Dryness Continues for Most of the Country


Dryness continues over most of the country with only isolated areas of above-normal precipitation for this week. The “snow drought” over much of the mountainous western United States is catching more attention, but there is time to make up the poor start to the current water year. Portions of California and coastal Washington did have good precipitation for the week, along with areas of southern Louisiana, east Texas, and southern Mississippi. A significant winter storm brought precipitation to many areas along the east coast from Florida to Maine, but this did not reach too far inland. Over the last 60 days, extensive areas of the country have recorded below 25 percent of normal precipitation, from the Southwest into the central Plains and Midwest as well as in the Southeast and into the Mid-Atlantic. Cold air has also dominated much of the Midwest and eastern United States, with departures from normal temperatures in the Mid-Atlantic 15-20 degrees below normal.

Southeast

Precipitation was recorded over much of central Florida and north along the Atlantic Coast into Maryland and Delaware. Most areas inland did not record any precipitation for the week, which continued the dry conditions that have been developing over the last 2-3 months. The rain along the coast did allow for some improvement to abnormally dry conditions in North Carolina, South Carolina and Georgia, with moderate drought improving along the coastal region of Georgia. Elsewhere, dryness continued and conditions deteriorated. Abnormally dry conditions were introduced into much of eastern Tennessee and western North Carolina. Abnormally dry conditions were introduced into northwest and central Georgia as moderate drought conditions expanded over the western portions of the state. Severe drought was introduced this week in the ACF Basin and included portions of southwest Georgia, southeast Alabama and the panhandle of Florida. In Alabama, abnormally dry and moderate drought conditions expanded to include more of the central portion of the state. Mississippi had an expansion of moderate and severe drought conditions in the central portion of the state.

Midwest

Precipitation was widespread over much of Missouri and into the Ohio River Basin, and with the cold temperatures, much of this was in the form of snow. With the cold weather dominating the region and soils freezing up, drought issues move slow this time of year. No changes were made this week to the region as the impact of the precipitation in the region will be slow to materialize. There are some dry pockets in both Wisconsin and Michigan that are not labeled as abnormally dry yet; these will be monitored in the coming weeks.

High Plains

A dry week for the region, but also a very cold week, with most of the eastern portions of the region recording temperatures 5-10 degrees below normal. Dryness over the last 3 months has been a concern, even during the fall and winter months. Moderate drought conditions were expanded over all of eastern Colorado, western Kansas and more of central Kansas. Severe drought was also expanded over southwest Kansas while a new area of extreme drought was introduced along the Oklahoma border where less than 10 percent of normal precipitation has been recorded over the last 90 days.

South

At the end of the current United States Drought Monitor period, the area from east Texas into southern Louisiana and southwest Mississippi recorded 1-2 inches of precipitation. A few areas that were abnormally dry did warrant improvements, but most areas welcomed the precipitation. In Arkansas, abnormally dry and moderate drought conditions were expanded in the central portion of the state while no changes were made in Louisiana. The dryness over the Texas and Oklahoma panhandle regions continued with an expansion of moderate and severe drought conditions this week and an introduction of extreme drought in Oklahoma. As of January 9, some areas of the Oklahoma and Texas panhandles and southern Kansas have gone 95-100 straight days with less than 0.10” of precipitation, with several locations reporting no precipitation at all during that time. Extreme drought also expanded in northern Texas. Moderate drought and abnormally dry conditions were also expanded in portions of central, southern, and west Texas.

Looking Ahead

Over the next 5-7 days, precipitation is widespread over much of the contiguous United States, with all but areas of the Southwest expecting to record some precipitation. The Pacific Northwest and northern Rocky Mountains are anticipated to have significant precipitation with liquid amounts of 3-4 inches along the coasts of northern California, Oregon, and Washington as well as over much of northern Idaho and western Montana. Significant precipitation is also anticipated over the Ohio River Valley and into the Mid-Atlantic, where 1.50-2.50 inches of liquid precipitation is forecast over widespread areas. Cooler than normal temperatures are anticipated over most areas east of the continental divide with departures of up to 15 degrees below normal while the western areas are anticipated to be warmer than normal with departures of 5-10 degrees above normal. The 6-10 day outlooks show that the trend of warmer over the West and cooler over the East will likely continue. Temperatures have the greatest chance of being below normal over the Mid-Atlantic into the Southeast and above normal over the Southwest. Precipitation chances are projected to be greatest over the Great Basin and Pacific Northwest as well along the Mississippi River Valley. Drier than normal conditions are anticipated to mainly be over the areas of west Texas and southern New Mexico as well as along the coastal regions of the Southeast, with higher than normal chances of dry conditions along much of the east coast.
