#Drought news: Abnormal dryness (D0) reduced in NW #Colorado

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

The Central Great Plains, Middle Mississippi Valley, and Lower Ohio Valley

Looking at the area from Indiana westward through Nebraska and Kansas, beneficial light to moderate precipitation in the western half of Nebraska and adjacent Colorado, some of which fell as snow. This brought an end to the abnormal dryness in the southern Nebraska Panhandle and adjacent Colorado. Farther south and east, only light precipitation at best fell from central parts of Indiana, Illinois and Missouri westward through Kansas, primarily in eastern sections of the region. As a result, limited D0 and D1 expansion occurred in parts of Kansas, where very little precipitation fell. No changes seemed warranted farther east. Most of eastern Kansas and the southwestern quarter of Missouri received less than half of normal precipitation during the last 30 days, as did portions of central Indiana and Illinois. Precipitation deficits of at least 4 inches have accumulated in most of the same region since early August, with totals in much of central Missouri 6 to 8 inches below normal during this period…

The Rockies, Intermountain West, and Far West

Moderate to heavy precipitation fell on the Sierra Nevada, northwestern California, western sections of Washington and Oregon, northern sections of the Rockies and Intermountain West, scattered areas from western Colorado to central Arizona, and a few other isolated spots. Other locations received little, if any. The wet/snowy season is off to a rapid start in the Intermountain West and West Coast States. Snowpack is well above normal for this time of year in the Sierra Nevada and parts of Nevada where drought has seemed intractable, Reno Tahoe Airport recorded 4.2” of snow November 9-10 (including a daily record 2.4” on the 9th), and over a foot blanketed some areas northeast of the city. But given the long-term nature of the drought in much of the Far West, only scattered areas of improvement were noted. D1 in south-central Idaho improved to D0, areas of D3 shrank a little in western Idaho and west-central Montana, severe drought eased to moderate levels in central Washington, abnormal dryness was eliminated in northwestern Colorado, coverage of D1 and D2 declined in southeastern Arizona, and a few other isolated areas saw improvement. Areas where drought was more entrenched will need abundant precipitation to continue much farther into the wet season before any notable improvement could evolve…

The Southeastern Great Plains, Lower Mississippi Valley, and Adjacent Southeast

Moderate to heavy precipitation fell on most of this region. Most areas from the Mississippi/Ohio Confluence southward through the Lower Mississippi Valley, southeastern Oklahoma, and eastern Texas reported at least an inch of precipitation, with 2 to locally over 5 inches measured in a swath from southern Missouri into northwestern Arkansas, plus an area farther south extending from southeast Oklahoma and northeastern Texas eastward through southern Arkansas, much of Louisiana, and some parts of Mississippi outside the areas of abnormal dryness and moderate drought. Large areas of improvement were introduced in the wetter areas, and most other areas were unchanged; however, D0 was expanded into parts of eastern Arkansas, southwestern Tennessee, and northwestern Mississippi that missed most of the precipitation. The eastern half of this area received only 50% to 75% of normal rainfall in the last 30 days, and deficits of 4 to locally 6 inches have accumulated since early September…

Looking Ahead

During November 12-16, the heaviest precipitation should fall on windward slopes in western Washington and northern Idaho. Peak values of 12 to nearly 18 inches are anticipated in the northwesternmost reaches of Washington while totals may top 6 inches in northernmost Idaho. Substantial totals are also expected in western Oregon and far northwestern California, with amounts topping out in the 2 to 4 inch range along the Oregon Coast. Relatively heavy precipitation is also anticipated across the northern half of the Great Lakes, with 2 to 3 inches forecast in northwestern Wisconsin and adjacent areas. Meanwhile, moderate precipitation (with amounts above 2 inches only in a few isolated locations) is expected across the northern half of New England and New York, far southern Florida, the southeastern Great Plains and western Lower Mississippi Valley, and parts of the northern Sierra Nevada and southern Cascades. Temperatures should average well above normal (5 to 10 degrees) in the northern half of the Plains and much of the Great Lakes Region. In contrast, temperatures should average around 3 degrees below normal in the Great Basin and central Intermountain West.

For the ensuing 5 days (November 17-21), the odds at least slightly favor wetter than normal conditions nationwide, except in a small part of the northern Plains and in a swath across the Big Bend of Texas, southern sections of Arizona and New Mexico, and central and southern California. All of Alaska has enhanced chances for above normal precipitation as well. The best chances for wetness are in the southern half of the Mississippi Valley. We should see warmer than normal temperatures on average in the central and eastern parts of the country and cooler than typical conditions from the Rockies westward.
