Forward toad crossings predicted to be (mostly) complete on 2024-04-17(There will still be a few toads returning to the woods from the reservoir on rainy nights.)


The below table shows past days and the number of toads seen. Note, on Feb 28th, the original forecast was 290 toads. Then as the forecast got colder, it changed to 90, then right at dark the forecast went all the way down to 0. I consider this a "win" for the predictor because it did correctly predict the first toad night, sort-of.
