Mesoscale Discussion 0123
NWS Storm Prediction Center Norman OK
1135 AM CST Wed Feb 01 2023

Areas affected...north-central Texas...northwest Texas...and
portions of Southwest Texas

Concerning...Freezing rain=20

Valid 011735Z - 012130Z

SUMMARY...Light to moderate freezing rain will persist into the
afternoon from north-central Texas to near Abilene and east of
Midland.

DISCUSSION...A band of relatively concentrated precipitation has
developed from west of San Angelo to northern Texas. This is forming
in a zone of weak frontogenesis and warm air advection around 700mb.
This will favor heavier precipitation rates in this corridor through
the afternoon. The heaviest rates are expected by late afternoon as
frontogenesis strengthens and focuses in this region. The last
several HRRR runs suggest a mesoscale corridor of total QPF in
excess of 0.75 inches. Observations this morning have shown a mix of
sleet and freezing rain, but this is expected to transition to
mostly freezing rain this afternoon as the cold air becomes more
shallow. Icing is expected across most of this region with more
significant icing possible where any banding can develop later this
afternoon/evening.
