Temperatures are expected to fall to lower than coldest temperatures observed, thus far, this season both Thursday morning and Friday morning. This means that a hard freeze is expected across most of the east side, while some west side valleys will also experience their first freeze of this fall season. Other west side valleys will see their first killing frost of the season. Please note that the above values are for Thursday morning. Damaging temperatures will begin Wednesday night in some areas and temperatures will be colder Friday morning in other areas. Take precautions by harvesting, covering, or bringing in tender vegetation. Also take precautions to prevent freeze damage to irrigation systems in areas where freezing conditions are likely.
