\"Dangerous<\/a><\/p>\n

A dangerous heat wave has locked in across the central United States and is forecast to expand eastward through the week, reaching
\n the East Coast in time for the Fourth of July weekend. The National Weather Service has Extreme Heat Warnings in effect from the
\n Dakotas and Nebraska across the Upper Midwest, with Extreme Heat Watches already posted for the Northeast beginning midweek.<\/p>\n

The heat is being driven by a strengthening upper-level high-pressure ridge. Afternoon temperatures will climb into the 90s and
\n low 100s, with heat index values forecast as high as 105 to 115°F across the southern Plains, the mid-Mississippi Valley, and
\n eventually the Mid-Atlantic. Much of the central and eastern U.S. rates Major to Extreme on the NWS HeatRisk scale, its two highest
\n levels.<\/p>\n
