Juneteenth brings more extreme steam plus a small chance of strong storms

HOUSTON, Texas (KTRK) -- Tropical Storm Arthur left behind some extreme steam over Southeast Texas, and we are certainly feeling it today with heat index values peaking between 110-120 across Southeast Texas.

An Extreme Heat Warning continues until 8 p.m. for all of Southeast Texas, then it converts into a Heat Advisory for Juneteenth.

Temperatures overnight will likely stay above the 80 degree mark for most us due to all the steamy air and the wet ground. It won't get as hot on Friday as it did Thursday, but heat index levels will still peak between 105-110. Actual high temperatures will top out in the low 90s. Be sure to stay well hydrated and take lots of breaks in the shade if you'll be outside for long stretches of time during the heat of the day.

Late in the day there is a 40% chance of scattered thunderstorms popping up in the steamy air, especially north of I-10. That's because a weak front will approach from the north. Some of these storms could be strong with wind gusts over 50 mph, so an isolated severe thunderstorm is possible. Heavy rain could also briefly flood streets. Our coastal counties are the least likely to get any rain, so it should be a fine day at the beach for a Juneteenth celebration.

How does the weather look for Saturday and Father's Day?

Scattered thunderstorms are predicted for Saturday with what's left of the front still stalled out nearby plus a weak upper air disturbance spinning overhead. Your chance of getting measurable rain is at 60%. Highs should only peak in the upper 80s due to the widespread clouds and rain-cooled air those storms will spread through Southeast Texas. For Father's Day, moisture levels will be dropping, so there's only a 30% chance of a shower or thunderstorms. With less clouds and more sunshine, highs will again heat up into the low 90s.
