The Weather Front On-Line
A low-pressure system drifting from the southern Plains into the upper Midwest will produce rain and wet snow. Some of the most significant snowfall accumulations will occur from northwestern Iowa to the western end of Lake Superior.
During the weekend, chilly conditions will linger in the East, while warmth will expand across the nation’s mid-section. Meanwhile, precipitation will gradually overspread much of the West.
By early next week, much cooler air will arrive in the West, while precipitation will spread as far east as the northern Plains and the central Rockies.
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.
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.
