SAN DIEGO (FOX 5/KUSI) — At long last, San Diego received its first significant rainfall — and snow — in months over the weekend. The precipitation, which was brought on by a cold low pressure system, was a much-needed break from stubborn arid conditions primed for potentially erratic fire behavior.

Most San Diegans woke up Monday to puddles or downpours, a welcome respite from the 40-plus day drought the region had experienced. The county's first significant rainstorm of the season brought totals Monday ranging from a quarter to half an inch near the coast to more than an inch in the mountain slopes, according to the National Weather Service.

The National Weather Service says there is a chance of thunderstorms into Monday, while there is a chance that rain may hang around San Diego until Wednesday. Maximum rain rates could exceed 0.3 inches per hour Sunday,

Depending on where you reside in San Diego County, you may need your rain jacket or snow boots Sunday based on the weather forecast.

Overnight, isolated lightning strikes were reported, primarily over coastal waters and nearby land areas, but thunderstorm chances were expected to decrease by Monday morning.
