Ramsey County Multi-Hazard Mitigation Plan, 2018 <br /> <br />Page | 83 <br /> <br />In Ramsey County, cold winter weather can have severe or fatal impacts. Hypothermia occurs when the <br />core body temperature drops below 96° F. Anyone who is exposed to severe cold without enough <br />protection can develop hypothermia. Frostbite occurs when skin tissue and blood vessels are damaged <br />from exposure to temperatures below 32° F. It most commonly affects the toes, fingers, earlobes, chin, <br />cheeks, nose, and other body parts that are often left uncovered in cold temperatures. The NWS issues <br />“Extreme cold” warnings when it feels like -30° F or colder across a wide area for several hours. <br />Extreme cold watches are issued a day or two before the conditions are expected. <br />Medical costs related to extreme heat and cold can be enormous: in 2005 the total was $1.5 billion <br />nationwide, or more than $16,000 per patient (Union of Concerned Scientists, 2009). <br />Below zero temperatures occur almost every winter in Minnesota. January is the coldest month, with <br />daytime highs averaging 20° F and nighttime lows averaging 2° F. However, these averages do not tell <br />the whole story. Maximum temperatures in January have been as high as 61° F and minimums as low as <br />36° F below zero. <br />Extreme cold temperatures affect the county nearly every year. Extremely cold air settled over <br />Minnesota on January 31st of 1996, and remained entrenched through February 4th. A new record low <br />temperature for Minnesota was set in the town of Tower on February 2, 1996, at -60° F. Numerous <br />record low temperatures were set during the period at St. Cloud, Rochester and the Twin Cities. <br />Minneapolis/St. Paul set 3 new record low temperatures as well as recording the 2nd coldest day on <br />record on February 2, 1996. A mean temperature of -25° F was measured that day with a high of -17° F <br />and a low of -32° F in the Twin Cities. This was within 2 degrees of tying the all-time record low <br />temperature set in the Twin Cities and the coldest temperature recorded this century. Many central and <br />southern Minnesota locations set new record low temperatures the morning of the 2nd. The Governor <br />closed all schools that day. <br />In February of 2014, nearly all of Minnesota was between 10-15° F colder than normal (1981-2010 <br />period) (High Plains Regional Climate Center, 2014). The winter of 2013-2014 was the sixth coldest on <br />record in Minnesota (The Weather Channel, 2014), with schools in the Twin Cities canceling 5 times in <br />January due to dangerous wind chills. It was the coldest winter in the Twin Cities in 35 years, with an <br />average temperature for December-February of 9.7° F (MN DNR, 2014). Many areas in the state also <br />experienced higher than average precipitation through the winter and spring months. <br />Extreme Cold History in Ramsey County <br />January is the coldest month on average in St. Paul, with an average low of 6° F. The lowest temperature <br />ever recorded in the city occurred in February of 1996, when it fell to -32° F. December and January are <br />the snowiest months, with December averaging 11 inches and January averaging 12 inches of snow <br />(Intellicast, 2018). <br />According to the NCEI, in January of 2018, wind chills near -35° F occurred, resulting in 1 death. A man <br />was found in St. Paul who had died from exposure. <br />In December of 2016, a woman froze to death in St. Paul, outside of her apartment building when the <br />wind chill dropped to -19° F.
