Major Storm System to Bring Severe Weather to Borderland Through Weekend

A major storm system will bring an extended period of active weather to the Borderland starting Wednesday, with heightened risks for severe thunderstorms, heavy rainfall and flooding through the weekend, according to KVIA.

The system spinning off the California coast, combined with an upper-level ridge positioned to the southeast, will funnel moisture into the region, particularly across Arizona and the western portions of the Borderland. Storm chances will increase Wednesday, especially along and west of the Continental Divide. A Marginal Risk for severe weather is in place, with some storms capable of producing large hail and damaging wind gusts.

Thursday will mark the most active day of the pattern. A significant surge in moisture will accompany the incoming system, creating abundant moisture for heavy rainfall. The combination increases the potential for flooding, strong thunderstorms, large hail and damaging winds through Friday. Areas receiving repeated rounds of thunderstorms could experience localized flooding.

Another upper-level system will arrive early Saturday, providing additional energy for that day's storms. Rain and thunderstorm chances will continue with another possibility for severe thunderstorms and flooding. By the end of the weekend, the upper-level system will be absorbed into the main flow, allowing drier conditions to spread gradually from west to east.

Looking ahead to early next week, a strong cold front could move through the region Monday into Tuesday, bringing a return of windy conditions and a noticeable weather change.
