Extended Hazard Outlook

Outlook Monday September 14th through Friday September 17th:

— Monday, September 14 through Thursday, September 17: Much of Utah and Colorado, most of Arizona and New Mexico, and small portions of northwestern Oklahoma and Texas: Heavy rain may create localized flooding and reduced visibility. Major highways potentially affected include I-8, I-10, I-25, I-40, I-70.

— Monday, September 14 through Thursday, September 17: From southeastern New Mexico and the central and southern Plains into the Lower Mississippi Valley and western Alabama: Hazardous heat may create challenging conditions. Southeastern New Mexico, Kansas, northwestern Texas, and much of Missouri are mainly affected Monday through Tuesday, while most of Oklahoma and Texas into the Lower Mississippi Valley and western Alabama may remain affected through Thursday. Major highways potentially affected include I-10, I-20, I-30, I-35, I-40, I-55.

— Monday, September 14 through Wednesday, September 16: Central Plains through the Upper Midwest and Great Lakes: Heavy rain may create localized flooding and reduced visibility. On Monday, the concern extends from southeastern South Dakota and eastern Nebraska through Minnesota, Iowa, and Wisconsin into Michigan; Tuesday through Wednesday, it shifts toward Kansas, southeastern Nebraska, Missouri, Illinois, Wisconsin, southeastern Michigan, and northern Indiana. Major highways potentially affected include I-29, I-35, I-55, I-65, I-70, I-74, I-75, I-80, I-90, I-94.

Extended Outlook September 19th through 25th:

Major highways potentially affected include I-8, I-10, I-25, I-40, I-70.

— Saturday, September 19 through Sunday, September 20: Northern Plains through the Upper Midwest and Great Lakes: Much below-normal temperatures may develop across much of North Dakota, northeastern South Dakota, most of Minnesota and Wisconsin, and much of Michigan, creating cold-weather travel concerns and issues for exposed plumbing. Major highways potentially affected include I-29, I-35, I-75, I-94.

— Saturday, September 19 through Tuesday, September 22: Northern New York and northern New England: Much below-normal temperatures may develop across northern New York, most of Vermont and Maine, and much of New Hampshire, creating cold-weather travel concerns and issues for exposed plumbing.

Confidence in the Extended Outlook:

Confidence is average for the earlier period, with generally good large-scale agreement. Confidence decreases later in the outlook because of a more complex transitional pattern and greater uncertainty in how the western U.S. pattern evolves, along with uncertainty associated with the active eastern and central tropical Pacific.
