ST. PAUL, Minn. (AP) — Bigfork in northern Itasca County is now the holder of Minnesota's record for lowest barometric pressure.
The state climatology office says after consulting with the Duluth National Weather Service office, the lowest pressure recorded during this week's windstorm was 28.21 inches. That record was set at 5:13 p.m. Tuesday at Bigfork.
The climatology office says that pressure reading resulted after the measurement was adjusted for true mean sea level pressure.
Minnesota's old record for minimum pressure was 28.43 inches on Nov. 10, 1998, at both Austin and Albert Lea.
Earlier, the National Oceanic and Atmospheric Administration said the storm that battered the nation's midsection had a pressure reading Tuesday that was among the lowest ever in a non-tropical storm in the mainland U.S.
