The nation’s weather

Weather Underground Forecast for Friday, June 21, 2013.

Expect more storms to develop across the North-Central U.S. on Friday.

A low pressure system over the Plains will continue spreading active weather over the Upper Midwest as it pushes a warm front northeastward throughout the day. This will pull more warm and moist air northward from the Gulf of Mexico, maintaining showers and thunderstorms across Minnesota, Wisconsin, and into the Midwest and Great Lakes. This system has a history of producing quarter size hail and wind gusts over 50 mph, thus, some of these storms will turn severe with strong winds, large hail, and periods of heavy rainfall.

Behind this system, a cold front extends from this system and will allow for storms to also continue across the Northern and Central Plains. Fire danger will remain high south of this front across the Four Corners due to another hot, dry, and breezy day.

In the Southeast, a cold front slowly weakens over the Gulf of Mexico, Florida and the Carolinas. This will allow for a few more scattered storms to develop from southern Louisiana through the coast of North Carolina. Severe storms are not anticipated in these areas as this system does not have a history of large hail and strong winds. However, periods of heavy rainfall may persist across the region.

Temperatures in the Lower 48 states Thursday have ranged from a morning low of 24 degrees at Truckee, Calif. to a high of 102 degrees at Tucson, Ariz.
