DISCUSSION

Issued at 1037 PM CDT Mon Jun 8 2026

Tranquil conditions are expected for the rest of tonight with clear to partly cloudy skies and light southeasterly winds. The low temperatures overnight into early Tuesday morning will be in the lower to mid 70s for most inland areas and the upper 70s to lower 80s for the Houston Metro area and coastal locations.

There will be two features that will allow us to remain closer to drier conditions rather than the active weather pattern we had experienced last week. The first one is a board mid-level high pressure meandering over Texas and Louisiana. The second one is an upper-level high pressure anchored over the Mexico region. Both of these will help limit rain development through at least the end of the work week. Now, we will still have sufficient moisture, diurnal heating, and instability for a few showers and thunderstorms to be able to develop, particularly along and near the seabreeze during the afternoon to early evening hours. We might also see some streamer showers move into our coastal locations in the mornings.

And...It's summer in Houston! So we will likely see the typical pattern of hot days and warm nights. Look for highs peaking in the lower 90s for most inland portions and the upper 80s to lower 90s along the coasts and lows in the mid to upper 70s inland and upper 70s to lower 80s along the coasts. We will have increased heat risk this week as heat indices peak in the lower 100s for most of Southeast Texas through the upcoming weekend. Continue to practice heat safety to protect yourself, loved ones, and pets from the heat. If you plan to spend time or work outdoors, make sure to take breaks from the heat/sun often, drink plenty of water, and wear appropriate clothing. Never leave children, vulnerable adults, or pets unattended in a vehicle.
