The First of Two Strong Storms Continues

Summary

Impressive totals this morning out of the Cascades, with additional showers that may be heavy at times. Tuesday will feature mrke of the same and the second storm in this series will arrive on Tuesday night. With heavy snow through Thursday morning, significant additional snow totals are expected, before another showery period starts. There are still no signs of extended ridging in the long range.

Short Term Forecast

The resorts in the Cascades saw rain transition to snow on Sunday during the warm phase of the storm, and heavy snow during and after the passing of the cold front. Showers continue on Tuesday and then snow becomes heavy once again on Tuesday night as the second storm arrives. A warm front will cause snow levels to rise through Wednesday afternoon, but it should remain all snow at the resorts. After another strong cold front sweeps through the state on Wednesday night, heavy snow will transition to a more showery regime on Thursday morning. 

The heaviest snow of the first storm is mostly over with, though some more intense snow showers are possible on Monday, especially in the convergence zones. An additional 2 - 5 in are expected across the Cascades through 4 pm, again, with locally higher amounts if and when a convergence zone develops. 

Snow showers become more scattered Monday evening, with another 1 - 3 in by Tuesday morning. Stevens and Snoqualmie Passes could do a little better than that depending on the convergence zone as well. 

Showers will continue on Tuesday ahead of the next storm that will bring more heavy snow on Tuesday night. Another powder day is on tap for Wednesday, with 4 - 8 in overnight (4p - 4a). Snow levels continue to climb on Wednesday as heavy snow continues during the day. 

While Wednesday morning will feature significant additional accumulations, snow will be getting denser, resulting in an upside-down layer that will increase the avalanche danger. Snow levels should remain below base elevations, from about 2k in the north, 3k in the central, and 4K in the south. Snow levels will remain like this through Wednesday night. A strong cold front will once again barrel through the state on Wednesday night, turning winds to the west-northwest, and sending snow levels down below 1k feet. Heavy snow will accompany the cold front and 6 - 12 in can be expected by morning.

Snow showers, heavy at times, will continue during the day on Thursday as well, adding another 3 - 6 in on the Cascades. This will continue Thursday night and into Friday. Several more inches are possible during this time. 

That's a lot of snow. This should result in 2 - 4 feet of additional snow through Friday. The winds will be very strong during the second storm, especially on Wednesday and Wednesday night. Impacts to lift operations are possible and the snow quality will take a hit. The winds need to be monitored closely, and I will continue to provide updates on that.

Extended Forecast

We're still looking at an active pattern in the western US with another storm approaching early next week. It's still too early for details but some of the models are showing a favorable storm track for Washington. 

Thanks for reading the Washington Daily Snow!
