Product Name Brief Description Submitter Date Entered
Addition of Experimental Waterspout coding to the Special Marine Warning and Marine Weather Statement for all Coastal WFOS. NWS Central Region offices have issued Special Marine Warnings (SMW) and Marine Weather Statements (MWS) with tags for hail and wind as an operational product format since 2010. The purpose of this PDD is to change how these hail and wind tags are encoded to bring them into conformity with how they are done within the Severe Thunderstorm Warning product, and to introduce a new tag to help users better identify the potential threat from waterspouts for all coastal WFOs Brian Hirsch 2014-04-25
Experimental Graphical Wind Against Current The experimental product is a graphical depiction of the maximum 24 hour wind component from the NWS Global Forecast System that opposes the surface current of the Gulf Stream system as defined by the U.S. Navy High Resolution Coastal Ocean Model (NCOM).

Experimental Hold Over Threat Index (Elko) In the Great Basin a significant threat to large fire spread occurs when relative humidity is low and strong winds develop a day or two after a lightning event. The Holdover Threat Index is a GFE graphic that displays the threat of “holdover fires” for the WFO Elko county warning area. It can also be displayed on the web with all other fire weather graphical forecasts. This graphic is intended to heighten awareness for days when conditions are favorable for smoldering fires to grow. Users of this product are the fire weather community. Claudia Bell 2014-05-14
Experimental Severe Weather Impact Graphics This product is a graphical depiction of each short-fuse warning product issued by the NWS Weather Forecast Office (WFO), CONUS only, with the inclusion of impact information to supplement the graphics. "Short-fuse warnings" include Tornado, Severe Thunderstorm, Flash Flood and Extreme Wind Warnings. Brian Walawender 2014-06-03
Experimental Collaborative Decision Making (CDM) Convective Forecast Planning (CCFP) Guidance The experimental CDM Convective Forecast Planning (CCFP) guidance is a graphical representation of convection meeting specific criteria of coverage, intensity, echo height, and forecaster confidence. The experimental CDM Convective Forecast Planning (CCFP) guidance graphics are produced every 2 hours and valid at 2-, 4-, 6-, and 8-hours after issuance time. The experimental CDM Convective Forecast Planning (CCFP) guidance will be automatically produced from the NOAA SREF, HRRR, HIRES ARW models, but will share the same format and be disseminated exactly as the human-produced Collaborated Convective Forecast Product. Additionally, to meet user needs, the experimental CDM Convective Forecast Planning (CCFP) guidance will be issued through March 1, 2016 Debra Blondin 2014-09-29
Experimental Gerling-Hanson Wind Wave Plots The experimental Experimental Gerling-Hanson Wind Wave Plots are graphical vector plots of predefined point guidance for up to six wave trains (direction, height, and period), and wind (direction, speed) through a five day period at six hourly increments. If the point is associated with a buoy location, the previous 24 hour observations, partitioned in the same manner as the forecast waves, are plotted in three hour intervals. The forecast wave information is from the Nearshore Wave Prediction System (NWPS) model output. The wind is derived from the official forecast gridded database so they are consistent with all other forecast products, such as the Coastal Waters Forecast. WFO Eureka has been providing the Experimental Wave/Wind (Gerling-Hanson Plots) on an experimental basis since 2010. The Gerling-Hanson plots have been very useful for the marine customers and the product has been expanded to other regions for comment and review. Troy Nicolini 2014-11-07
Experimental Beach Forecast Web Page The Beach Forecast Webpage is a website designed for beach goers to easily see hazards and forecasts along various beaches. This webpage is being developed for SR coastal Forecast Offices, and if feedback is favorable will most likely be expanded to other regions as well. This webpage offers rip current risks graphically, descriptions, and actions to take. The webpage also offers UV Index information. The map is clickable, and from there you get a weather forecast and also rip current risk and UV index information as well. The webpage offers links to the forecasts for the beach areas, water temperature when available, and other information such as links to lightning safety information and local radars.

