Divided Temperature Across the Midwest

To the west, Missouri, Iowa, and southern Minnesota, all experienced average temperatures that were 1°F to nearly 9.5°F above normal (Figure 1). Emmet County, located in northern Iowa, recorded an average temperature of 24.1°F. This was 9.3°F above normal for the week. Near normal temperatures were observed through Illinois, Indiana, southwest Michigan, and north-central Ohio. In northern Minnesota, Wisconsin, Michigan, and eastern Kentucky, average temperatures ranged from 1°F to just over 8°F below normal (Figure 1). Charlevoix County, located in northern Michigan, averaged 16.6°F (6.6°F below normal). The average temperature in Bayfield County, Wisconsin, located in northern Wisconsin, was 2°F (8.1°F below normal). Much of the Midwest observed minimum temperatures that were 1-10°F below normal, with isolated locations reaching 15°F below normal (Figure 2). The only exceptions to this were southern Minnesota, Iowa, and Missouri, where minimum temperatures ranges 1-5°F above normal. There were 12 low minimum and 10 low maximum daily temperature records broken or tied (Figure 3). The maximum temperatures through these three states ranged from 1-8°F, with isolated locations exceeding 10°F above normal (Figure 4). There were 12 high maximum and 7 high minimum daily high temperature records broken or tied this week, most occurring in southern Minnesota, Iowa, and Missouri (Figure 5).

Much of Ohio River Valley Receives Above Normal Precipitation, Again

After above normal precipitation last week, another week of above normal precipitation was observed across the southern Midwest. Southern Indiana and Ohio received 0.2-1.5” of precipitation (Figure 6). Heavier precipitation fell in Kentucky where most of the state received 1-3", and isolated locations receiving 4”. Southern Indiana received 100-175 percent of normal precipitation (Figure 7). Kentucky received 100-400 percent of normal precipitation. Clay County, Kentucky, received 2.72” of precipitation, which was 1.78” above normal. There were 46 daily precipitation records broken or tied, most concentrated through Kentucky (Figure 8).

Most of the Snow Stays North

While precipitation was above normal in the southern Midwest, it all fell as rain. Snowfall this week was confined to the northern stretches of the region. In Minnesota, 0.1-10” of snowfall was recorded (Figure 9). Yellow Medicine County, Minnesota, recorded 10” of snow, which was 8” above normal for the week. Lake effect snowfall totals in northern Indiana ranged from 0.01-3.5” (3.5” fell in South Bend, Indiana). Additional lake effect snow fell in northern Michigan where Chippewa County received 16.2”, which was 9.2” above normal. There were 12 daily snowfall records broken or tied this week (Figure 10).
