MLB opening day is here! But how will weather play a role in the seasons 2026 start on the ROWI scale? FOX Weather Meteorologists Craig Herrera and Britta Merwin break down the impacts for some of the upcoming games.
CHICAGO — Major League Baseball’s Opening Day is set to get underway Thursday and FOX Weather has your complete hardball forecast.
WHAT IS FOX WEATHER’S ROWI?
FOX Weather has you covered throughout the long road to October with FOX Weather’s Exclusive ROWI — the Risk of Weather Impact. It’s a scale based on a comprehensive set of factors, customized for each sport that take into account precipitation, wind, temperature, humidity, lightning risk, and other weather conditions that could impact a particular game.

The ROWI can determine the likelihood of delays and cancellations, but also highlights the weather conditions that measurably influence the game’s result.
In terms of baseball, a HIGH ROWI means a game is likely to be delayed or postponed due to weather.
A MEDIUM ROWI means that a game has a chance of being delayed or postponed due to weather and/or the ambient weather conditions are enough to measurably influence the game’s outcome.
A LOW ROW means that weather is not expected to have a significant impact on the contest and a ZERO ROWI means that games resemble indoor conditions.

Yankee slugger Aaron Judge will aim to neutralize any wind blowing into Oracle Park, after leading baseball in average exit velocity last year.
