DISCUSSION

Issued at 1013 PM CDT Sat Jun 6 2026

While drier conditions are on the way, Sunday into Monday will still feature some low to medium chances (15-40%) of showers/thunderstorms, mainly along and east of Yacc. Best time frame will be in the afternoon, and again late Sunday night into Monday morning as a few disturbances move overhead. PWATs still remain quite high (between 2 and 2.5 inches), so heavy rain will be possible leading to ponding of water on roadways and low lying areas, especially in areas that have seen heavy rain in previous days. While the remainder of the week looks mostly dry, could still see an isolated shower or thunderstorm along the sea breeze each afternoon. Temperatures will be quite warm with much of the region in the mid to upper 90s by Wednesday. Moderate Heat Risk (Level 2 out of 4) will prevail across the region and heat indices will reach between 100 and 110 degrees each day.

A moderate risk of rip currents continues through tomorrow.
