Tight Ames Gradient

Yesterday's featured map illustrated the splotchy nature of the rainfall on Monday over Polk County. The featured map should have been moved one county north over Story County to show what happened there on Monday, particularly over Ames! Today's featured chart atones for that omission and attempts to overlay a semi-transparent MRMS estimate of precipitation along with available 24-hour CoCoRaHS reports for Ames. A remarkable gradient from just one hundredth of an inch over far western Ames to something approaching two inches just a few miles east near Grand Avenue. So this situation again reminds us of the eminent IEM Seminar titled How much did it rain in Ames on 25 June 2010?
