DISCUSSION

Issued at 314 AM CDT Fri Apr 3 2026

Above normal temperatures will continue through Friday and into Saturday before the arrival of our next cold front Saturday night. Confidence continues to increase with the timing of the front while still remaining a little cloudy in respect to the storm total accumulations. The ingredients for moderate to locally heavy will be in place with PWAT values between 1.8-2.0", mid-level PVA and diffluence aloft. Current thinking for storm total rainfall amounts Saturday through Monday remain between 1-2" with a worst case scenario of over 3". Therefore, the Weather Prediction Center has issued a Marginal Risk (at least 5%) of flash flooding for all of South Texas for Saturday and Sunday. Confidence on rainfall amounts should increase within the next 24 hours as the feature begins to enter the domain of the high resolution models. Below normal temperatures are expected Sunday through Wednesday with near normal temperatures returning towards the tail end of the work week.
