After several weeks of little-to-no rain, Indiana welcomed some much-needed precipitation over the last several days. While amounts ranged from 1-to-3 inches (except for a few counties in west-northwest Indiana (see Figure 1)), the state is still several inches from recovering from the deficit and relieving most impacts.  The U.S. Drought Monitor this week (based upon data through the morning of Tuesday, June 13th) now has all of Indiana in some category of abnormal dryness or drought (Figure 2).  The driest location is northwestern Indiana where severe drought (D2) is impacting several counties.  Most of northern and some central Indiana counties are in moderate drought (D1) with southern Indiana Abnormally Dry (D0).  After the additional precipitation that fell on June 13th along with what is forecasted (Figure 3) through next Thursday, Jun 22nd, there is a strong probability that drought will not worsen for much of the southern half of[Read More…]

The last several weeks have seen very little precipitation across Indiana.  Figure 1 illustrates how much was received compared to the climatological normal amount from May 9 through June 7.  The entire state received amounts less than normal (where normal would be 100 percent on the map) with central and northeastern Indiana having received less than 25 percent of normal amounts.  This has resulted in browning lawns, lowered ponds and streams, and most vegetation starting to look stressed.  Why is this happening and how long will it last?     While the El Niño – Southern Oscillation (ENSO) global teleconnection pattern is shifting from the La Niña phase (that has been around for the better part of three years, now) to the El Niño phase, it is difficult to attribute this dryness to ENSO.  Historically, ENSO phases have had weaker correlations to temperature and precipitation in the Midwest – particularly[Read More…]
