Hundreds of daily high temperature records were broken this weekend as well as many all-time high temperature records.

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.

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. Persons in the region should remain alert to the latest forecasts and warnings from the NWS.
