SEATTLE – Maybe you've spent the last day or so at clear the second winter storm this month

Mother Nature is about to ruin your job with inches of snow more than expected

A third winter storm is about to be announced will blow in the Puget Sound area Sunday night with a probability of 1 to 3 inches, with a fourth stronger storm imminent for Monday later at night with several more inches of snow likely.But this is the last storm that could again have serious repercussions on the region, but this time, we have new wrinkles.

The first storm of Sunday …

The storm that Announcement Sunday afternoon would be normal The Seattle Freak Out Level 8 was born, but today it will be child's play compared to the first two we've already gone through. A low pressure area develops Sunday morning near Vancouver Island and will drift off the coast, then move rapidly inland through the Puget Sound area and I-5 corridor at the end of the day. afternoon and in the evening. less snow.

It is expected that snow will form within 15 to 15 hours. and continue to snow until about 9 pm, then gradually decrease. Most forecast maps give general accumulations of 1 to 2 inches with some isolated spots that can see 3 to 4 inches. For many, it can be difficult to notice with 6 to 10 "already on the ground, but these surfaces perfectly cleaned? Buried again.

The night of Sunday night will remain a little cloudy, so less difficult than the last nights,

And then, the most important winter storm occurred Monday …

Monday morning is a very short break – the ride will be no snow, only persistent problems related to the Previous snow and ice Monday night ride does not seem like snow

A much more powerful storm – perhaps the strongest of the group to date – is already developed in the Gulf of Alaska, but has its eyes on western Washington, but since it will have spent quite some time over the Pacific Ocean, this storm 1) has more moisture and 2) has warmed The trajectory of the storm will be decisive for its unfolding nt, with several scenarios at stake and perhaps very different impacts in the region.

Generally speaking, it is still cold enough that, as soon as the storm arrives, the snow starts everywhere, developing from west / southwest to east / northeast on Monday afternoon. Expect heavy snowfall Monday afternoon or evening. Just like Friday, Monday night travel is under threat. Friday we were lucky because it was warm enough so that the snow did not stay on the blocked motorways before the congestion was relaxed. This may not be the case on Monday, especially if snowfall is more abundant.

Here is the key: unlike the last two storms that have continued offshore and south, we now under the cold and the north wind On the side of the systems and everyone with snow, this storm arrives as a more traditional rain storm track from the western Pacific. On the north side of the storm is the snow side as it keeps the north winds cold. Being on the south side is the hottest side while the southwest winds are milder.

Thus, depending on the exact location of the storm, some areas – perhaps many areas – may turn into freezing rain their way to maybe then just a straight rain later. A heavy freezing rain pouring over several inches of snow? Eww.

The forecast models still disagree on the exact trajectory of the storm; some keeping it further south, which means heavier snow accumulations in the area with little or no change in rain; others move it further north, which places a greater part of the region in the possibility of rain in the freezing rain.

The further north you are, the more likely it is that the snow is complete from beginning to end. Conversely, the further south you are, the more likely it is to transition to freezing rain and possibly rain. Where does this transition occur? That's the million dollar question.

At this moment, this line is … Downtown Seattle and Bellevue. If you live north of the city, you may see heavier snow totals; living in the south of the city puts you at greater risk for the transition of the winter mix. Again, the further north you go, the more snow is abundant; further south, the weather is warmer and faster, with freezing rain.

Of course, freezing rain causes a lot of headaches, making power outages more likely because of extra weight on trees, roads and sidewalks. So, at least, be ready to deal with additional power cuts and extremely treacherous conditions.

Oh, and do not really think about trying to cross the mountains either, where it's possible that 1 to 2 feet of snow is possible. The Winter Storm watches are also in effect there …

The snow / mix / rain will diminish during the day of Tuesday with a tendency to dry out from Tuesday to Wednesday. This storm may have a positive aspect in that blending with the warmer air will push us out of the freeze cycle to create a "cold weather" pattern. Other weather systems are still expected towards the end of the week, but the snow levels can sometimes exceed sea level, which gives us more difficult predictions, in which the altitude and the sea level are higher. Time of day has their say as to who will have the snow and who will get the rain as opposed to everyone getting snow. Easier on the trips; more difficult on the accuracy of the forecasters!

While we could begin to see the 40-degree mark towards the end of the week, there are still 45 elusive in the foreseeable future.
