.SHORT TERM...
(Today through Thursday)
Issued at 208 AM CST Wed Jan 22 2025
Key Messages:
- Some residual moisture on roadways may have refrozen into black
ice this morning. Use caution if traveling through this morning
- Cold Weather Advisory in effect through this morning with
hazardous temperatures and wind chill values. Protect People, Pets,
Plants, and Pipes from the cold weather
The Cold Weather Advisory continues through noon today these
bitterly cold conditions. Additionally, with freezing temperatures
overnight, any residual moisture will be frozen and could lead to
patchy black ice on roads and concrete. Use caution through
Wednesday morning if venturing out.
Highs will rise into the upper 40s to mid 50s Wednesday afternoon
under mostly clear skies. Cloud cover increases Wednesday night and
another weak cold front moves across the area overnight. Forecast
lows are in the mid and upper 20s, so another hard freeze is
anticipated for all but the urban centers of Austin and San Antonio
and over southwest counties where a light freeze is expected. Wind
chills will be in the teens and 20s but look to stay above Cold
Weather Advisory criteria at this time. A reinforcing cold front
arrives before daybreak Thursday, but not significant changes in
winds or day-to-day high temperatures are projected from this
feature.

.LONG TERM...
(Thursday night through Tuesday)
Issued at 208 AM CST Wed Jan 22 2025
Key Messages...
- Hard freeze Thursday night into Friday morning
- Clouds and warmer temperatures return over the weekend with low
chances for showers
- Weak cold front early next week
Clear skies, dry air, and light winds will allow for one more hard
freeze Thursday night into Friday morning. Low temperatures in the
20s are forecast for most of the area. A southerly flow resumes on
Friday and strengthens Saturday, with dew points and low level
moisture modifying quickly Saturday. The weekend looks to remain
mostly cloudy to cloudy across most of the area, except the Rio
Grande, with low level warm air advection contributing to some weak
showers across central and eastern areas late Saturday into Sunday
beneath a weak cap. A shallow, weak cold front is forecast to
move into the northern areas Sunday morning, however there is low
confidence on how far south the front and modified polar air makes it
Sunday, given the upper level low forecast to over California and
west to southwest flow aloft across Texas. Nonetheless, a second
surge from the north should help push the front through the area
Monday, with cooler conditions behind it, but continued cloudy
conditions and rain chances given the pattern aloft.
