KEY MESSAGES

Updated at 616 AM CDT Tue Jun 2 2026

- Minor to moderate Heat Stress conditions across the region through the week.

- Low to medium (20-50%) rain chances return Tuesday and continue each afternoon through the end of the week.

DISCUSSION

Issued at 124 AM CDT Tue Jun 2 2026

The chance for showers and storms will return to the region this week as the ridge weakens. A mid-level low developing off the southern California coast will funnel moisture into the area as well as residual shortwave energy. Onshore flow from the Gulf will advect deep tropical moisture through the week in addition to this. There will also be additional shortwaves riding around the periphery of the ridge which will further enhance development that is expected to couple with the seabreeze each day. These factors will allow for showers and thunderstorm activity to increase beginning today through the remainder of the week into the weekend. When the low is expected to push across the region to the north later this week (Friday/Saturday), it will send more embedded shortwave energy into the region. This will also be when the highest surges of moisture will be expected. The likely outcome is this period will be the wettest of the week. Due to this and antecedent conditions with saturated soils, WPC has included the region in a Marginal Risk for Excessive Rainfall beginning Thursday. This will mainly be for the Brush Country and portions of the northern Plains. In terms of Friday, during this package all of South Texas is included in a Marginal Risk. Wouldn't be surprised if portions of the region remained in the risk for Saturday as well at the time of writing this. Model guidance supports PoP chances lingering into Saturday before tapering off Sunday as the disturbance clears the region. Will continue to monitor this as we progress through the week.

Expect warmer conditions through this week with highs in the 80s and 90s across the region with heat indices around 100-105. This will lead to minor to moderate heat stress conditions. Will need to monitor the trends in terms of PoP chances/cloud cover as this could lead to slightly lower highs limiting the threat.

One other thing to note will be the potential for rip currents later in the week. An increase in swell periods during the latter part of the week continues to persist in current runs. Latest trends have been around 8 seconds Friday into Saturday. This could lead to an increase risk of rip currents as well as a risk for coastal flooding. This possibility will definitely be worth monitoring through the week before a decision is made.

AVIATION

(12Z TAFS) Issued at 616 AM CDT Tue Jun 2 2026

Areas of fog with VSBYs ranging from 1/2SM-5SM and cloud bases 500-1500 feet, with ALI and VCT on the lower end, will improve to VFR levels by 14-16Z this morning. Isolated showers can be seen on radar over the coastal waters moving inland this morning. Therefore, -SHRA was included in a TEMPO group this morning for CRP and VCT. Scattered showers and thunderstorms are expected to develop along the sea breeze this afternoon, leading to MVFR conditions in and around the convection as it heads west. The convection is not expected to reach COT nor LRD. The activity is forecast to diminish this evening with another round of isolated showers developing along the coast overnight. IFR/MVFR conditions will likely develop once again for ALI and VCT toward early Wednesday morning.

MARINE

Issued at 124 AM CDT Tue Jun 2 2026

Generally light to moderate (BF 2-4) winds will prevail through most of this week. Low to medium (20-50%) shower and thunderstorm chances will persist through the week into the weekend.

FIRE WEATHER

Issued at 124 AM CDT Tue Jun 2 2026

Fire weather concerns are not anticipated through the period as minimum Relative Humidity will increase during the week keeping values around 50% and above. Rain chances will persist through the remainder of the week.
