43 deaths tied to heat wave over last 2 weeks In the hot zone emergency room visits are on the rise as the number of heat-related deaths rose, especially among the sick and elderly. Cooler weather was on the horizon for the Midwest, but not before two weeks of oven-like temperatures had taken their toll: at least 43 deaths were tied to the heat over that period, according to a list compiled by the Weather Channel. Friday also saw the 9th straight day at 100 degrees or above in St. Louis, Mo., and the third straight day above 100 in Chicago. Virginia saw the most heat-related deaths with 10, followed by Maryland (9) and Illinois (6). Three of the dead were children, with the rest adults between 45 and 83. Temperatures in the Midwest should be back in the 80s by Sunday -- but only after another hot round on Saturday as the heat wave shifts to the East Coast. Washington, D.C., on Saturday could break its all time record of 106, the Weather Channel reported. Same with Pittsburgh (103) and Louisville, Ky., (107). The heat wave has included several rounds of storms that add to the misery.

Indiana, Virginia and West Virginia on Thursday saw new storms and new power outages, while the same happened in Michigan on Wednesday. St. Louis, Milwaukee, Minneapolis, Chicago and several other Midwest cities already have broken heat records this week. The city hadn't seen 9 straight days at or above 100 since 1936. In Chicago, three straight days above 100 hadn't been seen since 1947 and the city has no longer stretch on record. There's a slight chance that could be broken Saturday.
