What went wrong with the upcoming wet pattern/budding niño base state? Will there ever be a prolonged rain pattern again?

Okay seriously, we got burned by another head fake. The forecast for the Memorial Day soaker didn’t disappoint for the first time in ages, and in the week leading up to it the models did show it ushering in a wet pattern. Yet when the system ran its course the follow up rain events were can kicked an additional week and are now in the process of collapsing.

Since 2023 we’ve get these big rain events that happen roughly 6 months apart which mathematically should usher in a wet pattern but every time said pattern fails to materialize despite the storm verifying.

Did something else break in the atmosphere to make things permanently drier? It’s not supposed to be this hard to get a wet pattern here.

Good question. Notice the amount of clouds in the sky on an average day. The last few days it was better, but we were really clear in May. A few years ago in February 24/28 were completely clear skies. We are veering towards less precip patterns in the last few years.

Hopefully something pops up. Some afternoon strong thunderstorms would be nice. It's been a real snoozer since Sleet fest.

Persistent NW flow with breaks of southeast ridging are not a good recipe for rain in these parts. The NW flow is the biggest culprit. It's why we've had these incredible spells of nice weather this time of year, but it's a detriment to rain chances due to increased dry air aloft and relevant down sloping potential when winds shift westerly. Need more persistent southwest flow with moisture advection. Haven't gotten into that yet.

Therein lies the rub, there's been ample opportunities for that to break down these last 3 years but when that opportunity arises the nw flow abruptly injects steroids or if it is beaten back it's only fleeting and it comes roaring back in as little as a few days. A niño should be able to overcome that but like in 2023 we're instead dealing with winter style futility until we're well past the summer solstice.
