Area Forecast Discussion
National Weather Service Norman OK
545 PM CDT Thu Jun 22 2017

.AVIATION...
Should see VFR conditions continue through much of the forecast
period. A cold front will move south across the area late tonight
and through the day on Friday. Have introduced chances of TSRA at
most sites for a period of time after the frontal passage. We could
also see some MVFR conditions behind the front and associated with
the convection.

.PREV DISCUSSION... /ISSUED 341 PM CDT Thu Jun 22 2017/

.DISCUSSION...
Except for some cloudiness, the effects of Tropical Depression
Cindy should remain southeast and east of the area with its
influence decreasing tonight and tomorrow as the remnant
circulation moves up toward the central Mississippi valley.
Attention for us is to our northwest where a front currently in
western Kansas and eastern Colorado will move toward the area.
Storms are expected to form near the front and in the developing
upslope flow behind the front. Although some of these initial
storms may weaken as they approach the area tonight, the signal is
stronger (at least in the GFS and ECMWF) of storm redevelopment
tomorrow near and north of the front when we should see at least
scattered showers and storms. The front will also bring noticeably
cooler air into the northern/central part of the area. Depending
on the cloud cover, southern Oklahoma and north Texas will likely
be quite warm again tomorrow with forecast heat index values
pushing advisory level. Will not issue an advisory with this
package given a little uncertainty on cloud cover and dewpoint
values, but regardless, it will be hot.

This front makes a good push to our south by late June standards
taking the edge off of the high temperatures for a few days. We
remain under northwesterly flow aloft and continue with some
chances of precipitation with both the moisture return from the
south and the possibility of convection moving off the High
Plains toward the area.
