KHGX Radar.
A Heat Advisory remains in effect for peak heat index readings between 106°-112°F until 7 PM Saturday. This advisory may need to be extended into the weekend.
Isolated storms are possible late this afternoon into the evening. These storms would be moving in from the northeast, but they are expected to gradually dissipate as they move into our area. Conditions favorable for a few strong to severe storms, mainly across our northeastern counties. The main hazard is damaging wind gusts. Slight Risk (level 2 of 5) of severe weather for far eastern portions of Trinity, Polk, and Houston Counties. Marginal Risk (level 1 of 5) of severe weather generally east of a Madisonville-Huntsville-Liberty line. Remain weather-aware and stay tuned for forecast updates! Have multiple ways to receive warnings!
Hot weather is to continue on Friday with highs in the 90s to triple digits. Heat indices will range from 106-112 degrees. With these hot conditions, remember to stay hydrated and take breaks indoors to cool off. Isolated to scattered showers and thunderstorms will be possible in the afternoon, with the best chances north of I-10.
Warm and muggy again tonight with lows from the upper 70s to low 80s. Some clouds and/or patchy fog possible near sunrise, particularly for areas west of I-45.
Hot and humid conditions continue with high temperatures mostly in the 90s to triple digits. Max Heat indices are expected to reach 100-113 degrees. Isolated to scattered showers and storms are possible this weekend, with the best chances north of I-10. Please practice heat safety by checking on the elderly, children, and pets, staying cool and hydrated, and wearing light-weight, light-colored clothing.
Save the date for the Partial Lunar Eclipse, happening on August 27-28! You will be able to view the eclipse right here in SE TX with your own eyes, no eclipse glasses needed :) Look for the bright and shadowed parts of the moon, along with a copper/orange tint 🌕🌖🌗🌘
