As winter drags on, some people wonder whether to pack shorts for a late-March escape to Florida, while others eye April temperature trends in anticipation of sowing crops.

Mackey is bringing his expertise in artificial intelligence to the table in a bid to increase the odds of accurate and reliable forecasts.
“The subseasonal regime is where forecasts could use the most help,” he said.
