1AM Day 3 Convective Outlook for Friday, January 23. NO SEVERE THUNDERSTORM AREAS FORECAST
SUMMARY
Isolated thunderstorms are possible across parts of Texas on Friday.
Synopsis
An upper shortwave trough offshore southern CA and northern Baja will quickly eject east to northwest Mexico and the Southwest on Friday/Friday night. This will result in increasing southwesterly mid/upper flow across the southern Plains as an arctic cold front plunges southward across TX. Modest Gulf moisture will be in place ahead of the front across portions of southern TX and the TX Coastal Plain. As temperatures aloft cool and warm advection in the midlevels overspreads the southward-advancing cold front, isolated thunderstorms will be possible. A few lightning flashes could even accompany winter precipitation as the arctic airmass begins to filter southward through the period. Severe storms are not expected.
