With the upper-level jet stream flow poised to hold out of the northwest,
Canadian-origin high pressure air masses are expected to influence Chicago's weather
into next weekend. There should be only minor day to day variations in temperatures,
averaging near or slightly below normal for this point in August. Low pressure midweek
may give a 48-hour period of unstable weather featuring periods of showers and
thunderstorms starting later Tuesday extending into Thursday. Bathers along the south
end of lake Michigan are cautioned to watch for rip currents today and Monday as north
winds build waves over the open water.

a 16-day string of 80s--likely to be 2008's longest.
METEOR SHOWER SIGHTING LIKELY
According to Dan Joyce of Triton college's Cernan Earth and Space Center, 2008 Perseid
meteor shower activity will peak later Monday and early Tuesday.
