However, none are now classified in extreme drought and only one is in severe drought. All climate divisions have undergone PDSI moisture increases since October 22. Every climate division is experiencing near long-term dry conditions, according to the SPI. Keetch-Byram Drought Fire Index3 MESONET STATION CLIMATE DIVISION CURRENT VALUE 11/28/2011 Stations currently at or above 600 (November 28) = 4 Stations above 600 on October 24 = 25 Hooker Panhandle 731 Beaver Panhandle 670 Goodwell Panhandle 627 1 The Palmer Drought Severity Index, the first comprehensive drought index developed in the United States, is calculated based on precipitation, temperature, and soil moisture. Though widely used by government agencies and states to trigger drought relief programs, the PDSI may underestimate or overestimate the severity of ongoing dry periods. 2 The Standardized Precipitation Index, more sensitive than the PDSI, provides a comparison of precipitation over a specified period with precipitation totals from that same period for all years included in the historical record. The 3-month SPI provides a seasonal estimation of precipitation while the 6-month SPI can be very effective in showing precipitation over distinct seasons. 3 The Keetch-Byram Drought Index measures the state of near-surface soil moisture (within the uppermost eight inches of soil) as well as the amount of fuel available for fires. KBDI values of 600 and above are often associated with more severe drought and increased wildfire occurrence. Water Resources Bulletin, 12/1/2011 – page 3 WEATHER/DROUGHT FORECAST 8- to 14-Day Outlook December 6-12, 2011 Temperature Precipitation Regional Drought Summary & Outlook November 29—The latest U.S. Drought Monitor reports that another round of light to moderate precipitation fell on most of the southern and central Plains, continuing a recent pattern of near to above normal precipitation. This was good news after Oklahoma recorded the second driest October-September period (12-months) on record (since 1895) in 2010-2011. Along the Kansas/Oklahoma border, 0.5 to 1.5 inches of precipitation occurred while 0.3 to one inch was measured in the rest of Oklahoma and central and eastern Kansas. Also due to lower temperatures and declining evapotranspiration rates, some 1-category improvements were made in eastern Oklahoma, and along the Kansas-Oklahoma border. Runoff from recent rains has filled Lakes Hugo, Broken Bow, and Wister. USGS stream flows bordering Arkansas are averaging 80 percent of normal or better. In contrast, lake levels remained essentially unchanged from last week elsewhere. Major soil moisture issues below the topsoil remained in west central and northwestern areas. Lakes Great Salt Plains, Fort Supply, Canton, Lugert-Altus, Tom Steed, and Skiatook are down 40-80 percent with almost no recharge in the past month. Therefore, D3 and D4 remained in western and central Oklahoma. According to the latest Drought Outlook (December 1), La Niña conditions developed during the fall season in the northern hemisphere for the second year in a row. During the previous two weeks, widespread rainfall further eased lingering drought conditions across the lower Mississippi Valley and southeastern Plains in a continuation of a wet autumn pattern. Short-term forecasts indicate new rounds of heavy rainfall in early December, which will likely bring additional improvement from southeastern Kansas through northern Louisiana. An early December winter storm might also bring some early mountain snowfall to the Southwest, though overall below median precipitation is expected during the winter season. However, ongoing drought conditions elsewhere across the southern tier of U.S. states are expected to persist or worsen. Water Resources Bulletin, 12/1/2011 – page 4 CROP REPORT November 28, 2011 – A significant rainfall event Monday brought a good soaking rain, especially in southeast Oklahoma. Recent rains were reflected in improvements to the November 22 Drought Monitor although 63 percent of the state is still in a severe to exceptional drought, down from 85 percent the week before. The additional moisture helped small grain conditions and improved the availability of wheat grazing this fall. However, recent rains could not mitigate all the negative effects of the drought, as the lack of hay and pasture were still problems for livestock producers. Topsoil moisture conditions improved and are now rated mostly adequate. Subsoil moisture conditions also improved, though 47 percent are still rated very short, down from 56 percent the week prior. There were 4.6 days suitable for field work due to the multiple showers throughout the week. Canola and small grain conditions continued to be rated mostly good to fair. Wheat grazing prospects improved, with additional moisture still required to make it through the winter months. Wheat emerged reached 97 percent complete. Seedbed preparation for oat ground was 85 percent complete, oat planting reached 64 percent complete, and 63 percent had emerged, even with the five-year average. The fall harvest began to wind down and was more than three-quarters complete for all row crops. The sorghum harvest was 85 percent complete, slightly behind the five-year average. Soybeans harvested reached 83 percent complete by Sunday, 11 points behind normal. Peanuts combined reached 95 percent complete by Sunday. The cotton harvest was 77 percent complete by week’s end, eight points ahead of the five-year average. Recent rainfall events were too late in the season to benefit hay production, as very little hay was cut last week. Hay supplies for the season were rated below average for 87 percent of the state. Third cuttings of alfalfa were 76 percent complete, and 23 percent of the state had completed a fourth cutting. A second cutting of other hay was 61 percent complete by Sunday, 33 points behind normal. Half of the pasture and range in the state was rated in very poor condition. The availability of grass continued to be of great concern to livestock producers as continued growth of cool season grasses is limited. Livestock conditions continued to be rated mostly good to fair, unchanged from last week. Many livestock ponds were replenished with the rains last week, especially in the southeast. However, some areas have still not received large enough rain amounts to produce the runoff needed for ponds.
