.DISCUSSION...
Surface high pressure was centered across Eastern Oklahoma to
Southern Illinois this afternoon. Underneath the high...clear
skies and light/variable winds were common across Eastern
Oklahoma and Northwest Arkansas.

Overnight tonight...light winds and mostly clear skies are
expected to continue as the surface high begins to shift eastward.
These conditions will again aid in temps getting down into the mid
30s to mid 40s for much of the CWA. The cold spots tonight look
to be over parts of Northwest Arkansas as they remain on the
westward side of the high pressure center. In response...some
valley locations could see temperatures dip down close to the
freezing mark along with patchy areas of frost. Will hold off on
any frost/freeze headlines for now due to the isolated/patchy
possible coverage.

Southerly winds return to the CWA Tuesday and Wednesday and
become breezy Thursday and Friday as an upper level ridge develops
over the Central U.S. At the same time...a slow warming trend is
forecast to begin Tuesday and continue through the week with
possible highs back in the upper 70s/low 80s by Friday.

In the extended forecast...latest model solutions continue to
agree with a wave moving onto the West Coast Thursday night/Friday
and into the Plains over the weekend. Most recent model runs have
begun to indicate the potential for an upper level impulse to
eject into the Southern Plains Friday/Saturday ahead of the main
approaching wave. For now will hold off on introducing pops to the
forecast for Friday to see if indications continue to show up in
later model runs...and will continue with small pops Saturday
ahead of the approaching waves associated cold front. Also ahead
of the approaching cold front...gusty southerly winds are forecast
Friday and Saturday.

Showers and thunderstorms become likely Saturday night for the CWA
as model consensus continues to forecast the cold front across the
region Saturday night into Sunday. As of this forecast...with the
timing of the boundary to be during the overnight/morning
hours...overall severe potentials could be limited. Thunderstorm
potentials look to weaken behind the front and could exit the CWA
Sunday morning with perhaps some rain chances continuing into
Sunday...kind of how the front/precip developed this past weekend.
Will continue to monitor latest data as this forecast will likely
change and will be updated through the week.
