Weather Underground Forecast for Thursday, October 22, 2015
A low pressure system will shift across the southern Plains on Thursday, while a separate system affects the Northeast.
An area of low pressure will move east northeastward over the Four Corners and the southern Plains. This system will draw moisture from the Gulf of Mexico, fueling rain and thunderstorms over the Intermountain West, the Desert Southwest and the Plains. Heavy rain will develop across central and southern Plains, which will bring threats of flash flooding to central Texas, Oklahoma and south central Kansas. In addition to that, high elevation snow showers will develop across portions of the central and northern Rockies. A ridge of high pressure will build over the eastern Pacific. This system will influence a warming trend across California.
Meanwhile, a low pressure system will push east northeastward over the upper Great Lakes and the Northeast. This system will usher a mixture of rain and snow over northern New England. Light, scattered showers will also be possible across southern New England, the upper Midwest and the northern Mid-Atlantic as a cold front streaks across the region.
Just to the south, an onshore flow from the Atlantic will aid in the development of light showers across southeast South Carolina, eastern Georgia and Florida. The remainder of the Southeast will stay clear of precipitation.
Temperatures in the Lower 48 states Wednesday have ranged from a morning low of 21 degrees at Presque Isle, Maine to a high of 92 degrees at Edinburg, Texas
