USDA's Joint Ag Weather Facility says on the Plains, cool conditions prevail, along with widely scattered showers. "On the southern High Plains, weekend rainfall provided much-needed moisture for rangeland, pastures and winter grains, although neither coverage nor intensity was sufficient to provide widespread drought relief," USDA reports. In Amarillo, Texas, the April 6 rainfall of 0.40 inch exceeded the total (0.30 inch) during the preceding 8 weeks, from Feb. 9 to April 5, USDA elaborates.
In the West, USDA reports mostly dry weather accompanies a rapid warming trend. Today’s high temperatures will top 80°F throughout California’s Central Valley. "Any lingering precipitation is confined to the central Rockies, where a few snow showers are occurring," USDA continues.
In the Corn Belt, USDA says rain showers are mostly confined to areas from southern Missouri into the Ohio Valley. "Widespread cloudiness and near- to below-normal temperatures cover the remainder of the Midwest," USDA details.
In the South, USDA explains showers and locally severe thunderstorms stretch from the southern Mid-Atlantic states to the central Gulf Coast. "Most Southern fieldwork remains nearly at a standstill due to recent or ongoing rainfall, although cool, dry air is settling across the western Gulf Coast region," USDA details.
In its outlook, USDA says a storm system currently centered over the Mid-South will drift northeastward, reaching eastern Canada by mid-week. "Strong thunderstorms will remain a threat for the remainder of the day across the lower Southeast," USDA explains. Additional precipitation associated with the storm will locally exceed an inch from the Ohio Valley into the Atlantic Coast States, according to USDA. Amounts may approach 3 inches in the Southeast due to thunderstorm activity, USDA adds. In the storm’s wake, precipitation will be mostly light and confined to the northern U.S., USDA continues. "Meanwhile, a sudden warming trend in the West will quickly expand eastward, encompassing most of the nation by week’s end," USDA details. Mid-week temperatures could briefly reach 80°F as far north as the Dakotas, USA explains. In addition, temperatures will frequently approach 100°F in the Desert Southwest and occasionally exceed 90°F across portions of the southern High Plains, according to USDA.
