LAKE COUNTY, Calif. — The National Weather Service said storm systems are expected to move through Lake County this week, bringing showers and frosty temperatures.

Forecasters predict a “weak, fast moving system” will move through the area early Tuesday, bringing some wind plus chances of rain on Tuesday night.

That will be followed by another system on Wednesday and Thursday that the forecast said could give southern Mendocino and Lake counties “light sprinkles” totaling less than a quarter of an inch.

Late Thursday and early Friday morning, the National Weather Service forecasts frost throughout Lake County, with nighttime temperatures into the 30s.

Temperatures throughout the week and into Monday are forecast to range from the low 50s to the low 60s during the day and the low 40s at night. After nighttime temperatures dip into the 30s on Thursday and Friday, they will inch back up into the 40s during the weekend.

Rain will return to the forecast on Sunday and Monday, but so far rainfall totals haven’t been estimated.
