Dry Conditions Continue

The warm and dry weather has begun to dry out our soil profile down to at least 12 inches according to our soil moisture sensors. This was recently verified when I attempted to dig a post hole! Although some areas of northern Illinois experienced torrential rains this summer, we’ve been near normal and with the recent dry spell, slightly below normal. This is reflected in the streamflows on nearby watersheds. Take a look at the following flow duration hydrographs for two nearby locations — Mazon River near Coal City and Kankakee River near Wilmington, IL. The black trace on the graphs indicate that flows are currently in the lower percentiles. It should be noted that we are approaching the time of year when streams typically experience their lowest flows. The following flow duration hydrographs are courtesy of the U.S. Geological Survey.

Record Hailstone in South Dakota

South Dakota Storm Produces Record Hailstone July 23, 2010 – link with pictures and nice meteorological discussion from NWS Aberdeen, SD.

National Weather Service Press Release:

South Dakota Storm Produces Record Hailstone

NOAA’s National Climate Extremes Committee, responsible for validating national weather records, has declared a hailstone found last week in Vivian, S.D., to be the largest in diameter and heaviest ever recovered in the United States.

Found after a July 23, 2010, severe thunderstorm by Vivian resident Les Scott, the hailstone is 8.0 inches in diameter and weighs 1.9375 pounds (1 pound, 15 ounces) with a circumference of 18.62 inches.

These measurements displace the previous hailstone record for weight, previously 1.67 pounds for a stone in Coffeyville, Kan., in 1970. They also surpass the record for diameter, which was 7 inches for a hailstone found in Aurora, Neb., in 2003. The Aurora hailstone still holds the record for circumference of 18.75 inches.

“I’m just glad nobody got hurt and hope the town will recover soon,” Scott said.

David Hintz, warning coordination meteorologist at NOAA’s Aberdeen weather forecast office said a local power outage likely led to the hailstone melting some before it could be measured. “Mr. Scott told me the area was littered with large hailstones and the largest had a greater diameter when he first found it. He immediately stored it and several others in his freezer, but a power outage caused some melting.”

After getting Hintz’ notice of a possible record hailstone, personnel at National Weather Service Central Region headquarters in Kansas City, Mo., requested activation of the National Climatic Extremes Committee to examine and judge Scott’s hailstone. Personnel from the Aberdeen office traveled to Vivian to measure and weigh the hailstone, and then turned their findings over to the three-person committee. After a thorough review of the facts, committee members certified its record-breaking status.

A break in the rain

Enjoy a rain-free week with sunny skies and lower humidities. A nice change from recent warm, muggy, and stormy conditions.

When Thunder Roars, Go Indoors. Lightning Safety Awareness Week.

Bill — Fri, 11 Jun 2010 18:13:48 +0000

Lightning Safety Awareness Week is June 20-26, 2010. Lightning is the second greatest cause of storm-related deaths in the U.S., killing more than tornadoes or hurricanes. Lightning also inflicts life-long debilitating injuries on many more than it kills.

NO PLACE OUTSIDE IS SAFE NEAR A THUNDERSTORM!

Go inside if you hear thunder, but keep away from corded telephones, electrical appliances, and plumbing. The second safest place is a vehicle with a metal roof and metal sides.

Cumulonimbus

Here’s an image of a distant cumulonimbus cloud (thunderstorm) to our southeast. A CoCoRaHS observer in Kankakee county had reported 0.30 inch of rain in ten minutes. Also shown is the radar image of the same storm located southeast of Kankakee, IL.
