Weather Underground midday recap for Wednesday, June 26, 2013.
Rain and thunderstorms picked up across the Ohio Valley and parts of the Great Lakes this Wednesday morning and afternoon as the latest in a series of weak shortwaves in southern stream flow approached the area. Heavy rains accompanied strong, slow moving storms across Wisconsin, Illinois, Indiana, and parts of southwestern Ohio and led to increased flood risks through the afternoon. Much of this region remained under Flash Flood Watches as storms rolled through the afternoon, while areas just north of Chicago were placed under a Flash Flood Warning as soaking rains drenched the area. Meanwhile, showers and thunderstorms also began to pick up across the Northeast through the afternoon with Flash Flood Watches and Warnings issued for northern New Hampshire and southwestern Maine. The Storm Prediction Center has issued a slight risk of severe thunderstorm development from parts of the Upper and Mid-Mississippi Valley through the Ohio Valley into New England and the Mid-Atlantic States with threats of locally damaging wind gusts and hail.
Elsewhere in the eastern half of the nation, an upper level disturbance over the Southeast triggered showers and thunderstorms in parts the Southeast and Central and Eastern Gulf Coasts through the day.
Out West, rain showers in northern California and Oregon waned through the day, while a moist and unstable airmass resulted in bursts of heavy rain in Washington. To the south, much of the Desert Southwest remained under a variety of Excessive Heat Watches and Warnings in anticipation for a big warming trend forecast to begin Friday.
Temperatures in the Lower 48 states Wednesday have ranged from a morning low of 37 degrees at Kremmling, Colo. to a midday high of 106 degrees at Wink, Texas
