| Episode narrativeepisode_narrative | A weak cold front moved southeast across Iowa early on the 4th and had become stationary east-west to the south of the state. The thermal gradient increased during the day and moisture pooled along the front by evening. The atmosphere became quite unstable by late afternoon with temperatures reaching well into the 90s south of the front, and dew point readings rising into the low 70s along the front. CAPE was in the 3000 to 4000 J/kg range by mid to late evening with lifted indices in the -5 to -10 C range. Precipitable water values increased to near 2 inches along the front as the 850 mb jet increased to 30 to 40 kts. Downdraft CAPE was in the 700 to 1000 J/kg range and available CAPE in the -10 to -30 C layer of the atmosphere was 400 to 600 J/kg. The freezing level was relatively high, in the 13,000 to 13,500 foot range, however with effective shear in the 50 to 70 kt range, plenty of dynamic energy was available. Thunderstorms developed initially over southeast Iowa into Missouri and produced large hail. Quarter to golf ball size hail fell in Davis and Appanoose Counties. As the night progressed, the first round of thunderstorms moved southeast of Iowa. By midnight, the second round of storms developed over southern Iowa. Though there was no severe weather with this round, heavy rainfall occurred. A third round moved through during the predawn hours, producing very heavy rainfall of 2 to 3 inches per hour. Total rainfall of 3 to 6 inches was common over south central into part of southwest Iowa. This resulted in flash flooding with numerous highways closed by high water. Evacuations took place in the south of Lamoni as waters rose. Water rose quickly in the middle fork of the Grand River, scouring out the highway on the U.S. 169 bridge south of the 10 mile post marker. Following the flash flooding, areal flooding took places over parts of south central into southwest Iowa for about 24 hours. |
