Temp & Precip Outlook

Look Before You Lock!

A few strong storms will be possible in the Clayton area this afternoon and evening.

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.

Record Heat continues across western and central NM on Tuesday. Slightly cooler temperatures with higher storm coverage across northeast and east central NM.

A narrow corridor of instability will overlap with sufficient deep layer shear near the Sangre De Cristo Mountains Tuesday afternoon. This will be in the region where a surface front intersects the terrain within a favored upslope region. Marginally severe hail and strong to severe wind gusts will be possible.

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.
