Valid 141200Z - 151200Z

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

....SUMMARY...
Severe thunderstorms are not forecast through tonight across the
contiguous United States.

....Synopsis...
A mid-level low will move eastward across northern NM and into the
TX Panhandle during the period.  An associated cold pocket,
featuring 500 mb temperatures in the -22 to -24 deg C range, will
overspread areas from west to east across the I-40 corridor in NM
and TX.  Ascent via the disturbance and cold mid levels will support
sporadic isolated thunderstorm activity.  Relatively cool/stable low
levels and limited instability will preclude strong thunderstorm
development across the area centered on the southern High Plains
today through tonight.  Elsewhere, a 1040 mb surface high over the
OH Valley/southern Appalachians will lead to tranquil conditions for
much of the East/Southeast U.S.  A few thunderstorms may occur over
the FL Keys and near the beaches of South FL, as well as Deep South
TX in the vicinity of a remnant frontal zone.
