A warm weekend but a cold front is on the way

HOUSTON, Texas (KTRK) -- We're in store for a weekend full of sea fog, warm temperatures, and humid air.

After a mild start this morning, temperatures will gradually warm in to the low 80s this afternoon. Mostly cloudy to overcast skies will hold all day, but rain chances will remain isolated.

How is the rest of the weekend shaping up?
Clouds and sea fog will continue Saturday night and Sunday as the humid air continues to blow in from the Gulf of Mexico. That means you can expect lows around 70 and highs in the low 80s for Sunday. A few showers are also possible Sunday ahead of our next cold front arriving Monday, especially farther north.

How cold will it get behind Monday's front?
Monday's cold front is a weak one, and it will only drop lows into the 50s. A stronger push of cold air will blow in Tuesday, dropping lows back into the low 40s Wednesday. There are currently no freezes in our forecast over the next 10 days.

Why is the sea fog persisting for so long?
Last week's severe cold snap cooled off the shelf water temperatures into the 50s, which is anywhere from 10-20 degrees below normal. When humid Gulf air blows over the top of these chilled waters, the moisture condenses out of the air to form the fog. The colder the water, the more dense the fog gets and the longer it lingers. The sea fog is likely to linger all the way through the weekend as it will take some time for the cold shelf waters to warm up and stop making the fog. The only other way it can move out is if a front can blow in and push the moisture back out into the Gulf. The earliest that could happen is Monday.

When will see abundant sunshine again?
This dreary pattern will persist all the way into Tuesday. Abundant sunshine isn't likely to return until Wednesday of next week when a stronger cold front is expected to push the clouds out into the Gulf and blow in drier air.
