As has been the case this month, the models are greatly over predicting our storms and backing off as the storm nears. This first storm tonight is moving much faster than previously thought and will be all done by noon tomorrow. The storm for Sunday night is now looking like a minor weather event. These storms are also coming in slightly warmer than expected. The next storm in sight is for next Tuesday night and into Wednesday. Again a fairly quick moving storm. After that, it looks like high pressure may move in again. Here is the precip total for the 3 storms: Somewhere between 2-3 inches between now and next Wednesday for the Carson Range. We will take what we can get, but our hopes were much higher for this week. Our friend Paul Huntington hinted to me that we may see a dry second half of January and at least early February. Paul has been very busy but we are hoping to get a post from him for the remainder of the winter soon. Stay Tuned ...

Three storms each stronger than the previous storm are poised to hit Tahoe. We talked about 2 of these storms in last week's post. Not much has changed, we expect the first storm to be the warmest and weakest of the bunch. Unlike last storm, which saw snow elevations at around 10,000 feet, these storms will be much colder. The first storm is the warmest of the bunch and we expect up to 6 inches of snow above 7,500 feet. This is a very fast moving storm, because it will pushed out by a much stronger storm. Here is the forecast for very late on Thursday night: Although this storm lacks a huge moisture tap, there are several waves of precip associated with it. We expect this event to last for about 36 hours and dump 1-2 feet (or more) of snow above 6,500 feet. As the cold front passes through snow levels will fall to around 4,000 feet and I expect the lowest parts of the leeward valleys to pick up a few inches of snow. If you live in the leeward foothills, you could see 5-9 inc

The change we talked about for the last 3 weeks is starting to take hold. The first major storm is knocking on the door. We will keep our forecasts the same. However, this storm is really pulling up very warm, sub-tropical air and snow levels will start out around or even above 8,000 feet. By the time it is all said and done, however, we still believe the Carson Range and Mt. Rose in particular will pick up 18-36 of very wet snow. Warm air will then come in and take over before two very large storms will produce more major weather events, starting around the 15th. We will focus on the long range forecast. This current storm is being covered by the NWS and other outlets, we like to focus on what is coming down the road. Remember, we forecast 10+ inches of liquid for the month of January. Right now that forecast looks pretty good. Here is a look a the forecast for mid-day on January 15th: This is another very similar storm to what we are getting now. I think the possibility does

As mentioned in our last post, our first decent storm of the 2018 begins late Monday, should bring decent precip for most of Tuesday and clear out on Wednesday. High pressure builds in behind the storm, but we feel as though that will be short lived and our next series of storms should come about mid month. These past two storms were exactly as advertised. The next storm will come in warm and eventually snow levels will drop. Again, the big winner on these sub-tropical storms is Mt. Rose with it's high base. Here is a look at the forecast for very early Tuesday morning when the largest wave of precipitation hits the area: At the risk of sounding like a broken record, our forecast has pretty much remained the same for the last five days. Here is the precip outlook. This storm could come in as high as 8,500 feet but will quickly fall below 8,000 feet. We look for Mt. Rose to pick up between 18-36 inches by Wednesday morning: Not bad for this year, but nothing like what

We have been locked under this coastal ridge of high pressure for weeks now, but as with all things related to weather that is about to change. The change begins slowly on Wednesday night with a weak system coming from the south. Although this system has plenty of moisture to work with, it is too weak to expect anything of significance. We are much more impressed with what starts around Friday at noon and could last up to 30 hours: Here is the forecast for early Friday Morning: Again, this is another weaker system, but does have some potential for precip. Both these system are going to be very warm with snow levels starting around 8,000 feet or possibly slightly lower. Mt. Rose will probably be the big winner again. We are tracking a storm for just over a week from now that looks very positive. It has cold air, energy and moisture with which to work. Usually that combination can usher in much needed heavy snow for the Sierra. Here is a look at the forecast model for a week

The cold front we talked about last post is right on time and we are sticking with 8-16 inches of champagne powder for Rose. The deeper the less likely for skiers and riders to break through and scrape the crust underneath. I am fairly confident we are looking at a good 10 inches and if things go just right up to 16 inches. Then the ridge digs deeper. The coastal ridge in the jet is causing storms to go well north of us. This storm for tomorrow is due to that ridge flattening out. Here is a look at tomorrow: One sneaky little trough in the jet is going to allow this moisture starved slider to drop in straight out of the north. However, there is a substantial cold front associated with this storm and snow ratios could hit 15-20 to 1 depending on the timing of the moisture and cold air. The above graphic shows the ridge of high pressure in jet stream. This is causing all weather to move north around the ridge and will keep us high and dry for some time, unfortunately. Here is a

With our ridge of high pressure getting pushed slightly west, that opened a very narrow door for what we call a slider storm. That is a storm that comes from the north and east and slides down the leeward side of the Sierra. Usually, these storms have very little moisture but they always bring cold air. In this case, we finally got some winds in the valley to change the air and clean it up. That was the first sign that we are starting to see a pattern change. The next sign will come this Wednesday in the form of an actual storm. Not a big storm or even a moist storm, but a storm nonetheless. Although this storm will come from the north and west, it will be more north than west and will bring in even cooler air. Here is a look at the forecast for Wednesday @ noon: What we like to see is for these storms to tap into an active moisture plume from the south and west. As you can see this storm does not have much moisture to work with. Here are the forecast precip totals: This wi
