The National Weather Service in Seattle has changed the Winter Storm Watch tonight to a Winter Weather Advisory in effect until 6am Tuesday morning. A winter weather advisory for snow means that snow and ice on some roadways could cause travel difficulties. Snow showers, if any, could bring a dusting to 1 inch of snow overnight into Tuesday morning. If (and this is a very big if) a convergence band develops an additional 1-3 inches is possible.
For those hoping for the snow, you may be out of luck. Computer models have been very inconsistent with this developing weather pattern. Radar right now doesn't show anything promising so I suspect we won't see anything overnight outside of a dusting. It could still change, but I think our chances of a snow event between now and Wednesday at this time are very small.
Temperatures, however, are still going to drop down into the 20's. Tuesday and Wednesday will have daytime highs struggling to make it past 35°F. Thursday our next storm system comes in, and at this time is still expected to initially start as snow. Accumulations still do not appear to be likely according to most computer models. I'm paying close attention to this developing system as well and I'll post updates as we get closer to Thursday.
