| episode_narrative | A very moist and unstable airmass was in place over Iowa. South winds at the surface into the mid levels drew precipitable water values were in excess of 50 mm over the CWA with 850 mb dew point values reported at +19 degrees C. A cold front held nearly stationary during the previous few nights to the northwest of Iowa. The front began to move southeast during the day on the 25th, and moved across the state during the evening hours. Thunderstorms from the previous nights convection north and west of Iowa moved into the state during the morning hours. As temperatures warmed during the morning hours, the atmosphere became very unstable. Temperatures rose into the 80s quickly over central Iowa with dew points at the surface in the low to mid 70s. During the afternoon, temperatures in eastern Iowa rose into the mid 90s. With CAPE values over 3000 J/kg and Lifted Indices around -8 C., the thunderstorms re-intensified rapidly. The initial line of thunderstorms produced scattered severe weather in parts of central and eastern Iowa. There were few reports of any hail as the freezing level was 15,100 feet. Gusty winds were common with the stronger storms producing severe winds. Winds as high as 65 MPH were reported in the Hudson area of Black Hawk County. Roof damage was reported on a farm southeast of Hudson. Trees and power lines were damaged in the Tama area by 60 MPH winds. By early afternoon, a second line of thunderstorms developed in western Iowa along the cold front. In similar fashion to the earlier storms to the east, the second line of thunderstorms produced high winds. The high winds were scattered in nature with most damage limited to trees and power lines. Winds broke windows of a house south of Delphos in Ringgold County. As the thunderstorms moved through Central Iowa, lightning struck the National Weather Service office in Johnston. The office took a direct strike with damage reported to some of the equipment in the office. Heavy rainfall was associated with many of the thunderstorms. Rainfall 3 to 5 inches fell in a 2 hour period over Marion County. In the Melcher-Dallas area, 5.26 inches of rain was recorded. The heavy rainfall caused some flash flooding. Being as antecedent conditions were very dry, the flooding was minor and limited to agricultural areas and low rural roads. A few county roads were closed for a brief period of time due to the flooding. As the storms moved through Jasper County, lightning struck a garage and set it on fire. The fire was contained quickly by the volunteer fire department. |
