Tahoe Daily Snow

A Waning Winter...
Update
I did a long and detailed post on this week yesterday. This morning I will just go through some small changes.
We are heading into a colder week with several chances for some snow. Today will still be mild with highs in the 40's on the mountains and 50's at lake level. We could see gusts in the mountain tops to 40+ mph.
Then the colder and more active weather moves in for Tuesday through the weekend. The first storm moves in late tonight into Tuesday. The storm continues to show a bit of a split. We have reduced the total precip slightly each day the last several days. I think 5 days ago the high end forecast through Wednesday was 17 inches along the crest, and this morning it is a foot.
The heaviest precip is expected during the day Tuesday. With the splitting nature the colder air is also delayed a bit in moving in. Snow levels may sit between 7000-8000 feet most of the day Tuesday before falling Tuesday night below lake level after most of the moisture moves out. Then the trough passage on Wednesday could bring light snow showers could bring a coating to an inch of snow.
Here is a look at the latest model run of the GFS for total precip for the Tuesday-Wednesday system.
You can see the heavier precip to the North and South. The European model shows a good split as well with a lot of shadowing for the East side of the lake. Temperatures the rest of the week and into the weekend will only be in the 30's on the mountains, and near 40 at lake level. Winds could gust to 50 mph up high Tuesday and diminish Wednesday.
Here is a look at the updated total snowfall forecast through Wednesday. Most of this falls Tuesday, with an inch of it tonight, an inch Tuesday night, and an inch Wednesday for the high end.
We have a break Thursday with some sun and cool temps continuing. Then the next storm moves in for Friday-Saturday. This storm is also trending towards a split with a downward trend in the total precip amounts in the latest model runs. The GFS has slowed the heaviest precip until Saturday, the European is still bringing it in Friday. We will have to keep watching the splitting trend.
The snow levels may sit between 6000-7000 feet for this storm. Here is the updated snowfall forecast based on the latest model runs. Similar to the Tuesday storm.
We may see a break Sunday and then one last cold and weak cold system may move through Sunday night with a dusting of snow.
Here is the total precip forecast for the next 7 days.
Next week we may see the ridge build off the coast keeping most of the storms and moisture to our North. We will watch to see if we can get more storms in April. It does appear big storms are done for now, if not for the season. We may be more likely to see smaller storms with snow in inches instead of feet now.
Stay tuned...BA
