FORECAST IN DETAIL
After a mostly calm and quite warm September, we have been seemingly catapulted into a much more volatile, transitional weather situation. From our previous dryness standpoint, this is a good thing as we'll see frequent chances of precipitation. But from a daily outdoor planning angle, this creates complexity that challenges our confidence at times. In the coming days, we'll see the weather change quickly from one half of the day to the next.
Today (Tuesday): Look out for some early morning heavy showers or even some storms. The biggest downpours should be running through the western suburbs in the early hours into the eastern suburbs by mid-morning. Skies should break a bit around midday and then clear in the mid-to-late afternoon, boosting afternoon high temperatures into the low 80s. Light winds come from the west by afternoon. Confidence: Low-Medium
Tonight: Mostly clear skies allow for cooler low temperatures. Low 50s are expected in the suburbs with around 60 in the city. Light winds. Confidence: Medium

Tomorrow (Wednesday): Mixed skies in the morning with some sunshine, but clouds increase again in the afternoon, hampering high temperatures (low-to-mid 70s). Some showers could (30% chance) sneak back into the area by the early to middle evening rush hour. Confidence: Low-to-medium.
Tomorrow Night: Depending on the track of storm system originating in the Caribbean, rain probably (50-60% chance) moves back into the area overnight. Some of the possible showers and embedded thunderstorms may turn heavy late at night into the morning, especially east of the city. Lows range in the upper 50s to low 60s. Confidence: Low-Medium
Thursday looks complicated as yet more tropical moisture streams from south to north through the Eastern U.S. Heavy showers and storms are possible, but there's a high degree of uncertainty about the storm track and where the heaviest precipitation will occur. Overall, not a pleasant day with cloudy skies and muggy temperatures in the 70s. More showers are possible Thursday night with lows in the 60s. Likelihood of precipitation Thursday and Thursday night is around 70%. Confidence: Low
Friday could be peppered with morning showers (40% chance), but there are indications that drier weather along with clearing skies could arrive by the afternoon to set the stage for a nicer weekend. Highs again are in the 70s. Confidence: Low
The weekend weather delivers a big taste of October as temperatures reach their coolest levels of the autumn. Highs should be in the 60s and lows in the 40s. While the weekend should be mostly dry, there is some degree of uncertainty as a lot of cool air in the upper levels creates instability and variable cloud cover. This could trigger some light afternoon showers, but nothing like the tropical rains of this week. Confidence: Low-Medium
