#Drought news: No change in depiction for #Colorado

Click here to go to the US Drought Monitor website. Here’s an excerpt:


During the past 7-days, frequent frontal activity helped to ensure heavy rainfall (2 inches or greater) over portions of the Midwest, the Middle and Lower Mississippi Valley, the southern Plains, the Ohio and Tennessee Valleys, the Northeast and mid-Atlantic, and the Pacific Northwest. The Southern Atlantic Coast region also received areas of heavy rainfall due to the slow passage and subsequent meandering of Tropical Storm Julia. Drought remains entrenched over the southern Appalachians vicinity, parts of the Northeast/eastern Great Lakes region, the northern Plains, and much of the West…

Great Plains and northern Rockies

In western Montana, moderate precipitation (0.5-2.2 inches) led to small improvements in the drought depiction, including the reduction and/or removal of D2 in Granite, Ravalli, and Missoula Counties. However, increasing dryness across the rest of the state prompted the expansion of D0, D1, and D2 categories across most of the southern half of the state. Groundwater levels along the Rocky Mountain Front (especially Teton County) are a concern. In northeastern Oklahoma, persistent dryness, reduced pond levels, spotty rains which keep hitting (or missing) the same areas, dormant grass, 30-, 60-, and 90-day DNPs, CPC Soil Moisture, and the 30-day SPI warranted a modest increase in coverage of D0 and D1 in this part of the state. Recent precipitation in south-central Oklahoma resulted in the removal of a D1 patch. In Texas, localized adjustments were made to the map, though as a whole, the state remains in relatively good shape…

Southwest/Four Corners region

Beneficial precipitation in recent weeks and cooler temperatures are helping to moderate ET demand, prompting some improvement of D1 in north-central Utah (Duchesne and Carbon Counties), and trimming of D2 in Carbon County. The 30-day SPI has improved to the 0 to +1 range in this area. An impact line was introduced in Colorado to emphasize the short-term nature of the drought there, while the “SL” impact label (emphasizing both short- and long-term impacts) still fits for much of the surrounding area. This was based to a large degree on the objective “worst case” drought blends…

California and western Great Basin

Since this is the normally dry and warm time of the year when no real changes are expected to occur, there were no changes made on the map…

Looking Ahead

During the next 5 days (September 22-26), most dryness or drought areas east of the Mississippi River are not expected to receive significant rainfall. Beneficial rain is, however, forecast for some areas west of the Mississippi River, including the southern Plains (2-3 inches), and from the northern High Plains and northern Rockies southward across northern Utah (1.5 to locally as much as 6.0 inches). During the 6-10 day period, September 27-October 1, odds favor above-median precipitation across the south-central contiguous U.S., peninsular Florida, and the Upper Mississippi Valley/Dakotas region. Odds favor below-median precipitation for portions of the mid-Atlantic, Carolinas, northern Georgia, and eastern parts of Kentucky and Tennessee. Below-median precipitation is also favored for most areas west of the eastern slopes of the Rockies.
