ALBUQUERQUE, N.M. (AP) — Forecasters with the National Weather Service said Tuesday that New Mexico is in for a stretch of hot weather.

They warned that a heat advisory may be needed for parts of eastern New Mexico from Roswell up to Clovis and Tucumcari later this week. Temperatures across the plains are expected to reach the triple digits while parts of the Rio Grande Valley will see highs well into the 90s.

An upper level pressure system is to blame for the high temperatures, but forecasters say a front that is expected to push into the state could bring with it thunderstorms and moisture for the weekend and take the edge off the heat wave.

New Mexico also was inundated with smoke from wildfires burning in neighboring Arizona. Air quality advisories were issued Monday and Tuesday due to the haze that was blanketing parts of the state.
