With little convection impacting the NAS yesterday afternoon the forecasters had time to review an archived case of a particularly impactful day. The forecaster looked at the CAWS graphics created on June 18, 2015 for areas being impacted by the remnants of tropical cyclone Bill. The forecaster was tasked with creating a "perfect" CAWS with the knowledge of how the weather evolved during the day. They looked at CCFP, INSITE, radar data, and the CAWS graphics from that day. Again, different colors, polygon fills, and arrows were used to see if more information could be conveyed in the graphic without becoming too cluttered.

Yesterday was not as impactful of a weather day in terms of convection. The CAWS forecasters did focus some time in the morning to issue CAWS for convection off the coast of the Carolinas and a CAWS for convection impacting the Jacksonville, FL vicinity. The forecasters experimented with different colors and polygon fills. The fills are used to indicate coverage while the different color text box highlighted peak time of impact. Any thoughts on these techniques?

We are on Day Two of the Summer Experiment! Now that we are more oriented with desk tasks and goals we are experimenting with new techniques. For example, the CAWS forecasters are trying out the effects of changing the line weight and color on the graphic. On the first image below, the use of a bolder line indicates higher confidence. On the second image, a different color (pink) is used to indicate when the greatest impact to the terminal would be.

Today is the first day of the 2015 AWT Summer Experiment. We are very excited to host a wide range of visitors from the FAA community, NOAA, academia, and Industry. The first part of the morning focused on getting familiar with the different experiment desks and tasks. By mid-morning our CAWS production desk and support desks were delving into today's impacts while the Ceiling and Visibility desk and Tropical Graphics desk began working on their products. So far, two CAWS graphics have been issued. One is for the Ohio Valley for later on this afternoon and the second one is for impacts to Atlanta.
