Temperatures & Rain Chances

Another round of scattered showers and thunderstorms will develop through the afternoon with stronger storms capable of producing rainfall rates of 1 to 1.5 inches per hour. This may lead to abrupt runoff and possible flash flooding since the ground and soils are saturated in many locations. Periodic waves of showers and thunderstorms are forecast to continue to move into south central, southeastern, and east central areas of New Mexico through the evening.

A Flash Flood Watch remains in effect for southeastern New Mexico through tonight. Remember, a Flash Flood Watch means the weather ingredients necessary for flash flooding are starting to align.

The surge of monsoonal moisture continues today and Friday with repeated rounds of showers with embedded thunderstorms continuing to produce a risk of flash flooding, especially in south central to southeastern areas of New Mexico.

Rainfall amounts will be highest and the coverage will be most widespread through southeastern New Mexico, although showers and storms will continue at times across central and western New Mexico as well.

Active monsoon pattern continues today and Friday before a break Saturday. Another round of showers and storms returns Sunday and Monday, lasting into the middle part of next week.
