The storm, which produced 1- to 3-inch rainfall totals in many areas, resulted in a reduction in the coverage of abnormal dryness (D0) and moderate drought (D1) in the northern Mid-Atlantic region.
For example, there was a slight increase in coverage of moderate and severe drought (D1 and D2) in southern Florida, while D2 persisted in many areas along and near the Atlantic Coast in Georgia and South Carolina.
South A sharp line between no drought and moderate to exceptional drought (D1 to D4) continued to slice across Oklahoma and Texas.
On April 15, topsoil moisture was rated 72% very short in Oklahoma, along with 66% in Texas.
Midwest A major, late-season storm dumped heavy snow across much of the northern half of the region, sharply reducing the coverage of abnormal dryness (D0).
In Wisconsin, April 13-16 storm-total snowfall included 24.2 inches in Green Bay and 20.7 inches in Wausau.
In both locations, it was the biggest April storm (previously, 11.0 inches in Green Bay on April 4-5, 1977, and 12.1 inches in Wausau on April 15-16, 1993) and the second-highest event total on record.
High Plains Heavy snow also blanketed portions of the northern Plains, while dry, windy weather dominated drought-affected areas of the central Plains.
A more significant storm will traverse the West and produce heavy snow in the central Rockies before crossing the Plains on Friday.
Precipitation totals associated with the storm will be variable, but some drought-stricken areas of the central and southern Plains could receive as much as 0.5 to 2.0 inches of rain.
