| Probabilistic Quantitative Precipitation Forecasts | NOAA's Strategic Plan states that we are to "Improve the reliability, lead-time, and effectiveness of weather and water information and services that predict changes in environmental conditions." To support that effort, The National Weather Service Strategic Plan for 2005 to 2010: Working Together to Save Lives, establishes a mission goal to develop new capabilities and move into a new direction of forecasts... and expand beyond traditional weather and water products.
In response to the NOAA and NWS goals, the Weather Forecast Office in Tulsa, Oklahoma (TSA) has developed a method to provide probabilistic quantitative precipitation forecasts on a routine basis, in the form of probability of exceedance (POE) forecasts. This method will be used at several Weather Service Forecast Offices (WFOs) in the Southern Region. These POEs will provide our clients and customers with more detailed precipitation forecasts that they can use in their decision-making processes.

| Probability of Exceedence Outlook for Center Probability Distribution (50 percent) | The Climate Prediction Center (CPC) issues a series of thirteen three-month graphical outlooks for the 50 percent probability of exceedence (or center probability distribution) for temperature and precipitation across the contiguous U.S. | PEO_v2.pdf |
| Probability of Freezing Temperatures | The Probability of Freezing Temperatures product will be a graphical display on the internet of the probability (in percent) that overnight low temperatures will fall to freezing or below across the (PDT) County Warning Area (CWA) for the ?tonight? and ?tomorrow night? time periods. It will be updated as necessary, but at a minimum with each major Zone Forecast issuance at 3 pm and 4 am local Pacific time. The product will be issued seasonally in the fall from September 15th until November 30th and in the Spring from March 15th until May 31st. | freeze-prob-pdt-1.pdf |
| Probability of Meeting or Exceeding Specific Temperature Thresholds | The Probability of Meeting or Exceeding Specific Temperature Thresholds (e.g. Freezing or 100 degrees) is a graphical display on the Internet of the probability (in percent) that temperatures will either rise above or fall below the desired threshold in a given county Warning Area (CWA) for the Day 1 and Day 2 forecast time periods. It will be updated as necessary, but will be issued at a minimum with each major Zone Forecast package at 3 pm and 4 am local Pacific time. | heatprobpdd.pdt.exp.pdf |
| Real Time US Total Electron Content Vertical and Slant | The US Total Electron Content (US-TEC) product is designed to specify TEC over the Continental US (CONUS) in near real time. The product uses a Kalman Filter data assimilation technique driven by data from ground-based Global Positioning System (GPS) dual frequency receivers. The primary data stream comes from the Maritime and Nationwide Differential GPS (M/NDGPS) real time network of stations operated by the US Coast Guard (USCG). As of Oct 2004 there were about 60 M/NDGPS stations ingested into the model. This number has been gradually increasing and will be augmented by Federal Aviation Administration/Wide Area Augmentation System (FAA/WAAS) data, and stations operated by the Forecast System Laboratory (FSL). This product has evolved from collaboration among Space Environment Center (SEC), National Geodetic Survey (NGS), National Geophysical Data Center (NGDC), and FSL. | USTEC_PDD.pdf |
| Red Flag Potential Index | The Red Flag Potential Index (RFPI) is a graphical product produced by forecasters at WFO Las Vegas (VEF) using GFE/IFPS. Ratings of Red Flag potential (numbers 1 through 4) for the next three days (today, tomorrow and the next day) are calculated using forecasts of relative humidity and prevailing 20-ft, 10-minute average surface wind, along with forecaster knowledge of other factors such as critical fire conditions and the existence of active wildfires. The RFPI is intended to be used as general guidance, primarily for planning purposes. Since the southern half of our forecast area operates an aggressive, proactive prescribed burn program, this product will be issued year-round.

