Even the climate models are confused by this year’s weather. When the August monthly outlook was released (July 31st; national Climate Prediction Center) it showed significant confidence that August would have below-normal temperatures and below-normal precipitation. However, the shorter-range outlooks (that update daily) the last few days, seem to contradict that prediction. Whether it is the 6-10-day (August 20-24), the 8-14-day (August 22-28; side-by-side figure) or the 3-4-week experimental outlooks (August 25 – September 7), all are predicting significant confidence for above-normal temperatures and precipitation. Given the recent development of drought conditions across the state, these climate predictions (particularly for precipitation) are strongly desired! Will those climate outlooks verify? The current 7-day quantitative precipitation forecast is indicating very little precipitation over the next seven days. That is slightly below normal for this time of the year in Indiana (side-by-side figure). It is a roller coaster ride, it seems.
