...UPDATE...

.DISCUSSION...
Low level ceilings remained in place across the northeast corner
of Oklahoma and also much of Northwest Arkansas this evening...
while mostly clear conditions were observed over the rest of
Eastern Oklahoma. Also...winds had become light varying from
north to east underneath building surface high pressure in the
wake of a frontal boundary that moved through the region today.

Overnight tonight...the low level ceilings look to possibly lift
northeastward slightly before filling back in over much of
Northeast Oklahoma and Northwest Arkansas as surface high pressure
moves through the Plains. Additional cloud cover looks to develop
out west and begin to spread into the region ahead of the next
approaching upper level low...currently diving southeast into the
Desert Southwest.

Slightly lower dewpoints within the weak north to easterly low
level flow should allow for cooler low temperatures in the low 40s
to low 50s from north to south tonight. These temperatures
combined with calm/light winds and relative humidity values near
100 percent underneath high pressure could create areas of patchy
fog to develop over parts of Northeast Oklahoma and Northwest
Arkansas late tonight into Tuesday morning. Thus...for the evening
update have added a mention of patchy fog for these locations as
well as added a few minor tweaks to sky/temp/dewpoint/wind grids
based on current trends and conditions. The rest of the forecast
seem to be handling well at this time.
