Gary Lezak’s Tahoe Long-Range Forecast Tomorrow
First of all, thank you to all who signed up! We have had a few glitches that we are working through. Hopefully, we will get all of those issues resolved quickly. Meteorologist Gary Lezak will be giving the long-range forecast for Lake Tahoe tomorrow. Gary grew up in Southern California and vacationed at Lake Tahoe often. We will dive into the Lake Forecast through March, so don’t miss tomorrows blog. Below is an excerpt of Gary’s Forecast.
GFS Ensemble Model thru Jan 2
Above is the GFS ensemble thru Jan 2nd, which is about when this cycle ends. The GFS does have a good grip on the pattern, meaning the alignment with the Pattern (Lezak’s Recurring Cycle [LRC]), is in agreement. There is a good storm on January 4th that is beyond the range of the above GIF that will end the active part of the pattern and we will enter a small lull until January 9th or 10th when a fast-moving storm will hit the PNW.
It does not appear that we will go through a long stretch without storms–except for southern resorts like Lake Tahoe, Arizona and New Mexico. It looked like there was a 2-week stretch, last cycle, but luckily, the pattern was still evolving, and we avoided a long dry stretch.
For Tahoe, and other southern resorts, its feast or famine. There are a couple of storms left this cycle, before the dry stretch begins. The first being December 21st, then a stronger system on the 27-28. That last storm is not on the GFS presently, it should show up soon.
Tonight’s System Compared to Last Cycle
In the above charts is the system that is coming thru now. You can see the large trough, this cycle, was much farther west last cycle. The teleconnections have caused this shift, that is why Tahoe was missed and we had our first bust.
The high-pressure circulation, off the coast (those two circles that looks like an egg) last cycle, determined the position of the trough. No high-pressure circulation this cycle, so we have more of a linier flow causing the trough to drift east.
This is one of the things that we have to solve, to better forecast the long-range. This happens at least once a year. Last year it occurred in cycle 3, totally devastating the Trifecta storm system.
We are progressing through this small break in the pattern, which you can see in the spreadsheet below. This XLS file is recorded snowfall, along with proprietary data, from the last cycle and was confirmed in the cycles before. The yellow blocks are the specific storms, with dates projected to recur.
Tomorrow, Snow spreads to the southern Cascade resorts Mt Hood Timberline and Meadows. I’m not expecting much precipitation for Mt Bachelor, as it is on the edge of the system. The highest snowfall totals will be around White Pass in the north and Bluewood in eastern Washington, snowfall in the 4-6 range. Expect 2-4 for Crysal, Snoqualmie, Stevens Pass and Mt Hood. Temperatures will be in the low 20’s in Washington to upper 20’s in Oregon.
Tomorrow night, Snow will likely linger Tomorrow Night, with and 1-2 additional accumulation.
Tuesday/Tues Night, likely Powder Day on Wednesday
The next system arrives in the morning on Tuesday. It is coming in slightly slower than the models predicted yesterday. Snowfall amounts will be in the 5-10 range Tuesday with most of the snow falling after the lifts close. Wednesday will be the best day to ride.
Utah and Colorado
This is looking better for Colorado, at the moment, but I won’t count Utah out just yet, Utah has been kicking ass lately. The storm arrives in Utah Tuesday night but won’t reach the strongest until Wednesday afternoon. Thursday should be the best day to ride. Temps will continue to be cold with highs in the teens.
Colorado gets underway Wednesday around noon, for the northern mountains. Wednesday evening for the central and southern mountains. As of now, the southern mountains will be lucky to get 4+, but this is still a long way out so we will keep an eye on the models. Last cycle, it did not reach Telluride, Wolf, or Silverton.
High totals for the northern and central ranges, last time thru, were at Steamboat 7, Beaver Creek 5 and Vail 8. We will dial the totals in by Monday.
