It now seems model solutions are coming more into agreement, at least for the beginning of the forecast period. As usual, this makes the departure date more complicated. A few factors are coming into play.
It now seems model solutions are coming more into agreement, at least for the beginning of the forecast period. As usual, this makes the departure date more complicated. A few factors are coming into play.
- Models are in fair agreement that a pretty good setup is likely on June 24 and 25 in eastern CO and vicinity
- Models are in okay agreement that better setups will occur starting on June 26
- Models are showing some serious instability toward the end of the trip if we had a late departure
- Models get worse and worse the farther into the future you go
So do we go and get good storms and maybe really good storms, all while having to return when there's the conditional chance of some *great* storms, or do we leave a couple of days later, catch what will likely be really good storms and then unknown after (but models are saying it'll be really good)?
