Today: Cloudy with increasing shower chances. 56-60. | Tonight: Cloudy with showers ending. 39-45. | Tomorrow: Increasing sun. 60-65. | A Look Ahead | Get Express Forecast by E-mail


Temperatures take a 10-15 degree tumble today (compared to yesterday), so if you've been heading to work jacket-free of late, re-think that this morning. You also should bring along an umbrella, as damp flow from the east and a weak disturbance passing by combine to increase showers chances as the day goes on. While today's highs will be cooler than average, we should see above-normal levels again by Thursday and Friday with warm 70s. Over the weekend, we may dip back into the 60s with showers possible again Saturday.

Today (Tuesday): Cool flow from the east will generate dominating cloud cover with showers likely during the midday through afternoon. The rain should be mainly light, but combined with the clouds should be enough to limit highs to the mid-50s to near 60. Confidence: Medium

Tonight: Cloudy with showers likely before moving out by around 10 p.m. or so. Storm rainfall totals of up to around .25" are possible. Cool winds from the east will continue as temperatures drop by early morning down to the mid-40s in the city to near 40 in the far western to northwestern suburbs. Confidence: Medium

Tomorrow (Wednesday): We're back into the springtime groove tomorrow, with skies becoming partly to mostly sunny as drier air returns. High should max out in the comfortable 60-65 range. Confidence: Medium

Tomorrow Night: Skies will be clear with calm winds for most of the night as high pressure settles over the region. However, some warmer breezes from the west arriving toward morning should prevent temperatures from really tanking. Lows around 40 in the cooler suburbs to the mid-40s downtown. Confidence: Medium


Thursday, we'll benefit from a new westerly wind flow that should boost highs well into the 70s across the area. Look for copious sunshine to make this potentially the best day of the week. Partly cloudy skies and lows in the 40s to low 50s are anticipated Thursday night. Confidence: Medium-High

Friday should be another nice day until some clouds and showers threaten toward the evening (30% chance of showers). Highs are forecast to be in the 70s once again. Clouds and showers are possible Friday night (40% chance) with lows mainly in the 50s. Confidence: Medium

The weekend is not looking too great right now, but we might be able to salvage Sunday. A stalled low pressure and cool front over the area looks to give Saturday the brunt of the clouds and shower chances (40% chance as of now), but it may move far enough way to allow more sun on Sunday. Weekend highs should be in the 60s with lows in the 40s to low 50s. Confidence: Low-Medium

What is the timing looking like for rain on Saturday if it does rain?

Right now, the best chance would be the first half of Saturday, but that is subject to change, so we'll keep an eye on it.

Perfect weather for the garden, anyway. The weekend was a great for working in the garden. A little rain for the plants today, more sun on Thurs, and more rain on Friday. More gardening opportunities for at least part of the weekend. I like this better than shoveling snow!

Very cool and cloudy...the cloud formation looks like one of those high-based wavy/castellanus formations typical during warmer months in the Great Lakes area. It could relate to the fact that this airflow seems to be from that general region.

Has anyone downtown yet seen rain reach the ground? also, they are closing 14th street every 2 minutes. It's a surreal atmosphere with the Nuclear Summit. Center city should have just been given a 2-day holiday. ugh. Most security I've ever seen BY FAR.

I want to check in to see if y'all tend to post your forecast at 11am? Because that wasn't cool of you all posting the tidbit about it being cold and rainy since most of us do work 8-4pm... THEREFORE we didn't get the memo, namely your forecast, before we step out of our homes.

(and I went to work with no jacket nor any umbrella so you can imagine how freezing and wet I am after doing some office errands outside.)

no comments about the crazy weather we had downtown? strong winds and relatively heavy rain made for an interesting lunchtime stroll. didnt see the radar, but must been an isolated pocket or something. did anyone else notice

The forecast was posted at 5 am, and tweaked at 11 am... hence the 11 am time stamp. So the info about rain in the forecast has been up all day. Sorry for any confusion.
