It might be a good idea to cover your tomato plants tonight, especially if you live in the northern Red River Valley.

A cold front that arrived in the Red River Valley on harsh northwest winds late morning Monday is expected to drop temperatures to the low 30s by early Wednesday, especially north of N.D. Highway 200, said Vince Godon, a meteorologist with the National Weather Service in Grand Forks.


The most likely areas to develop frost by Wednesday morning are Devils Lake, Cando and Langdon, N.D., where temperatures could dip into the upper 20s.

While the winds were expected to weaken overnight Monday, the front will continue to move southeasterly, with Thursday morning temperatures in the low 30s in the Bemidji, Park Rapids and Wadena, Minn., areas, Godon said.

Grand Forks could approach 32 degrees overnight tonight, with some low-lying rural areas at risk of developing some frost.

"You might want to cover your tomato plants. They're pretty sensitive in the mid-30s, too," Godon said.

The Farmers Almanac indicates the average first day of frost in Grand Forks is Sept. 27.

Last year, the three coldest temperatures recorded in September in Grand Forks were 39 on Sept. 8 and 16, and 34 on Sept. 18.

Daytime highs should be in the mid-60s today and mid-50s Wednesday.

Warmer temperatures should return later in the week. Highs on Thursday and Friday should be in the mid-60s. By the weekend, temperatures should climb into the low 70s.
