Round 5.......

Sierra is reporting 9 inches at the base and 14 on top from yesterday's storm.  That puts the week's total at 4 feet 5 inches.  Yesterday's totals were a little short of forecast.  The heavier snowed stayed towards the North end of the lake. 

A strong low pressure is currently off the coast of CA. The pressures with this storm could be some of the lowest to come over CA. The low will slowly move over Northern CA today. The problem is that the heaviest precip will be coming under the low into Southern CA. Snowfall will be heavier in the Southern Sierra and then lessening as you go North. This benefits Sierra at Tahoe since they are South of the lake.  Expecting heavy snowfall to move in later this afternoon into tonight, with snow showers from wrap around moisture lasting through Friday. Looking for 5-10 inches at the base, with 10-15 inches above 7000 ft. by Friday morning. Another 3-5 inches could fall Friday into Friday night from leftover snow showers. There could be more in areas that see heavier snow bands, and if the storm shifts slightly North the heavier snow would mover further North. That should put Sierra close to 6 feet for the week.

Storm for Monday is looking a little faster now and should arrive Sunday night, followed by another storm Tuesday, and then another around Friday. Monday's storm looks like a 6 incher and Tuesday's is looking stronger. More on those tomorrow after we finish with this week's train. BA
