Some standing water this morning in low spots but otherwise surprisingly little evidence of heavy rain, flooding. Precip associated first with warm advection convection followed by pre-cold frontal convection. Synoptics were very favorable for severe wx last 24 hours given 70F+ dew points, high bulk shear, and strong upper air dynamics. 24-hour 3.23" total precip is new record for site for 7 year POR (since JUN 2008). Interestingly, this matches almost exactly the new NOAA Atlas 14 recurrence interval of just under 7 years for a 3.23" 24-hour event.
