Many Days Till an Inch

Posted: 02 Nov 2022 05:32 AM

Using NOAA MRMS precipitation estimates, the featured map presents the number of days one has to go back in time before accumulating at least an inch of precipitation. The areas of extreme dryness since September and even earlier are readily apparent. It is remarkable to see how much of the state is at least in the brown color, which represents at least 50 days. More isolated spots in far northwestern Iowa are in the 70 plus day range! The good news is that the forecast continues to be very bullish for significant rainfall over Iowa over the coming seven days, but extreme northwestern Iowa looks to miss out on the highest totals.