| Regional Flash Flood Guidance Graphics | Flash Flood Guidance (FFG) is the amount of rainfall in a given time period that will produce flooding on small streams. FFG is distributed via AWIPS in text products and lists FFG values for 1-, 3-, 6-, 12-, and 24-hour time periods for each county. The experimental Regional FFG Graphics are Internet web pages that show these FFG values in both graphical and tabular form. These graphic products are for the entire Southern Region (SR) area, the area of responsibility of each SR River Forecast Center (RFC), and each state in SR. In addition to having a state graphic for Texas, graphics of FFG for north, south, and west Texas are available. | RFFGG.pdf |
| Regional/Local Seasonal Forecast | Regional/Local Seasonal Forecasts may be textual or graphical. They typically consist of short-term climate variability forecasts and monitoring data, and meteorological/hydrological interpretation and assessment of societal impact on a web page. These web pages will normally provide educational material to help users understand the forecast methodology and reliability to better aid preparedness and mitigation efforts. The web page will typically assimilate a wide variety of information on short-term climate variability for the forecast area such as links to official NOAA/NWS forecasts and experimental, locally/regionally produced graphical/textual monitoring products. The area covered by the forecast may be a commonly accepted political or geographical location such as a state, county or region, or it may be a uniquely defined in which case the area will be made explicitly clear on a map on the web page.
An example of such a seasonal forecast product suite is the "Florida EL Nino - Southern Oscillation (ENSO) Home Page Featuring:
2002-2003 Experimental Dry Season Forecast for Florida (Valid for period November 1st 2002 through April 30th 2003)" produced by WFO Melbourne, Florida and available on the Internet at: http://www.srh.noaa.gov/mlb/enso/mlbnino.html | SR-6v3.pdf |
| RIDGE ? Radar Integrated Display with Geospatial Elements (National) | NWS is responsible to make its weather, water and climate information widely available to taxpayers using commonly accepted standards and technologies. Currently, the NWS provides weather radar information for all Weather Service Doppler Radars (WSR 88-D) in the United States on the NWS Internet page.
The National Weather Service Southern Region, working in cooperation with North Central Texas Council of Governments, has developed a method to display radar images more efficiently than the previous method. These radar images, call RIDGE (Radar Integrated Display with Geospatial Elements), allows the radar image to be combined with geospatial elements such as topography maps, highways, and county boundaries. This not only produces a better image, but provides additional reference information for users to understand where they are located. RIDGE also adds the ability to overlay polygon warnings issued by the National Weather Service Forecast Offices.

| Rip Current Probability Graphical | The National Weather Services (NWS) Rip Current Probability Graphical product provides a graphical representation of the probabilities of rip currents along area beaches from Pender County, NC south to Georgetown County, SC. This product is issued twice a day. | ERRIPCP.pdf |
| Route Forecast | The Route Forecast (ROFOR) is an alphanumeric product providing a coded route forecast for regularly scheduled flights or upon request for flights that either begin or end in or that have most of the flight path within the National Weather Service's Pac | ROFOR.pdf |
| Sacramento WRF NMM Model Output | The Sacramento WRF_NMM is run locally at the WFO Sacramento and gives hourly output out to 48 hours. The high resolution model is used for operational forecasting and research in Northern California. Model Output graphics, generated by GEMPAK software, are posted for 3 hourly forecast time steps to the WFO Sacramento web page. The fields include geopotential heights, vorticity, temperatures, dew point, relative humidity, wind, vertical velocity, freezing level, precipitation amount and type, sea level pressure, thickness, clouds, precipitable water, convective available potential energy (CAPE), and convective inhibition (CIN). The model would replace existing Workstation Eta output on the website. | SAC_WRF_NMM.pdf |
| Satellite Interpretation Message | SIM is an alphanumeric product providing an interpretation of synoptic weather features, significant weather areas, and various cloud and weather phenomena based upon satellite imagery (visual, infrared, water vapor, etc.). National Weather Service's Pacific Region's Weather Forecast Office (WFO) Honolulu prepares the SIM for a portion of their area of responsibility (AOR). The AORs for WFOs Honolulu vary and depend upon the program (tropical cyclone, aviation, marine, public, and satellite). | SatelliteInterpretationMessage.pdf |
