First Heavy Frost

Frost around TreesFirst Frost

As forecast, we experienced our first hard frost this morning. The morning low temperature was 29 degrees. The bird bath froze! This was possibly the latest frost that I remember in the 10 years we have been here. I’ll need to check my records to verify. Check out frost around the trees in the first picture. Note the lack of frost under the Swamp White Oak( Quercas bicolor…one of my favorite trees) due to the heat trapping effect of its large leaves. Now look at the smaller Washington Hawthorn (Crataegus phaenopyrum), the tree on the left with the red fruit . Since most of the leaves have fallen off, there is no way to prevent the radiative cooling overnight.

A persistent line of altocumulus clouds Tuesday evening 10/23/07 made for a beautiful sunset.

Unusual October Storms

Friday, October 19th, 2007

Severe weather passed east of this station by only about 5 miles yesterday. An intense storm system spawned severe weather late in the day on Thursday Oct 18th. I was able to get a few good pictures of the storms as developed and moved to the northeast at speeds of up to 55 mph. To the left of the rainbow in the first picture is a milky white area known as a hail shaft. Hail was reported between penny and nickel size in Coal City and at I-55 and Lorenzo Road from this storm.


The second picture shows a building cumulonimbus or thunderhead. The colors were spectacular!


Rain at Last!

Tuesday, October 16th, 2007

A nice soaking rain overnight of 0.86 inch. An active weather pattern is shaping up for the late Wednesday through late Thursday period with more rain and a chance for severe weather.

Lack of Rain

Sunday, October 14th, 2007

I checked my records today and the last “good” rain we had was on August 24th. I categorize a good rain this time of year as anything greater than 1/2 inch. We certainly could use some moisture before the ground freezes.

Windy Conditions

Tuesday, October 9th, 2007


Strong winds and much cooler temperatures will bring an abrupt end to the summer like temperatures of the last several days. A strong cold front will provide winds between 15 and 25 with higher gusts likely.

And the Heat Goes On…

Sunday, October 7th, 2007


Yesterday’s max temperature topped out at 90 and a high near 90 is expected once again today. This is about 20 degrees above normal for this time of year. A cold front expected Monday night should bring cooler temperatures for next week.

Those Warm October Winds(?)

Don’t expect any frost on the pumpkin this week. Daily high temperatures should be in the 80’s compared with the normal high of around 67.
The normal low is around 46.sm_pumpkin1.JPG
