Area forecast discussion, Sep 15, 12:42 PM CDT, 2 hours 18 minutes before
Area Forecast Discussion
National Weather Service Norman OK
1242 PM CDT THU SEP 15 2016

.AVIATION.../For the 18z TAFs/
Scattered showers and thunderstorms will form across most of the
area today with the greatest coverage ahead of diminishing
convection across western Oklahoma. Based on latest radar and
satellite trends we have added tempo groups for several sites to
attempt to highly the most likely time that a terminal could be
impacted. Confidence in any of the terminals being impacted is not
particularly high due to the scattered nature of convection. Brief
visibility reductions and ceiling drops can be expected if a
shower or storm passes over. Otherwise VFR conditions are likely.
Some patchy fog may form late tonight but should not be as
widespread as last night and was left out of the TAFs. We will
reevaluate fog potential for subsequent issuances and amend
throughout the afternoon based on convective trends as needed.

.PREV DISCUSSION... /issued 1111 AM CDT THU SEP 15 2016/

DISCUSSION...
Scattered showers and a few thunderstorms have moved into
northwest Oklahoma this morning, with isolated storms
elsewhere. Heating combined with residual boundaries from
ongoing convection should result in at least widely scattered
to scattered showers and storms through late afternoon/early
evening. Reluctant to go higher than chance POPs for the
afternoon as unsure on overall storm coverage.

PREV DISCUSSION... /issued 406 AM CDT THU SEP 15 2016/

DISCUSSION...
A series of small waves aloft will pass through the general
west-southwesterly flow, bringing nearly continuous chances for
rain and thunderstorms through the middle of next week, with a
possible break Monday night. Enhanced chances for rain will occur
Friday and perhaps on Sunday, as stronger waves move through the
southern Plains. Continuously moist lower levels of the atmosphere
will also help support the precipitation.

With the moisture in place and no serious fronts poised to affect
Oklahoma/north Texas, there will also be rather little day-to-day
difference in temperatures, and somewhat less than typical diurnal
variation.

Instability and vertical wind shear will both be relatively weak,
but may be enough to support some marginally severe storms and
heavy rain. The national centers have placed parts of our
forecast area (mainly the western parts) in at least Marginal
Risks (of severe storms/excessive rainfall) over the next three
days.
