BEND, Ore. -- Central Oregonians enjoyed a pleasant -- though anything but hot -- Labor Day Monday, as the Redmond Airport recorded its second straight day of record-cold temperatures.

Redmond reported a low of 26 degrees Monday morning, snapping by one degree the 27-degree mark for Sept. 6, set back in 1961,.

Four other cities in the National Weather Service-Pendleton reporting area tied their records for the date, including John Day and Status Passm, Wash., at 33, Pendleton Airport at 41 and Meacham at 28 degrees.

A freeze warning was allowed to expire Monday morning, as lows at least the next few nights in the Bend area are expected to be above freezing.

Redmond dropped to 29 degrees early Sunday, clipping the old record low for Sept. 5 of 30, set in 1969 (records go back to 1949).

NWS foreacasters in Pendleton issued the warning for midnight to 8 a.m. Monday, saying overnight lows would drop to the upper 20s to low 30s.

"Freezing temperatures may cause damage to tender vegetation and potted plants," the warning said.

"In addition, those sleeping outdoors this holiday weekend should dress warmly and be prepared for sub-freezing temperatures tonight," the weather service added.

Freezing temperatures usually cause damage to vegetation and potted plants.

Most plants that will be affected are some of your vegetable plants or your annuals. Cucumbers, peppers, summer squashes, tomatoes and corn are the most sensitive and vulnerable.

Most annuals are also sensitive, besides petunias, which usually take a light frost without damage.

Experts say you should cover your plants using bedsheets and blankets, as well as using a liquid spray that can protect plants down to 9 degrees Fahrenheit.

If you want plants that will give you color on into winter, nurseries recommend plants such as cabbages, kale, pansies and violas.

If you have hanging plants or potted plants, be sure to bring them inside on such cold nights.
