  1. The Evolution of NWS Aviation Weather Services in Chicago Mike Bardou National Weather Service Chicago

  2. Goals • Improve collaboration among the NWS, FAA, Commercial Airlines, and Airport Operators • Disseminate more frequent weather information • Increase service to aviation interests • Improve service delivery infrastructure • Develop improved tools for the forecaster • These are the keys to managing the impact of weather on the Chicago airspace and reducing weather related flight delays.

  3. Initial Efforts • 2-hr TAF updates on weekdays • Improved aviation AFD format • Increased collaboration between WFO and CWSU • Hourly updates to wind and POP/Wx grids • Listen in on FAA/Airline strategic planning telcons; better understand impacts of weather and forecasts

  4. www.weather.gov/zau • Developed as a one-stop source for Chicago Airspace Wx information • Development of wind and TS Tactical Decision Aids (TDA)

  5. www.weather.gov/zau

  6. www.weather.gov/zau

  7. Resources • Addition of 3 forecasters • cross trained as WFO and CWSU forecasters • allow a dedicated Aviation Desk 24 hrs a day/5 days a week • Addition of Aviation Services Improvement Meteorologist • allows for more interaction with customers and expansion of new services

  8. Evolution • Development of WFO/CWSU Aviation Team • integrate Science and Service aspects • build relationships and communication with customers • assess initial service enhancements • develop/implement new service improvements • analyze significant aviation weather events to better understand impacts and build forecaster knowledge base • Develop training for the user community

  9. Event Reviews

  10. Evaluation • Traditional • POD, FAR, CSI • Measures forecast against forecast models • We need to measure the IMPACT of our services • Wind shift lead time • Weather related delays • Multiple causes even when attributed to wx • Some delays are inevitable • Ideas?

  11. Evolution – TS TDA

  12. Evolution – Experimental O’Hare Winter Precipitation Outlook • Developed based on user feedback regarding winter operations and event reviews • Produced in GFE Scott Shelerud

  13. Evolution • Improved Airspace-specific Support • ARTCC • TRACON • ORD/MDW Towers • Enhanced ZAU Web page • Improved communication/coordination • NWSChat??

  14. Impact of the Day Top link would link to the bulletin Multimedia Briefing additional links to WFO products • Layer Approach • Base Layer – METARS • To the right CENTER specific windows for hazards • SIGMETs-ICE, TURB and TS • Approach and Arrival Gate forecasts • Compression winds (RUC) • If clicked; Side windows would ‘pop-out’ or replace the main display • Retain ‘roll-over’ capability to cycle through various map/displays O Current O Forecast O HAZARDS 1. PRIMARY DISPLAY AREA 2. For windows 2. and 3. NOTE: Non-OEP airports would display enroute graphics to indicate impacts. RED, YELLOW or GREEN lines. Hover or clicking the line (major jet routes) would indicate the problem and time. AWC CCFP during the summer and NWS SFC map with features for the winter. 3.

  15. Evolution - NextGen • Next Generation Air Traffic System • 4-D Cube of data • Additional gridded weather forecast elements • Ceilings • Visibility • Guidance for areas beyond TAF sites
