Day 3 Convective Outlook  
NWS Storm Prediction Center Norman OK
0120 AM CST Thu Jan 07 2021

Valid 091200Z - 101200Z


A few thunderstorms are possible late Saturday night over parts of
central Texas. Severe weather is not expected.

...Synopsis and Discussion...
An upper low will move southeast across the Four Corners and into
northwest TX by Sunday morning, with a cyclonically curved speed max
nosing into west TX by 00Z. Strong height falls will occur over much
of TX overnight, increasing lift.

While very little boundary-layer moisture return will occur ahead of
this system due to a surface ridge over the Gulf of Mexico, forecast
soundings do yield minimal elevated MUCAPE as a southerly low-level
jet increases moisture advection aloft. At least isolated,
non-severe thunderstorms are expected after 09Z roughly along I-35
in TX, but weak instability will limit severe potential.
