Good evening, everyone, it is Wednesday, October 13. And here is the weather synopsis for the United States. And first, I want to say that if anyone's interested in hearing just a quick weather synopsis with the forecast for Chicago, you can go to my other podcasts, it's just called Quick weather synopsis. And you can hear that it's was made this morning, this is more of an in depth discussion. That's what's gonna be going on on this podcast right now. We have probably the most dynamic part of this weather or the the system that's creating the most significant weather over the largest part of this country is a deep low pressure system located in South North Dakota. barometric pressure is 29.2, it certainly is a deep low pressure and the storm system is moving in a unique path, it's moving directly north and is headed into Canada, Manitoba. The system is going to weakened slightly but remain a deep low pressure system, it's going to weaken to 29.3. And it's going to continue to move directly north. It's not moving northeast, north, north east, slightly northeast, but really, it's taking the most intense track possible to produce heavy snow. This is what the North Eastern a lot of times do. There's also a call flow which moves right up the Mississippi River. And when that happens in the winter time, that's when the heaviest snowfall occurs. So there's no question we have cities also that have responded to this their cities in Montana. But as of this morning, one city got 28 inches of snow, another one. That's somewhere in the 20s others in the upper teens, and I believe the snow is still falling with an additional eight to 12 inches expected in some spots, the names of those cities, you could look up, I had the names, but it's going to create too much of apsic in this podcasts going to create an interruption here, so I'm just gonna leave it at that. And we also that low pressure system is producing other hazards as well. As I mentioned this morning, as severe weather outbreak is also on the side of that system on the south east side is it usually is now originally the Storm Prediction Center put Chicago and a marginally

chance for severe weather about a 10% chance. But that line moved further west. Now here's what's happening over here, because there was something that changed the major variable that changed, which is very much no gear has tremendous connection to the Chicago weather. And it's the exact opposite of what happened this past Sunday. And I want to explain that as well, because that requires an explanation. And I'll tell you why it requires an explanation in just a minute. The low pressure system earlier today, that storm system had a lot of forcing to it and the storms were developing right along where the warm front and the cold front came together. And that also where there was a lot of forcing a lot of energy in the upper atmosphere producing thunderstorm development, lots of lightning report in Missouri and in Iowa, the thunderstorm development continued moving east and Northeast away from where the most intense forcing is away from the intense low pressure system. And therefore the thunderstorms gradually reduced the gradually weekend. And they continue to weaken. And that's why that's one reason why as it reaches Chicago, we may not even have too much thunder, although there probably will be a little bit of thunder. The other thing is that it's going to be the system is moving much slower than originally thought both the warm front is moving slower and the cold front and the warm front, the warm air isn't going to get here until tonight. And then the cold front comes tonight. So the whole system is arriving in the middle of the night. The middle of the night is not an ideal time for thunderstorm development. Nonetheless, there could be thunderstorms in our area here in Illinois. And as you go further east, though, the chances for storms kind of decrease. Except it's already moving so
