A cold front is coming to San Diego County this week, which will bring cloudy skies, a drop in temperatures, light rain, and possibly some snow in the zone's highest areas.

It is estimated that weather in the region will change on Tuesday when a high pressure system moves east and a low pressure system moves forward, according to the National Weather Service (NWS).

The same system could bring some humidity this week, with isolated showers in several regions of the county. However, these rains are not expected to be serious, NWS said.

In San Ysidro, there is a 67% chance of rain, while the chance is 62% in the city of San Diego.
