|The heat in the Central U.S. visits other portions of the country, giving relief to some and grief to others, while flash flooding poses a concern to a couple of other spots.|
A pronounced cold front currently sweeping across the Great Lakes and into the Northeast will weaken as it pushes east Thursday, keeping the cold air way up in Canada. However, it will bring some temporary relief to the East Coast, mostly along the I-95 corridor, in the form of afternoon and evening showers and thunderstorms. Temperatures will stay very warm in the Great Lakes with highs mostly in the 80s, and the 90s from Georgia up to Southern New England, where heat advisories are in effect on Thursday in New York.
A large portion of the U.S. from eastern Oklahoma across the Lower Mississippi Valley and into the Mid- and Deep South are under heat advisories and excessive heat warnings for Thursday. Expect heat indices to exceed 105 degrees in a few spots with temperatures mostly in the 90s.
The Central and Northern Plains will continue to see relief from the scorching heat over the past couple of weeks, where under mostly sunny skies temperature will reach into the 80s.
Flash flooding will continue to be a concern in Florida where showers and thunderstorms will fire up at any time. Temperatures in Florida will be mostly in the upper-80s to low-90s.
A series of weak storms will track through the Desert Southwest and Four Corners region, producing showers and thunderstorms, which will cause flash flooding in a few spots. The threat of flooding will shift into the Texas and Oklahoma Panhandles in the afternoon.
Building high pressure along the West Coast will maintain hot weather, where heat advisories are in effect Thursday for Portland, Ore. Temperature will be 10-15 degrees above normal, causing high temperatures to soar to the century mark. In fact, temperatures will hit the 105 to 110 degree range over the interior valleys of California and Oregon. Coastal spots will see temperatures mostly in the 70s with a slight chance of showers and thunderstorms from San Diego up to Los Angeles, with sunshine all day further north.
