Sometimes weather can play an important role in an adventure.
Table: Random Weather is an appropriate weather table for general use, and can be used as a basis for a local weather tables. Terms on that table are defined as follows.
Calm: Wind speeds are light (0 to 10 mph).
Cold: Between 0° and 40° Fahrenheit during the day, 10 to 20 degrees colder at night.
Cold Snap: Lowers temperature by –10° F.
Downpour: Treat as rain (see Precipitation, below), but conceals as fog. Can create floods (see above). A downpour lasts for 2d4 hours.
Heat Wave: Raises temperature by +10° F.
Hot: Between 85° and 110° Fahrenheit during the day, 10 to 20 degrees colder at night.
Moderate: Between 40° and 60° Fahrenheit during the day, 10 to 20 degrees colder at night.
Powerful Storm (Windstorm/Blizzard/Hurricane/Tornado): Wind speeds are over 50 mph (see Table: Wind Effects). In addition, blizzards are accompanied by heavy snow (1d3 feet), and hurricanes are accompanied by downpours (see above). Windstorms last for 1d6 hours. Blizzards last for 1d3 days. Hurricanes can last for up to a week, but their major impact on characters will come in a 24-to-48-hour period when the center of the storm moves through their area. Tornadoes are very short-lived (1d6×10 minutes), typically forming as part of a thunderstorm system.
Precipitation: Roll d% to determine whether the precipitation is fog (01–30), rain/snow (31–90), or sleet/hail (91–00). Snow and sleet occur only when the temperature is 30° Fahrenheit or below. Most precipitation lasts for 2d4 hours. By contrast, hail lasts for only 1d20 minutes but usually accompanies 1d4 hours of rain.
Storm (Duststorm/Snowstorm/Thunderstorm): Wind speeds are severe (30 to 50 mph) and visibility is cut by three-quarters. Storms last for 2d4–1 hours. See Storms, below, for more details.
Warm: Between 60° and 85° Fahrenheit during the day, 10 to 20 degrees colder at night.
Windy: Wind speeds are moderate to strong (10 to 30 mph); see Table: Wind Effects on the following page.
