On the Plains, Friday morning’s low temperatures fell below 20 degrees as far south as Nebraska. However, warmer air is expanding across the northern High Plains. Dry weather favors summer crop harvesting but continues to threaten the proper establishment of the central and southern Plains’ winter wheat crop.
For the remainder of the week, rain will gradually shift from the South into the East. Storm-total rainfall may exceed an inch in parts of the East, with higher totals possible along the Atlantic Seaboard.
During the weekend, much colder, windy weather will prevail in the storm’s wake across the eastern one-third of the U.S.
Most soils across the state continue to be in need of additional moisture due to the high winds last week and rapid drying.
Across the Corn Belt, dry weather favors a limited return to fieldwork, following a stormy spell. Winter wheat across the eastern Corn Belt is benefiting from recent topsoil moisture improvements, but additional precipitation will be needed to ensure proper crop establishment.
A new record was set on Tuesday for the lowest barometric pressure in a extra-tropical (non-tropical) storm in the mainland U.S.
On the Plains, a developing low-pressure system over the Dakotas is producing scattered showers across the northern half of the region. Meanwhile, warm, breezy weather prevails on the southern Plains in the wake of last week’s rainfall.
Low pressure on the Plains will send scattered showers and thunderstorms into Illinois Saturday. The precipitation will expand eastward, but areas southeast of I-70 will most likely remain dry. Temperatures will return to above normal levels over the weekend.
A weak front will slide into the region Sunday and cool temperatures back down into the upper 60s to lower 70s. A few rain showers are possible early next week.
Meanwhile, rain is still needed in parts of the Ohio Valley to encourage germination of newly planted winter grains.