Experimental Modernized Open Lakes Forecast for the Great Lakes This experimental enhancement to the Open Lakes Forecast will run parallel with the existing Open Lakes Forecast for the open lake areas on the Great Lakes. The product will provide advance notice to mariners of forecast weather, wind, and wave conditions in a tabular format. This format has been part of a Great Lakes Harmonization team between NWS and Environment Canada and is intended to test a product which can be created on bothe sides of the lakes and by both countries. Brian Hirsch 2015-02-05
Experimental Collaborative Aviation Weather Statement (CAWS) The Collaborative Aviation Weather Statement (CAWS) is a product (weather service) collaborated by National Weather Service (NWS) meteorologists, airline meteorologists, and other airline and Federal Aviation Administration (FAA) personnel. The CAWS focuses on specific, convective forecasts impacting the Core 29 airports and high traffic en-route corridors. The focus is event-driven, supporting the ability to more effectively initiate, adjust, or terminate planned or active Traffic Management Initiatives (TMI) to balance traffic demand in the constraint locations Michael Graf 2015-02-13
Experimental Short Range River Forecast Uncertainty (AHPS) A graphical hydrograph depiction of short-range river forecast uncertainty. The product provides probabilistic bounds for the river forecast in the context of high and low water thresholds used in AHPS. Ernie Wells 2015-02-25
Prototype Storm Surge Watch Warning Graphic The prototype storm surge watch/warning graphic highlights areas along the Gulf and Atlantic coasts that have a significant risk of life-threatening storm surge inundation from a tropical cyclone, displaying areas that would qualify for inclusion under a storm surge watch or warning under development by the National Weather Service. The graphic represents the first step of a phased implementation toward an NWS storm surge watch/warning, but for 2015 does not represent an official NWS watch/warning. The NWS plans to debut an experimental storm surge watch/warning in 2016. After incorporating both user and partner input, the NWS expects to make the storm surge watch/warning fully operational in 2017 John F. Kuhn 2015-04-07
Experimental Impact-Based Marine Hazard Grids Impact-based marine hazard grids (IBH) provide the marine community with a detailed depiction of expected adverse weather conditions. Unlike zone-based hazards, IBH also show parts of zones where no hazard is expected which allows for continued marine operations. The Weather Ready Nation concept calls for improving information to customers and partners to enhance decision support. Providing additional hazard details fills that requirement.

Experimental GATE Forecast Arrival and departure sectors for major airports, also called gates, are polygonal regions which roughly follow Air Route Traffic Control Center (ARTCC) low-level sectors where arrivals and departures to these airports will be routed. It is important to know whether significant weather, such as thunderstorms, could affect large portions of the sectors so that traffic can be rerouted, if needed, to other sectors. The Gate Forecast is a decision support algorithm that uses the High-Resolution Rapid Refresh (HRRR) model to determine whether there is the potential for thunderstorm activity in a particular terminal gate. The algorithm initializes with the HRRR composite reflectivity forecasts and then does a time lag ensemble using the previous three HRRR model runs. It creates a grid with the maximum composite reflectivity at each grid point from the three runs (for example, the 1 hr. forecast from the 18UTC run plus the 2 hr. forecast from the 17 UTC run and the 3 hr. forecast from the 16 UTC run). From that grid, a probability factor is computed. Low composite reflectivity equates to low probability. High reflectivity equates to high probability. The algorithm computes the gate sector coverage of these probabilities. If more than 1% of the sector is covered in low probability (.25 chance), the gate is colored yellow. If more than 4% of the sector is covered in high probability (.60 chance), then it is colored red. These are then computed for each forecast time from the HRRR. The product display overlays the sector boundaries on the current radar loop. The sectors are color-coded using a three tiered approach: • Green - no significant weather • Yellow - some significant weather that might affect some portions of the gate • Red - significant weather that could affect large portions of the gate Around each gate is an icon with the gate name and the forecasts for the next nine hours. Clicking on the icon will bring up a dialog box that shows the percent coverage of low (2560) thunderstorm probability, the three HRRR runs used in the forecast and the time of the last update.

Experimental Day 4-7 Winter Weather Outlook The Day 4-7 Winter Weather Outlook is a graphical probabilistic forecast depicting the probability of winter precipitation (snow/sleet) exceeding 0.25 inches (~6 mm) water equivalent over a 24-hour period. The product is comprised of 4 graphics showing the forecast for Day 4, Day 5, Day 6, and Day 7. The outlook is prepared twice daily by Weather Prediction Center (WPC) medium range forecasters David Novak 2015-06-24
