Drought Conditions Ease in Indiana

Drought Conditions Ease in Indiana
Updated on Sunday, July 1, 2007
Next Scheduled Update on Thursday, July 5, 2007
Rainfall of 1 to over 3 inches fell in much of Indiana since Friday, June 22.  Western Indiana was especially favored while portions of eastern Indiana saw little or no rain. 
The June 26th release of the U.S. Drought Monitor indicated adnormally dry conditions (D0) in much of Indiana with moderate (D1) to severe drought (D2) conditions in portions of eastern Indiana..
Because of a significant surplus of rain from September 2006 to March 2007, drought conditions have not significantly impacted groundwater levels.  However, soil  moisture deficits remain and stream flow is below seasonal normal..

Agricultural Impacts:
Rainfall from June 22nd through the 29th has improved crop conditions in the state of Indiana. The table below is a summary of statewide conditions for selected crops, the week ending July 1. This data is courtesy of the USDA National Agricultural Statistics Service (NASS) at http://www.nass.usda.gov
Very Poor
Winter Wheat
The following excerpt is from the USDA’s Indiana Crop Weather for the week ending July 1, 2007:
“Scattered showers and pop-up thunderstorms moved across portions of
the state during the week, according to the Indiana Field Office of
USDA’s National Agricultural Statistics Service. Recent rain has
brought much needed relief to major crops. Pastures and forage crops
have also improved and greened up. Corn and soybean growth advanced
rapidly during the week with several corn fields reaching the silking
stage. Wheat harvest made good progress. Second cutting of hay crops
continued. "

Precipitation/Temperature Outlooks:
The six to ten day outlook, covering the period of July 8thto July 12th, indicates temperatures and precipitation will be near normal across central and southern Indiana.  Forecast confidence is below average. During this time period, normal precipitation is about eight tenths of an inch.
Further out in time the eight to fourteen day outlook, covering the period of July 10th to July 16th indicates below normal temperatures and above normal precipitation. Forecast confidence is average.  Normal precipitation for this period is about one inch.
Thirty and ninety day outlooks call for equal chances of below, above, or near normal values of temperatures and precipitation.
