This Week’s Drought Summary

This U.S. Drought Monitor week saw some modest improvements in drought conditions across portions of the Southwest, southern Great Plains, South, lower Midwest, and portions of the Northeast. Drought-related conditions deteriorated in southern California, the southern Great Basin, Texas, Minnesota, and parts of New England. In California, storm activity during the weekend delivered beneficial rain and snow to areas of central and northern California; however, the southern part of the state remained dry. Since January 1, areas of California—including portions of the eastern Sierra and Sacramento Valley—have received less than 25% of normal precipitation. The impact of both short- and long-term dryness in parts of California has been affecting the cattle ranching industry with numerous drought impact reports describing severe impacts to pasture and rangeland conditions as well as reports of ranchers having to sell livestock. Fortunately, another round of storms is expected to impact northern California this week bringing valley rains and mountain snows to the region. In the southern Great Basin, record dryness during the past 6-month period led to expansion of areas of Exceptional Drought (D4) in the eastern Sierra Nevada and southern Nevada. In the Southwest, both Arizona and New Mexico received light rains across parts of the lower deserts as well as some mountain snowfall in northern Arizona and northern New Mexico, providing a much-needed boost to soil moisture levels. Elsewhere, above-normal precipitation during the past 30-to-60-day period and snowfall this week in northern portions of the Texas Panhandle and Oklahoma Panhandle, led to removal of areas of drought. Further to the south in the Hill Country and South Texas Plains, drought intensified in response to persistent warm and dry conditions as well as mounting precipitation deficits ranging from 2-to-8+ inches during the past 90-day period. Conversely, areas along the coastal plains of northeastern Texas received 1-to-2+ inch accumulations during the past week leading to widespread improvements on the map. In the Midwest, wetter-than-normal conditions during the past 30-to-60-day period led to minor improvements on the map in central Illinois and northern Indiana. Likewise, portions of western New York saw improvement on the map in response to recent storm activity…

High Plains

On this week’s map, areas of the region—including southwestern Kansas and northeastern Wyoming—saw modest improvements including reduction in areas of Severe Drought (D2) in Wyoming and areas of Moderate Drought (D1) in southwestern Kansas where recent snowfalls have helped to improve local conditions. Average temperatures for the week were near to slightly above normal across most of the region with eastern portions of the region observing the greatest positive temperature anomalies ranging from 3-to-12 deg F above normal. According to the NOAA NOHRSC, the Upper Midwest Region was only 16.4% covered in snow (a reduction from 30.3% last month) with an average depth of 0.2 inches and a maximum depth of 30.5 inches. Field reports from the USDA NASS North Dakota Crop Progress and Condition Report (Nov. 30) yielded winter wheat conditions rated as 4% very poor, 5% poor, 50% fair, 39% good, and 2% excellent…


During the past week, areas of the West received much needed rain and snow over the weekend with mountain snow observed in the Cascades, Sierra Nevada, ranges of central/eastern Nevada, the Uinta Mountains, and across areas of the Rockies from Montana to New Mexico. Snowfall accumulations ranged from 6-to-24+ inches in the higher elevations. In the California mountains, the current statewide soil water equivalent (SWE) for the date (Dec. 14) is 47% of normal—up 11% since last week. The current regional breakdown (percentage of normal SWE) is as follows: Northern Sierra/Trinity–46%, Central Sierra–53%, and Southern Sierra–29%. In other areas of the West, the drainage basins (6-Digit HUCs) across the Four Corners states continued to observe well below-normal SWE except for the Rio Grande Headwaters (115% of normal) and the Upper Arkansas (103% of normal) basins of Colorado. In the Pacific Northwest and northern Rockies, basins across the Cascades of Oregon/Washington as well as central/eastern Montana are near normal to above normal. On the map, areas of Severe Drought (D2) and Extreme Drought (D3) expanded in southern California where precipitation during the past 90-day period has generally been <25% of normal. These areas largely have missed recent storm events that have impacted central and northern portions of the state. In southern Nevada, areas of Exceptional Drought (D4) expanded in Clark County where McCarran International Airport (through Dec. 1) logged its driest 6-month period (June 1 to November 30) on record with only a trace of precipitation observed for the period. In Arizona, areas of Extreme Drought (D3) expanded in southwestern Arizona where Parker, Arizona along the lower Colorado River has observed no precipitation since June 1—making it the driest 6-month (June 1 to November 30) on record. Elsewhere in the state, some minor improvements were made in central Arizona and northeastern Arizona on the Navajo Nation where precipitation during the past week brought some minor improvements in soil moisture. In northern New Mexico, some minor improvements were made on the map in the Sangre de Cristo Range near Taos where soil moisture levels improved (according to NASA SPoRT) and snowfall during the past week bumped a few SNOTEL stations (Gallegos Peak, Tolby) above normal levels for the date. In southeastern Idaho, areas of Moderate Drought (D1) were reduced in response to several SNOTEL sites (Prairie, Camas Creek Divide) reporting above-normal SWE…


