USDA's Joint Ag Weather Facility says on the Plains, record-setting warmth continues to dominate the northern half of the region, where today’s high temperatures could approach 80°F as far north as South Dakota. "Elsewhere, mild, dry weather prevails on the southern High Plains, while scattered rain showers linger across the southeastern Plains," USDA details.
In the West, USDA says impressive storminess is returning to northern California, although most of the precipitation is again falling as rain. "As a result, the water content of the high-elevation Sierra Nevada snowpack has not appreciably increased in March, although storms continue to boost soil moisture and increase reservoir storage," according to USDA.
In the Corn Belt, USDA says mild, dry weather prevails. "Recent and ongoing warmth has begun to coax winter wheat out of dormancy as far north as the Ohio Valley," USDA explains.
In the South, USDA reports ongoing heavy showers across much of Louisiana and Mississippi are resulting in a grave flood danger in several communities due to rising water levels and the threat of overtopped levees. "Storm-total rainfall has reached 10 to 20 inches or more from easternmost Texas to the northern Mississippi Delta," USDA elaborates. In stark contrast, warm, dry weather in the southern Atlantic States favors fieldwork and crop development, it continues.
In its outlook, USDA says relentless rain will continue to trigger severe to record flooding from easternmost Texas into the lower Mississippi Valley. "For the remainder of today, additional rainfall could total 3 to 6 inches or more in the lower Mississippi Valley and the central Gulf Coast region," USDA reports. During the weekend and early next week, rain will expand northward and eastward, bringing some 1- to 2-inch rainfall totals to the Midwest and Northeast, USDA continues. "Only light showers can be expected in the southern Atlantic States," it adds. Meanwhile, stormy weather will prevail through the weekend in much of the western U.S., where five-day precipitation totals could reach 4 to 10 inches in northern California, according to USDA. "Elsewhere, unusual warmth will continue to dominate the U.S., with record-setting high temperatures expected to persist through Monday across the nation’s mid-section," USDA continues.
