Widespread frost seen along Red River Valley
GRAND FORKS. - Uncovered tomatoes had a rough morning in the Red River Valley.
Widespread frost hit much of eastern North Dakota and northwest Minnesota this morning, with the temperature at Grand Forks International Airport dipping to a chilly 29 degrees, according to the National Weather Service.
The low temperature at Fargo's Hector International Airport was 34 degrees at about 7:30 a.m., and some metro-area residents had to scrape their windshields.
Frost can form on or near the ground even if the reported temperature is above freezing, because the air temperature is measured at 6 feet above ground level, the weather service said.
Frost was widespread in the northern Red River Valley and spotty in the southern half around Fargo-Moorhead and Wahpeton-Breckenridge, said Vince Godon, meteorologist at the weather service in Grand Forks.
Fargo-Moorhead had sunny skies this morning, and today's high is expected to be around 60, Godon said.
From 1971 to 2000, the average day for the first fall freeze was Sept. 27 in Fargo and Sept. 20 at the Grand Forks airport, according to the weather service.
