Around 40% of U.S. Now Drought-Free

The storm system that brought beneficial moisture to parts of the central Plains and western Corn Belt last week slowly trekked eastward. It dropped widespread moderate to heavy precipitation (more than 2 inches) on the remainder of the Corn Belt and Great Lakes region, and on the Delta, Tennessee Valley, southern Appalachians, and South. Heavy snows also blanketed portions of the northern Plains.

Later in the period, a new storm system produced light to moderate precipitation in the Pacific Northwest, northern and central Rockies, and northern Plains. Unfortunately, little or no precipitation was observed in California and the Southwest, Intermountain West, southern and central High Plains, and portions of the southern and middle Atlantic Coast States.

Temperatures averaged above-normal in the Southwest, Southeast, and mid-Atlantic, where highs topped 90 degrees F in the latter region early in the period. In contrast, subnormal readings prevailed across the Northwest, Rockies, Plains, upper Midwest, Great Lakes region, northern New England, and Alaska. It was up to 20 degrees F below normal in the Black Hills of South Dakota and in interior Alaska.


The next 5 days (April 18-22) are expected to be very wet in the middle of the country, with a swath of 3 inches of precipitation expected from Oklahoma northeastward into Michigan. Much of the eastern half of the nation should receive decent precipitation, with parts of the pacific Northwest, northern Rockies, and central Rockies and Plains expecting moderate totals. Unfortunately, dry weather is forecast for most of the Southwest and extreme southern Plains.

Subnormal 5-day average temperatures are predicted for the middle of the U.S., especially the North-Central States. Near to somewhat below-normal readings are expected elsewhere, except in California and southern Florida where temperatures should average above-normal.

For the ensuing 5 days (April 23-27), the odds favor wet weather persisting in the eastern half of the Nation and in southeastern Alaska, with drier than usual conditions in the West, Rockies, High Plains, and western Alaska. Above-normal temperatures are favored in the western third of the U.S. and northern New England, with strong chances for subnormal readings from the Plains eastward to the Appalachians.
