Weather Underground Forecast for Friday, October 14, 2011.
The Eastern US will remain wet on Friday as a trough of low pressure strengthens over the Great Lakes. Flow around this system will continue pushing a cold front eastward, starting the day over the Appalachians and moving offshore by evening. The northern edge of this front will linger over the Northeast and continue triggering widespread scattered showers throughout the day. At the same time, the back side of this system will continue to push a few disturbances through the Great Lakes. Thus, the storms in the Southeast will taper off by evening, but persist for the Great Lakes, Midwest, and Northeast. Rainfall totals will range from 0.5 to 1 inch across the Northeast.
Behind this system, a ridge of high pressure will remain the dominant weather feature for the West Coast, Rocky Mountains, and Plains. The leading edge of this system will create some strong winds for the Northern Plains and Upper Midwest, due to the change from low to high pressure. Expect winds to vary around 20 mph, with gusts between 30 and 35 mph. A gradual warming trend will accompany this system.
In the Northwest, a weak trough of low pressure moves eastward over the Northern Rockies from the Pacific Northwest. Expect scattered rain showers with snow showers at the highest peaks. Temperatures in the Lower 48 states Thursday have ranged from a morning low of 21 degrees at Big Piney, Wyo. to a high of 100 degrees at Santee, Calif.
