DISCUSSION

Issued at 124 PM CDT Sat May 23 2026

While the main show has moved through this afternoon, can't completely rule out the possibility for a few showers and storms mainly in the Coastal Plains the rest of today and tonight. For right now we've blown through all of the instability in the area (temps have fallen into the 70s), so think chances are very low this afternoon. Models suggest a return of instability this evening and overnight, especially over the waters. While we should not see widespread heavy rain, as saturated as the ground is, it wouldn't take much for some minor flash flooding, so will leave the flood watch in place at this time.

After Sunday we'll loose the very deep moisture over the region temporarily. Thus, while we still have a mid-level low rotating over North Texas, we should drop rain chances back to low levels for Monday and Tuesday. Our next system is close on our heels though an will be here Tuesday night into Wednesday with another bout of very deep moisture with PWAT values near 2 inches. This disturbance will move through much more quickly though, so rain chances are mainly Tuesday night through Wednesday night. Could see an inch or two, and we do have a marginal risk for flash flooding on Tuesday associated with it because of the rain we've been seeing, so a watch may become necessary.

High temperature through mid-week will hover a bit below normal, mainly in the 80s for the entire area. Once the next system moves out, ridging an a more substantial southerly flow above the surface will warm temperatures back to right around normal levels.
