A Major Pattern Change Ahead

Good Thursday, folks. As we head into the closing days of September, the overall weather pattern is threatening to take a walk on the wild side. The setup will take us from a very warm one to a very cool, if not downright chilly one. With that transition will come plenty of rain and storms. Unfortunately, we could be looking at too much rain at times.

Let’s start with the summer steam of today. Temps and humidity levels are both running high and that will lead to isolated showers and storms going back up…

A cold front approaches the region from the northwest late Friday, touching off showers and thunderstorms. Some of the storms may be strong or locally severe. Here’s the Severe Weather Outlook from the Storm Prediction Center…

That boundary hangs around through the weekend with waves of showers and a few thunderstorms showing up. While it won’t rain the entire weekend, it’s going to be difficult to pinpoint when those waves roll in and the dry hours between them. One thing is for sure… Temps will be much cooler. Some areas may stay deep into the 60s for highs.

Some serious chill invades the middle of the country early next week and will move in here by the end of the week. That transition is likely to produce a lot of rain across our region. A southwest to northeast flow will setup shop, leading to the potential for way too much rain. Take a look at the model rain numbers through next week…

A significant fall cold front moves through later Wednesday and Thursday, bringing a dramatic temperature drop.

Another front sweeps in behind that by Friday and Saturday with even colder air. Highs behind this front may stay in the 50s for a few days with lows that can drop into the 30s…

My “early season frost potential” thoughts from a few weeks ago are in the ballgame, at least. 😉

Better yet, go ahead and get your chili ingredients chili shopping done. I smell a full blown alert cooking.

Early season flake potential continues to show up VERY far south for the end of September and first few days of November.

Have a great Thursday and take care.
