It’s just weather, it’s been here before

It’s just weather, it’s all been done before and will repeat again. Not Global Warming, not Climate Change, just normal weather. Here’s a glimpse of two Februaries, 2015 and 1934.

Are The Good Times Over?

Wow, 22 degrees this morning 74 this afternoon. Looks like this pattern will stick around for awhile with no precip in sight. We’ve been in a historical wet period for the last 500 years and it looks like the good times may be over. We are so screwed.

Drought Stricken California Suddenly Green

Some encouraging news compared to last year. From Roy W. Spencer, Ph. D.

Heavy rains over the last few weeks have led to a sudden greening of much of California, as revealed in yesterday’s color satellite image compared to exactly 1 year ago (click for full size):

Many stations in Northern California have recorded over 20 inches of rain, and Folsom Dam has received a whopping 62 inches of rain this month. Lake Shasta, the largest reservoir in California, has erased almost half of its deficit below its normal level for this time of year.

This is some great news for our area from Dr. Roy Spencer.

The latest in a series of Pacific storms hit California yesterday with high winds and over 6 inches of rain at Shasta Dam. A number of mountain stations that feed the reservoirs in N. California, which are at very low levels from the continuing drought, have registered over 10 inches of rain in the last week.

With yesterday’s heavy rains, Lake Shasta rose a spectacular 10.6 feet in one day, which added over 130,000 acre feet of water volume to California’s largest reservoir. That’s enough water to fill 65,000 Olympic size swimming pools.

The following graph shows that there is still a long way to go to reach even normal water levels on Lake Shasta:

Nevertheless, it also shows how the reservoir can recover in only one year, as it did from the 1976-77 dry period to the 1977-78 wet period, the result of rains from weak El Nino conditions.

The current El Nino conditions in the Pacific are contributing to the current wet and stormy period, which will need to continue before we can even begin to talk about the drought being over.
