Heat and active weather is in store this week as we sit on the edge of a building heat dome. From Sunday onward, highs in the 80s to 90s and heat indices into the 90s and low 100s will be possible, especially south of Interstate 80. North of Interstate 80, periodic chances (20-40%) for isolated showers and thunderstorms may help limit temperatures.
A period of active and hot weather is expected from Sunday through the middle of the week. Increasing temperatures and humidity will result in heat index values approaching 100, especially for areas south of I-80. Chances for showers and storms will also increase north of I-80.
Hot weather is expected through much of next week. Peak heat indices in the mid 90s to lower 100s will lead to an increased risk for heat related illnesses for those working or recreating outside.
