If you only had three single parameters to forecast a chase with, what would they be? | Vlog

This video is part of our vlog series (and our 2018 relaunch).

In this video Sanner plays a fun thought experiment and forces you to pick the three parameters you’d forecast with if you could only have three. However the rules are a bit trickier than they sound:

1)No obs whatsoever (aka no radar, satellite, surface obs).
2)No composite or multi-parameter indexes (aka no SCP or SigTor).

Basically you can only pick single parameters with which to forecast with.

Sanner’s picks:

1)Surface dewpoints
2)500mb winds
3)850mb winds

What three would you pick?
