.DISCUSSION...
Issued at 1211 PM CDT Sat May 30 2026

Dry and warm conditions are expected to continue this weekend
as the as the mid to upper level ridge over East TX and LA
continues to dominate the local weather pattern. Expect sunny to
partly cloudy skies along with south to southeast winds at
around 5 mph. As stated in the past few days, conditions will be
warmer through early next week with high temperatures in the lower
90s for much of the inland portions and the upper 80s along the
coast. Heat indices are expected to peak in the upper 90s to lower
100s through early next week. Thus, it is recommended to be
proactive and be prepared for the heat if you plan to work or
spend time outdoors these next few days. Drink plenty of water,
take several breaks from the heat/sun, and wear appropriate
clothing. Warm nights are also expected with lows rising into the
mid 70s for many inland locations and the upper 70s to lower 80s
along the coast. We might have high temperatures lower back into
the upper 80s closer to the mid-end of the next week.

Models have "backed off" on the rain chances for Sunday night and
Monday since we would still be influenced by the mid level ridge.
We now have drier conditions for Sunday, and have isolated to
scattered showers and thunderstorms on Monday, mainly for areas
near and south of I-10. These will more likely be those afternoon
storms we typically see on a hot summer day ;). Rain chances ebb
in the evening as diurnal heating decreases.

Although weak disturbances are expected to pass through throughout
the rest of the week, it is not known how much of the ridge will
affect our local rain development. For now, it seems that we will
have a rinse and repeat pattern of a few showers over the waters
and coastal location during the nighttime to morning hours,
followed by an increase in showers and thunderstorms during the
afternoon to early evening hours as diurnal heating and
instability increases. Smells like summer!
