Setups looking more conditional

From Dan: How the crime of copyright infringement took $1 million from me and shut down my operation.

In September of 2025, my work is generating the most income it ever has in my career. Yet, I'm being forced to shut down my successul operation, against my will, due to one cause alone: 95% of that revenue is being stolen by piracy and copyright infringement. I've lost more than $1 million to copyright infringement in the last 15 years, and it's finally brought an end to my professional storm chasing operation. Do not be misled by the lies of infringers, anti-copyright activists and organized piracy cartels. This page is a detailed, evidenced account of my battle I had to undertake to just barely stay in business, and eventually could not overcome. It's a problem faced by all of my colleagues and most other creators in the field.

The ECMWF model has been worrisome in recent days due to its refusal to agree entirely with the GFS about the weekend pattern. It has the jet more west and north, then transitions everything quickly to an eastern trough with ridging/NW flow over the Plains once more. The GFS upper air and moisture forecast looks nice, but there is a massive cap (with 700mb temps topping 12°C - above the threshold for realistic breakability).

The capping may be the deal-breaker on a trip #2 for me. I will just have to wait until the target days start falling within the NAM/WRF horizon - by then the other models should have a better handle on things as well. If I see precip consistently breaking out in that capped environment, I may give it a try.

Based on the current outlook, this probability table charts the chance of the second Plains storm chase expedition starting on a particular date:

2009 Storm Chasing Expedition #2 - Departure Date Probability as of June 2
June 1-733%
June 8-1533%
No trip #234%

It's nice to see that somebody else is looking at this through non-SDS glasses. I've never had success with 700mb temps >12c, so I'm not too excited ATTM. So there are really 2 potential flies in the ointment here. 1) Frontal passage scouring moisture and 2) Thermonuclear capping inversion. WOW, the verification number for this post was a pretty nice storm chase day for us ;-)

The 12Z Euro model is showing a great trough around June 12. And yeah - that verification number is no coincidence :)