On this week’s map, areas of drought intensified and expanded in the Hill Country and South Texas Plains where warm and dry conditions continued this week. In these areas, 90-day precipitation deficits ranged from 2-to-8 inches, and current soil moisture levels were below normal according to the NASA SPoRT soil moisture monitoring products. According to Water Data for Texas (Dec. 16), monitored water supply reservoirs are currently 79.9% full—with reservoirs in the eastern half of the state ~80–90% full while reservoirs in the western half of the state were generally <40% full. In the far northern portions of the Texas Panhandle and Oklahoma Panhandle, conditions improved on the map in response to short-term precipitation including snowfall observed during the past week with accumulations ranging from 1-to-8+, according to NOAA NOHRSC. In eastern portions of Texas, northwestern Louisiana, and southeastern Oklahoma, precipitation during the past week (1-to-3 inches) led to improvements in areas of Moderate Drought (D1). Average temperatures for the week were below normal (1-to-4 deg F) in the northern Texas Panhandle, Oklahoma Panhandle, and central Oklahoma while other areas in the region were 2-to-10+ deg F above normal…

Looking Ahead

The NWS WPC 7-Day Quantitative Precipitation Forecast (QPF) calls for light-to-moderate liquid accumulations ranging from 1 to 2+ inches across portions of the South with the heaviest totals expected along the Gulf Coast of Louisiana and the Florida Panhandle. Likewise, similar accumulations are expected in the Mid-Atlantic and across southeastern portions of New England where a major winter storm is expected to impact the region starting on Wednesday with a wintry mix of rain, freezing rain, and snow. Areas from Pennsylvania to Massachusetts are expected to receive significant snowfall accumulations ranging from 6 to 20+ inches with New York City and Boston potentially receiving more than a foot of snow. Across much of the Midwest, the Plains, Texas, the Southwest, and southern portions of California and the Great Basin, dry condition are forecasted. Elsewhere in the West, a series of storms is expected to impact an area from Washington state through northern California and eastward through the northern Great Basin and central/northern Rockies. Coastal areas are expecting heavy rainfall accumulations while further inland snowfall accumulations in the higher elevations of the Cascades and northern Rockies of Idaho and northwestern Montana could see 1-to-2 feet of snow. The CPC 6–10-day Outlook calls for a moderate probability of above-normal precipitation across most of the eastern tier of the conterminous U.S., the Upper Midwest, and across much of Alaska where probabilities are higher. Elsewhere, the outlooks call for a low-to-moderate probability of below-normal precipitation across much of the conterminous U.S.—including much of the Midwest and Plains states, the Four Corners states, and California. In terms of temperature, there is a moderate-to-high probability of above-normal temperatures across nearly the entire conterminous U.S. except for the Southeast where normal temperatures are expected…

The Energy 202: Biden’s choice of ex-#Michigan governor as energy secretary points to focus on #electriccars — The #Washington Post

Leaf Byers Canyon August 21, 2017.

From The Washington Post (Dino Grandoni):

President-elect Joe Biden’s choice of Jennifer Granholm to be his energy secretary is a sign the president-elect’s team will try to spur automakers to sell cars that need little to no gasoline.

The relationship that Granholm, the former two-term governor of Michigan, has with Detroit automakers may prove crucial to the incoming administration’s effort to cut climate-warming emissions spewing from the millions of cars and trucks on American roads.

Biden intends to nominate Granholm to run the sprawling department also responsible for overseeing the nuclear weapons arsenal and managing radioactive waste, Will Englund, Juliet Eilperin and I report.

Cleaning up the transportation sector, now the largest source of greenhouse gas pollution in the United States, will be critical to meeting Biden’s lofty goal of net-zero emissions by the middle of the century.

Biden, the son of a car salesman, pitched no- and low-emissions vehicles not only as a way to combat climate change, but also to create domestic manufacturing jobs. To preserve Michigan’s industrial base undercut by foreign competition, Granholm has also become a vocal proponent of building electric vehicles at home…

The Transportation Department – which under Biden will be run by former South Bend. Ind., mayor Pete Buttigieg, our colleagues Michael Laris, Ian Duncan and Seung Min Kim also reported Tuesday – has “transportation” in its name.

But it is the Energy Department that is the main funder of research into the battery technology responsible for a potential transition to electric vehicles…

During the campaign, Biden promised to install 500,000 electric vehicle charging stations by 2030, provide bigger tax breaks to those who purchase electric vehicles and to tighten fuel-efficiency standards on new cars and trucks…

Today, electric vehicles make up less than 2 percent of new cars and SUVs sold each year domestically. But GM, Ford and other automakers have told investors they plan to build out their fleets of electric vehicles in coming years.
