National Weather Service Tulsa OK
312 AM CDT FRI JUL 15 2016

.DISCUSSION...
Showers and thunderstorms have developed this morning across
far northern Oklahoma and northwest Arkansas in the vicinity
of the 850 mb boundary. Meanwhile, an MCS was moving to the
east-southeast across south-central Oklahoma. Both of these features
will affect the area this morning. Additional showers and thunderstorms
are expected to develop this afternoon in the vicinity of outflow
boundaries left over from the morning convection. Some of the thunderstorms
today could be strong to severe with strong gusty winds the main
concern. However, do not expect anything the magnitude of what occurred
on Thursday.

Another thunderstorm complex could affect the area again Tonight
and on Saturday. Saturday will be the last day that we see near
normal temperatures for a while. A large ridge of high pressure is
set to build across the central United states from Sunday well into
next week. Heat headlines will more than likely be needed for a
good chunk of next week across portions of eastern Oklahoma and
western Arkansas.
