DISCUSSION

Issued at 1220 PM CDT Thu Oct 8 2026

Very little changes from previous forecasts. Mostly dry conditions are expected over land with low to medium rain chances over the Gulf waters through Friday as Tropical Storm Isaias moves away from the region. Although we will not get any direct impacts from Isaias, long period swells are expected through the end of the week are expected to interact with Ekman Transport to promote coastal flooding. Apart from the coastal flooding, high risk of rip currents will also be expected.

Warm temperatures will return with highs in the 90s through the week into next week. Thankfully, moisture levels will be low enough to keep the heat index in check through the weekend. Moisture will increase next week with heat index values over 105 degrees returning along with a moderate to major risk of heat-related impacts Monday. Please remember to continue to practice heat safety: take breaks when outside, drink plenty of water, and look before you lock.
