The U.S. Drought Monitor week ending on October 30, 2018 was marked by several weather events. The first, Hurricane Willa, made landfall as a category 3 storm on Mexico’s Pacific Coast just after the cutoff for last week’s map (8:00 AM ET, Tuesday). The remnants of this storm brought heavy rain and thunderstorms to Texas, which had already been saturated with excess rain over the last several weeks, and to other states in the southern tier of the country. These rains brought improvements to areas impacted by drought, including the long-term drought areas of Arizona and New Mexico. Moisture from Willa helped fuel the season’s first nor’easter, which soaked the Northeast and brought snow to the higher elevations of New England over the weekend, helping to ameliorate drought and abnormal dryness across the regions. Storms also brought precipitation to the Pacific Northwest, the upper Midwest, and the Ohio Valley, bringing drought relief to these areas. Virtually no degradations occurred this week, except for an expansion of abnormal dryness across the Florida Panhandle..
The trend toward improvement continued across the High Plains this week as recent moisture helped to improve both short- and long-term deficits. Broad reductions were made in North Dakota as precipitation deficits were reduced, soil moisture was replenished, and ground and surface water conditions improved. Changes include the elimination of extreme drought and a reduction of severe and moderate drought. South Dakota saw 1-category improvements to the drought depiction east of the Missouri River due to reductions in precipitation deficits, increases in soil moisture, reduced evaporative demand and feedback from local experts. Since remaining deficits are at longer time scales, the drought designation was changed from SL to L to reflect this…
Heavy precipitation in the Pacific Northwest, with amounts of 5 to 10 inches, brought 1-category improvements to the moderate and severe drought areas in western Washington. The excess rainfall helped increase streamflow, replenish soil moisture, and recover precipitation deficits. Likewise, improvements were made in south-central Idaho this week, where above-normal precipitation over the last 30-days was enough to improve soil moisture and precipitation deficits. Drought conditions in Montana remained unchanged, though the short-term designation was removed from the easternmost drought area because moisture deficits are only apparent at longer time scales. Colorado saw improvements in response to recent moisture, which reduced short- and long-term precipitation deficits and helped surface and soil moisture recover. Changes were limited to the eastern half of the state, which saw the removal of extreme drought and reductions in severe and moderate drought. Farther south, rain and thunderstorms associated with the remnants of Hurricane Willa helped to chip away at the long-term deficits in the southwest. The Rio Grande Valley in New Mexico saw 1-category improvements to moderate, severe, and extreme drought areas as most indicators in these areas are beginning to show recovery. Locally heavy rain in south-central Arizona led to an improvement in moderate drought conditions…
The greatest chances for precipitation in the coming week are in the Pacific Northwest, Northern and Central Rockies, and across the eastern half of the continental U.S., particularly in a band stretching from east Texas to New England. In the West, this could impact drought-affected areas in western Washington and Oregon, northern Idaho, and parts of Colorado and New Mexico. Much of the rainfall in the eastern half of the country is expected to fall in areas that are currently drought free, with the exception of northeast New York and northern Vermont.
