Rain makes long, lost appearance in Seattle

Rain makes long, lost appearance in Seattle

SEATTLE -- It's something many Seattleites are used to seeing for several days a year, but you could pardon them if some were dancing a jig to see it once again: rain.

After more than a week of dealing with snow and icy roads, many residents got to see some good old-fashioned Northwest rain Wednesday afternoon as an incoming storm brought in some milder air and started to melt the unusually deep snow pack draped around the region.

But the snow isn't going away without a fight. In fact, many areas were still reporting snow showers as late as Wednesday afternoon as the cold air was particularly entrenched in some spots, and new snow accumulations reached 2-4". For others, what fell Wednesday morning was being washed away Wednesday afternoon.

But we still can't shake the cold, as cooler air will move back in on Wednesday evening, likely dropping the snow level back to near sea level again. In the storm's wake, we'll see scattered hit-and-miss showers that could be quite intense as the atmosphere becomes unstable Wednesday night through Christmas Day. A WINTER WEATHER ADVISORY remains in effect through Thursday afternoon for all interior lowlands.

New accumulations with these storms will be quite variable depending on whether a shower finds its way to your home and how long it sticks around. You could get anything from rain to a mix to snow, and if it is snow, you could get a slushy dusting to as much as 4".

Also, of special note -- some forecasting models suggest a steady band of snow could set up shop somewhere in the region -- with one even suggesting over the central Puget Sound area. This is still highly uncertain, but could put down some solid snow accumulations again -- perhaps 4" or more. Again, let me stress, this is highly uncertain, but something that needs to be watched. Keep an eye to the radar Christmas morning if you have travel plans for the afternoon.

Snow showers taper off Christmas Night, and we'll begin clearing the skies. That will allow overnight lows to drop into the 20s again, making for potentially slick roads -- and this time the ice might be more difficult to traverse if the road is bare and free of any compact snow for traction.

Friday will see a warmer storm and is finally the knight that slays the snow dragon. It might briefly begin as snow, but should change to rain fairly quickly and stay that way. The rest of the weekend will feature rainy and breezy conditions, with highs in the 40s.

Pay attention to your roof

This upcoming repeating pattern of snow, then rain, then freezing overnight temperatures, will put extra weight on the large snow packs from earlier storms. Those with flat roofs needs to take precautions to get the snow off the roof. Car ports are vulnerable as well.

Also, as this snow begins to melt in earnest Friday through the weekend, ponding and urban flooding problems could arise. Be sure to try and keep storm drains clear of ice, snow and debris.
