Weather Underground Forecast for Friday, September 10, 2010.

A low pressure system in the North will bring active weather to the Central US on Friday. The system develops over the Northern Rockies and will strengthen as it moves into the Plains. It will take a more northeastward track, moving into Canada, but flow around this system will produce a cold front that will push through the Northern and Central Plains, reaching the Upper and Mid-Mississippi River Valley by Friday night. Expect scattered showers and thunderstorms to develop along this front, some of which may turns severe with strong winds and heavy rains.

Meanwhile, to the south, expect rains and strong winds to persist over the South, as the remnants of Tropical Storm Hermine continue moving eastward from the Lower Mississippi River Valley to the East Coast. Expect rainfall totals to reduce around this system as it has lost most of its strength, however, residual atmospheric moisture will allow for some scattered showers to persist. The South will remain hot and humid with highs in the 90s, while the North will see cooler conditions with highs in the 60s and 70s. In the Northeast and New England, expect high pressure and sunny skies to persist as high pressure dominates. Expect a few patchy clouds with highs also in the 60s and 70s.

In the West, critical fire conditions persist over northern Colorado and southern Wyoming. High pressure over the Rockies will bring more gusty winds with dry surface conditions. Expect strong winds ranging from 15-20 mph with gusts up to 30-40 mph.

Temperatures in the Lower 48 states Thursday ranged from a low of 30 degrees at Hibbing, Minn. to a high of 101 degrees at Laredo, Texas.
