The featured map presents May to date precipitation departures courtesy of PRISM. There is plenty of red (below average departures) to be found on the map. Outside of the rainfall events of last weekend, there has not been much to speak of for rain during May. Much of Iowa is surviving from the very wet April and the periods of reduced water demand like what was found this week with the cool and cloudy conditions. The precipitation forecast for the rest of May is not that bullish and temperatures will be increasing, which will start to materialize impacts over the driest parts of the state this May. For this time of year, it roughly takes about an inch of rain per week just to keep up with climatology, so departures can rapidly build when we get dry periods during the wettest portion of the year!
