Agricultural Weather and Drought Update – 8/14/12

U.S. Soybean Coinditions, August 12, 2012. Data obtailed from preliminary National Agricultural Statistics Service (NASS) weekly crop progress and condition tables.

U.S. Soybean Conditions, August 12, 2012. Data obtained from preliminary National Agricultural Statistics Service (NASS) weekly crop progress and condition tables.

Cooler weather and recent rain showers have largely stabilized crop conditions in the Midwest.  Rainfall has been heaviest in the eastern Corn Belt, including Michigan and Ohio, although nearly all of the Midwest has received some precipitation.  Still, U.S. corn and soybean conditions remain at levels unseen since the Drought of 1988, according to USDA/NASS.  During the week ending August 12, corn rated very poor to poor rose slightly to 51%, just two percentage points shy of the August 1988 peak.  Soybeans rated very poor to poor reached a record-high 39% last week, but improved one percentage point during the week ending August 12.

This year’s U.S. corn crop is developing so rapidly that August rainfall will provide only limited drought relief.  By August 12, nearly half (42%) of the corn had dented, while 10% was fully mature.  Five-year averages for those two categories are 16 and 3%, respectively.  In contrast, soybeans seem to be benefiting from the turn toward cooler, wetter weather.  In Ohio, for example, the portion of the soybean crop rated very poor to poor fell from 42 to 34% during the week ending August 12.

Typically, rangeland and pastures are slow to recover from a devastating drought.  Complete recovery often requires not only the change of seasons, but also many soaking rainfall events.  Currently, the amount of U.S. rangeland and pastures rated in very poor to poor condition remains steady at 59%.  Nearly all of the rangeland and pastures are rated very poor to poor in Missouri (98%), Illinois (94%), Nebraska (92%), and Kansas (90%).  At least half of the rangeland and pastures are rated very poor to poor in 22 of the 48 contiguous United States.

Weather Update and Outlook:  Currently, a cold front is traversing the eastern Corn Belt.  A second cold front will arrive in the upper Midwest on August 15 and reach the South and East by August 17.  Both fronts combined will produce as much as 1 to 2 inches of rain, with locally higher amounts, mainly across the South, East, and lower Midwest.  Somewhat lighter amounts of rain can be expected across the northern and central Plains and the upper Midwest.  In the wake of the second cold front, unusually cool air will blanket the Plains and the Midwest.  In fact, an extended period of near- to below-normal temperatures can be expected east of the Rockies starting later this week and extending at least into next week.

The latest U.S. Drought Monitor, valid August 7, indicates that the percentage of corn and soybeans in drought remains relatively stable.  However, corn and soybeans in the most two serious drought categories (D3 to D4, or extreme to exceptional drought) continue to rise sharply.  Approximately 87% of the U.S. corn is within an area experiencing drought, down from a peak of 89% on July 24.  Similarly, 85% of the U.S. soybeans are in a drought area, down from a high of 88% on July 24.  During the three-week period ending August 7, corn in extreme to exceptional drought nearly quadrupled, from 14 to 53%, while soybeans in the two worst drought categories (D3 or D4) more than tripled from 16 to 50%.

During the week of July 29 – August 4, scattered showers and slightly cooler conditions provided some relief to drought-stressed summer crops—primarily soybeans—in the Corn Belt.  Weekly rainfall totaled an inch or more in numerous Midwestern locations, with at least 2 inches reported in parts of the middle Mississippi and lower Ohio Valleys.  Meanwhile in the Southeast, where 2- to 4-inch weekly totals were common, pastures and immature summer crops continued to benefit from widespread showers.  Farther west, however, extreme heat shifted to the southern Plains.  In fact, weekly temperatures averaged at least 10°F above normal—and highs topped 110°F—in an area centered on Oklahoma, where recent wildfires charred thousands of acres and destroyed dozens of homes.

Historically hot, dry conditions covered many of the nation’s key agricultural regions during July.  Preliminary data provided by the National Weather Service indicated that July rainfall totaled less than 50 percent of normal in a broad area stretching from the central and southern Plains into the Mid-South and Midwest.  No measurable rain fell during July in several locations.  Meanwhile, monthly temperatures generally ranged from 4 to 8°F above normal across the northern and central Plains and the Midwest.  It was the hottest July on record in cities such as Rockford, Illinois; Denver, Colorado; and La Crosse, Wisconsin, breaking all-time records set in 1921, 1934, and 1936, respectively.

Based on weather developments last week (July 22-28), U.S. corn and soybean conditions further declined in today’s USDA/NASS crop condition report.  The most significant crop deterioration occurred across the southern and western Corn Belt, where little or no rainfall accompanied temperatures that averaged 5 to 10°F above normal.  Multiple days of triple-digit (100°F) heat were noted last week in parts of Indiana, Illinois, Iowa, Missouri, Arkansas, and on the Great Plains from South Dakota to Texas.  In contrast, there was enough rain (locally 1 to 2 inches or more) across the northern Corn Belt, mainly from the Dakotas to Michigan and Ohio, to help stabilize crop conditions in some fields.  Parts of central and eastern Iowa also received highly beneficial rainfall in excess of an inch.

U.S. soybeans, rated 37% very poor to poor on July 29, 2012, have matched lowest conditions observed during the Drought of 1988.  That year, soybeans rated very poor to poor peaked at 37% on July 10, with a secondary peak of 35% on August 21.  Nearly half (48%) of the U.S. corn was rated very poor to poor on July 29, 2012.  In 1988, corn rated very poor to poor peaked at 53% on August 21.

Weather Outlook:  During the next five days, no appreciable drought relief can be expected across the hardest-hit drought areas of the Plains, Mid-South, or Midwest, although rainfall in isolated locations may exceed an inch.  Significant rainfall (1 to 3 inches, with locally higher amounts) will be confined to the Southwest and the Southeast.  The northern Corn Belt will continue to experience scattered showers and a reprieve from hot weather, but excessively hot conditions will prevail for the remainder of the week across the central and southern Plains, the Mid-South, and parts of the southern Corn Belt.  In some of the hottest areas across the south-central U.S., high temperatures will continue to approach 110°F.  Late in the week, cooler air will arrive across the northern Plains.

During the week ending July 24, 2012, the portion of the contiguous United States in drought inched upward to 64%, according to the U.S. Drought Monitor.  The Drought of 2012 continues to hit some of the nation’s most important agricultural regions especially hard, with more than seven-eighths of the nation’s corn (89%) and soybeans (88%) considered to be within an area experiencing drought.  In addition, more than one-third of both crops, 37% of the corn and 35% of the soybeans, are currently experiencing the two worst categories of drought – extreme to exceptional – designated by D3 and D4, respectively, on the Drought Monitor.
