The Weather Front On-Line (October 2010)
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.
A couple of upper level disturbances will bring more cloudiness compared to recent days. A possibility of some rain exists tomorrow night and Wednesday. Temperatures will continue well above “normal” through mid-week before cooler, more seasonal air arrives.
On the Plains, unseasonably warm, dry weather continues to favor summer crop maturation and harvesting as well as winter wheat planting and emergence. However, rain will be needed soon across parts of the central and southern Plains to promote proper winter wheat establishment.
Shower activity will continue to subside in the Northeast but continue through week’s end in parts of the West.
During the weekend, isolated showers will develop on the northern and central High Plains, while a new round of rain will arrive in the Pacific Northwest.
Last week was cool and dry for much of the state, allowing harvest to continue at an exceptionally rapid rate. With harvest progressing, many producers have started fall tillage, fertilizer applications, and wheat seeding.
Corn harvest advanced to 74 percent complete, compared to just 5 percent last year and a five-year average of 31 percent.
