Extreme heat across the US in 4 graphics

Unusual March heat has pushed temperatures into record territory in parts of the West. More extremes are expected in the days ahead. While heat is most acutely felt by people exposed to it, graphics and charts convey the scale of this extreme event. Graphics show where temperature records may have been broken, where to expect extreme temperatures next week and what kind of heat to expect in April, May and June. An Associated Press analysis found that roughly a quarter of March heat records at 400 weather stations across the United States may be tied or broken this month.
