Weather Underground Forecast for Thursday, May 30, 2013. A strong storm will continue moving through the middle portion of the country Thursday, allowing the threat for severe weather to continue as well. The Storm Prediction Center has issued a slight risk of severe weather from Oklahoma through eastern North Dakota, and then eastward through much of Illinois and southern Wisconsin. This means that severe thunderstorms could develop in the region, and may be accompanied by strong winds, large hail, heavy rain, and even tornadoes. Residents in the Plains and Upper Midwest should monitor local weather conditions and be prepared to protect life and property should severe thunderstorms develop.
Farther to the north, heavy rain will fall through Montana and may be accompanied by a few areas of high elevation snow in the adjacent northern Rockies.
A few showers will also be possible in the Northwest, but will not be widespread in nature.
A strengthening high pressure system over the Southwest will allow a significant warming trend to begin. This warming trend will push afternoon temperatures well above 100 degrees for many areas of the Southwest through the weekend. Very warm temperatures will also be experienced during the weekend along the California coast.
Warm temperatures are expected along the eastern seaboard with afternoon temperatures soaring into the 80s and 90s from the New England coast through Florida. The Southern Plains will rise into the 80s and 90s, while the Northwest will see temperatures in the 70s and 80s.
Temperatures in the Lower 48 states Wednesday have ranged from a morning low of 26 degrees at Grand Canyon, Ariz. to a high of 95 degrees at Lubbock, Texas
