September 12, 2013 by   - () Comments Off on Heavy Rains Expected for Parched U.S. West

Weather Summary: Several fronts moved across the central and eastern contiguous U.S. during the past week, bringing generally under an inch of rain to the Great Lakes and the Northeast. Heavy rain (2 inches or greater) fell across much of the Gulf Coast region, western Illinois, parts of the Northern Great Plains, and the higher terrain of the Washington and Oregon Cascades.

A very generous monsoonal flow into the Southwest brought light to moderate rain (less than 2 inches) to much of this region, with many reporting stations in Arizona receiving between 2-4 inches of rain during the past seven days.

Looking Ahead: During Sept. 12-16, heavy rainfall (2-4 inches) is anticipated over New Mexico, Colorado, western Kansas and far southern Texas. Generally light rain (0.5-inch or less) is expected across the Midwest, with high temperatures near- to slightly below normal.

For the ensuing five days (Sept. 17-21, 2013), odds for above normal precipitation are greatest across the central third of the contiguous U.S., the Gulf Coast, Pacific Northwest and northern Alaska, with maximum probabilities near 60% over southern Texas. Odds for below normal precipitation are greatest over the Northeast, mid-Atlantic region, upper Ohio Valley and southern third of Alaska.
