Though temperatures trend down slightly today, triple digit heat persists for the lower Rio Grande Valley and portions of east central NM. Stay hydrated, limit strenuous time outdoors in the afternoon, use air conditioning and wear light-weight light-colored clothing.

Scattered to numerous showers and thunderstorms will develop this afternoon and continue through the night. Storms will be capable of heavy rainfall, gusty winds and small hail, though a few storms across northeast NM may become strong or severe with large hail and damaging wind gusts.

A Marginal Risk of severe thunderstorms exists across northeast and east central NM on Friday. Storms moving off the Central Mountain Chain over eastern NM will be capable of large hail and damaging wind gusts. A few strong to severe storms are also possible today and Thursday across northeast NM.

Daily rounds of showers and thunderstorms will develop over northern and central New Mexico. Some will produce locally heavy rainfall and flash flooding. Triple digit heat will be observed for many lower elevation locations.

Never, never, never leave children, disabled or elderly adults, or pets in parked, unattended vehicles! Studies have shown that the temperature inside a parked vehicle can rapidly rise to dangerous levels for people and pets. Leaving the windows slightly open does not significantly decrease the heating rate. The effects can be more severe on children because their bodies have not developed the ability to efficiently regulate internal temperature.
