It's been around more or less since the flip in 2013 with a brief break in 2014-2016 but returned strong again (though this year we seem to have a cooler influence) but the ridge is still there. Each time they forecast rain in the near range out goes the chems and the rain 'magically' vanishes. We get 10 percent of whatever was the forecast a week out.
If the forecast was 2-3 inches on the GFS weather model expect that trickled WAY down to almost nothing. It's almost laughingly predicatable yet weather nerds seem to fall head over heels over a OMG fantasy run. I don't bother posting anymore over there as they all act like smoker dopers.
Ridiculously resilient ridge according to google
As a result, January 2022 will go down in the record books as the driest January on record (since at least 1895) for most of the San Joaquin Valley, the Central and Southern Sierra, and pockets of the Sacramento Valley and western Nevada
There's also interesting research regarding California. Somehow some of the fires jump from street to street and the green of the trees remain intact. It's a very interesting phenomena and of course the official explanation is just bogus.
I don't buy the official explanation one bit. Something related to DEWS is going on.
