The model is not running

The forecast is fitted on May to September weather, and it is only run over those months. Outside them it is being asked about conditions it has never been shown, so the sensible thing is to say nothing rather than to say something unfounded.

There is also nothing to protect. Late blight needs a living host, and Michigan fields are bare. Forecasts resume with the new crop.

Conducive weather is not a spray recommendation — the model doesn’t know your variety, your last spray, or whether blight has been confirmed nearby. How this forecast works →
