12AM Day 2 Convective Outlook for Friday, January 23. NO SEVERE THUNDERSTORM AREAS FORECAST
SUMMARY
Isolated weak thunderstorm activity is possible Friday afternoon into Friday night across parts of central Texas.
Synopsis
An upper low and attendant shortwave trough off the southern CA/northern Baja coasts Friday morning will develop east toward northwest Mexico and lower CO Valley by Saturday morning. As this occurs, increasing midlevel moisture will spread northeast across the southern Plains as an arctic cold front dives southward across OK/TX. As forcing for ascent increases Friday afternoon into the overnight hours, mainly wintry precipitation is expected across OK and the northern half of TX. Near and to the south of the arctic cold front, sufficient low-level moisture will be in place to support modest instability, especially as midlevel temperatures cool. This could result in isolated thunderstorms near the southward-surging cold front, or within the transition zone just to the cool side of the boundary where sleet and freezing rain are possible.
