FORECAST HIGHLIGHTS

  • MILD TODAY, TOMORROW: Temperatures will reach the 60s
  • COLD FRONT SATURDAY: Becoming windy, cold by Sunday morning
  • HARD FREEZE MONDAY MORNING: Lows in the mid-20s
  • WINTRY PRECIP?: Small window Monday night; any precipitation would be light

FORECAST

Good morning! We’ll see a cool morning, but a mild afternoon. Expect highs in the mid-60s today, with partly cloudy skies. All in all, a beautiful day! That’ll be the case tomorrow, too.

COLD FRONT SATURDAY

A strong cold front will sweep through by Saturday morning. The cold air will lag behind the front a bit, meaning the cold will really settle in by Sunday. So for Saturday, expect a windy, cooler day. However, we’ll spend most of Sunday in the 40s, despite sunny skies. Wind chills will likely be in the 30s.

MONDAY’S MLK MARCH

Clear skies Monday morning means we’ll see a significant freeze for San Antonio. Lows will dip into the mid-20s. Once the march gets underway, temperatures will “warm” to the low-30s. Wind chills are forecast to be in the 20s. The sun is forecast to be out for the first half of the day, however, clouds are expected to roll in by the afternoon.

WINTRY MIX UPDATE

Moisture is going to be hard to come by, meaning chances remain low. But, a passing disturbance combined with an area of low pressure along the coast could throw a bit of precipitation in our direction Monday night. With that said, anything we’d see would be very light and the window will be small. Any precipitation would move east by Tuesday morning and currently, impacts, if any, would be minimal.
