.DISCUSSION...
Drier air associated surface high pressure continued to spread
southeastward across the Central and Southern Plains this
afternoon. Ahead of the approaching surface high...breezy
northerly winds along with mostly clear skies were common across
the majority of Eastern Oklahoma and Northwest Arkansas. Some
scattered cloud cover remained over far Southeast Oklahoma as the
departing shortwave trof axis had not completely cleared the
region.

This evening and overnight tonight...surface high pressure will
set up over the CWA with clear skies and winds becoming light.
These conditions combined with the drier air filtering into the
region will aid forecast temperatures overnight to fall into the
mid 30s to low 40s north of Interstate 40 and around 40 degrees
to the mid 40s south of Interstate 40. Locations in far Northeast
Oklahoma and far Northwest Arkansas that dip down into the mid 30s
could observe some isolated to patchy areas of a light frost
early morning Monday. With the isolated coverage of frost
potential will hold off the frost advisory for now.

Cool temperatures and light winds are forecast to remain over the
CWA Monday before the surface high begins to shift eastward
Monday night and southerly winds return Tuesday. This will allow
for a slow warming trend to develop through the work week and into
next weekend. An upper level ridge of high pressure looks to
develop over the Central U.S. late in the week with breezy
southerly winds Friday and Saturday and highs back in the upper
70s/low 80s possible.

At the far end of the extended forecast...latest model solutions
continue to indicate a wave moving onto the West Coast Friday and
into the Plains over the weekend. This looks to be the next
chance for showers and thunderstorms across the CWA as a cold
front looks to push through the region toward the end of next
weekend.
