...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.
