One more steamy day is forecast for the Quad-Cities before temperatures turn cooler.
Tuesday's forecast calls for a high of 90 with a 50 percent chance of a thunderstorm and rain. Precipitation chances rise to 60 percent Tuesday night, with more than half an inch of rain possible.
Partly cloudy skies on Wednesday, however, will keep the mercury from moving much higher than 81 degrees with north/northwest winds. A 20 percent chance of a thunderstorm or rain is forecast.
Partly cloudy skies also are foreseen for Thursday, with a high again around 81 degrees but no precipitation chances in the forecast. Thursday night's low is forecast at 59 degrees before Friday's temperatures – again – climb only to around 81 degrees under clear skies.
Temperatures are forecast for the lower or mid-80s on Saturday and Sunday, with fog possible Sunday night.
