Today's Daily Digit
A somewhat subjective rating of the
day's weather, on a scale of 0 to 10.


A cooler morning may offset a slightly hotter, but still not humid afternoon.

Today: Partly to mostly sunny. 20% chance of p.m. storms. 89-92. | Tonight: Partly cloudy. 70-74. | Tomorrow: Partly to mostly sunny. 20% chance of evening storms. 90-93. | A Look Ahead | Get Express Forecast by E-mail


We were finally able to remove ourselves from the heat as yesterday saw the first day below 90-degrees in about two weeks. Unfortunately, we have a second course of humid heat here in the next few days, but do not expect as much of a scalding. A cold front arriving just in time for Friday and the weekend promises to be stronger than our last one, which means an entire weekend of 80s and low humidity. Bon Appetit!

Today (Tuesday): High pressure overhead will do everything it can to keep our day mostly sunny and mostly pleasant across our area. Some humidity and cloud cover just to our south could try to creep into the southern sections where the majority of the slight 20% risk of showers or storms will be found this afternoon. Yes, humidity will be slightly higher than yesterday, but still comfortable as temperatures reach their peak into the upper 80s to low 90s. Light and variable winds.Confidence: Medium

Probability: 20%
Coverage: Widely Scattered
Most likely timing: 4 p.m. to 10 p.m.

Tonight: A continued 20% chance of mainly evening storms predominantly south and west of the city is seen, but otherwise, we can expect partly cloudy conditions with lows in the low-to-mid 70s. Light winds should mostly come from the south. Confidence: Medium

Keep reading for the forecast through the weekend...

Tomorrow (Wednesday): Those winds from the south will act like a slow drip bringing a gradual build of humidity back into the area. We will also see those temperatures slightly increase. Highs should be in the low-to-maybe-mid 90s. That humidity increase means we cannot rule out a thunderstorm, so we need to keep a 30% chance for storms, especially towards the evening. Confidence: Low-Medium

Tomorrow Night: A 30% chance of storms is included again with partly cloudy skies and warmer overnight temperatures in the mid-to-upper 70s. Confidence: Low-Medium


Thursday should be our most humid day of the week and it should also be our hottest. However, there is a risk that significant cloud cover and scattered storms/showers could fight the hotter daytime expectations. For now, we will favor highs in the low-to-mid 90s, but will watch the precipitation timing closely. The probability that you will see a thunderstorm is up around 60%. Winds should be from the southwest until the cold front passes in the evening and winds shift to come from the north or northwest. Partly cloudy skies on Thursday night with lows back down in the low 70s. Confidence: Low

Friday looks to be a spectacular sunny day with high pressure, low humidity, and high temperatures ONLY in the mid-to-upper 80s. Winds could be breezy from the north and northwest. Friday night should be a perfect cool and comfortable evening to see a ballgame (and yours truly will be enjoying the evening watching the Nats brave the Phils). Confidence: Medium

The weekend is bonus weather time with mid-to-upper 80s for highs and lows in the upper 60s to low 70s along with lower humidity. Saturday appears to be the best day right now with mostly sunny skies. Sunday looks partly cloudy, but we introduce the risk for a disturbance to pass through the area with showers (let's say a 30% chance for now). I'm currently skeptical of the threat and believe this weekend will be a much nicer alternative to our blowtorch situation from last weekend. Confidence: Low-Medium

I guess I don't understand why today is rated an "8". Temps in the 90s, moderate humidity, and chances of evening T-storms doesn't sound like a great day to me. Sure it's better than what we've had of late, but I thought the daily digit represented a score relative to all days not just recent days.
Also, please, please clean up the website - it's getting slower and slower as more and more stuff weighs it down. Seriously, I'm starting to avoid it just because I know it'll take a while to load. And that's true of the entire WP site. Compared to the NYT or the Guardian site (the other 2 good news sites) the WP site is very SLOOOOOOW.

Have you been outside yet this morning? I just finished walking the dog and it is downright beautiful out there. Compared to the humid, smoggy mornings last weekend, the morning by itself is probably a 9 or 10. But the slight increase in heat this afternoon is probably a 6. So I did an average! Take a walk outside and perhaps you may reconsider too. Otherwise, I cannot speak to your technical concerns, but it will be passed along. Thanks.

Irrespective of what we say the digit is, note it's subjective, and you can vote on it yourself.

I removed some of the apps from the page which may have been impacting load time. We realize our page sometimes can get bogged down and we're going to try to work towards speeding it up.

I agree that CWG page load time had gotten slow; glad it's being rectified.

Yes - the slowness is noticeable lately!

Jason: thanks for addressing the website issues. I think you guys have great content on the site, I just hate to see it go to waste due to poor design or overloaded with too many things.
It's certainly true that your daily digit is subjective and therefore you can make it what you want, and yes it was nice out there at 8am, but the description of how the rest of the day played out just didn't seem to jive with an "8".

pardon the interruption, but, i found this shocking:

"June 2010 was the fourth consecutive warmest month on record (March, April, and May 2010 were also the warmest on record). This was the 304th consecutive month with a global temperature above the 20th century average. The last month with below-average temperature was February 1985."


omg! 25 YEARS since a below average month! wow...

carry on.

Thunderstorms this afternoon/evening???...I detect a couple or three warning signs:

(1) Prominent, though scattered, altocumulus castellanus clouds, some looking a bit like incipient high-based thunderstorms, which I can remember from my Upper Midwest experience. I can also feel a bit of humidity in the air.

BTW, maybe we're feeling the global warming. Mr. Q doesn't seem to be posting these days with skeptical views on climate change. The world has been warming, even during January and February, while we were in a cooler airstream thanks to the Greenland block. Much of the rest of the world was warming at this time. This summer, South America seems to have gotten the cold outbreak.

Finally: my take on CWG website issues. Much of what I've experienced seems to relate to advertising add-on apps inserted by the Post. Often this "spam" takes over the website at first [like, you've gotta see the commercial before you get to see what you want].

(2) Dance tonight at the Clarendon Ballroom...the "much-needed rain" crowd LOVES to catch El Bombo off guard!

(3) Channel 9's OCM--Howard Bernstein,I believe today--is mentioning the threat of isolated thunderstorms, despite no expected major action until Thursday afternoon. [Perhaps Bonnie's remnant moisture has decided to make a left turn up the Middle Atlantic Coast.]

WGN Update...Snow lovers will get some encouragement. According to Tom Skilling, four out of five winters following summers such as Chicago has experienced thus far this year have been followed by winters COLDER than normal...and cold air in Chicago more often than not travels eastward to the mid-Atlantic area! One word of caution involves the fact that we may be getting a La Nina winter--typically such winters are like that of 2008/2009--colder but DRIER than normal. Much of our snow could be in the form of flurries as we experienced two years ago.
