USDA's Joint Ag Weather Facility says in the Corn Belt, unusually cool, breezy conditions persist. "March temperatures averaged more than 10°F below normal in the far upper Midwest, including the Red River communities of Grand Forks (11.0°F below normal) and Fargo, North Dakota (10.5°F below normal)," USDA reports. In addition, monthly temperatures averaged at least 8°F below normal in portions of the upper Mississippi Valley, including Waterloo, Iowa (9.2°F below normal), USDA adds.
In the West, USDA says a few showers are occurring across northern California, southern Oregon and the Intermountain region. "Elsewhere, warm, dry weather favors fieldwork and crop growth in the Northwest and Southwest," USDA adds.
On the Plains, USDA says warmth lingers across Texas, but below-normal temperatures are limiting winter wheat development across the remainder of the region. "Today’s low temperatures fell to near 0°F in parts of North Dakota, where snow remains on the ground," USDA elaborates. In Grand Forks, North Dakota, the current snow depth is 7 inches, USDA continues.
In the South, USDA reports showers and thunderstorms are starting to move offshore but linger across portions of the southern Atlantic states. "In the wake of the departing storm system, cooler weather is returning to the South," USDA explains.
In its outlook, USDA says unusually cool conditions will persist through mid-week in most areas east of the Rockies. "During the second half of the week, warmth will return to the High Plains," USDA adds. Toward week’s end, markedly warmer air will arrive across the South, East and lower Midwest, according to USDA. "A surge of moisture will accompany the warmer weather, with five-day precipitation totals of 1 to 3 inches possible from the Southern Plains to the southern Atlantic states," USDA continues. Meanwhile, USDA says only light precipitation will fall across the northern and central Plains and the Midwest. "Elsewhere, showers in the Northwest will contrast with dry weather in the Southwest," USDA adds.
