KEY MESSAGES

- Extreme Cold Warning for all of south central Texas has been extended until 9 AM CST Tuesday morning. Another hard freeze in store tonight into Tuesday morning.

- A slow warming trend through Thursday, with another cold front expected Friday.

SHORT TERM

(Tonight through Tuesday night) Issued at 148 PM CST Mon Jan 26 2026

Afternoon visible satellite imagery shows clear skies across most of south central Texas, with some low clouds noted over the coastal plains and across portions of the southern Edwards Plateau and western Hill Country. Looking farther north and west, the clear skies show quite an extensive area of ice and snow across much of western and north Texas. Northerly winds will continue this afternoon with temperatures struggling to reach freezing across the Hill Country eastward into the I-35 corridor near and north of Austin. Highs should top out in the lower 30s to lower 40s elsewhere.

A 1040mb surface high will continue to build southward into the region overnight. Skies should remain mostly clear, except for some thin, high clouds moving in from the west. Conditions appear favorable for good radiational cooling and will lean toward the lower side of guidance with respect to overnight low temperatures. This should keep most areas in the teens to near 20 degrees along the Rio Grande. We do expect to see some single digit readings, mainly in the wind-protected valleys over the Hill Country. All areas will see highs above freezing on Tuesday as southerly winds in the lower levels return. We do expect to see an increase in mid and high level clouds, especially north of Hwy. 90 and have opted to keep temperatures a little lower than guidance here. Highs on Tuesday should range from the lower 40s to lower 50s. Another widespread freeze is in store Tuesday night into Wednesday morning with lows mainly in the 20s.

LONG TERM

(Wednesday through next Monday) Issued at 148 PM CST Mon Jan 26 2026

A weak cold front moves in from the north Wednesday morning. Despite the passage of this front, temperatures should still manage to warm into the upper 40s and 50s during the afternoon hours. The warming trend continues into Thursday with zonal flow aloft over the region. Highs on Thursday will finally warm to near climatological levels for this time of year. This will likely be the warmest day of the forecast period, with mid 50s to mid 60s expected. The zonal flow aloft becomes northwesterly by the end of the work week. This along with an upper trough moving through the Midwest will allow another cold front to move in late Thursday into early Friday. As the front pushes into the region, we could see a few showers develop for areas east of the Interstate 35/Interstate 37 corridors. The general consensus over the last few days continues to show a decreasing chance for precipitation with this next front. We will keep rain chances low (20-30%) and any rainfall amounts should stay under one-tenth of an inch.

Temperatures trend below normal Friday through the weekend with surface high pressure in control of our weather pattern. We should see another warming trend take place toward early next week.
