.DISCUSSION...
Cold front has just moved south of I-20, with nw winds gusting
near 20 kts in its wake. The timing of this front and resulting
isobars indicate that for all but southern portions of the area,
nw-n winds will be stronger in aftn than morning. As this pressure
gradient relaxes, winds will quickly decouple for most of the area
overnight, except where pressure gradients are noted to the west
with possibly a lgt southerly breeze over ne TX before daybreak.
No clouds expected with this very dry airmass and the same may be
the case with another weaker front pushing into the area Thursday.
Finally, the front on Saturday in his quick succession of
boundaries will see increased uppr lvl air with top down moisture
quickly deepening thru the mid lvls. Some thunder may be noted
with this rain although weak low lvl lapse rates may be the
limiting factor. Model runs seem to be pushing this possible rain
event until later into the wknd. Biggest concern is low humidities
and gusty winds associated with the frqt frontal passage with the
worsening ongoing drought./07/
