DISCUSSION

Issued at 231 AM CDT Tue Jun 30 2026

Rain-free and warm conditions will continue through the weekend as we remain under the southwestern edge of a mid-level ridge. High temperatures will be in the 90s, with heat index values between 100- 108, leading to a moderate HeatRisk. The ridge will weaken later in the weak, increasing moisture (PWAT values increasing to 1.75-2.00") and allowing shortwaves to ride around the southern periphery. Even with the increased moisture, reduced subsidence will keep shower and thunderstorms chances low (5-15%), focused mainly along the seabreeze over the Coastal Plains.

Confidence in the forecast begins to break down early next week as model solutions vary widely.
