Temp & Precip Outlook

Look Before You Lock!

Today will be very hot with high temperatures generally 10-15 degrees above average. Record highs will likely be broken throughout much of western and northern New Mexico.

Widespread moderate to major heat risk is expected across New Mexico today due to high temperatures in the mid 90s to mid 100s. Slightly cooler temperatures across northeast and east central New Mexico Tuesday will help reduce the heat risk to minor to locally moderate. However, moderate to major heat risk will continue across the rest of the state.

Unusually hot temperatures will persist through early week. Chances for storms will be lower through early week and generally favor the western and northern mountains.

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.
