| IFPS Digital Forecast Page | The IFPS Digital Forecast Page provides an interface for the public to access weather information from the NWS gridded forecast (IFPS) database. The gridded forecast is maintained 24/7 by all 24 Western Region Forecast Offices as part of the national NWS IFPS program. | WRIFPS_pdd.pdf |
| Lightning Potential Index | The Lightning Potential Index (LPI) is a web graphic that displays an index of lightning potential for various parts of the day, with a second day for planning purposes. This product will be issued routinely in the morning and updated as necessary. | LightningPotentialIndex.pdf |
| Low Flow Probabilistic forecast | Currently the National Weather Service (NWS) River Forecast Centers (RFCs) and Weather Field Offices (WFOs) produce a wide variety of river forecasts, which indicate current and future river conditions. The Low Flow Probabilistic Forecasts prepared by the North Central River Forecast Center (NCRFC) will be issued as Web page graphics. The graphics will be for the NCRFCs area of responsibility. They will be issued once a month (after the Climate Prediction Center (CPC) outlooks are released at mid-month). They will cover the three month period after the issuance (for example, graphics released around May 26 will cover June-August period). | NCRFCLowflowProbabilistic.pdf |
| Marine Forecast Matrix | The National Weather Service (NWS) Marine Forecast Matrix (MFM) provides a tabular forecast of wind direction and speed, swell direction and height, wind wave height, significant wave height, cloud cover, probability of precipitation, and areal precipitation coverage. | MFM_PDD.pdf |
| Marine Weather Discussion (MWD) | Plain language free text discussion of computer model trends which focuses on expected wind and sea conditions. The MWD is used as a coordination vehicle among the national centers and coastal Weather Forecast Offices.
| MarineWeatherDiscussion.pdf |
| Marine Weather Message | The Marine Weather Warning (MWW) product is a text bulletin intended to better inform mariners of adverse nonprecipitation conditions. It will also provide consistency of the National Weather Service (NWS) Coastal Weather Forecasts (CWFs), Great Lakes Open Lakes Forecasts (GLFs) and Great Lakes near shore forecasts (NSHs) with other NWS programs (winter weather, hydrologic, nonprecipitation and coastal hazards). | MWW_PDD.pdf |
| Marine Weather Statement (MWS) | Plain language free text discussion of potentially hazardous warning conditions associated with non-severe thunderstorms and/or waterspouts issued on an event driven basis from WFOs. The product is also issued to advise of potential hazardous conditions with wind, waves, visibility, low water levels, hazardous materials spills, volcanic ash, and ice. | MWS.pdf |
| Maximum Tropical Cyclone Wind Speed Probability Table | The WSP shows the probability that maximum 1-minute wind speed forecast for the tropical cyclone will be within one of seven intensity ranges/storm classifications through 72 hours. The maximum 1-minute wind speed forecasts correspond to the wind speed forecasts in the Tropical Cyclone Forecast/Advisories (TCM) product. The probabilities are based on National Hurricane Center (NHC) forecasts from 1988-1997. NHC issues this experimental product for tropical cyclones in the Atlantic and Eastern Pacific basins. This experimental product is also issued for subtropical storms. | TCWindSpeedProbTablePDD1.pdf |
| Meteorological Impact Statement (MIS) | The National Weather Service's (NWS) Meteorological Impact Statement (MIS) is a unscheduled flow control and flight operations planning forecast. The MIS is valid 2-12 hours after issuance time and details weather conditions expected to adversely impact | MIS.pdf |
| Minneapolis TRACON Collaborative Convective Forecast Product | The Minneapolis TRACON forecast product/service will be a collaborative effort by personnel of WFO Minneapolis, CWSU Minneapolis and initially, Northwest
Airlines to produce a forecast of thunderstorm and/or lightning activity within a radius of 100 nautical miles of the center of the Minneapolis airport.

| MULTI-FORMAT FORECAST INFORMATION WEB PAGE | Advances in computer capabilities and web services technologies, as well as scientific advances in National Weather Service (NWS) software, have afforded an opportunity for NWS to create customer-based products and services. | Multi-FormatWebpage.pdf |
| MULTI-FORMAT MARINE FORECAST INFORMATION WEB PAGE | Advances in computer capabilities and web services technologies, as well as scientific advances in National Weather Service (NWS) software, have afforded an opportunity for NWS to create customer-based marine products and services. Information dissemination via the World Wide Web (www) allows customers to obtain higher resolution marine forecast information in a variety of formats on demand. | MarinePointClick0607.pdf |
| Multimedia Weather Briefing | The Multimedia Weather Briefing is an Internet-accessible multimedia file that provides information concerning hazardous weather events within the service area of a Southern Region office. The briefing provides a medium for supporting the planning activities of emergency response partners and customers by conveying (both aurally and visually, in non-technical terms) the forecaster's reasoning and confidence concerning upcoming hazardous weather events. | MultimediaWeatherBriefing.pdf |
| National Air Quality forecast System (AQFS) Ozone (03) forecast | A web-based presentation of gridded forecast O3 guidance originating from the Environmental Modeling Center (EMC) of the National Environmental Prediction (NCEP). The ozone data is displayed for a domain covering the northeast US for 1-hour and 8-hour averages. | AQOzonePDD0707.pdf |
| National Air Quality Forecast System (AQFS) Smoke Forecast Graphic Display | The National Weather Service?s National Air Quality Forecast System (AQFS) Wildland Fire Smoke Forecast (WFSF) Experimental Graphic Display is a web-based presentation of gridded forecast smoke dispersion guidance produced by NOAA's Air Resources Laboratory and Environmental Modeling Center (EMC) of the National Environmental Prediction (NCEP)and using the HYSPLIT dispersion model. The dispersion model is preconfigured to run over the entire country once-a-day using the 0600 UTC NAM meteorological forecast. Hourly average output maps of primary PM2.5 air concentration are produced using the actual fire locations from the previous day obtained from NOAA?s NESDIS Hazard Mapping System. The dispersion simulation consists of two parts: 1) a 24 h analysis simulation run for the previous day, and 2) a 48 h forecast simulation, which assumes that yesterday's fires will continue to burn for the next two days. The smoke particle positions at the end of each analysis period are used to initialize the next day's analysis simulation. | smoke-pdd_.pdf |
