The week ahead will be very springlike, starting out with perhaps the warmest day of the week followed by what may turn out to be the coldest day tomorrow. If clouds from an approaching low pressure system hold off, highs today may warm well into the 70s. Then as low pressure passes to the south Tuesday, chilling north winds will make 50° temperatures “feel” like the 40s. Midweek weather should be very seasonable, but on Friday a low pressure center will “cut off” or become detached from the main jet stream flow in Canada, centering over the western Great Lakes where it will drift slowly east over the weekend, giving Chicago another “cool down” along with extensive cloudiness and frequent showers.
The Atlantic hurricane season approaches, but it’s now for Australia as the country’s north coast braces for monster Category 5 Tropical Cyclone Monica, carrying wind gusts well over 200 m.p.h. and 30-foot waves as it approaches the mainland today.
