Hurricane Isaac is about to come ashore in New Orleans (check out the current wind map for an arresting view), and by Friday night will be giving Illinois some much-needed rain:
As of noon on Monday, August 27, the track of Hurricane Isaac could pass through Illinois on Saturday. Of course, it won’t be a hurricane – just a tropical depression. Even so, large rainfall amounts are expected to fall in parts of Illinois and Missouri.
Then, for Labor Day Weekend, it looks to bake and then soak Chicago:
Post-landfall, the storm is expected to track north up the Mississippi Valley, spreading its torrential downpours into the Midwest with the heavy rain reaching the Chicago area by the weekend.
Prior to the rain, sinking air in advance of the storm should help boost Chicago temperatures into the mid-90s Thursday and Friday. That would raise the city's total of 32°C-plus days to 45, two shy of the record 47 logged in 1988. The heat is expected to solidify this summer's spot as the city's third hottest summer, behind 1955 and 1995 for the June-August meteorological summer period.
