Sparks police arrived to find more than 100 people fleeing a gathering near Pyramid Way and Greenbrae Drive.
High pressure will build slowly over the region through this week. Freezing temperatures are possible in the morning hours through the weekend, especially above 5000', with patchy late night/early morning fog. Expect a slow warming trend, with chilly mornings, and mild to warm, sunny afternoons. Valley floor 80s are likely again this week.
A barbecue left on caused the deck to catch fire and that burned into the attic.
The incident happened near Shopper's Square.
