We have an excellent snow pack in the Sierra. Ideally, we would like that to slowly melt away. However, we have a major storm coming in, bringing with it tropical rains that will push snow levels over 10,000 feet for most of the event. If you are one of those people that are scared to death of drought, then you will love this: When we reach April, the rainy season is mostly behind us. Yes, in the past we have seen storms in April, but not like this, not that I can remember. We are talking about 10+ inches of rain for parts of Northern California, 4-6 inches for the Carson Range, 2 inches for the leeward foothills and perhaps an inch in the valley. Snow levels for most of this event will stay above 10,000 feet. Not until the very end will some colder air get forced in and bring snow levels down, but by then most of the rain will have fallen. With all that moisture falling in the mountains melting tons of snow it only has one place to go; DOWN. If you live in a flood prone

A strong storm is headed our way. This storm does appear to be the first and strongest in a series of storms that will change the pattern back to a wet, windy and eventually chilly trend. At it's peak, which will be around Saturday @ noon the storm looks like this: We will start to see a change on late Thursday and then a few waves of moisture come in finally followed by the main brunt of the storm. Snow levels for this event will be very high. I am guessing most Tahoe resorts will see all rain as the snow levels come in above 10,000 feet and remain there for most of the event. When the cold air finally makes its way down, the moisture will have mostly exited the area. This will definitely bring flood risk to our area and some rain, as much as 1/2 inch is coming to the leeward valleys. Check with the NWS if you live in flood prone areas. Temperatures will recover quickly on Sunday and Monday ahead of the next storm. The next storm shows up on Tuesday and will be much

As the last remnants of this major storm wrap around our area and bring in very cold air, especially for this time of year, a major change is on the horizon. We talked about this in our last two posts. Here is the change: As air rotates clockwise around the ridge of high pressure and that ridge of high pressure moves closer to the coast, we can expect a gradual warming and the possibility of mid-70's by late next week in the leeward valleys of the Sierra. We are quickly approaching average snowfall for the Carson Range and Sierra, which is a little deceiving because we had nearly a foot of rain in several very warm storms earlier in the season. That makes the last 3 years of average or above average precip for our region. That was preceded by 4 years of below average precip. Folks, that is how it works. Ma Nature is not on a schedule. This machine that we call our climate is full of peaks and valleys. That is why we always say "average" and not "normal"

The current storm cycle has lasted nearly a month with several strong storms dumping lots of snow throughout the Sierra and Carson Range. That cycle is coming to an end, but not until we get pounded by one more large storm. We have been talking about this storm for about 10 days now and it is not going to disappoint. There will be some shadowing for the Carson Range but we still expect snow measured in feet starting tomorrow and ending early Friday with a 2nd wave on tap for Saturday. Snow levels could approach 8,000 feet when this thing really gets going. Initially however, we are looking at 7,000-7,500 feet. When the heavy moisture comes in the snow levels will rise. How high? Our best guess is above 8,000 feet for a short period of time until a cold front comes in and drops snow levels all the way down to 5,000 feet. For the most part, this will be all snow for Mt. Rose. There is a better than 50/50 chance that snow levels never make it to 8,000 feet. Approaching Storm (Tomor

Act II of our winter storm is knocking on the door and should be affecting most of the Tahoe area by late this afternoon. This storm is coming from the north and is colder than Act I. Where Act I weakened, Act II has strengthened and slowed down. The Carson Range should pick up 2-4 feet of snow tonight and tomorrow above 8,000 feet. This storm is much colder and will be all snow for all areas. Some ares of the western crest of the Sierra will pick up as much as 5 feet of snow. There is a shadow effect to this storm, but we still like our chances of getting a major dump. Expect moderate to heavy snow for the Tahoe area for about 24-30 hours and then some wrap around moisture as the storm moves south and east. The storm should be peaking around 2:00am tomorrow. Here is a look at the forecast for 2:00am tomorrow: OK, back to what we do, which is longer range forecasting. Next week looks good for another large spring storm. That storm is going to come in warm, however. Here is wha

The winter storm that we have been talking about for the last two weeks is now upon us. This is an update on the timing of the storm: The storm will come in essentially two waves. The first wave is just now starting up. It will come in warm with the counter clockwise rotation pulling up moisture from the sub-tropics. This is the bigger of the two waves and will last until late tomorrow night with near constant, heavy snow. The elevation will be high to start, but should quickly drop. I believe Mt. Rose will get all snow, but would not be surprised to see snow elevations at the 8,000 foot level or even a little higher to begin with. The heaviest precip will be from 4:00 this afternoon until late morning tomorrow. Here is a look at the peak of the storm which should be around midnight tonight: There will be a break in the snow that should start very late tomorrow night and last through most of the day on Thursday before the next wave comes in. The 2nd and final wave comes in lat

A rather large and extremely beneficial storm is expected to come in on Tuesday and stick around for 4-5 days bringing wave after wave of moisture to almost the entire state of California and heavy mountain snow to the Sierra. Our current system is trying hard to produce. The first wave went by us to the west and north and the second wave is missing us to the south. However, I think the Carson Range could pick up around 3-6 (at most) inches of snow tonight and early tomorrow morning. Before we get into the forecast, if you did not see this earlier, we were sent a video of Ski Patrol doing avalanche control in the Chutes of Mt. Rose last week. I have been asked to post it again, it is pretty amazing. Mt. Rose Chutes Avalanche Control We have a giant trough of Low Pressure headed our way. Although the models are not in total agreement, we believe here at TWB that this will be a major winter storm for the Sierra and Carson Range. Here are the details: Tuesday at Noon (3/13)
