The same hot air mass responsible for 89-degree highs Monday-the warmest
temperatures to date in 2009 at O'Hare International and Midway Airports
tightens its grip on the Chicago area Tuesday and Wednesday. Heat
advisories have been hoisted for all but lakeside areas where light
onshore (easterly) afternoon winds should temper highs to the 80s while
90s occur inland. Wednesday may prove to be the hottest of all with heat
indexes approaching a dangerous 106 right up to the lake.
Monday's heat and humidity in southwestern Iowa reached extreme levels
when the country's highest dew point, 82 degrees, combined with a high
of 93 degrees to produce a 117-degree heat index at Shenandoah, Iowa.
Florida heat
After several days of suffocating heat and humidity, Florida is in line
for somewhat cooler weather Tuesday. More temperature records tumbled
Monday with Vero Beach leading the heat parade with a record high of 102
degrees and a heat index of 111.
