This snow event, which should bring 2-3 feet to the High Sierra, will last about 36 hours in the mountains. Here is a look at liquid precipitation levels:
The western side of the Northern Sierra around Lake Tahoe could receive as much as 4 inches of liquid precip. Mt. Rose could get 18-24 inches of nice light powder from this event. Wednesday morning could be quite a treat for those of you who can make it up the mountain.
Dangerous Winds Coming
Be aware, if you live in the foothills of western Reno winds are going to be dangerously high. Some gusts will exceed 125 mph. This type of wind can remove roof tiles and up root trees. Flying debris in this type of wind storm can act like shrapnel. If you live in these areas, stay in Monday afternoon and Tuesday.
National Weather Service Warning
A MAJOR WINTER WEATHER EVENT WILL BEGIN TODAY AS A DEEP LOW PRESSURE SYSTEM CIRCULATING IN THE GULF OF ALASKA PUSHES A STRONG SHORTWAVE TOWARDS THE NORTHWESTERN STATES. GIVEN THE STRUCTURE AND SET UP OF THE SHORTWAVE...EXTREMELY STRONG WINDS WILL OCCUR THIS MORNING THROUGH TUESDAY...PEAKING TWICE WITH THIS SYSTEM. FIRST PEAK WILL OCCUR THIS AFTERNOON AS IDEAL CONDITIONS DEVELOP FOR A DOWNSLOPE WIND PATTERN. THE SECOND PEAK WILL OCCUR AHEAD OF THE COLD FRONT WHICH WILL PASS THROUGH TUESDAY MORNING. RIDGE WINDS ARE ALREADY NEAR 100 MPH IN THE SIERRA WHILE AREAS IN WESTERN NEVADA ARE GUSTING AROUND 35 MPH. THERE REMAINS CONSISTENTLY VERY GOOD AGREEMENT IN THE HIGH RES AND OPERATIONAL MODELS THAT A MOUNTAIN WAVE DRIVEN DOWNSLOPE WIND EVENT WILL AFFECT AREAS IN THE LEE OF THE SIERRA TODAY...FROM SUSANVILLE SOUTH TO COLEVILLE. STABLE CONDITIONS WILL EXIST AS THE AREA WILL BE UNDER THE RIGHT EXIT REGION OF THE JET...WITH FLOW AT ALL LEVELS PERPENDICULAR TO THE MOUNTAINS. THIS WILL SERVE TO ENHANCE THE MOUNTAIN WAVE AND STRONG SURFACE WINDS IN THE LEE SIDE VALLEYS AND POINTS EAST. SURFACE WIND GUSTS OVER 60 MPH ARE NOT OUT OF THE QUESTION. ONE THING TO NOTE WITH THIS EVENT IS THAT IT WILL BE LONG LIVED AS COMPARED TO STRONG WIND EVENTS IN THE PAST. WINDS WILL NOT TAPER OFF UNTIL WELL AFTER THE COLD FRONT HAS PASSED THROUGH TUESDAY AND THE HEAVIER PRECIP MOVES IN.
Looking Ahead, This is a Pattern Changer
The week ahead should remain snowy and wintry. The potential for significant precip stays in my forecast for the next couple of weeks. No April Fools joke here. Get ready for what might be winters last gasp and some great riding and skiing.
