The Weather Front On-Line (May 2010)

Rainfall potential on Memorial Day...

A warm, dry start to the Holiday Weekend...

A slight cool-off for the Midwest...

Cool weather will persist through week’s end in the West Coast States, but temperatures will rebound to above-normal levels by early next week. Meanwhile, a warm weather pattern across the Plains and much of the Midwest will be replaced by slightly cooler conditions.

Summer-like warmth across the Corn Belt...

Across the Corn Belt, scattered showers and thunderstorms are grazing the far western areas of the region. Across the remainder of the Midwest, very warm, mostly dry weather favors planting activities and corn and soybean emergence and development.

A major pattern shift ahead...

A major weather pattern change for the Midwest will take place during the next few days.

Cool, wet pattern in position, for now...

A slow-moving storm system will drift from the central and southern Plains into the Great Lakes region by week’s end. Rainfall near the path of the storm could total 1 to 4 inches.

Cool, wet weather impacting Summer crops...

According to the Illinois Office of USDA’s National Agricultural Statistics Service, cooler-than-normal temperatures with rain last week caused some low land flooding and ponding in fields. Many producers are predicting a small amount of corn replanting will need to be done.

More cool, wet weather, then a change...

Heavy rain, strong or severe storms ahead...

A large, complex storm system will generate additional late-season snow in the central Rockies, while a mixture of rain and wet snow falls from the central High Plains into the Dakotas and Upper Midwest.

A wet pattern continues for now...

Two periods of possible severe weather exist.

The first will be late Wednesday night as a warm front moves north through Illinois. Large hail and strong winds will be possible.
