Rain in Northern California

Holy mackerel! This is the driest fall/winter I’ve seen for a very long time. I’m afraid we are in big trouble with our lack of rain. The animals, forrest and Human survival depends on rain. Can’t they ‘chem-trail’ clouds that will produce rain here?! They’re doing the trails anyway. Why not HELP us all out?! Any answer on this would be appreciated. It’s doable- it’s been proven!

Hey y'all! El nino or el Nina really going to hit San Diego?

Ok I'm a weather junkie! I love crazy weather I hate how sunny it is in San Diego! My question is......... do we have a el nino really coming up? Like I need rain! Is San Diego going to get before or after thanksgiving? I seen on Facebook San Diego isn't looking good for a el nino or el Nina. I have my fingers crossed we have a strong el nino making it's way! Please let me know if anyone has a time frame or know if it's even going to happen. Thanks:)

Niña is a feminine word, “La niña” not el.

No rain in the valley

No rain in October and we're now in November I live in Modesto California and it hasn't rained I'm kind of worried. My question is, is the government messing with our weather? Or are we going through major climate change? It seems to me like the whole world is changing and not for the good

Any rain between Nov 28th and

Any rain between Nov 28th and Dec 4th for Los Angeles/Hollywood area ?

Dry November

hi all i,m a retired US Navy meteorologist here in San francisco, I grew up in the lower Sacramento valley near Galt. the weather the last few years has been anyhting but normal, which leads me to the new belief that this is the new normal. my studies show that for the exception of 2017 when the storm door was wide open from Oct (16) all the way to May, the State has been dry especially the first few month of the rainy season Nov, Dec, and Jan. which climate wise is our wettest period . Now its 2018-19 rainy season and here we go again. looking forward at the forecast models its dry for the rest of the month. maybe a weak system around the 18th , but its looking less likely as we mover along through the Month. i love the rain its the Atmosphere in motion, hopefully i am going to be wrong in my forecast for the new normal.

Dry November and December

I agree with Mike that it will be a dry winter. In particular, it would be nice to have a white winter in Yosemite Valley; alak and forsoothe, I predict no rain or snow for Yosemite Valley, just the same old warm, sunny days. It hasn’t been cold in the valley at all for the month of October. October also ‘boasted’ one or two days of rain and the autumn leaves did not show with the brilliant colors like they did in October 2016. Hope I’m wrong.

Rain

I have to agree. This weather feels very unnatural to me. I miss the rain. Think of how things look, smell, and feel the morning after a rain storm. The dry air is starting to work on my nerves. Las Vegas has seen more rain than us.

RAIN

Okay. I am a big wet weather fan. I heard this on a weather forum several years back. Pls don’t laugh
After that huge earthquake in Japan. I heard it was so powerful it actually tilted the earths Axis 1-3 percent. If so would that have shifted the weather? So San Francisco would actually be LA type weather? Please don’t laugh

San Diego? D

Why do they even bother selling boots coats and umbrellas here??! I hate this. Has anyone heard that we could get ANY interesting weather aside from our day in day out sunshine down here? We used to in the 90’s!
