The Weather and You

It is Spring and we have had some spring weather last week when we hit 70 in Oakland and 75 in the Tri-Valley.  This nice warm-up is almost a memory now as the pendulum has swung back to winter.  The Sierra has seen over a foot of new snow.  Norden at historic Donner Summit on old US 40, the Lincoln Highway now has 88” off snow on the ground and seasonal total snowfall to date of 307”.  The last three days of this week could see another 48” of new snow pushing the total above the average annual.l snowfall of 350”.  This is excellent news because this will give us the first back to back winters of above snowfall in quite awhile.  The water supply at EBMUD shows total system storage of all the Lakes and reservoirs is at 84%, which is 105% of the historic average.  This years Spring run-off should fill all off the High Sierra lakes and reservoirs. Looking at Longer Range Forecast Models, rain is likely for the last weekend of March which will spill into the first of April.  El Nino is waining and it appears that we are going into La Niña by the start of summer.  Looking at statistics which look at summer temperatures for La Niña following an El Niño Winter show near to below normal temperatures for the entire East Bay and Tri Valley area which boils down to average to below averages temperatures for he is summer.  Considering the rate hikes from PG&E, that’s probably good news!
