August’s start to follow July’s warm, dry mode

To no one’s surprise, July ended up to be warmer and drier than normal in Chicago. Though severe thunderstorms brought some much-needed rain to scattered localities, the overall drought worsened across the area during the month. The hot summer continued with seven 90° days at O’Hare and 10 at Midway during the month, highlighted by the region’s first 100º day in six years on July 24 when O’Hare soared to 102º and Midway to 104º.
August’s opening days promise a continuation of this hot, dry pattern with four consecutive days in the 90s expected through Thursday, along with little chance of significant rainfall.
Rain is falling in other parts of the nation. Up to 4 inches of rain flooded the streets of Sylvania in east-central Georgia Sunday, while vehicles were stranded in up to 3 feet of water in east-central North Carolina near Greenville after heavy thunderstorms passed through the area.

Hot, dry weather to regain control in Chicago

After a short respite, heat and humidity will return to Chicago this week for what appears to be a lengthy stay.
Afternoon maximum temperatures should climb into the 90s today—an event that promises to repeat itself each afternoon through Thursday.
For the most part, prospects for precipitation remain bleak, though an isolated thunderstorm could develop on a hot and increasingly humid Monday afternoon. The week’s best chances for rain will occur Thursday night as a cold frontal passage brings the city another refreshing break after a week of hot weather.
With the recent demise of Tropical Storm Franklin, the Atlantic Basin is currently tropical cyclone-free, but things could change quickly in the next day or two if a strengthening tropical wave approaching the Windward Islands becomes the eighth storm of the season: Harvey.

Summer weekends averaging 5 degrees above normal

More heat’s on the way. Temperatures and humidities will remain comfortable Saturday, thanks in part to easterly winds off Lake Michigan. But, with the ninth weekend of meteorological summer 2005 underway, the area is bracing for a new round of hot weather. A huge, rain-free dome of hot air continues to develop across the nation’s mid-section. Readings soared above 100° in parts of the Plains Friday, and this hot air is to begin building eastward.
Though daytime highs here won’t be as extreme as last Sunday’s 102°, surging humidities promise to make the five days of 90s predicted Sunday through Thursday rather uncomfortable: Gulf Coast-level dew points near 70° on the hottest of those days may send heat indexes near 100°.
Six of eight summer weekends this season have posted temperature surpluses, averaging nearly 5 degrees above normal. It’s likely this weekend will become the seventh to finish above normal.
