If you're planning to watch the fireworks display outdoors in Seattle New Year's Eve, prepare for some light rain and breezy conditions.
"As we head into the day tomorrow, we're really going to see that rain pick up and significant mountain snow, potentially up to a foot in some of our mountain passes," said KING 5 forecaster Lisa Van Cise.
Another stronger storm front will push into Western Washington on Thursday, bringing rain and winds to the region. The heaviest, steadiest rain will fall during the morning and will gradually taper off to showers by evening.
Those heading outdoors to watch the fireworks show should expect spotty showers and breezy conditionsh by midnight, says Van Cise. Temperatures are expected to be around 40 degrees.
A Winter Storm Watch is in effect not only for the Cascades, but also the eastern slopes and many spots around Eastern Washington and Eastern Oregon. Six to 12 inches of snow is possible for the Cascade passes, such as the Stevens and Snoqualmie passes.
"Expect significant snow especially as we head into the day tomorrow," said Van Cise.
Another cold front will move on Friday for a wet and breezy day to start 2010.
High pressure will begin to build in on Saturday for decreasing showers and sunbreaks. And the first Sunday of the new year looks partly sunny and dry.
"Computer models have been inconsistent in the outlook for next week, but the best guess right now is for some rain to move back into the area the first few days of next week. Not too surprising for January!" said KING 5 Meteorologist Rich Marriott.
