1. Examine Mesonet data from 2:30 p.m. What features are evident in this data? Compare the weather conditions in the Panhandle with the conditions in eastern Oklahoma. Answer

2. Look at the KTLX reflectivity image from 2:32 p.m. What feature is indicated in this plot? What features in Mesonet data are correlated with the reflectivity image? Answer

3. What happens to the reflectivity feature between 2:30 and 3:30 p.m.? What else happens in the radar data between 2:30 and 3:30 p.m.? Answer

4. Look at the Mesonet temperature, dew point, solar radiation, and wind fields at 4:30 p.m. How have they changed since 2:30? How do the temperature, dew point, and wind fields relate to one another? Answer

5. Look at the radar reflectivity image at 4:30. How does this plot and the location of the echoes relate to the Mesonet fields at the same time? Answer

6. Look at the radar echoes between 4:30 p.m. and 8:00 p.m. What is the general motion of the echoes? Do any of the storms move in a different direction from the overall motion? Answer

7. Notice the motion of the thunderstorm that moves from Caddo and Grady counties to Pontotoc and Coal counties between 4:30 and 8:30. Do any Mesonet data plots provide a reason as to why that storm behaved as it did? Answer

8. Notice the reflectivity values of the storm mentioned in question 7 while the storm is in Pontotoc County. What do you think might be seen on the ground at this time? Answer

9. Describe the evolution of the features noted in question 1 over the duration of this event. Can these Mesonet features be related to features in the radar data? Answer
