SPC Dry Thunderstorm Fire Weather Outlook for Days 4 through 8 This product provides a daily categorical forecast of critical fire weather conditions for dry thunderstorms in the 4 through 8 day period.The National Centers for Environmental Prediction (NCEP) Storm Prediction Center (SPC) provides Day 1, Day 2 and Day 3-8 Fire Weather Outlooks (narrative and graphical) describing large-scale meteorological conditions in the lower 48 states which, when combined with the antecedent fuel conditions, favor the rapid growth and spread of a wildfire, should a fire ignition occur. These outlooks provide guidance for WFO forecasters and aid land management agencies in determining large-scale areas of fire danger risk. John Ferree 
SPC Day 4-8 Severe Weather Outlooks The Storm Prediction Center (SPC) Day 4-8 Severe Weather Outlooks are five separate graphics, one for each day (D4, D5, D6, D7, and D8), that depict areas of organized convection in the contiguous U.S. (CONUS). Two thresholds (15% probability and 30% probability) are used to depict these areas.The outlooks help users to adequately prepare several days in advance of an expected severe weather episode.The target audience includes NWS CONUS Weather Forecast Offices (WFOs), the public, media and emergency managers. products will provide five separate outlook graphics, one for each day (D4, D5, D6, D7, and D8).

Storm Based (Polygon) Special Weather Statements ER Threat based polygon warnings, or storm based warnings were implemented nationally in 2008 and essential to effectively warn for severe weather and flash floods. SB warnings show the specific meteorological threat area and are not restricted to geopolitical boundaries. By focusing on the true threat area, polygons help improve NWS warning accuracy and quality. ER initiated an experimental Polygon Storm Based Special Weather Statements (SBS) at Weather Forecast Offices (WFO) Blacksburg, VA and State College, PA in 2009 to promote increased accuracy of alerting the public to significant weather events. The SBS methodology allows the forecaster the opportunity to be spatially specific, eliminating large areas needlessly alerted when compared to issuing a county based SBS. Based on positive feedback from partners and users, the SBS has been transitioned to an official product for all ER WFOs. The Guidelines for SBS issuance are included in ER supplement 05-2010 Special Weather Statements. John Koch 
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. John Koch 
Changes to the Tropical Cyclone Public Advisory for 2015 The current NWS operational guidelines state that NHC and CPHC will issue public advisories (TCPs) at 2-hourly intervals whenever coastal tropical cyclone watches / warnings are in effect and coastal radars are able to provide reliable hourly center position estimates. When NHC and CPHC is issuing TCPs on 2-hourly cycles, hourly position estimates are issued (on the hour between TCP issuance) in the Tropical Cyclone Update (TCU; prior to 2013, the Tropical Cyclone Position Estimate was issued in these cases) to provide a continuous flow of information regarding the center location of a tropical cyclone when the center can be easily track with land-based radar. Although NHC typically mentions in the Tropical Cyclone Discussion and indicates in the TCP when 2- versus 3-hourly advisories will be issued, the less frequently used 2-hourly advisory cycle sometimes creates confusion among our core partners. This agenda item proposes that NHC and CPHC always remain on a 3-hourly TCP cycle whenever watches / warnings are in effect or a tropical cyclone is over land at tropical storm strength or greater. The elimination of the 2-hourly TCP cycle would preserve the issuance of public advisories at standard times during an event whenever watches or warnings are in effect. This change would also keep the issuance of public advisories out of the interval when NHC and CPHC forecasters are preparing the next forecast (e.g., the 9 a.m. intermediate advisory B must be prepared and sent while the 11 a.m. forecast is being developed). Maintaining public advisories on a 3-hour cycle will alleviate workflow issues while the new track and intensity forecast is being prepared and wind and surge watches / warnings are being collaborated.

Mountain Pass Forecast The Mountain Pass Forecast allows customers to check the forecast for significant highway passes for the next three days. Passes were chosen for this product based upon the frequency of calls to the WFO concerning weather at the pass and potential for impacts to travelers and commerce.The forecast consists of a text product that can be accessed via a web page John Lovegrove 
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. John S. Eise 
National Digital Forecast Database Extensible Markup Language National Digital Forecast Database (NDFD) Extensible Markup Language (XML) is a service providing the public, government agencies, and commercial enterprises with user selected components for point locations of the National Weather Service?s (NWS) data embedded in XML elements. NDFD XML provides users the ability, using a machine-to-machine paradigm, to retrieve the XML-wrapped data via the Internet. This web service is provided using the SOAP protocol.... John Schattel 
Tactical Decision Aid The Tactical Decision Aid (TDA) web page for the Terminal Radar Approach Controller (TRACON) highlights forecasts of thunderstorm potential for the TRACON's aircraft arrival corner posts. These forecasts will be updated hourly during periods of convective weather (occurring or forecast) and every four hours during periods of no convective weather. Forecasts will cover a 4 hour time frame. Forecast output will be a color-coded, bar graph indicating the hourly probability of thunderstorm activity at each corner post during the upcoming 4 hour period. John Werth 
Weeks 3-4 Temperature Outlook The National Weather Service, Climate Prediction Center delivers real-time products and information in order to monitor and predict climate variations and their potential associated impacts on timescales from weeks to about 1 year. The objective is to promote effective management of climate risk and a climate-resilient society. The Climate Prediction Center has added the Week 3-4 Temperature Outlook to its suite of products. The outlook consists of two components. These are (1) a temperature outlook map targeting the combined Week 3-4 outlook, and (2) prognostic map discussion (PMD) text explaining the rationale for the forecast. Jon Gottschalck  
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. Joseph Kunches 
Lightning Strike Density Product The Lightning Strike Density product is a gridded and graphical depiction of the density of lightning strikes. Units for the gridded product (GRIB2) as per WMO requirement are in SI units and are (number of strikes) m-2 sec-1 . These units require a scaling factor of 10 11 (11 is an exponent) to convert to km-2 min-1. The gridded forms are written to 8 km x8 km resolution and are generated in 15 and 30 min collectives. The lightning strike density product is based on the ground based Vaisala GLD360 global lightning network and is capable of detecting cloud-to-ground strokes, cloud-to-ground flash information and survey level cloud lightning information. Lightning Strike Density, as opposed to display of individual strikes, highlights the location of lightning cores and trends of increasing and decreasing activity. It is also a parameter that is useful to compare cloud to ground capabilities from different sources of lightning data. Joseph Sienkiewicz
