.DISCUSSION...High pressure will gradually slide overhead through
the day Saturday. As such, precipitation chances will remain
quite minimal, winds fairly light, and conditions dry. Despite
that, strong mixing and modest transport winds will support
excellent ventilation and associated clearing index values. A weak
embedded system will pass through Sunday as the high shifts east,
which will result in an increase in wind magnitudes as well as
isolated to scattered afternoon showers and thunderstorms. Given
the precip chances and slight uptick in moisture, humidity values
will trend upward slightly. Ventilation/clearing index values
remain excellent.
