El Paso, Texas, had a Monday morning low of about 65 degrees, with a sunny afternoon expected to reach 93. The calm opening will not last long: thunderstorms and a potentially serious flood threat arrive Tuesday afternoon and could continue through Wednesday evening.

Quiet Monday Before Storms Move In

Monday should stay sunny and mostly dry, with light and variable winds and a high near 93. Monday night temperatures drop to about 70.

Showers and thunderstorms become likely after 1 p.m. Tuesday, according to the National Weather Service El Paso. The latest outlook sharpens the timing and risk described in Hoodline's Sunday forecast, which first flagged the midweek storm pattern.

Flood Watch Covers Tuesday Afternoon Through Wednesday

A Flood Watch is in effect from Tuesday afternoon through Wednesday evening across El Paso and surrounding parts of Far West Texas and southern New Mexico. Repeated thunderstorms could send runoff into arroyos, low-water crossings, rivers and poor-drainage areas, with the heaviest rain potential expected Tuesday night into Wednesday morning.

The National Weather Service says a narrow band of storms could produce more than 3 inches of rain in six to 12 hours, although the exact location remains uncertain. The Wednesday morning commute could be affected, so drivers should avoid flooded roads and never attempt to cross water-covered low-water crossings.

Cooler, Wetter Conditions Follow

Wednesday will be notably cooler, with showers and thunderstorms. Thursday brings a high near 80 with a 50% rain chance, while Friday reaches about 81 with additional showers and storms possible.
