Dew points down to -35 in San Diego county per NWS

 

Wow, that's crazy low!

 

Was just watching live the fire jumping the 101 in Ventura.

More fires reported in San Diego county today though wind speed is generally lower than it has been. All the smoke is blowing out to sea and actually being reported as far north as Monterey Bay. Once the wind turns onshore we will have serious health problems.

 

78/ 61

No doubt about it; this is a shitty winter :angry:

Winter does not start until another 2 weeks. And as usual, coastal areas will probably not get their peak of cool weather until next May, when the "rainy" season will be long over.

 

Blocking patterns that last for weeks or months are a feature of climate change.

I am really bummed but others have pointed out that a dry December does not, by any means, guarantee a dry winter!

NSW_LA has an animated graphic projection of the smoke from Ventura/ LA fires turning onshore this afternoon moving into the Basin/ Orange county. We've escaped the smoke so far due to offshore winds but a northern wind will turn the smoke toward metro Los Angeles. What a miserable situation.

Add insult to injury: snow/ sleet being reported in Brownsville [lat: 25.90N] and New Orleans [Lat: 29.95N]

Weather is all out of whack. As climate change continues we will get December temperatures in the 60s as far north as Anchorage and snow at sea level in tropical regions. This will not be the case every day, but there will be times it happens.

 

Record strength troughs will bring cold weather closer to the equator than ever at times while record strength ridges will bring 100 degree offshore flow events in December and January to Southern California.

Data agrees with you, sadly

Actually getting a little sea breeze right now, which is quite a change from the last couple of days, but the moisture has been pushed so far offshore lately that it does not help the humidity very much. Would not be surprised if the ocean level dropped recently with all the Santa Ana Winds.

 

So far there is not too much smoke in the air, but some cirrus clouds are filtering out the sun.

Windy through the night. At least we haven't had to use the furnace in the morning though other calm areas are experiencing minimums in the 40's or cooler.

Temperatures go from 47 to 74 in just three hours at KFUL. Looks like another day in the 80s with the maximum sun angle not even reaching 35 degrees.

 

Meanwhile in Miami, temperature was 80 near sunrise with dewpoints in the mid 70s, but the cold front that brought all the snow to the deep south is moving through there and bringing rain with the temperature down to 65.

I don't know how to exactly describe it but there is a feel to subsidence.  Sometimes a warm day will stay warm as the air descends; it is almost like you can feel the atmospheric pressure.

Wouldn’t it be possible for record cold troughs to reach into California as well in this whacky scenario of yours?

Yes, that is why last two Junes there was snow in the Sierras followed by Palm Springs temperatures of 122 F a few days later.

 

Eventually some time Southern California will get some sea level snow followed by 100 degree temps in December one week later. That's what climate change is all about. Even though the world is warming, the stronger troughs will bring polar air further south than ever before while some place else is having severe winter heat and droughts. The jet stream is getting more wavy.

What are you basing all of this on? There have been plenty of blocky fall/early winters like this in the past.

 

There is plenty of data that supports climate change but there isn't any data that supports your thoughts above (that I know of) or that the jet stream is "getting more wavy". 

Cold Season 2023/24:

Total snowfall: 26"

Highest daily snowfall: 5"

Deepest snow depth: 12"

Coldest daily high: -20ºF

Coldest daily low: -42ºF

Number of subzero days: 5

Despite previous model runs showing smoke moving southwest into the basin/ San Gabriel valley/ Orange county the wind continues to direct the smoke WNW toward Santa Barbara. Nevertheless many are suffering hay fever/ allergies from the dry dusty winds; I'm living on antihistamine. I'll just stay inside and switch between NFL games featuring the Chargers vs Redskins and Rams vs Eagles playing at the same time. :)

A few winters ago California had record heat for much of February while parts of the Northeast had record cold and snowfall caused by the polar vortex. We were stuck in the same pattern alomost all winter. Some meteorologists expect droughts, snowstorms, hurricanes, and floods to be more intense than ever before. In 2010 Moscow had the hottest summer on record, not even coming anywhere close to the previous record. They had crazy fires like California had this year. All of this points to stronger and more persistent troughing and ridging. The stronger a trough or ridge is, the higher the amplitude of the waves in the jet stream.

All that talk about troughs is making me salivate. Growing up I remember periods of hot weather in December. Aver max: 75° in 1986 & 1994. The past 10 yrs have featured many cool Decembers including last year: 66.8° / norm: 68°
