.DISCUSSION...
A more active weather pattern will begin to influence the
southern Plains over the next 7-10 days.

The first trough/upper low will approach our area today into
tonight and will move across Oklahoma on Friday.  As a result,
strong southerly winds can be expected today into tonight.
Frequent wind gusts over 40 mph (plus) are likely, especially
along and west of Interstate 40. A Wind Advisory will be issued
for this area. Strong wind gusts may last well into the overnight
period, but for now will run the advisory through midnight. Rather
strong winds are expected again on Friday, but will not issue a
wind advisory at this time. The focus will shift to fire weather
conditions and the chance of severe storms on Friday.

Strong to severe storms will also be possible this evening into
the overnight, mainly across western Oklahoma. Better chances of
severe weather will be across the Panhandles from late afternoon
through late evening. Instability will decrease during the
evening, so storm intensity and coverage should decrease as
thunderstorms enter western Oklahoma.

Much drier air will enter western Oklahoma and western north Texas
early Friday behind a dryline/cold front. Models differ on how
quickly the dry air moves east and how dry the air will be. There
is enough of a chance for rather dry air, humidity at or below 20
percent, to be in place with rather strong winds (gusts over 40
mph). A Fire Weather Watch will be issue for: western north
Texas, southwest Oklahoma, and parts of central/ north central
Oklahoma.

Severe thunderstorms will also be possible Friday afternoon,
especially across southeast/eastern Oklahoma.

Shortwave ridging Saturday will bring a period of quiet weather
before another trough approaches the area on Sunday. How much
moisture will return ahead of this system is somewhat uncertain.
However, enough instability will be present for a risk of severe
storms Sunday afternoon/early evening.

Another trough will begin to influence our weather around Tuesday
and Wednesday of next week.
