Area Forecast Discussion
National Weather Service Tulsa OK
336 PM CDT SUN JUL 31 2016

.DISCUSSION...
Dewpoints have remained higher than expected this afternoon, which
has resulted in the need for a heat advisory for parts of
northeast Oklahoma. Some drying of the low level airmass is
expected over the next couple days, resulting in more marginal
conditions for an advisory, so will hold off on any heat headlines
after this evening.

Ioslated showers and thunderstorms are developing this afternoon.
This activity will dissipate by sunset, but will need a pre-first
period mention to cover the ongoing activity. Isolated diurnal
convection will remain possible just about any day this upcoming
week, especially over the favored terrain areas, but coverage will
be to low to include in the forecast at this time.

The main story over the next week will be the heat. An upper ridge
will remain over the center of the country all week. Low level
thermal progs suggest a slow warming trend over the next few days,
which will be aided by the decreasing dewpoints, followed by near
steady-state temperatures late this week through next weekend. The
GFS has backed off on any frontal intrusions next weekend, and
there is no real reason for the decrease in daytime high
temperatures shown by its MOS guidance other than a trend towards
climatology at the longer time ranges. The more steady-state
ECMWF MOS has the right idea.

Stayed close to guidance temperatures the next couple days.
