Weather Summary

After a few weeks of high pressure and air stagnation, a typical winter storm
is expected to cross the Pacific Northwest. Although rain and wind amounts are
typical with this sort of December system, snow levels will be dropping quickly
after the front passes, and this could lead to snow over nearly all area
passes, including those on Interstate 5 between Grants Pass and Roseburg. The
valley floors are not expected to receive any accumulating snow. That being
said, if a heavy snow shower does occur Tuesday night, a few snowflakes on the
valley floors are not out of the question. Overall, it looks as if snow levels
will stay around 2000 feet or above. Post-event conditions are not conducive to
melting as we should remain cloudy on Wednesday and then clear out Wednesday
night allowing temperatures to become cold across the area. This means that any
accumulated snow could be somewhat longer-lived than normal.
