Hazardous Heat

A few strong to severe storms are possible over northeast NM through this evening where large hail, damaging winds, heavy rainfall, and frequent lightning strikes may occur. Any storm across the entire region will be capable of producing strong outflow winds.

A near-total lunar eclipse will occur this evening (96% totality). The greatest eclipse will occur at 10:13 PM MDT. Look for the moon low in the southeastern sky. Cloud cover will make viewing difficult in some areas.

A few strong to severe thunderstorms are expected this afternoon and evening near and east of the Sangre de Cristo Mountains. Large hail and damaging winds gusts are the main concerns between 2pm and 10pm MDT.

The greater storm coverage will focus over eastern NM through Friday then over western NM on Saturday. A few storms will be capable of producing rainfall amounts greater than one inch.

Above normal temperatures will continue through next week. Storm coverage and rainfall intensity will peak through Monday.

Heat can escalate quickly. Warm temperatures can quickly become dangerous. Heat is one of the most deadly weather hazards - don't underestimate it. Never leave people or pets alone in a car. Drink plenty of water, even if you don't feel thirsty. Wear loose-fitting, light-colored clothing. Spend time in air conditioning and in the shade.
