We should climb to near 40 today before more arctic air arrives tonight. Looking back at 2009 so far, NOAA scientists expect the year to rank among the top ten warmest years globally. Not only has this been a warmer than average year but the 2000-2009 decade will be the warmest on record.
Check out NOAA's report and notice that 2009 for Illinois is actually colder than average:
Gusty west and northwest winds will make it really feel like fall for the next few days. According to our WeatherBug network, several locations have reported gusts close to 50 mph since midnight.
Here are some of the stronger gusts through 6 AM today:
Gust Location
49 mph Chicago Heights
48 mph Naperville
48 mph Burlington
48 mph Geneva
A wind advisory is in effect for most of us from 10 AM until 7 PM today. A lakeshore flood warning is in effect for Lake and Porter county Indiana from 10 AM until 1 PM today. Strong winds could produce waves 12 to 15 feet high. The National Weather Service warns, "DOCKS...PIERS...AND BREAK WALLS WILL BE DANGEROUS PLACES TO BE
DURING THE HIGH WAVES AND SHOULD BE AVOIDED."

NOAA has just completed the final phase of a nine-year, $180 million plan to upgrade the computer system that powers our nation's forecasts for the National Weather Service. These aren't your parent's computers. These IBM supercomputers would fill about half of a tennis court and are 34 times more powerful than the most powerful supercomputer that existed just 10 years ago. According to NOAA, it would take someone with a calculator 3 million years to match the number of calculations the new "Stratus" supercomputer system can whip out in one second.
All this extra power should enable the use of more complex weather models that should improve accuracy and lead to more lead time for severe weather warnings.
It was just last week when we lamented the lack of rain from mid-July through mid-August. The first half of this month started out with about half the rain we normally see. We made up for that a bit yesterday, some areas more than others. O'Hare's .31" or rain yesterday brings the months total to 1.91". That's better but still about an inch below average for the month so far.
Here are some heavier rainfall amounts from Wednesday according to our WeatherBug network:
1.90" Flossmoor
1.11" University Park
1.00' Burlington
.98" Markham
However, the rain was accompanied by some severe weather. Spotters reported tornadoes near Elburn and Chesterton. There were almost a dozen tornadoes reported across the midwest according to the Storm Prediction Center in Norman, Oklahoma.
We are not out of the woods yet. The SPC has a portion of our area outlooked for a slight risk of severe weather today.
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.
One good byproduct of our cool summer is a relatively quiet severe weather season. According to the Storm Prediction Center, there have been 21 deaths from tornadoes so far this year. That compares to 122 at this point last year.
It was two years ago that an EF5 tornado struck Greensburg, Kansas. The storm decimated the town. To view a full length documentary on the Greensburg tornado, check this out.
It may seem like we skipped summer this year. We have had only three days so far with highs in the 90s. This July ranked as the second coolest since the official weather station for Chicago moved inland from the lakefront in 1942.
Summer will surge back though this weekend. If we hit the predicted 95 on Saturday, that would make it the hottest day since August 2nd, 2006 when O'Hare hit 97.
Today won't be quite as hot but it could be the warmest day since June 25th when we hit 94.

That is the question everyone seems to be asking lately. So far this year, there has only been 26 days with highs of 80 or warmer. That ties 1942 for the 2nd fewest days of 80 degree or warmer highs. We should normally have around 40 by now. No 90 degree days yet this July either. The warmest day this month occurred on July 6th when we hit 86. Every July since 1942, when the official recording station for
There is one good byproduct from this cool summer. There is less of a threat of the
If it feels like this has been an unusually cool July so far, you are right. This is the coolest July in 25 years, at least so far. That will change though by Friday. Watch for the return of some heat and humidity for the end of the week. We could hit 90 in a few southern suburbs Friday. Along with the return of heat and humidity comes an increased risk for severe weather. The Storm Prediction Center has outlook northern
