The pattern of hot and dry in the south with heavy rainfall to the north of the high-pressure system continued over this past week. The highest precipitation amounts were from eastern Iowa and southeastern Minnesota to the east through southern Wisconsin, northern Illinois, to Ohio and West Virginia. Localized areas in this region received 6 to 8 inches of rainfall. Northeastern Kansas and northern Missouri received 3 to 5 inches, with western Nebraska to southeastern Montana picking up 2 to 3 inches. Monsoonal rain also fell in eastern Arizona to central New Mexico. Southern Florida also received several inches of rain over the week. Precipitation was very spotty and generally light, however, in Texas, Oklahoma, Louisiana, Arkansas, southern Missouri, and western Tennessee and Kentucky. Most of the west coast states had little rain.Most of the south was again 5 to 10F above normal last week, peaking at over 15F above normal in parts of southern Missouri. Several states are setting records for continued warmth during this late summer to early fall period. The rest of the continental U.S. had generally near-normal temperatures.

Forecast

The next five days are forecast to be wet along the northeastern coast from a nor’easter. The northwest is also predicted to receive needed precipitation. Remnants of a tropical system will provide significant moisture into the Four Corners states and the western Great Plains with heavy rainfall in the forecast. Parts of the northern Great Plains are also forecast to receive welcome precipitation. Areas with little rain in the forecast over the next five days are much of Texas and Louisiana, around the Great Lakes, and California and Nevada. The south and southwest should continue to have above normal temperatures, with cooler temperatures in the northeast and the northwest.

The 6- to 10-day outlook (September 29 to October 3) favors above normal temperatures over the southern half of the continental U.S. as well as the northeast. Hawaii is also likely to have above normal temperatures. The Great Basin area could have below normal rainfall, while above normal is possible over much of the central U.S. Both Hawaii and eastern Alaska are also favored to have above normal precipitation during this period.

Midwest

Southern Missouri was generally hot and dry this past week, with drought conditions deteriorating over much of the region. However, northern Missouri was wet leading to improvement in drought conditions. Southern Minnesota, eastern Iowa, southern Wisconsin, and northern Minnesota received significant precipitation, with over 8 inches falling in northeast Grant County, Wisconsin. The dry categories were thus improved in these areas. Northern Wisconsin, on the other hand, was dry with localized deterioration and the introduction of a small area of exceptional drought.
