Fully operational, with a few hundred users on it presently. Send us an email.

Hi Matt
We used Skysight for planning some great 500K flight here in Michigan and it was right on. Thanks. Question: What the hell was going on with the weather, Pilots all over the upper mid west and east had never seen this before. Cloud bases over 10k that a painter couldn't paint as beautifully. 500K and 750K flight all over the place. So I'm curious as to what caused this to happen. I know the main reason is that there was 0 contest going on. But what was causing this to happen, was it because we were so dry or was it because of the big dew point spread? Or just a combo of it all . I'd like to hear what experts have to say about this and what do we need to make it happen again?
Thanks

Looks like a nice pool of cool, dry, unstable air - beyond that I think you'll have to consult your local meteorologist to answer the "why", I'm just not familiar with what drives your regional weather patterns, but I imagine there are some medium-term climatic factors that drive whether you have a 'good' season or not.

In Australia for example, our season is driven by the ENSO (https://en.wikipedia.org/wiki/El_Ni%...n_Oscillation), SAM (https://en.wikipedia.org/wiki/Antarctic_oscillation) and to a lesser extent the SIOD (https://en.wikipedia.org/wiki/Subtro..._Ocean_Dipole). When we see a strong La Nina forecast for summer, we know it'll be a below-average season in my region.

Similarly, large-scale driving weather models may perform better or worse in some climate events, so we sometimes the "the forecast was better last year / much more accurate this year" phenomena when nothing may have changed.
