.PREV DISCUSSION... /Issued 1008 AM CST Tue Feb 21 2017/

DISCUSSION...
Updates to this point have centered around trimming dense fog advisory
and adjusting weather grids accordingly. Fog continues to persist across
parts of eastern Oklahoma...so have extended the advisory through noon.
Otherwise...will leave remaining elements pretty much as they for now as
less sky cover/fog trends continue...albeit at a little slower
pace than first anticipated.

For now...updates will occur as headlines/fog mentions are
removed.
