Smooth sailing today with more sun & less humidity. Tomorrow is another story. The Storm Prediction Center has outlooked the southern half of our area for a slight risk of severe weather. A warm front will be pushing northward toward Chicago during the afternoon and good trigger some strong storms.
Snakes, not storms, are the problem down in Texas. The southern third of Texas is in an “extreme” to “exceptional” drought. There has been an increase in poisonous snake bites that may be attributed to the dry conditions. It seems the snakes normal sources of hydration have evaporated so they now are venturing onto watered lawns. A rattlesnake can bite twice. There is the initial bite then the bite in the wallet. A vile of antivenom can cost over $1000.
Sunshine returns Tuesday in the wake of drenching thunderstorms which, for the hardest hit sections of the Chicago area, meant two-day rains in excess of 2 inches. The thundery rains marked an end to the driest mid-July to mid-August period here in the 75 years since 1934. Heavier two-day totals in the metro area included 2.85 inches in Sandwich in DeKalb County, 2.08 in Naperville and 1.96 at Lisle. But those totals paled in comparison to those tallied Monday after a series of thundery cloudbursts swamped in north-central Indiana. That region bore the brunt of Midwest storm outbreak Monday. Parts of the Goshen area were hit by seven waves of downpour-generating thunderstorms that drenched a few locations with more than a half-foot of rain in just 12 hours—more than what typically falls in all of August. Near Leesburg, Ind., 6.45 inches topped rain gauges while 5.43 inches was measured near Syracuse, 4.79 inches in Goshen and 4.25 near Warsaw, Ind. Rainbows were spotted over many sections of the Chicago area as the setting sun interacted with a band of retreating rains.
Bill gaining strength
Hurricane Bill continued strengthening far at sea in the tropical Atlantic Monday. The storm, situated 975 miles east of the Cape Verde Islands, is headed for major hurricane status—but is on a track that would keep it away from the U.S.
Summers in the 1930s were very hot. What was the tally of “century days” in
Paul Sarewich, Chicago
When it comes to 100-degree occurrences in Chicago, the decade of the 1930s yielded a bumper crop of 100-degree days that is unrivaled by any other decade in the city’s 139 years of documented weather history. From 1930 through 1939, 37 “century days” were registered at Midway Airport. And in the 1930s two blistering summers stand out: 1934 and 1936. Each of them produced 11 days of 100-degree heat that were without precedent in two dangerous aspects, duration and intensity—six consecutive 100-degree days, July 20 to July 25, 1934;
and eight consecutive days, July 7 through 14, 1936. The daily highs during the 1934 period were 103, 108, 104, 109, 107, 105 and in 1936 the highs were 102, 106, 100, 106, 107, 100, 102, 104.

A few showers are still possible, but the threat of strong thunderstorms and has ended for the rest of the evening across Chicago and all of Northern Illinois.
All of the heavier thunderstorm activity has shifted into Northern Indiana where heavy downpours will be likely in some of the stronger storms. While heavy rain remains a concern in Indiana, the threat of any significant severe weather (wind, hail or tornados) is very low.
