Beautiful & Chilly End to Work Week

What a wild Wednesday in the weather department! We saw warm temperatures, cold temperatures, windy conditions, rain, mist, a few peaks of sun, and plenty of cloud cover. In fact, our temperatures in Rockford fell from 67° shortly before noon to 48° at 8pm! That is nearly a 20-degree drop in just about eight hours. We can thank a powerful fall cold front for bringing in the colder air and rain showers. The good news is we didn't see a lot of rain, but it was around for a good portion of the day. Now we shift our attention to the west. That is where a dome of high pressure is located Wednesday evening. It will slide overhead Thursday night before moving east by Friday. That high will deliver very chilly conditions Wednesday night and Thursday night.

Temperatures each night will be in the middle and upper 30's. However, lower 30's are a real possibility in rural and outlying areas. A Frost Advisory is in effect Wednesday night, and one may be issued for Thursday night as well.
That advisory does not include Whiteside, Lee, DeKalb, or McHenry Counties. It is effective from 2am-9am Thursday morning. And, with the threat of frost in the forecast, it's important to remember to cover up or bring inside those tender plants. The area of high pressure won't only bring cooler air into the Stateline, but it will give way to clear skies both Thursday and Friday. That means abundant sunshine each afternoon, which will help make the cooler temperatures feel a little warmer.
For Thursday, sunshine will only warm us into the middle 50's, but a light wind will make it feel a little warmer. Friday we can expect to see the same thing, but temperatures will be even warmer in the middle 60's as winds begin to strengthen late in the day out of the southwest. The sunshine and cooler temperatures don't last, though. The 70's return by the weekend, as do multiple chances of rain and thunderstorms. So if you want to get any outdoor work done, use Thursday and Friday!
