Heat Building from the Plains into the Northeast

13 Jun 2017, 10:38 am

The warmth of summer is spreading across much of the country as humidity builds. Record highs were set Monday from New England into the Middle Atlantic.

Chicago felt its hottest day yesterday since September of last year as the mercury reached well into the 90s. For today, a Heat Advisory has been issued near the Mississippi River in Iowa and Illinois and also in portions of the Northeast.

The thermometer will soar well into the 90s from Boston to Baltimore. As dew points reach tropical levels in the 70s, the heat index may climb above 100.

The tropical 70+ dew points have also pushed into the Upper Midwest. With highs into the middle 90s, the heat index may climb as high as 102 near the Mississippi River in Illinois and Iowa.

On Wednesday, there will be a break from the heat as temperatures fall to comfortable levels into the 70s and 80s in the Northeast. Lower 90s will be found in Iowa and Illinois, dropping just enough to keep the heat index out of the triple digits.
