...Heat Continues from Plains to Atlantic Coast...
Above-normal temperatures will continue to affect a large portion of the country from the northern Plains to the Mid-Atlantic over the next few days, with high temperatures today in the 90s to 100+ for many locations in these areas. Heat Advisories and Excessive Heat Warnings are in effect for many of the affected areas. Details...
...Record Heat Wave Continues Across Southern and Southeastern U.S...
Excessive heat warnings and advisories continue into the beginning of the week over much of the mid-Mississippi valley and southern states as an upper level ridge of high pressure remains firmly in place. Hundreds of daily high temperature records were broken this weekend as well as many all-time high temperature records. A weak cold front will slowly drag across the eastern U.S. for the beginning of this week and provide some relief from the intense heat, but will also serve as a starting point for potential severe weather development. Details...
...Severe Thunderstorms Possible Today from the Northern Rockies to the Carolinas...
A surface boundary separating excessive heat (temperatures above 100 degrees) in the southern United States with a milder airmass to its north will continue to be the focus for severe thunderstorms today. There are three main areas of concern, including the northern Rockies, the Mid-Mississippi River to Ohio Valleys and portions of the Mid-Atlantic into the Southeast, particularly the eastern Carolinas. The primary threats will be large hail and damaging winds, however an isolated tornado can not be ruled out across southern Minnesota and Wisconsin as well as northern Iowa and Illinois. Persons in all three regions should stay abreast on the NWS forecasts and warnings. Details...
...Risk of Severe Thunderstorms Continues Tonight As Heat Continues Across South...

...Another Day of Record Breaking Heat and Severe Thunderstorms...
High temperatures this afternoon will exceed 100 degrees across the mid/lower Mississippi River Valley eastward through the Mid-Atlantic and Southeast today.

Meanwhile, another round of severe weather will develop across the Ohio Valley and track into the northern Mid-Atlantic states, where damaging winds will be the primary threat. At this time, it appears the greatest risk will stretch from southern Ohio into Maryland and northern Virginia.
