SEATTLE -- Our three week pattern of being colder than normal is not going down without a fight.

Snow fell across most of Western Washington Sunday evening as some lingering cold air put up one last stand before warm air coming in overnight Sunday will put the kibosh on any upcoming lowland snow chances.

Most areas in the Puget Sound region were reporting about 1-3" by 9 p.m., but the Kitsap Peninsula was hit harder, with reports as high as 3-6" across Bremerton, Poulsbo and Port Orchard. Roads were said to be treacherous along SR 303 and SR 3.

Despite the heavy snow and dicey travel conditions Sunday evening, there was hope that conditions will improve in time for Monday morning's commute. The incoming storm has much warmer air, and a mild, south wind should increase during the early night hours, changing the snow to rain by midnight. Many coastal locations, which had received 2" or so of snow earlier Sunday, were already into the low 40s by 9 p.m. with a moderate to heavy rain.

In any event, we are not expecting freezing temperatures overnight -- temperatures should actually rise into the upper 30s/low 40s by dawn, so the greatest challenge would be slush in places that received more snow than could melt off before dawn.

Once we get into Monday, we'll see rain taper to showers for the afternoon. Then, by Tuesday, we swing to the other side of the pendulum as much a much warmer storm moves in. That will bring rain through Thursday morning, with snow levels over 5,000 feet and lowland temperatures approaching 50.
