Report – Drought Spreading into the Midwest

August 29, 2013 by   - () Leave a Comment

Past Week: Several cold fronts stalled across the Southeast during the past week, bringing slightly cooler temperatures and occasional precipitation to parts of the area. Moisture from what was briefly Tropical Storm Ivo off the coast of Baja California surged into the Southwest, resulting in moderate rains (0.5 – 1.5 inches, locally heavier) over a significant portion of the region. In the central part of the nation, above-normal temperatures combined with rapidly worsening drought, resulting in widespread deterioration of conditions especially across the Midwest.

Looking Ahead: During the Aug. 29-Sept. 2 time period, 1.0-2.5 inches of rain is expected from western North Dakota eastward across central Minnesota, continuing southeastward across much of Wisconsin and lower Michigan. Between 1.0-1.5 inches of rain is predicted to fall across much of Arizona. Temperatures across the Midwest are forecast to be about 8-12 degrees above normal for the first half of this period, followed by a brief respite, with temperatures near seasonal values.

For the ensuing 5 days (Sept. 3-7), near to below-median rainfall is favored across most of the central third of the country. Above-median rainfall is favored across the Four Corners region, most of the Rockies and Northwest, and the northern High Plains. Near to above-normal temperatures are predicted for all but northeastern portions of the country.
