Digital Wind and Wave Forecasts on Inland Lakes and ReservoirsWind 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.
Dry Lightning Potential IndexThe Dry Lightning Potential Index (DLPI) is a graphical product produced by forecasters at WFO Las Vegas (VEF) using GFE/IFPS. Ratings of Dry Lightning potential (numbered from 0 through 6) for the next three days (today, tomorrow and the next day) are calculated using forecasts of boundary layer relative humidity and static stability. The DLPI is intended to be used as general guidance, primarily for planning purposes. The DLPI is intended as a seasonal product, issued from June through October, when active wildfires are most likely to occur in our forecast area
Eastern Pacific Hurricane Season OutlookThe Climate Prediction Center (CPC) issues the Hurricane Outlook for the eastern Pacific east of 140? West. No outlook, however, can give certainty as to whether or not a particular locality will be impacted by a tropical storm or hurricane in any given year. CPC issues this outlook in cooperation with the Tropical Prediction Center and NOAA?s Hurricane Research Division.
Eastern Region National Digital Forecast Database (NDFD) Graphic Forecast DisplaysThe National Oceanic and Atmospheric Administration (NOAA) National Weather Service (NWS) National Digital Forecast Database (NDFD) Graphic Forecast Displays (http://www.erh.noaa.gov/ndfd/graphical/sectors/ccc.php)where ccc is the WFO ID, are web-based presentations of digital forecast data originating from local Weather Forecast Office (WFO) digital databases. The data is displayed in a graphical form on a local scale.
El Nino/Southern Oscillation (ENSO) Diagnostic DiscussionThe Climate Prediction Center (CPC) issues this monthly bulletin to provide insight into climate outlooks by reviewing the potential effects of the ENSO.
Enhanced Product addition of Max Wind-Hail Size Coding Tag for Severe Thunderstorm Warnings and associated follow up staThe Central Region Severe Thunderstorm Warning (CR SVR) is an alphanumeric product providing short-fused warning in¬formation on hazardous conditions associated with thunderstorms which are expected to pose a threat to life and/or real property. This product is prepared by each National Weather Service (NWS) Weather Forecast Office (WFO) for their County Warning Area (CWA) of responsibility. Integrated Warning Team workshops, as well as several societal impacts groups, have indicated a desire by many emergency managers for a concise tag line on the end of the SVR product identifying maximum hail size and wind speeds expected for a given SVR warning. Local area sirens are typically alarmed for tornadoes only. Decoding this tag line will facilitate the capability for local area EMs to trigger sirens for particularly dangerous severe thunderstorm events when conditions exceed locally developed thresholds for thunderstorm induced wind and or hail size.
Enhanced Product National Implementation of the use of 1 inch Diameter Hail CriteriaThe Severe Thunderstorm Warning (SVR) is an alphanumeric product providing short-fused warning in¬formation on hazardous conditions associated with thunderstorms which are expected to pose a threat to life and/or real property. This product is prepared by each National Weather Service (NWS) Weather Forecast Office (WFO) for their County Warning Area (CWA) of responsibility. In the Western Region (WR) and Central Region (CR) a Severe Thunderstorm Warning is currently being issued experimentally based on expectation of winds gusting to 58 mph or greater and/or hail of one (1) inch diameter or greater. Pending successful completion of this experiment, all NWS sites will issue Severe Thunderstorm Warnings based on these criteria.
Enhanced Winter Weather Guidance Product SuiteThe Hydrometeorological Prediction Center (HPC) proposes to produce probability guidance for three specific snow/sleet accumulation thresholds per forecast day out to Day 3. HPC will also generate separate probability graphics for the exceedance of freezing rain. In addition a single graphic will depict both HPC forecast position of significant surface low pressure centers over the contiguous U.S. and conveyance of uncertainty of the forecast position. This will be depicted in 12 hour increments out to Day 3.
Enhancement to National Spot Webpage: HYSPLIT Trajectories Request Function The Weather Forecast Office (WFO) NWS Spot webpages provide a nationally uniform portal for NWS customers to request, receive, and leave feedback for site specific spot forecasts. As of September 19, 2011, all WFO NWS Spot webpage hosted a new functionality for requesting HYSPLIT (Hybrid Single Particle Lagrangian Integrated rajectorymodel) trajectory runs from NOAA’s Air Resources Laboratory (ARL) on an experimental basis. On October 20, 2013 this functionality became operational. Trajectory elements will be available based on the North American Mesoscale Model (NAM) for the CONUS and on the Global Forecast System (GFS) for Alaska and Hawaii. The HYSPLIT trajectories Request Function will allow users to request HYSPLIT trajectory runs at 500, 1500, and 3000 meters for the latitude/longitude of the spot request. The trajectory runs will begin at the specified ignition time on the spot request. To request HYSPLIT trajectories with a spot request, the user must enter the phrase ..."hysplit to requester email address" in the remarks section of the spot request form. The HYSPLIT trajectory raw data, as well as gif and kml files, will be sent to the specified email address.
Enhancement to the National Snow Analysis: NOHRC Snow Model and Forecast Products ExpansionThe 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.
Ensemble Trace plotCurrently 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 Ensemble Trace Plot prepared by the North Central River Forecast center (NCRFC) will be issued as a Web page graphic. The graphic will be for the NCRFC?s area of responsibility. It will be issued once a month (after the Climate Prediction center (CPC) outlooks are released at mid-month). It will cover the three month period after the issuance (for example, graphic released around May 26 will cover June-August period).
