Areas affected...Northwest/Southwest/North-Central
TX...South-Central/Southeast OK

Concerning...Winter mixed precipitation=20

Valid 240729Z - 241130Z

SUMMARY...A mix of freezing rain and sleet is expected to persist
from southwest Texas into north-central Texas and
south-central/southeast Oklahoma throughout the morning.

DISCUSSION...Surface observations around the region currently place
the freezing line from Bonham (in Fannin County TX) southwestward
through northwest Tarrant County before diving more
south-southwestward through San Saba, TX. This orientation puts much
of the DFW Metroplex just above freezing, with some temperatures
actually increasing a degree or two amid light precipitation and
resultant wet bulbing. Even so, continued cold-air advection is
anticipated, with temperatures eventually dropping below freezing
later this morning. Those areas already below freezing will also see
temperatures continue to decrease throughout the morning.

Current regional radar imagery shows some banding across
north-central TX (northwest of the Metroplex), where strong 850mb
warm-air advection is ongoing. Correlation coefficient from KFWS
suggests most of this is sleet. Additionally, a large area of light
precipitation continues to build upstream of the region amid modest
lift attendant to a subtle lead shortwave trough and continued
isentropic ascent. Expectation is for precipitation to continue
across this region for the next several hours, with sleet as the
prominent p-type across southwest/northwest TX and south-central OK.
Freezing rain will likely become more common across north-central TX
over the next hour or two, with another transition to sleet possible
later this morning as the surface continues to cool.
