An upcoming shot of winter
This will be another active weather week, from the 50s, wind, and rain coming tomorrow for Election Day, to the 30s by this weekend. We'll most likely have our first taste of winter late this week and into the weekend, whether we're ready or not. Not only will see highs only in the 30s for multiple days, but the cooler-than-normal weather could easily continue throughout next week as well. And the Climate Prediction Center agrees as well.
In fact, we have a greater than 60 percent chance of hanging onto the cold weather through the 19th, which is fairly good confidence this far out. During this cold snap, highs will be falling from near average in the next few days to 10, 15, and even 20 degrees below average. So, be prepared to switch those jackets out for the coats this weekend.
It'll be a sharp drop from Tuesday to Wednesday and it'll only continue to cool down as we're expecting a steady stream of cold, Canadian air to easily flow down through Michiana after this strong low moves through Tuesday. That cooling will be able to drop temps for the majority of the atmosphere from cloud level to the ground, so any precip that's possible during the late week and weekend, could easily fall as a wintry mix and/or snow. Here's a look at the precip chances.
They're low, but it's still something to be aware of. Best window looks to be Thursday night into Sunday. Lake effect rain/snow showers, switching to all snow overnight is possible Thursday into Friday and maybe Friday into early Saturday, even Sunday too.
It's too early to talk about accumulations, but early indications point to very small amounts. After all, ground temperatures are above freezing so anything that sticks will stick to the grass. And early in the snow season, we'll typically see the snow stick best during the overnight hours.
