6. At 4:00 am CDT on the 14th, the Norman WFO issued the following Warning Decision Update.
- What does it tell you about using radar-estimated precipitation for the rest of the day?
Answer.
- The radar is underestimating precipitation due to "warm rain processes" ... a buzzword the storm has almost no hail (a very, very deep layer of the atmosphere is above freezing, limiting hail growth).
- Radar-indicated precip may significantly underestimate rainfall data.
- Gauge data is always valuable to "ground truth" radar data, but it is even more so during this event.
The Bottom Line:
- Warning Decision Updates (Norman WFO) and Mesoscale Updates (Tulsa WFO) can provide extremely valuable information about developing situations.
- These products are especially useful for information that does not fit into the "standard" WFO products.
