.DISCUSSION...Rain is moving into the area from the
north and is expected to linger through this evening, diminishing
overnight. As the rain diminishes late tonight, temperatures may
cool enough to support a rain/snow mix, mainly after 3AM but some
evidence shows the switch could start a couple hours earlier. At
this time, snowfall amounts near the spot area will be less than
one inch. Once the precip moves out early Tuesday morning, the
rest of the week is looking dry.

Northerly winds today will remain elevated at around 10 to 20 mph
with high-end gusts near 30 to 40 mph possible. Speeds will
diminish overnight tonight. Lighter northerly winds likely
through Wednesday with speeds around 5 to 15 mph. Winds will be
light and variable Thursday before swinging back to the north at
5 to 15 mph for Friday.

High temps this week will be within a few degrees of 50 with
morning lows near 30.
