Houston residents can expect to wake up to patchy fog and experience near record heat during the holiday week, with a Dense Fog Advisory affecting the Gulf Coast region, particularly in the mornings. Click2Houston reports that despite a few isolated showers, temperatures are likely to reach the high 70s, and there’s potential for a fourth consecutive day of record-tying highs.

The area is under the sway of a robust high-pressure system that's been funneling in moisture from the Gulf, but it's not allowing any cooler air to displace the warmth, so residents may want to hold off on the heavy sweaters and instead opt for lighter attire during this unseasonably warm Christmas period. According to the National Weather Service, apart from the foggy mornings, the forecast anticipates mostly cloudy to partly sunny days throughout the week with overnight lows in the mid to upper 60s and highs possibly pushing 80 on Christmas Day.

As for the holiday itself, locals can expect "We’re in store for one of the warmest Christmas’ that we’ve seen in quite some time! Afternoons will be pushing close to 80 each day after foggy mornings" on record, according to Click2Houston, with the chance that the temperature could tip 80 degrees, potentially tying for the third warmest Christmas ever noted. The typical holiday chill is notably missing, leaving behind a Houston that seems more suited to shorts and flip-flops than to scarves and mittens.

Warm and foggy conditions are expected to continue through late December, with patchy fog possible across the area. Forecasters said a change in the weather is not expected until next Monday, when a cold front could bring cooler air to the region. Additional updates will be provided as conditions develop.
