July was drier than normal across much of the state. The statewide average precipitation was 2.32 inches, or 65 percent of normal. Only the Southwestern Division was above normal for the month. The average precipitation in that division was 3.37 inches, or 125 percent of normal. The Central Division had the least percent of normal with an average of 1.71 inches, or 43 percent of normal. The South Central Division had the lowest average at 1.53 inches, or 46 percent of normal. Year-to-date averages are still above normal in all except the Northeast and East Central divisions. The greatest monthly precipitation total for a National Weather Service (NWS) Coop station was 7.89 inches at Richfield 1 NE, Morton County. The greatest monthly total for a Community Collaborative Rain, Hail and Snow (CoCoRaHS) station was 11.69 inches at Overland Park 3.3 S, Johnson County. The highest 24-hour totals: 6.20 inches at Overland Park S87th, Johnson County, on the 27th (NWS); 6.34 inches at Lenexa 2.0 NE, Johnson County (CoCoRaHS).
Temperatures were warmer than normal statewide, with highest temperatures in the middle of the month offset by a cooler-than-normal start and end to the month. Statewide temperatures averaged 79.8 degrees F or 1.2 degrees warmer than normal. The West Central Division averaged closest to normal with an average of 78.0 degrees F, or 0.7 degrees warmer than normal. The North Central Division had the greatest departure with an average of 80.7 degrees F, which was 1.7 degrees warmer than normal. The warmest reading for the month was 111 degrees F at the Salina Airport, Saline County, on the 22nd. The coldest reading was 48 degrees F, recorded at Tribune 1W, Greeley County, on the 1st. Despite the warm temperatures, there were no record high maximum temperatures during the month and only 11 record high minimum temperatures. On the cold side, there were 2 new record cold maximum temperature in July and two new record low minimum temperatures. None of the temperature records set new records for the month of July. All divisions had high temperatures reach 100 degrees F or more.
Severe weather was limited in July, with most of the events in the form of hail and high winds. There was one reported tornado, which is less than the 1950-2016 average of 5 tornadoes in July. In addition to the tornado, there were 17 hail reports, and 38 high wind reports. The most damaging event of the month was the flooding in Johnson County, following the heavy rains on the 27th. Catastrophic flooding was reported along several local streams, including Indian Creek in Overland Park and Tomahawk Creek in Leawood. Numerous swift water rescues were performed across the city and surrounding areas.
The lower-than-normal precipitation with warmer-than-normal temperatures resulted in an expansion of the abnormally dry conditions and the return of moderate drought in parts of the state. The August outlook calls for a slightly increased chance of wetter-than-normal conditions the across the southwest portion of the state, with equal chances of above- or below-normal precipitation across the remainder of the state. This is coupled with higher chances of below-normal temperatures. The much cooler-than-normal temperatures in the beginning of August will reduce some of the evaporative demand.
