A cold October weather pattern spilled into the first half of November with milder conditions during the latter half of the month, Figure 1. Preliminary data indicate the average statewide November temperature was 40.3°F, 3.5 degrees below the long-term average. It was the second consecutive November with below normal temperatures, Figure 2, and sixth cooler than average month for the year, Figure 3. There were numerous reports of record low temperatures established across the Midwest during the week of November 11-16, Figure 4. Missouri’s coldest temperatures occurred on November 12-13, Table 1.

Preliminary precipitation data indicate an average statewide total of 2.83 inches, only 0.06” below the long-term average, Figure 5. It was the third month with below average precipitation for 2019, Figure 6. The Jan-Nov 2019 statewide average precipitation was 52.23 inches, making it the 5th wettest Jan-Nov on record, Figure 7.

According to monthly radar estimates, Figure 8, precipitation amounts increased moving southeastward through the state. Lightest amounts occurred over far northwestern Missouri where less than 1-inch was reported and 1-2 inches were common across the rest of northern Missouri and west central sections. Much of central and east Missouri received 2-3 inches and 3-5 inches were common over southern sections, generally along and southeast of I-44. There were numerous reports of 6-7 inches across far southern Missouri and in the Bootheel. A CoCoRaHS observer near Ava, MO, in Douglas County, reported 8.19 inches for the month.

A significant snow event impacted parts of central and east central Missouri on November 11-12, Table 2.
