USDA's Joint Ag Weather Facility says on the Plains, freeze warnings are in effect early today in parts of northern and eastern Oklahoma. "A day earlier, on March 27, temperatures locally dipped below 20°F on the southern High Plains, maintaining a stressful period for winter wheat that has included developing drought and temperature extremes," USDA details. However, portions of the southern Plains—especially northernmost Texas—also received beneficial weekend snow, according to USDA.
In the West, USDA reports rain and snow showers continue to push inland across the northern half of the region. "In contrast, warm, dry, breezy weather prevails in the Southwest, resulting in an elevated to critical risk of wildfires," USDA explains.
In the Corn Belt, USDA says a chilly rain is ending across Michigan. "Elsewhere, mild air is expanding across the western Corn Belt, while cool, cloudy, breezy weather covers the eastern Corn Belt," USDA continues.
In the South, USDA explains rain has mostly ended, although a few showers linger in the southern Atlantic States. "Elsewhere, cooler but dry weather favors a limited return to spring fieldwork, following recent rainfall," USDA continues.
In its outlook, USDA says a storm system and its trailing cold front will exit the eastern U.S. later today, except for lingering precipitation into Tuesday across northern New England and southern Florida. "Meanwhile in the West, a developing storm will produce heavy snow on March 28-29 across the northern Intermountain region," USDA details. By midweek, the storm will emerge across the nation’s midsection, with snow possible from the northern Plains into the upper Midwest, according to USDA. Farther south, the threat of wind-driven wildfires will shift from the Southwest to the southern High Plains, while locally severe thunderstorms could affect portions of the nation’s southeastern quadrant on March 30-31, USDA elaborates. "As the storm moves eastward, the western U.S. will experience a return to dry weather and a late- week warming trend," USDA reports.
