Tonight’s cold front will bring a shift in winds and a chance of fog to southeast Austin, but the weekend’s temperatures will stay mild.
Cold Front and Wind Shift
A cold front is moving through the area overnight into early Sunday morning. The wind will shift first to the northwest and then to the north as the front passes. Although the winds will be brisk, they will actually be less windy on Sunday than they were on Saturday.
Fog Advisory and Overnight Low Temperatures
Ahead of the front, some low clouds and areas of fog are possible. Overnight lows are expected to drop into the upper 40s and low 50s. A Fog Advisory has been issued for some areas southeast of Austin, where locally low visibility will be possible through Sunday at 6 a.m. The advisory is extended as a Dense Fog Advisory through Sunday at 9 a.m.
Sunday Outlook: Clouds, Sun, and Warmth
Behind the front, sunshine will mix with scattered clouds on Sunday. A small area of low pressure-known as a meso-low-just northeast of Austin will keep some clouds in the vicinity. Clouds will be present east and north of the city. While it will be cooler on Sunday, highs will still range from the 60s where the clouds hang around to the low 70s in sunnier areas.
Winter Solstice and Daylight
Sunday at 9:03 a.m. marks the Winter Solstice and Austin’s shortest day of the year, with only 10 hours and 11 minutes of daylight. The city will slowly start gaining some of that time back beginning Monday.
Early Week Weather Pattern
Beginning Monday, the pattern will shift to clouds to sun. An increase in humidity will bring back the muggy air to Central Texas. The extra humidity will mean morning clouds each day that will very slowly give way to increasing sun each afternoon. The earlier the sun comes out, the closer to 80º we’ll be. Most days of the coming Christmas week will at least reach the 70s.
Christmas Week and Beyond
Highs for the next seven days are projected to remain in the 70s. Christmas Day should push into the upper 70s once the morning clouds lift away. The final days of the year appear wetter according to some of our long-term computer guidance. We need rain and we’ll take whatever we can get, but no signs of significant cold anytime soon.
End of 2025 Outlook
The Winter Weather Outlook for 2025 suggests that the final days of the year will be wetter. The guidance indicates that rain will be present, but there is no indication of a significant cold front arriving in the near future.
