Only 0.01 Inches Of Rain So Far This June

CHICAGO (CBS) -- If you're seeing brown grass and dusty soil, it's not your imagination – it's bone dry out there.

CBS 2 Meteorologist Mary Kay Kleist says only 0.01 inches of rainfall have fallen since the month began.

The only drier early June was in 1988, when no rain fell at all from June 1 through June 15. That year that was infamous for an extreme drought and heat wave that drove the temperature above 100 degrees in Chicago for many days during the summer.

The second driest June 1-15 as of now was in 1922, when 0.04 inches of rain fell. But this year could end up beating it.

The drought has already made for hazardous conditions. On Tuesday afternoon, brush fires made Route 59 impassable in North Barrington, and shut down Union Pacific-West Line Metra trains in Geneva.

But dry though it may be, conditions are cool and comfortable – at least for now. Kleist says it was 69 degrees at O'Hare International Airport, and a lake breeze of 15 mph will bring even cooler temperatures to the lakefront, topping out at 66.

But don't look for the cool weather to last. After an overnight low of 57 with a high-pressure system hovering over the northern Great Lakes, a warm front will pass through and open the door for another weekend of extreme heat.

The high for Wednesday is only 72 officially, but the high for Thursday is 81, Friday 88, Saturday 90, Sunday 91, Monday 90 again, and Tuesday 87.

There is a tiny chance of rain on late Sunday night, but the chance is only 30 percent.
