates has a significant impact on the flow of aircraft through the NAS causing delays. This will allow critical partners and customers to make more informed decisions regarding the air traffic flow through the NAS. Scott Reynolds 2015-08-28
Experimental Weeks 3-4 Temperature Outlook The National Weather Service, Climate Prediction Center delivers real-time products and information in order to monitor and predict climate variations and their potential associated impacts on timescales from weeks to about 1 year. The objective is to promote effective management of climate risk and a climate-resilient society. Currently, the Climate Prediction Center issues temperature outlooks for the Week-2 and 1-month outlook time periods. No current products exist for the intermediate timescale (i.e. Week 3-4) between these two forecast time horizons. The initial release of the experimental Week 3-4 Temperature Outlook will consist of two components. These are (1) a temperature outlook map targeting the combined Week 3-4 outlook, and (2) prognostic map discussion (PMD) text explaining the rationale for the forecast. Jon Gottschalck 2015-08-28

Experimental Gulf Stream Forecast The Gulf Stream Forecast is a 3 hourly forecast for areas along the Gulf Stream as output from the NWPS model from the WFO Miami Forecast Office. The graphic display shows the Gulf Stream current, significant wave height, wind speed, and peak wave period and direction in graphical formats. There are 4 separate geographical areas, and all the graphs can be stepped in time or looped on the webpage. Melinda Bailey 2015-09-11
Experimental Lake Effect Snow Warning Polygons The experimental Lake Effect Snow Warning (LES) polygon areas delineate the locations of highest impact of the LES. As the lake effect shifts, polygon areas will change spatially and temporally to best delineate the areas of highest impact over the course of the LES event (for example, snowfall rate, blizzard-like conditions, total snowfall). Issuance of the product would be based upon forecaster confidence of reaching LES Warning criteria: 7 inches or more in 12 hours, or 9 inches or more in 24 hours. Jason Franklin 2015-09-17

Experimental Days 3-7 Winter Storm Threat The purpose of the Experimental Days 3-7 Winter Storm Threat product is to graphically display location and level of winter storm threats in the extended portion of the forecast 3 to 7 days in the future. This threat level combines forecaster confidence and potential impact. Rick Watling 2015-11-23
Prototype Texas Regional Rainfall Webpage The Texas Regional Rainfall webpage will display the most current quantitative precipitation estimates (QPE) produced by the Advanced Hydrologic Prediction Service (AHPS). Four maps containing QPE for durations of 24-hour, 48-hour, 72-hour, and weekly will be available each day for a region of Texas containing the County Warning Areas of the National Weather Service offices in Brownsville, Corpus Christi, Austin/San Antonio, and Houston/Galveston. There will be a built-in archive function on the webpage that will allow the user to quickly obtain QPE maps for past dates. Melinda Bailey 2015-12-15
Experimental PEAC Monthly Climate Summary and Forecast for the Federated States of Micronesia The Pacific ENSO Applications Climate (PEAC) Center was established in August 1994 as a multi-institutional partnership, to conduct research and produce information products on climate variability related to the El Nio - Southern Oscillation (ENSO) climate cycle in the U.S.-Affiliated Pacific Islands (USAPI). To this end the PEAC Center provides rainfall, sea level, general and island/island grouping specific forecasts, and a tropical outlook to the USAPI on a monthly and quarterly basis by means of a printed bulletin (see http://www.weather.gov/peac/update). The dissemination of these summaries and forecasts need wider distribution to the climate community. Therefore, placing these forecasts into AWIPS will allow not only wider distribution, but an easily accessible archive. Providing climate data is part of the NWSs mission and connected to all six of our primary goals. By making these forecasts easily available, the NWS is enhancing climate services to help communities, businesses, and governments understand and adapt to climate-related risks. The product proposed, issued monthly, is a seasonal climate summary and forecast of rainfall and sea level for the four states of the Federated States of Micronesia: Yap, Chuuk, Pohnpei and Kosrae. Individual sections for each island will include a summary of climate conditions observed on the island along with observed rainfall and sea level values. The forecast for each section/state will include a forecast summary of expected climate conditions over the next season, a probabilistic seasonal rainfall forecast by season for the next 12 months, a long range rainfall forecast in percent of total rainfall, and a deterministic sea level forecast.

Providing climate data is part of the NWSs mission and connected to all six of our primary goals. By making these summaries easily available, the NWS is enhancing climate services to help communities, businesses, and governments understand and adapt to climate-related risks. The product proposed, issued quarterly, is a regional climate summary of rainfall, sea level and tropical cyclone activity for the USAPI. Individual sections will include a general summary of climate conditions across the Pacific Ocean, a discussion of the past season, a brief discussion of the southern oscillation index, tropical cyclone activity and broad forecast, reported sea level data, ENSO alert system status, and a general seasonal forecast of ENSO.

Experimental Water Information Interface Webpage Effective on or about Tuesday, June 14th, 2016, the National Centers for Environmental Prediction (NCEP) will begin operationally running version 1.0 of the National Water Model (NWM). The NWM is an hourly uncoupled hydrologic analysis and forecast system that will provide streamflow for 2.7 million river reaches and other hydrologic information on 1km and 250m grids. The NWM provides the NWS with a multi-scale, parallelized, process-based water cycle modeling capability. Upon initial implementation, the NWM system will provide multiple country-wide hydrologic analysis products and forecast output across a range of forecast lead times. These will be combined with other data from NOAA to provide the Nation with comprehensive information on a range of water-related concerns such as snowpack, soil moisture, and potential areas of flooding.Version 1.0 of the NWM will provide a capable and solid foundation that will support year-over-year growth in operational hydrologic forecasting capability. Goals for this initial implementation include: 1) Provide forecast streamflow guidance for underserved locations 2) Produce spatially continuous national estimates of hydrologic states (soil moisture, snow pack, etc.) 3) Seamlessly interface real-time hydrologic products into an advanced geospatial intelligence framework 4) Provide a modeling architecture that permits rapid infusion of new data, science and technology Dan Roman 2016-03-16
Enhancement to the Operational Twitter SDD Update Service Description Document for Twitter to indicate that NWS may provide tweets of short fused watches/warnings/advisories. Current description of our service indicates that NWS will only provide tweets with long fused alerts. Also need to indicate that NWS may provide content-specific feeds in addition to office-oriented feeds. Content specific feeds better meet the needs of our national partners who arent focused on the area of only one particular office. Wendy Levine 2016-05-10
