...UPDATE...

.AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.

MVFR and possibly, IFR ceilings will be possible mid to late
morning, associated with expanding stratus deck currently located
in North Texas. MLC and FSM will be most likely to see these
ceilings, with FEW to SCT coverage expected at the remaining
terminals. Ceilings will lift early afternoon, with SCT cu for the
rest of the afternoon hours. Fog potential at the AR terminals is
nonzero late in the period but is currently below mentionable
levels.

DISCUSSION...
Flow aloft will continue to become more amplified over the CONUS
with deep troughing west and upper ridging east. This will
maintain dry and unseasonably warm conditions across the region
with a slight decrease in both temps and dewpoints into early next
week. The aforementioned trough will slowly slide eastward and aid
in pushing a cold front across the forecast area Mon night -
Tuesday. The primary forcing associated with the passing trough is
likely to pass quickly to our north, with overall rain totals also
expected to reflect higher amounts across portions of NE OK and
decreasing further south and eastward. Post frontal temps for mid
to late next week are expected to be nearer seasonal normals.
