Hotter temperatures are continuing across New Mexico this week as high pressure strengthens over the Southwest, with highs reaching the 90s to triple digits and a fire weather watch now in view. East central and northeast New Mexico get a brief cool-down this afternoon and evening, but most of the state stays well above average.
Temperatures will climb above average through midweek as the heat settles in. The backdoor cold front moving through eastern New Mexico this morning has already brought breezy winds, and that cooler pocket will be limited to east central and northeast New Mexico while the rest of New Mexico remains hotter.
New Mexico Heat Through Midweek
The strongest signal in the forecast is the heat itself. High pressure over the Southwest is building into Wednesday, and that keeps temperatures elevated across most of New Mexico rather than allowing a broader cool-down.
For residents in the cooler part of the state, the break is temporary. East central and northeast New Mexico will stay cooler through the afternoon and evening because of the backdoor cold front, while the rest of New Mexico holds in the warmer pattern.
Southwest High Pressure Builds
The same setup that pushes temperatures into the 90s to triple digits also keeps the week on a fast-moving weather cycle. Isolated afternoon and evening thunderstorms will develop each afternoon during the first half of the week, giving the state a brief window for storm activity before the pattern shifts again.
Heading into Wednesday, more moisture will move into the region as high pressure builds across the region. That change opens the door to isolated to scattered showers and storms during the second half of the week, a wider spread than the earlier daily storm chance.
Monsoon Moisture Later
The week begins with heat and breezy winds in eastern New Mexico, then turns toward more moisture later in the week. For readers in most of New Mexico, the practical shift is from a dry, very warm stretch early in the week to a more active late-week pattern with shower and storm chances.
The forecast does not say whether the expected heat or storms will trigger any fire weather watch, but the combination of triple-digit heat, breezy winds and later moisture leaves the state moving through two different weather regimes in the same week.
