The most notable feature in regional analysis was Tropical Storm Ida that was centered over west central Mississippi around 20z on August 30th. Locally, what was a cold front had become more of a diffuse stationary boundary extending from central Indiana through portions of Illinois and into central Missouri. Light northerly flow settled in behind the front with gradually decreasing moisture. Surface dew points dropped from the low-70s near the I-70 corridor to the mid and upper 60s along the MO/IA border. Easterly flow at the northern fringes of the tropical system somewhat enhanced the convergent potential along the boundary. This, along with uncapped SBCAPE of 2000-3000 J/kg and low level lapse rates around 7 C/km gave way to convection from late morning into the afternoon hours. PWATs along and ahead of the boundary remained near 2 inches with weak flow and effective shear of around or less than 20 knots. Slow movement and abundant moisture made it possible for heavy rain to develop which lead to localized flooding through the afternoon and evening hours. As storms became cold pool dominant and instability fell off, coverage of the convection decreased.
