After losing a significant crop to a frost event the forecast missed — how are you making weather-sensitive decisions?

Prairie farmers — has anyone found weather tools that are actually useful for crop decisions, not just general weather?

Context: I had canola in the ground last spring and got hit by a frost event that my forecast tools gave me basically no useful warning about. Not "no warning" — they said there was frost potential, but the uncertainty range was so wide it was useless for making an actual decision about whether to take protective action.

The problem with general weather apps for crop decisions:

- They give air temperature, not ground-level temperature

- The spatial resolution is too coarse for field-level decisions

- They tell you what might happen, not what it means for your specific crop stage

I've been looking at ag-specific forecasting tools but most of the well-known ones are built for the US Midwest and their recommendations are calibrated for those conditions.

What are prairie and Canadian producers actually using for weather-sensitive decisions? Specifically:

- Frost risk at ground level

- Disease pressure windows

- Timing windows for applications

And a meta question: how are you building weather risk into your input decisions when the forecasts have wide uncertainty? Do you make the call based on the probability, or do you wait for more certainty and accept the timing risk?
