latest guidance continues to back off on their development.
Current probabilities of seeing IFR/LIFR cigs are around 20%. If
low clouds do develop, the best chances are between 12Z-20Z.
Terminals that continue to see NE winds may remain well mixed
and unable to fully fog in. However, locations with light to
calm winds may see shallow fog develop and it is expected to mix
out rather quickly Saturday afternoon. VFR conditions under
generally clear skies in the afternoon. Another chance of
IFR/LIFR conditions possible Saturday night.
KSEA...VFR under clear skies early this morning. Low clouds have not
developed as expected and guidance continues to back off on their
development. Elevated NE winds continue at the terminal and are
expected to hinder fog development. Regardless, there is still a
small chance (20%) of IFR/LIFR cigs this morning, between 12Z-18Z.
VFR conditions under clear skies Saturday afternoon, with IFR/LIFR
conditions possible Saturday night. NE winds 8-10 kt this morning,
