As October comes to an end, a change in the weather is on the horizon for the Bay Area. The National Weather Service has forecasted rainy and cold conditions to sweep through the region. Meteorologist Dial Hoang shared that a couple of weather systems are on their way, with the second one potentially being even colder.

The first system, a low-pressure trough moving down from the northern Pacific Ocean, is set to bring rain on Wednesday night or Thursday morning. While higher elevations may see up to half an inch of rain, most parts of the East Bay and South Bay can expect only a few hundredths of an inch. Areas close to the water could see around a couple-tenths of an inch.

Snow is also in the picture, with forecasts predicting 3 to 6 inches in elevations above 6, 000 feet, starting Wednesday afternoon. The National Weather Service has issued a winter weather advisory for these higher elevations, starting at 11 p. m. Wednesday and lasting through 5 p. m. Thursday.

The weather for trick-or-treaters on Thursday night is expected to be mostly dry, but it will be cool, with temperatures in the mid- to low 60s. Another system is set to arrive late Friday, bringing more rain and colder temperatures. Overnight lows are expected to dip into the low and mid-40s.

After the chilly spell, temperatures will start to rise again by Sunday, climbing back into the low 70s by Monday. This shift in weather is quite different from the scorching heat of early October, which saw temperatures in the 100s for the longest and hottest heatwave since 1980.
