To the east, light to moderate precipitation fell on the northern and central Rockies, north-central Plains, the western Corn Belt, and most locations in the eastern third of the Nation.
Southeast Most areas of the Southeast region reported light to moderate (0.5-2 inches) precipitation, including moderate to heavy totals in north-central Florida (3-8 inches), eastern Carolinas (1.5-2.5 inches), and western Alabama (1.5-3 inches).
Plus with all short-term indices (SPIs, soil moisture models, CPC blends, USGS stream flows, EDDI) showing drought conditions, D0 and D1 was expanded northward into north-central Georgia and northern South Carolina to reflect this.
In southern Louisiana, light showers (0.5-1.5 inches) fell on the D0 area, but the heaviest rains fell north and south (offshore), thus no changes were made.
In Wisconsin, another round of light snow was enough to remove some D0 in central sections, and D0 was returned to extreme southeastern portions near Lake Michigan where enough short-term indicators were at D0 or drier.
High Plains Another week of light precipitation (snow) and subnormal temperatures enveloped the northern Plains, with some heavier amounts (0.5-1 inch) falling on northern and eastern South Dakota and the Black Hills.
With the continued train of spring storms providing badly-needed moisture to California, additional improvements were made to areas with the greatest weekly totals (3-8 inches) that have also neared their normal WYTD precipitation.
April 10 snow water equivalents (SWE), however, remained below normal, with northern (36%), central (51%), and southern (39%) Sierras seeing some snow melt from lower elevation rains.
D3 now covered southeastern Utah, southwest Colorado, and central New Mexico as another dry and warm week dropped WYTD basin average precipitation to 50, 43, and 19-27% of normal, respectively, while the mountain snows have completely melted in eastern Arizona and most of New Mexico (0% SWE).
In Alaska, drier weather and mostly seasonable temperatures (except in northern locations) prevailed after a wet and snowy March in southwestern, northern, and interior sections.
