7. The rains continued into the afternoon and died down by 5pm. Examine the 48-hour rainfall totals, the latest Flash-Flood Guidance, and the forecast discussion from the Norman WFO.

  • What portions of Oklahoma received the most rainfall?
  • How have the guidance values changed in this region, compared to those from the day before?
  • What are the main hazards facing southwestern and southern Oklahoma?



Answer.

  • Much of western, central, southern and northeastern Oklahoma has received more than two inches of rainfall in the past two days.
  • In the areas which received the heaviest rains, the FFG values have dropped, especially for the one- and three-hour guidance.
  • The main threat facing southern and southwestern Oklahoma is have precipitation and flooding.

The Bottom Line:

    An episode of heavy precip saturates the soil, making it harder for the soil to accommodate another heavy precip event.
