Wednesday continued the streak of somewhere in the state picking up significant rainfall with numerous rounds of slow moving showers and thunderstorms impacting the state. Even with these many rounds of storms, there are still parts of Iowa below average for June as shown by the featured map. The map presents RADAR-based estimates from NOAA's MRMS project compared with a simple grid of precipitation climatology. Any areas shown in tan to orange have a June to date total below average. The most significant deficits can be found between Cedar Rapids and Iowa City of around 2 to 3 inches. Additional rounds of storms are in the forecast to close out June, but they again will be highly variable with isolated areas picking up the drought busting totals.
