How to read the rain forecast

Chance of rain (%) is the probability of rain in Montana during that hour, not how long it will rain or how heavy it will be. For example, 60% means that in 10 similar weather situations, it rained about 6 times.

Rainfall (in) tells you how heavy the rain is: under 0.10 in per hour is light rain, 0.10 in–0.30 in per hour is moderate, and over 0.30 in per hour is heavy. In summer, afternoon thunderstorms can bring short, intense downpours and flash flooding.

This page updates about every hour. During severe thunderstorms, flash floods, tornadoes or hurricanes, follow the official National Weather Service warnings for Montana.
