  14. Forecast Discussion • For 12Z Temperature: Describe the part of the conceptual model of the daily temperature cycle that provides the basis for the your forecast. • For the effect of cloudiness on 12Z or on 18Z temperature: State the criteria for whether or not clouds will affect the 12Z or 18Z temperature. Then identify the source(s) of the information that you use to make your forecast and the reasoning that you apply, including any assumptions that you make. • For the effect of a front on 12Z or 18Z temperature: State the criteria for whether or not a front will affect the 12Z or 18Z temperature. Then identify the source(s) of the information you used to make your forecast and the reasoning that you apply, including any assumptions that you make. • For the effect of temperature advection on 12Z or 18Z temperature: State the criteria for whether or not temperature advection will affect the 12Z or 18Z temperature. Then identify the source(s) of the information you used to make your forecast, together with the reasoning that you apply, including any assumptions that you make. • For your particular forecasting question, consult the Forecasting Tacticsdocument for details. • Your discussion should be detailed enough so that someone else could reproduce your forecast. • If necessary, use more than one PowerPoint slide for your discussion.

  15. Forecast Discussion (cont’d) • For 18Z temperature: Describe the conceptual model that provides the basis for the your forecast. (Use the annotated temperature plot on the next slide.) Then identify the source(s) of the information you used to make your forecast and the reasoning that you apply, including any assumptions that you make. • For 18Z wind speed or wind direction: Identify the sources of information that you use for making your forecast, together with the analysis and reasoning that you use. In particular, comment on the relative strengths and weaknesses of the NWS point forecast and the NAM forecast, and comment on how you factor them into your forecast. • For whether or not there will be precipitation in the 24 hours starting at 12Z tomorrow: Identify your source(s) of information and explain the analysis and reasoning that you use to make your forecast. • For your particular forecasting question, consult the Forecasting Tacticsdocument for details. • Your discussion should be detailed enough so that someone else could reproduce your forecast. • If necessary, use more than one PowerPoint slide for your discussion.

  16. Forecast:Write your forecast here just as you would enter it at the Iowa St. University Web site. Verification: • Archived meteograms • Archived weather maps for the West Coast, including fronts • Archived analyses of temperature and wind observations [Compare the appropriate observation(s) with your forecast. How would ISU score it?]
