Thunderstorms possible this weekend, major cool down next week

HOUSTON, Texas (KTRK) — Our foggy, humid, and warm weather is going nowhere until a strong cold front arrives next week.

A heat ridge parked over the Gulf of Mexico will keep our highs and lows running about 20 degrees above average, challenging record highs on Saturday. Houston’s average high for this time of year is 67 and the average low is 47.

We’re forecasting lows in the 60s and highs well into the 70s this weekend.

We’re off to another foggy and unseasonably warm start to our Saturday.

How long will the sea fog stick around?

Sea fog will continue to be an issue off and on through Tuesday of next week. A storm front will try to push into Southeast Texas Saturday night, which should push the sea fog back into the Gulf briefly on Sunday. Otherwise, we’ll have to wait until a stronger cold front arrives late Tuesday to push the fog away. Until then, the density of the sea fog will depend on how strong the winds blow. Winds below 10 mph will support dense fog while winds above that will improve the visibility.

What can we expect for our weekend weather?

It will be unseasonably warm and humid again on Saturday with another round of morning fog. A few showers are possible during the day ahead of the storm front that will bring the chance for a round of thunderstorms late Saturday night and Sunday morning. The rain should be mostly south of Houston by noon. There won’t be much of a temperature drop behind the storms, so expect lows in 60s and highs in the 70s.

How cold will it get behind the stronger cold front next week?

The cold front arriving next Tuesday night has the potential to drop highs into the 50s and with lows in the 30s. It will mark a pattern change that could bring chilly weather all the way to Christmas Day.
