DISCUSSION...
The extreme heat and high humidity will persist through Saturday
underneath the persistent and strong upper high pressure. A heat
advisory remains in effect for the eastern two-thirds of Oklahoma.
A weak upper short-wave trough in the westerlies is expected to
move through the northeast part of the upper southern plains ridge
and bring a chance for showers and thunderstorms Sunday and
Monday. Initially, a chance will exist in northern Oklahoma closer
to a weak surface boundary on Sunday. Most areas of Oklahoma will
have a chance for rain and thunder Monday before the upper ridge
again builds strongly for the rest of next week. Although
afternoon temperatures will lower slightly Sunday and Monday, a
return to the very hot conditions are expected for the second half
of next week with little to no chance for rain.
