Snow in the Desert
To simplify the die roll, I have combined snow and rain together as precipitation. The type of precipitation is your decision. I would suggest some rhyme or reason to make it believable, but ultimately it is up to you. That said, a blizzard in the desert would be an exciting story point for your players to explore.
Category 5 or a Slight Drizzle
So you rolled your die and got wind or precipitation. Now what? Is it a light rain or a hurricane? The choice of the kind of weather your get after the roll is entirely up to you. Keep in mind, while the choice of intensity is your decision, the rules on what happens because of the weather will be the same.
Note: If you want to increase, decrease, or modify the condition’s that the weather brings, feel free. These are what I chose based on the weather I have been affected by.
The Forecast Calls for Debuffs
While most weather can be said to be harmful or give a “debuff,” in reality, the weather could debuff only enemies making it a positive for your players. After all, Debuffs are only debuffs if they affect you.
The exception to this is sun. In this guide sunny days are regular days that do not confer any changes.
