Experimental Aviation Weather Center Impacts Terminal Aerodrome Forecast (TAF) Board The experimental AWC Impacts TAF board is a time series display of weather conditions at select airports across the United States. Each box (hourly forecasts from TAF) is color-coded based on the level of the hazard. White represents no impact, yellow slight impact, orange medium impact, and red high impact. The letters in the box represent the cause of the hazard. They are as follows: -CIG – Ceiling (hundreds of feet, Above Ground Level [AGL]) -VIS – Visibility (statute miles) -WX – Weather (see legend) -WSpd – Wind speed (knots) -WGust – Wind gusts (knots) Mike Bettwy Approved for Operational
Experimental AWC PIREP Online Submission Form Pilot Reports (PIREPs) are reports of meteorological phenomena encountered in flight. These reports assist other pilots, dispatchers, and flight planners with flight plan preparation, situational awareness, and operational decision making. The PIREPs are integrated into the NWS forecast production process to help improve the accuracy of the forecasts, which include human generated products such as AIRMETs and SIGMETs as well as automated products such as the Graphical Turbulence Guidance (GTG), the Current Icing Product (CIP) and the Forecast Icing Product (FIP). PIREPs are particularly valuable in areas where surface-based observations are unavailable. The Aviation Weather Center PIREP online submission form enables registered users to enter PIREPs electronically, which will be distributed and displayed graphically on the Aviation Weather Center’s website www.aviationweather.gov. Users will be able to register at www.aviationweather.gov/user and submit their PIREPS at www.aviationweather.gov/airep/submit. All users will be subject to validation on the basis of having (1) an active pilot’s license (2) a .gov or .mil email address or (3) a group ID number for airlines. All other account requests will be evaluated on a case by case basis. Mike Bettwy Approved for Operational
Experimental Forecast of Reference Evapotranspiration for Short Canopy Vegetation (CR) The experimental reference evapotranspiration forecast will be displayed as a graphic of gridded data within the WFOs county warning area. The forecast is the expected amount of daily reference evapotranspiration in hundredths of an inch for the next 7 days and a total reference of evapotranspiration for the 7 day period. The forecast is calculated by standardizing on the tall canopy vegetation (50 cm full cover alfalfa) algorithm. This product will be issued three times a day around 5 am, 12 pm, and 4 pm local time.

Experimental Graphical Forecasts for Aviation In May 2015 the National Weather Service received a formal request from the Federal Aviation Administration (FAA) for the NWS to cease production of textual Area Forecasts (FAs), contingent upon the provision of equivalent meteorological information in support of aviation.The Graphical Forecasts for Aviation include observations and forecasts valid for the continental United States. Observational data and warnings are time synchronized and available by the hour for the current time and the prior six hours. Hourly model data and forecasts, including National Digital Forecast Data (NDFD), are available to 15 hours in the future. Wind, icing and turbulence forecasts are available in 3000 ft. increments from the surface up to 18000 ft. MSL, and in 6000 ft. increments from 18,000 MSL to FL420 (42,000 ft. MSL). Turbulence forecasts are also broken into LO (below 18,000 MSL) and HI (at or above 18,000 MSL) graphics. A maximum icing graphic and maximum wind velocity graphic (regardless of altitude) are also available.Multiple fields of interest are combined in categories that the user is able to select from the top level Weather menu. The data for each category is determined by the time period, observations (current time and the prior six hours) and forecasts (valid up to 15 hours in the future). Additional information is available in text format when mouse-clicking on the map or using the hover function. The “Configure” menu enables the user to customize the satellite and radar displays in addition to choosing parameters for the observations and aviation advisories displayed. Imagery, observations, and forecast graphics are overlaid on high-resolution basemaps from ESRI, including colored relief, satellite and street views. Overlays include navigational aids, airports, and heliports for the entire United States. More detail is revealed as you zoom in and individual layers can be turned on or off independently.

Experimental Hurricane Threats and Impacts Web Interface The experimental Hurricane Threats and Impacts Web Interface (HTI-Web) is an internet-based decision-support service designed to help users quickly interface with local hazard information whenever tropical storm and/or hurricane watches and warnings are in effect along the United States East and Gulf coasts, including Puerto Rico. Local threat assessments and corresponding potential impacts information about tropical storm or hurricane wind, storm surge, flooding rain, and tornadoes are provided by coastal Weather Forecast Offices (WFOs). Select preparedness information is also provided. Mike Dion Approved to Discontinue
Experimental Impact Based Warnings This is an expansion of the NWS Experimental Central Region Impact Based Warning demonstration in 2012 and 2013.Severe Thunderstorm Warning (SVR), Tornado Warning (TOR) and Severe Weather Statement (SVS) products will be stratified into categories distinguishing extreme cases from base convective warnings. Additional enhanced wording will be included to convey information about associated impacts, specific hazards expected, and recommended actions, both within the bullet statements and as part of the tag line codes.Based on feedback from the Central Region 2013 Experimental Impact Based Warnings, the 2014 demonstration will include some changes. The most significant change for the 2014 national experiment is that the impact statements for “CONSIDERABLE” and “CATASTROPHIC” serve as markers of confidence of tornado occurrence, with both reflecting an “elevated tier” of tornado damage and risk. The term CATASTROPHIC will only be used when a tornado is striking an actual community. Issuing enhanced convective warnings in 2014 will be the 38 Central Region Weather Forecast Offices (WFOs), 5 WFOs within NWS Southern Region (Norman, OK; Tulsa, OK; Jackson, MS; Lubbock, TX and San Angelo, TX); 1 WFO within NWS Eastern Region (Blacksburg, VA); and 2 WFOs within NWS Western Region (Great Falls, MT and Glasgow, MT).

