Northern KELOLAND has already had areas of frost; Aberdeen fell to 31 degrees last Thursday morning. The chill will move into southeast KELOLAND Monday night as temperatures fall to the low and middle 30s. The cold temperatures will give a chance for frost in eastern KELOLAND.
The frost is just a week or two ahead of schedule, as most areas don't get their first frost until the last week of September or first week of October.
At the moment, a hard freeze will be tough to come by. A typical hard freeze is when the temperature falls to 27 degrees or colder for a period of at least three hours. While there may be communities that fall to the 20s Monday night, it doesn't look like they should be that cold for long.
Regardless, if you have plants you want to keep going this fall, now is the time to take action and cover them.
