.DISCUSSION...

High pressure continues to dominate the weather pattern today,
resulting in clear skies with light winds. Temperatures today
only expected to reach the low 40s.

Cool tonight with low temperatures just below freezing. Winds
and cloud cover increase overnight. An area of low pressure
to our northwest will lift a warm front north through the
region early Sunday morning. This may bring a brief mix of
rain and snow early, perhaps even a few sleet pellets.
This will quickly change over to rain by 9 or 10 AM. Rain should
be generally light and only last for a few hours before tapering
off during the afternoon. Winds pick up late in the afternoon to
around 20 to 25 mph.
