Product Name Brief Description Operational Date
HPC Probabilistic Winter Precipitation Guidance The Probabilistic Winter Precipitation Forecasts (PWPF) show the probability of various amounts of snow or freezing rain. They are based on the deterministic Hydrometeorological Prediction Center (HPC) Winter Weather Desk (WWD) accumulation forecasts, but are generated automatically using an ensemble of model forecasts along with the WWD forecasts 2012-03-13 
Digital Wind and Wave Forecasts on Inland Lakes and Reservoirs Wind and wave digital forecasts on inland lakes and reservoirs in text and graphical forecasts on the WFO web page. Wind and wave forecasts created within the GFE using the NOAA/GLERL wind/wave model.WInd wave forecasts for the lakes are produced using forecaster derived data. 2012-03-01 
National Snowfall Analysis The National Weather Service (NWS) collects snowfall data from NWS Cooperative Observers (COOP) and from Community Collaborative Rain Hail and Snow Network (CoCoRaHS) observers to support its forecast and warning operations. Individual Weather Forecast Offices (WFOs) typically provide snowfall collectives in text (and occasionally in graphical) format for their areas of responsibility. This service provides unified snowfall analysis estimates for the continental US. The service includes an interactive web based map to display the snowfall analysis, as well as the ability to download the information in shape file format 2011-11-15 
Real-Time Mesoscale Analysis (RTMA) The National Weather Service (NWS) weather forecast offices (WFOs) produce and send digital forecasts to various users. These forecasts of hydrometeorological variables, such as temperature and precipitation, contribute to the generation of the NWS National Digital Forecast Database (NDFD). The Real-Time Mesoscale Analysis (RTMA) is a gridded analysis of the hydrometeorological variables that matches the NDFD spatial resolution. Products from this analysis are generated hourly, disseminated to NWS field offices and National Centers, and available for external users. The RTMA is the first component of the NWS Analysis of Record (AOR) project. RTMA product generation for the CONUS region includes the following products: surface temperature, surface dew point, wind speed and direction, and cloud and precipitation amount products, and u and v wind components. The product set generated for RTMA Alaska, Hawaii, Guam and Puerto Rico contain the same parameters as CONUS regions except for the cloud amount and precipitation products. Analyses for the Guam domain are available at three hour intervals. An analysis uncertainty product is generated for all RTMA products except the cloud and precipitation products, and u and v wind components. 2011-10-04 
Web-Enabled International Flight Folder Documentation Program (WebIFFDP) Website distribution/access to International Flight Folders currently available through facsimile-based system. This is a website maintained by AWC with global aviation weather information. It is intended for use by airline operators for international flights originating or ending in the United States. As a contracting state of the International Civil Aviation Organization (ICAO), the United States is obligated to provide flight documentation services to the international aviation community. On October 1, 1998, in accordance with Chapter nine of Annex 3 to the Convention on Civil Aviation, the Aviation Weather Center (AWC) began providing the required meteorological information to Airline operators and flight crew members for the purposes of dispatch planning, pre-flight briefing, and en-route guidance. The information for the International Flight Folder Documentation Program (IFFDP) is currently transferred via a facsimile service. Web-enabled International Flight Folder Documentation Program (WebIFFDP), is a replacement of the current facsimile-based International Flight Folder Documentation Program (IFFDP). WebIFFDP is available for use 24 hours a day, 7 days a week. 2011-09-12 
Fire Weather OutlookElements in National Digital Forecast Database (NDFD) Two digital data elements in the NDFD, and associated web imagery, forecasting fire weather conditions, originating from the Storm Prediction Center: - Fire Weather Outlook Critical/Extremely Critical Areas (Days 1-7) - Fire Weather Outlook Critical Areas for Dry Thunderstorms (Days 1-3) 2011-07-15 
HPC 6hr Interval Quantitative Precip Forecast for days 4 and 5 This Product provide QPF forecasts for days 4 and 5 in six hour increments. HPC forecasters prepare forecasts for 6hr periods out three days. In addition HPC forecasters prepare a 48hr forecast for days 4 and 5. Several RGCs have requested that HPC provide the day 4 and 5 forecasts in six hour increments rather than one 48 hr increment.This will augment the current 48 hr forecast prepared by HPC. 2011-07-06 
Bulleted Coastal/Lakeshore Hazard Message (CFW) and Marine Weather Message (MWW) This displays the CFW and MWW in a bullet style format 2011-06-02 
Bulleted Winter Storm (WSW),Non-Precipitation (NPW), and FireWeather(RFW) Statements During long duration winter storm, non-precipitation and fire events affecting multiple forecast zones, WSW, NPW and RFW weather watch, warning, advisory products (WWA) can become very long and time consuming for forecasters to produce. The length of the product can make it difficult for users to quickly scan multiple forecast zones for vital storm information. Since 2009, starting with WFO Reno (which developed the software template) and expanding each year to over 100 WFOs in 2011, an experimental bulleted template for descriptive text in place of paragraphs has been used to produce long duration WSW, NPW and RFW WWA products within the AWIPS Graphical Hazards Generator (GHG) software. As of AWIPS Build 9.3 now being implemented in the field, GHG contains a baseline operational version of the software. 2011-05-24 
Storm Based (Polygon) Special Weather Statements ER Threat based polygon warnings, or storm based warnings were implemented nationally in 2008 and essential to effectively warn for severe weather and flash floods. SB warnings show the specific meteorological threat area and are not restricted to geopolitical boundaries. By focusing on the true threat area, polygons help improve NWS warning accuracy and quality. ER initiated an experimental Polygon Storm Based Special Weather Statements (SBS) at Weather Forecast Offices (WFO) Blacksburg, VA and State College, PA in 2009 to promote increased accuracy of alerting the public to significant weather events. The SBS methodology allows the forecaster the opportunity to be spatially specific, eliminating large areas needlessly alerted when compared to issuing a county based SBS. Based on positive feedback from partners and users, the SBS has been transitioned to an official product for all ER WFOs. The Guidelines for SBS issuance are included in ER supplement 05-2010 Special Weather Statements. 2011-05-13 
Mountain Pass Forecast The Mountain Pass Forecast allows customers to check the forecast for significant highway passes for the next three days. Passes were chosen for this product based upon the frequency of calls to the WFO concerning weather at the pass and potential for impacts to travelers and commerce.The forecast consists of a text product that can be accessed via a web page 2011-05-12
