Increases efficiency of forecast operations Increases efficiency of forecast operations Generate TAFs quickly and maintain consistency Generate TAFs quickly and maintain consistency Capability for additional TAF sites Capability for additional TAF sites

4. Digital Aviation Services There is a demand for this information!

5. NWS Digital Aviation Services Today Participating WFOs On The Way Many have shown interest !

7. Hourly Graphical Forecasts Not just for aviation use!

8. Shadow TAFs Internal forecasts for airports not served by NWS TAFs Run in the background every 6 hours 0545, 1145, 1845, 2345 UTC No forecaster “intervention” Sent to NWS Verification Branch for processing Gives a sense of “gridded” verification Meets or exceeds GPRA IFR Metric

9. Shadow TAF Applications Google Map interface for Terminal Information Board

10. Shadow TAF Applications “Point and Click” capability for Ceiling and Visibility forecasts

11. TAF Applications Terminal Information Board

12. Internal Consistency Wind grids produce output for TAF and TDA

13. Consistency and Efficiency TDAs can be derived from grids

14. Role of TAFs Regulatory Forecast Product Part of Digital Aviation Services

15. Objective Provide hourly graphical forecasts of Ceiling and Visibility which represent prevailing conditions for the next 30 hours Forecast flight categories, not observations! Keep the process manageable for the forecasters Support a national digital database Allow TAFs to “drop out” of the database with little or no post-editing

16. Digital Aviation Services Populate grids out to 36 hours for: Populate grids out to 36 hours for: 00z, 06z, 12z, and 18z TAFs 00z, 06z, 12z, and 18z TAFs T, Td, Wind, Sky, Wx, Ceiling, Vsby, LLWS T, Td, Wind, Sky, Wx, Ceiling, Vsby, LLWS GFE formatter produces first cut of TAFs GFE formatter produces first cut of TAFs Forecasters review/transmit TAFs through AvnFPS Forecasters review/transmit TAFs through AvnFPS Grids updated every 3 hours / issue AMDs Grids updated every 3 hours / issue AMDs Meets 3-hour TAF requirements Meets 3-hour TAF requirements Other AMDs: Issued through AvnFPS Other AMDs: Issued through AvnFPS Need for timely Ceiling/Visibility analysis grid Need for timely Ceiling/Visibility analysis grid

17. Assessment Staff Feedback: Unanimously Positive Staff Feedback: Unanimously Positive No one wants to go back to writing TAFs! No one wants to go back to writing TAFs! Short Term forecaster no longer removed from GFE to compose TAFs in AvnFPS Product consistency no longer a problem Workload “shift” – no notable increase “Keep it simple” but have alternate methods available to help in a pinch. “Keep it simple” but have alternate methods available to help in a pinch. Tools available which use raw model data if MOS does not look reasonable (diurnal cumulus, stratus in particular) LLWS procedure calculates shear and ensures consistency from shift to shift – no more guessing from BUFKIT!

18. Assessment Operations are more efficient Operations are more efficient “Aviation forecaster” no longer needed on shift “Aviation forecaster” no longer needed on shift Grids/TAFs handled by Short Term forecaster Grids/TAFs handled by Short Term forecaster Most short term grids are completed at TAF time Most short term grids are completed at TAF time Shift in forecasting from point-based to areal-based Shift in forecasting from point-based to areal-based Immediate acceptance by staff Immediate acceptance by staff Much easier to compose TAFs Much easier to compose TAFs 00z/12z: Usually update first 6-12 hours only 00z/12z: Usually update first 6-12 hours only Easier to send multiple AMDs for 3-hour TAFs Easier to send multiple AMDs for 3-hour TAFs No initial drop in verification scores No initial drop in verification scores All sites improved!

19. Challenges Grids to TAFs Grids to TAFs “TAFs are too long!” (complex weather) “TAFs are too long!” (complex weather) Staff training held on “nuts and bolts” of GFE formatter Staff training held on “nuts and bolts” of GFE formatter Knowledge of Cat A and B thresholds / wind impacts Knowledge of Cat A and B thresholds / wind impacts Focus on first 12 hours...trends beyond that Focus on first 12 hours...trends beyond that Forecaster preference is to “post edit” and remove any extra FM groups Forecaster preference is to “post edit” and remove any extra FM groups Assumes some initial risk Assumes some initial risk Initial drop in scores possible, but they will recover Initial drop in scores possible, but they will recover Detailed hourly grids are a must Detailed hourly grids are a must Staff training/practice is crucial!
