Record breaking heat Thursday but a slight chance of rain Friday

HOUSTON, Texas (KTRK) — Get ready for another dangerously hot afternoon in SE Texas as temperatures soar to 100+. Heat index values are expected to hit 108 which is why the NWS has issued an areawide Heat Advisory until 8 pm Thursday.

Keep taking all necessary precautions if you work outdoors by staying hydrated and taking breaks indoors or in the shade.

Thursday afternoon-evening, a stray shower or storm may pop up as an upper air disturbance approaches from North Texas. This disturbance will bring a slightly better chance for rain on Friday and might just keep our high temperature below 100 for a day.

What do our rain chances look like with this disturbance?
Right now we think about 30%. The disturbance rotating around the heat ridge should combine with Gulf moisture in the afternoon to produce a few thunderstorms. The disturbance is gone on Saturday, but enough moisture remains to give us a 20% chance for measurable rain.

How about those rain chances for next week?
While record highs will continue to be challenged through Monday, the rest of next week will feature a 20%-30% chance for afternoon downpours. The heat ridge will slide to our north and allow a moist easterly flow to send weak disturbances our way.

Is there anything worth watching in the tropics?
