Intense Heat to Shatter Records in the East

A large ridge of high pressure over the Mississippi Valley will cause heat to build and slog eastward over the next several days. Places in the Mid-Atlantic will see record highs broken and heat indices to easily surpass 100 degrees early in the new workweek. The peak of the heat wave will be on Monday and Tuesday where heat indices of over 110 degrees will be observed in many locations. 

Under this ridge of high pressure, almost unlimited near summer solstice sunshine will cause temperatures to soar. When you combine this heat with abundant moisture from recent rains, heat indices will soar to dangerous, life threatening levels.

Record high temperatures will be found for portions of the Mid-Atlantic, Northeast, Ohio Valley and the Great Lakes. With Monday and Tuesday being the peak of the heat wave, a few locations that will see record challenging or breaking warmth. Allentown, Pa., with a forecast high of 99 degrees, is expected to break its record high of 96 set just last year (2024). Heading several hundred miles due north, Albany, N.Y. will see its record high of 96 degrees set in 1888 to either be challenged or broken by a forecast high temperature of 97 degrees. 

In the Mid-Atlantic, Washington D.C.'s forecast high temperature of 100 degrees on Monday will break or challenge its record high temperature of 99 degrees set last year. Baltimore's forecast high is also expected to be 100 degrees, which would break their record high of 98 degrees also set last year. 

Looking further west, Columbus, Ohio's forecast of 96 degrees is expected to tie their record set in 1948. Finally, Athens, Ohio's record high temperature of 98 degrees (set in 1988) is expected to be threatened by a forecast high temperature of 97 degrees. 

If you are in one of these areas experiencing unseasonably hot temperatures, it will be important to stay hydrated and cool. Avoid exposure to the sun from late morning into the early evening. Take frequent breaks in the A.C. or shade. Eat and dress lightly. Use sun protection if outdoors. Never leave kids or pets unattended and remember to “Look Before You Lock!” Recognize the signs of heat-related illness.
