This Week's Drought Summary (1/28)

The heaviest precipitation this week fell on a swath across southwestern Kentucky and immediately adjacent locales (3.0 to 4.5 inches), and the higher elevations of Arizona (3.5 to locally over 6 inches). Moderate to heavy amounts of 1.5 to locally 4.0 inches pelted the rest of Kentucky, southern Missouri, northeastern Arkansas, just north of the central Gulf Coast, and patchy areas across southern Virginia and the interior Southeast. Similar amounts dotted southern California and the higher elevations of the southern Sierra Nevada and the Four Corners region, especially across Arizona. Light to moderate precipitation extended across the remainder of the interior Southeast, from central Texas northward through the upper Midwest, across some lower elevations of the Four Corners region, in parts of the southern Great Basin, through most of the Sierra Nevada, and along much of the immediate West Coast. Much of the precipitation fell as heavy snow late in the period from Kansas and Nebraska to the lower Great Lakes. Amounts topped one foot at scattered spots across southwestern Iowa and southeastern Nebraska, with Omaha, NE reporting just under a foot. Small areas of moderate precipitation were observed in some areas to the lee of Lakes Erie and Ontario, but otherwise, the driest areas this week – reporting little or no precipitation – stretched along the northern tier of states from the Cascades through New England, most of the Intermountain West, the High Plains, southern Texas, Florida, the southern Atlantic Coast, the northern Ohio Valley, and the middle Atlantic States. No large, broad-scale changes were appropriate as a result, but numerous smaller-scale adjustments were introduced.
