.DISCUSSION...
A quiet night overnight with convection generally staying north
and south of the area as upper level wave moves into the Great Lakes
region. Today will be relatively quiet, however, there will be
the possibility of isolated to scattered convection generally
along and north of the Interstate 40 corridor. Lapse rates will
steepen through the early afternoon hours and we should see some
isolated/scattered convection break out by mid to late afternoon.
Weak winds aloft should prevent anything from becoming organized
and gusty to strong winds would be the only concern.

Heat returns this weekend with temperatures becoming more August-
like. Highs will climb into the 90s both today and tomorrow, and
combined with dewpoints in the 70s, could see heat indices of 100
to 105 degree range...especially later today.

We finally get a broad, low amplitude ridge building over the
Southern Plains through early this upcoming week before the near
zonal flow pattern is interrupted by a northern stream wave
dropping down into the plains. The attendant cold front will
approach by midweek bringing with it an increased chances for
showers and thunderstorms. Cooler and drier northwest flow pattern
looks to round out the week.