Expected Value plotDescription: Currently the National Weather Service River Forecast Centers and Weather Forecast Offices produce a wide variety of river forecasts to indicate current and future river conditions. The Expected Value graphic indicates timing and confidence levels for forecast stages for a selected time-frame, generally 90 days. This would provide an overall range of expected hydrologic conditions based on computed probabilities. The Expected Value Graphic will be issued as a web-based graphic for NCRFC?s area of responsibility. It will be issued once a month after the Climate Prediction Center outlooks are released at mid-month to cover the ensuing three month period (i.e. graphic issued around May 26 will cover the period from June-August).
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
Extreme Wind Warning (EWW)The Extreme Wind Warning (EWW) is a text product prepared by the National Weather Service (NWS) Weather Forecast Offices (WFOs). The product warns of imminent or impending extreme winds associated with a landfalling hurricane.
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)
Fire Weather Planning Forecast (FWF) Text Format– Due to varied terrain, vegetation and climatology, the Fire Weather Planning Forecast (FWF) in the western U.S. requires varying amounts of forecaster editing following production of draft text from GFE formatters. This FWF text format utilizes left-justified asterisks to begin each line of text. The asterisks help maintain proper word wrapping and indentations in the AWIPS text editor, significantly reducing the amount of time needed to “post edit” the product before dissemination. The format change is accomplished through use of a FWF GFE formatter developed by Western Region.
Fire Weather Point Forecast Matrix Land management agencies in Georgia and North Carolina have expressed a need for easily accessible tabular forecast data that is tailored toward fire behavior applications. A fire weather version of the Point Forecast Matrix (PFM) table fits this need well because it allows agency specialists to quickly run simple fire behavior models for planning purposes. The product is called the Fire Weather Point Forecast Matrix (PFW) and is generated routinely for the National Fire Danger Rating System (NFDRS) sites or other areas as determined by the users. This additional data will help land management agencies to ensure the safety of fire crews as well as better plan prescribed burns and other projects in a cost and resource effective manner. Also, land managers have expressed a need for better tools to predict and manage smoke dispersion. They have also requested that the NWS include an Atmospheric Dispersion Index (ADI) and Low Visibility Occurrence Risk Index (LVORI) in the PFW product. WFO Fire Weather PFW’s are generated for the Remote Automated Weather Station (RAWS)/NFDRS sites using an edited version of the standard PFM formatter. This formatter produces needed fire weather parameters from the local WFO’s Digital Forecast Database (DFD). PFW's can be generated for any grid point in a DFD based upon user request. The web delivery of the product for fire weather customers will include a disclaimer at the top of the page stating “This product is for planning and review purposes only and is not to be substituted for an official fire weather spot forecast. The data displayed are calculated from a 5.0 by 5.0 km digital database and only approximates weather conditions in highly varying terrain. Please relay any comments you have to your local NWS office. An example of the PFW can be seen at: http://www.srh.noaa.gov/productview.php?pil=GSPPFWGSP .
Fire Weather Threat 4-Panel GraphicThe Fire Weather Threat 4-Panel Graphic displays on the Internet several parameters that are critical for fire weather. In the upper left corner of the graphic is a ?Red Flag Risk Index? based on forecast minimum relative humidity (RH) and forecast maximum sustained wind. In the upper right hand corner is the Red Flag Risk Index for the current hour based on the GFE RH and wind observation database. In the lower left corner is the Haines Threat Index based on the forecast high level Haines Index and forecast minimum relative humidity. A second graphic is available based on the Forecast Haines Index and the current relative humidity from the GFE observation database. In the lower right hand panel three graphics reside. The probability of 25% or lower RH, 15% or lower RH, and the current observed RH.
Fire Weather Watch/Warning DisplayThe Fire Weather "Red Flag" Watch/Warning Display provides an HTML visual display of all fire weather "Red Flag" watch/warnings that are currently in effect across the western U.S.
Five Day Sea Ice ForecastForecast sea ice conditions over the waters surrounding Alaska valid at the day five period.
Flash Flood Potential IndexThe Flash Flood Potential Index (FFPI) is a text product produced by forecasters at the WFO SGX and WFO LOX using objective forecasts techniques based upon model data. Ratings of flash flood potential (numbers 0 through 4) for the next two days (today and tomorrow or tomorrow and the next day - depending on the issuance time) are calculated using precipitable water, winds aloft (700 mb), and forecaster knowledge of other atmospheric factors such as stability and atmospheric capping. The FFPI is issued during flash flood season from June 1st through September 30th.
Flash Flood Potential RatingThe Flash Flood Potential Rating (FFPR) is both a text and graphical product produced by forecasters at the WFO SLC using GFE/IFPS. Ratings of flash flood potential (numbers 1 through 6) for the next two days (today and tomorrow or tomorrow and the next
Forecast Icing Potential (FIP)The Forecast Icing Potential (FIP) product is an automatically-generated forecast index of icing potential developed by the In-Flight Icing Product Development Team sponsored by the Federal Aviation Administration?s Aviation Weather Research Program.
GIS Compatible NDFD Data on the WFO Internet PageNOAAs National Weather Service (NWS) Weather Forecast Offices (WFOs) produce graphical forecasts for the National Digital Forecast Database (NDFD). The NDFD forecasts are available to the public in GRIB2 format, a World Meteorological Organization standard. Unfortunately, this format is not widely used outside of the meteorological community. In this project GRIB2 files from the MFR county warning and forecast area are converted to shapefile format and posted to the internet webpage.
Global Tropics Hazards/ Benefits AssessmentThe Global Tropics Hazards/Benefits Assessment, issued by the Climate Prediction Center (CPC), provides an outlook for the upcoming week 1 and week 2 time periods for areas expecting extensive and persistent enhanced / suppressed rainfall and regions where conditions are especially favorable / unfavorable for tropical cyclogenesis.
