Shower chances move in Thursday and linger through the weekend

Good Wednesday evening. I'm Chief Meteorologist Emily Walls. We had a stunning day today. Temperatures ended up topping out in the upper 70s across most of the area, and that's putting us about 20 degrees above average for this time of the year because Chicago's average high temperature for today's date, October 28th, is 57 degrees. And today we topped out again, mid to upper 70s across most of the area. Here's a look at the satellite and radars. So things are quiet now. We have clear skies overhead that will change overnight. We'll see increasing cloud cover. because of a cold front that is off to our west and we're starting to see some showers and thunderstorms firing up right along that frontal boundary but you'll notice here as it gets a little bit closer to us tomorrow morning a lot of that's going to fizzle out so we do have a chance of seeing some scattered showers maybe a rumble of thunder tomorrow but the overall coverage of the rain that's likely to develop should be fairly minimal I'm looking at about a 40% chance of rain tomorrow and it's just going to be from mid to late morning through about mid-afternoon after that we're really going to begin to dry things out we have high pressure building back in and if you think back to the beginning of the week when we were advertising the seven-day forecast there was a string of 70s for the end of the week right on through Halloween but based on the placement of this high pressure system here that's why we've had to lower those high temperatures so notice the clockwise wind flow around that high based on the placement of that we're going to be picking up east to east northeasterly winds on Friday so temperatures are going to be running cooler because we're getting that flow coming right in off of Lake Michigan that's why temperatures have been lowered to the lower 60s for your highs now on Friday but we will have plenty of sunshine to get the day started then we're going to be going back to mostly cloudy conditions couple stray showers possible during the day on Friday a better chance exists at night and then that's going to linger into the first half of the day on Halloween for tonight 59 degrees we'll have south-southwesterly winds, 10 to 20 miles per hour. 7-day forecast tomorrow, showers, couple thunderstorms, nothing severe, 67 degrees for your high. Friday is going to become mostly cloudy, a high of 61 degrees. Saturday for Halloween, the first half of the day, we'll see the chance of showers. But I do think that we're likely going to be drying things out in time for the trick-or-treaters. There may be an isolated shower still lingering around, but I think most of the area is likely just going to be partly to mostly cloudy by trick-or-treating time. Then on Sunday and Monday, we have another chance for scattered showers. Best chance of rain in the seven days actually coming our way on Election Day. We have a good chance of rain on and off through the day on Tuesday. High temperatures are going to be in the mid 60s.
