Below is National Weather Service Briefing for today (Wednesday, May 28, 2025) through Friday, May 30, 2025. The main takeaway is the potential for over 3 inches of rainfall, which could lead to flash flooding from today through Friday.
Today’s focus will be near the I-10 corridor. Isolated damaging wind gusts, small hail, and frequent lightning are possible.
A Marginal Risk (Level 1 of 5) of Severe Thunderstorms is in place today through Friday. Locally heavy rainfall may result in flash flooding on Thursday and Friday.
Severe Weather:
A moist and unstable air mass will be in place until a cold frontal passage on Friday night. Showers and thunderstorms are expected, mainly during the afternoons and evenings from today through Friday. The seabreeze moving inland will aid in developing isolated to scattered storms near I-10 today. In addition to the seabreeze storms, additional storms are likely on Thursday and Friday as the cold front approaches, with greater coverage expected both days. The main concerns are isolated damaging wind gusts and frequent lightning, but small hail will also be possible. The Marginal Risk (Level 1 of 5) from the Storm Prediction Center is currently in place from today through Friday (attached severe storm risk graphic). In particular, we cannot rule out an upgrade to a Slight Risk (Level 2 of 5) on Friday.
Heavy Rainfall:
The air mass will be anomalously moist, and with the approaching front, this will set the stage for the potential of heavy rainfall. While most locations will receive around 1-2 inches of rain, portions of the region (attached rainfall potential graphic) have at least a 50% chance of greater than 3 inches of rainfall. Locally heavy rainfall could result in flash flooding, especially for urban and poor drainage areas, where these higher amounts occur.
This Weekend:
Looking ahead, the weekend is looking dry and seasonably warm, with a more comfortable air mass in place.