Experimental Impacts Terminal Aerodrome Forecast (TAF) Board The Aviation Weather Center (AWC) experimental Impacts Terminal Aerodrome Forecast (TAF) board is a time series display of weather conditions at airports with significant impact on the National Airspace System (NAS) across the United States. Each box (hourly forecasts from TAF) is color-coded based on the level of the impact, defined by thresholds unique to each individual airport. White represents no impact, yellow slight impact, orange moderate impact, and red high impact. The letters in the box represent the cause of the hazard (including CIG, VIS, WX, WSpd, WGst).The AWC experimental Impacts TAF Board allows the aviation community to quickly ascertain the specific weather hazards at key airports across the United States, based on the TAFs. Information on the timing and level of impact are also included. This data is displayed graphically on the AWC’s testbed website at: http://testbed.aviationweather.gov/taf/board. The display assists dispatchers and flight planners with flight plan preparation, while also raising situational awareness and improving operational decision making. The AWC experimental Impacts TAF Board is also meant to consolidate pre-existing situational displays into a single, authoritative source. Mike Bettwy Approved for Experimental Implementation

Experimental Mixed Case Letters in WFO Text Products Many NWS partners and users have identified the need for NWS text products to be provided in mixed case letters and to include an expanded punctuation and character set. Previously, national Public Information Statements (PNSs), including national Service Change Notices (SCNs) and national Technical Implementation Notices (TINs), were provided in mixed case letters with an expanded punctuation/character set for a risk reduction effort using non-operational products: (http://www.weather.gov/os/notification/scn10-28mixed_case.txt). This experimental PDD expands the risk reduction effort to a few operational, but non-critical, Weather Forecast Office (WFO) text products: the Area Forecast Discussion (AFD), the Regional Weather Summary (RWS) and local PNS’s (including local SCN’s and TIN’s) for four WFOs: Kansas City/Pleasant Hill, MO - EAX Louisville, KY -LMK Spokane, WA - OTX Tallahassee, FL - TAE Art Thomas Approved for Operational
Experimental National Spot Forecast Webpage NWS Spot is a website where NWS customers can request a spot forecast. The customer answers form questions on the website and then the website will compose an STQ text product that is sent to the AWIPS of the Forecast Office that is required to write the forecast. The forecast is generally composed on AWIPS as an FWS text product and transmitted like any other text product that is issued by the forecast office. The NWS Spot website databases these FWS products. Each FWS product includes a “.TAG” line, which helps the NWS Spot website associate each forecast request with a completed forecast. Spot forecasts are a critical mission of the National Weather Service. These forecasts are needed (for example) for those fighting wildfires, conducting prescribed burns, cleaning up HAZMAT incidents (like deepwater horizon), for search and rescue operations, and other critical operations, as needed.

Experimental NHC/TAFB Satellite Rainfall QPE and QPF WebPage (graphical portion) Experimental Comment period for the graphical portion of this webpage has been extended through November 2014. This experimental webpage provides event-driven satellite-based quantitative precipitation estimates (QPE) and model-derived quantitative precipitation forecasts (QPF) for tropical cyclones and tropical disturbances affecting areas within the National Hurricane Center and Central Pacific Hurricane Center areas of responsibility (AOR). The experimental product represents an improvement over the existing text-only satellite precipitation estimate product which is based on the Griffith-Woodley technique developed in the 1970s. The experimental product provides more robust satellite-based precipitation estimates from the Naval Research Laboratory (NRL) Blended and the Climate Prediction Center (CPC) QMORPH techniques and a time-matched forecast from the Global Forecast System (GFS) in tabular text and storm centered graphical formats. A graphical version of these precipitation estimates is also provided. In addition, the experimental product provides a graphical 24 hour QPF from the Princeton Geophysical Fluid Dynamics (GFDL), the NOAA Hurricane Weather Research and Forecast (HWRF), and the GFS models. The target audience for this product primarily includes the forecast centers in the Caribbean, Mexico, Central America, and the Eastern and Central North Pacific. . In addition, decision support service (DSS) entities would have access to targeted QPF guidance that may be of assistance for distributing and directing resources to areas impacted by heavy rainfall Hugh D. Cobb Approved to Discontinue
