.PREV DISCUSSION... /ISSUED 1031 AM CST Tue Jan 19 2021/

...Eastern/central Texas...
Showers persist at midday along the cool side of a surface front,
with a low but non-zero potential for lightning within a marginally
supportive environment. Additional development should occur
southwestward over time into other parts of south-central Texas,
although thermodynamic profiles appear rather marginal for charge
separation and thunder probabilities should remain minimal. 

...Far southern California/southwest Arizona...
A closed upper low will continue to transition south-southwestward
toward off the Baja coast through tonight. Related steep mid-level
lapse rates and forcing for ascent may support isolated
thunderstorms, although most of this activity should tend to be
focused offshore and/or across northwest Mexico.
