After rounds of rain and thunderstorms on Friday and Sunday, a third round appears to be in the works for the middle of next week. Model guidance indicates that an upper-level low is likely to move into the Southern Plains by next Wednesday and Thursday. Deep Gulf moisture will spread into the Southern Plains ahead of this low, leading to the potential for heavy rainfall. There remains some disagreement in timing and placement of the upper-level low, and thus the heavy rainfall. While it is too early to know the exact amounts of rainfall, the latest data suggests that the primary threat towards the middle of next week would likely be heavy rainfall and flooding rather than severe thunderstorms, though severe weather cannot be ruled out either. We will continue to refine the details over the coming days, and should have a better handle on this third system over the weekend.
