Episode Narrative An occluded/occluding surface low pressure system slowly worked its way into western and southwest Iowa during the morning and afternoon of the 25th. Given its location, Iowa was situated north of the warm front, which was much further south into central Missouri. Even so, the environment was cool yet fairly saturated in the low levels with temperatures in the low to mid 70s and dew points in the mid to upper 60s.
Low level flow was up over the occluded front, providing additional lift, within an environment of around 1000 J/kg MUCAPE, effective shear up to around 40 kts, lifted condensation levels approaching 500 m at times, and plenty of low level 0-1 km storm relative helicity in excess of 200-300 m2/s2. All in all, it was a ripe day for general moderate to heavy rainfall, funnel clouds, and weak landspout tornadoes. The majority of the action revolved around heavy rainfall that totaled in excess of 3 inches in many locations, but also involved multiple funnel cloud reports and a lone brief tornado near Delphos in Ringgold County.
Event Narrative This tornado touched down in the hamlet of Delphos with tree debris being tossed around. A rather diffuse funnel for much of its existence, very little damage occurred with this tornado. The event was captured on video by a few different storm chasers.
