Product Name Brief Description Operational Date
Enhancement to the National Snow Analysis: NOHRC Snow Model and Forecast Products Expansion The NOHRSC is expanding the spatial domain of its gridded snow model into Canada to include the Great Lakes drainage area. Additionally, the NOHRSC is executing the model in a 72-hour forecast mode. The Rapid Refresh (RR) model forces the first 18 forecast hours and the North American Mesoscale (NAM) model forces the remaining 54 forecast hours. 2012-10-27 
Area Fire Weather Forecast Matrix (AFW) for WFO GSP Land management agencies in Georgia, North Carolina and South Carolina have expressed a need for easily accessible tabular forecast data similar to the Point Fire Weather Forecast Matrix (PFW), except that it encompass an entire fire weather zone instead of just a point. The requirement is for something similar to the existing Area Forecast Matrix (AFM), but with fire weather/smoke management parameters included. It would be tailored to facilitate fire behavior applications in the planning stage by land managers. An area fire weather matrix would satisfy this need well because it would allow agency specialists to quickly run sample fire behavior models for planning purposes for random areas outside of PFW forecast points. The experimental product will be called the Area Fire Weather Forecast Matrix (AFW) and would be generated routinely for all 56 zones in the WFO Greenville-Spartanburg (GSP) county warning area. (CWA) : The experimental AFW is produced by running a modified AFM formatter that uses the local digital forecast data base (DFD). The product will be generated via a GFE automation script every time grids are published by a forecaster. A script will also post the AFW to the WFO GSP website. No additional grids or forecaster intervention will be required. 2012-10-27 
SPC Enhanced Resolution Thunderstorm Outlook The Storm Prediction Center (SPC) is the National Weather Service’s (NWS)center of expertise for forecasting convection, including economically-disruptive weather events such as tornadoes, large hail, damaging winds and heavy rainfall. Included within the SPC Severe Weather (Convective) Outlook (SWO) for the CONUS is a forecast for a 10% or greater probability of thunderstorms. Since these thunderstorm forecasts cover a 24 hour period with only the 10% probability contour, they provide little in the way of temporal or spatial resolution. The SPC Thunderstorm Outlook adds greater temporal and spatial resolution by depicting the expected areal coverage and probabilities for thunderstorms in 4 or 8 hour time periods. A 40% probability means that given similar environmental conditions, a thunderstorm would be observed at any one location (in either a county or city) within the 40% thunderstorm probability area four times out of ten, or 40% of the time. The greater temporal and spatial resolution of the SPC Thunderstorm Outlook will aid both NWS forecasters and NWS Partners in time-sensitive decisions related to thunderstorms, and ultimately provide greater safety for the United States public. 2012-09-26 
National Ceiling and Visibility (NCV) Analysis Product The NCV product is a frequently updated representation of current ceiling and visibility conditions derived from METAR (ASOS) stations and GOES satellite information. The products ceiling and visibility fields are derived through nearest neighbor interpolation of METAR data. This interpolation process, in effect, stretches limited-area METAR observations across the broader domain between stations while an accompanying process accounts for terrain effects on ceiling height. The resulting field helps to visualize the likely conditions at range from METARS. 2012-07-24 
UltraViolet Radiation Grids in the NDGD The following gridded data is now available in the National Digital Guidance Database (NDGD): Ultraviolet Index, Daily Maximum Ultraviolet Index and Downward Short Wave Radiation Flux. These grids will be derived automatically from the 1200 UTC model run of the Global Forecast System (GFS) for the Conterminous United States (CONUS). The Ultraviolet Index grids will be available for each daylight hour out to 48 hours, while the Daily Maximum Ultraviolet Index grids will be available once per day out to 120 hours and the Downward Short Wave Radiation Flux grids will be available for every third daylight hour out to 120 hours 2012-07-10 
Approach and Departure Gate Forecasts for Convection (TRACON) TRACON Approach and Departure Gate Forecasts will complement the Collaborative Convection Forecast product by providing greater detail of convective occurrence. TRACON Approach and Departure Gate Forecasts will be developed for the 8 TRACONs New York, Atlanta,Houston, Dallas Fort Worth, Miami, Denver and Chicago. TRACON Approach and Departure Gate Forecasts will provide ATCSCC, ARTCC, TMU and TRACON a graphical product for planning air traffic flow safely and efficiently around convection into and out of the TRACON area. The graphic will provide easy to interpret color-coded convective forecasts and allow partners to make more informed decisions regarding the air traffic flow through the NAS. 2012-05-22 
Extended Convective Forecast Product (ECFP) Automated probabilistic 24 hour thunderstorm outlook based on SREF Calibrated thunder guidance. This automated graphical forecast is created from the Short Range Ensemble Forecast (SREF) Calibrated Thunderstorm output. Contours are drawn at 40, 60, and 80% probability of “thunderstorm” (not convection) using CCFP-like shading. Hashed areas represent 40-59% probability, solid lined areas represent 60-79% probability, and solid blue filled areas represent greater than 80% probability. The automated graphic uses the 09Z initialization of the SREF valid for 18Z-00Z the next day 2012-04-16 
Redesign NWS Web Services Via Wireless Technologies This product is a redesign of its existing mobile web page, The goal of the redesign is to update the look, feel, and functionality of NWS mobile web presence in order to better take advantage of the capabilities. 2012-04-01 
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
