Heat Continues as Record Early Wave Hits U.S. Southwest

A record-strength March heat dome boosted temperatures by 4.7°F, breaking records in 14 states and impacting hundreds of weather stations, experts said.

  • Data from dozens of weather stations show over 170 locations from California to Pennsylvania tied or set new March records as four reporting stations in Arizona and California hit 112 degrees on Friday.
  • Meteorologists say a stalled ridge of high pressure — a record-strength heat dome for March — parked over the West and trapped hot air, while the jet stream remained stuck westward, prolonging the warmth.
  • Federal station data show a surge of record breaks across hundreds of sites, with the National Center for Environmental Information reporting at least 479 weather stations and another 1,472 daily records shattered.
  • Meteorologists say the dome is moving east and will push high temperatures across the Plains, bringing 90s by Wednesday over the southern and central Plains and lasting until the middle of next week as April starts.
