and southeast winds mostly under 12 kts.

.PREV DISCUSSION... /issued 313 PM CDT Sun May 20 2018/

DISCUSSION...
Isolated thunderstorms have formed this afternoon near a weak
surface cold front in southeastern Oklahoma. Enough instability
and shear will support a few strong to severe storms, but most the
activity will remain south and east of the forecast area.

Light winds and generally clear skies later tonight may result
in in patchy fog. Perhaps better chances will be across
southwestern Oklahoma and western north Texas, where higher rain
totals were reported last night and early this morning.

A southerly wind will return on Monday and increase during the
afternoon, especially across western Oklahoma.  Shower and thunderstorm
chances will remain rather low, but a few storms will be possible
across southern Oklahoma and north Texas in the afternoon, and
perhaps far western Oklahoma late in the evening.

The overall flow across the southern plains will be rather anemic
this week, so organize severe weather is not expected. A few
afternoon thunderstorms may form during the afternoon or early
evening each day, but overall rain chances will be low.

Late in the work week, a mid-level ridge is expected to build over
the Rockies. This will place Oklahoma and north Texas in north to
northwest flow aloft. There is a chance that somewhat cooler and
drier air may arrive next weekend.
