| January marked the second consecutive wet month averaged across the Pacific Northwest, contributing to some improvement in drought conditions in the region, but long-term deficits remained. The month averaged much drier than normal for the West and Southwest regions. |
 |
 |
| Moderate to extreme drought covered 75% of the western U.S. (Rocky Mountains to west coast) at the end of January. This makes the current drought the most extensive for this region since the drought of the 1930s. Of particular concern was the below-average mountain snowpack, as seen in snow course measurements and SNOTEL station snow water equivalent observations, and below-average reservoirs. The winter mountain snowpack is the source of spring meltwater which fills western reservoirs and is used for irrigation during the spring and summer growing seasons. |
A detailed review of drought conditions is available for several western states and regions.
Central U.S. Drought
| January was unusually dry across much of the central U.S., with the Great Lakes (East North Central region) and southern Plains (South region) experiencing the third driest January in the 109-year record, and the Ohio Valley (Central region) having the fifth driest January on record. This month marked the third consecutive dry month for the East North Central region, which experienced the driest December-January and November-January on record. |

| The dryness has significantly depleted soil moisture from the central Plains to the Great Lakes. This is evident in modeled soil moisture departures as computed by the NOAA Climate Prediction Center and the Midwest Regional Climate Center at both the top soil layers and deeper layers. The drought has caused significant crop losses in the states of the West North Central region and near-record low levels for the Mississippi River at St. Louis. |

Eastern U.S. Drought
|
The dryness of January marked the end of a four-month wet spell for much of the east coast. Most areas here had recovered from the drought by the end of December, with only long-term hydrologic impacts (for example, low well levels) remaining. But January's dryness increased the moisture stress in many areas, with the Southeast region having the fourth driest January, regionwide, in the 109-year record. An exception is Maine, where four of the last six months have averaged drier than normal, statewide. Maine had the third driest January and fourth driest August-January in the 109-year record.
