....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Isolated thunderstorms are possible along the Texas Gulf Coast early
Saturday morning.

....Synopsis...
Strong mid-level western/southwesterly flow is expected to extend
from AZ across the southern Plains and over much of the eastern
CONUS, between a pair of mid-latitude cyclones. The eastern cyclone
will be likely be centered over NY early Friday morning, before then
quickly ejecting northeastward off the Northeast Coast. The western
cyclone is expected to begin the period be centered over western AZ
before gradually move eastward across the Southwest, reaching the
southern High Plains by early Saturday morning.

Surface cyclogenesis is anticipated ahead of this western cyclone,
initiating southerly flow across TX. However, scouring of the
low-level moisture by a preceding frontal passage will limit
moisture return across most of TX. The only exception is over the
immediate coastal areas, where enough moisture and buoyancy may
exists for a few isolated thunderstorm early Saturday morning.
