Cooler Weather Settles in Behind Cold Front

Dew point temperatures so far this week have been on the uncomfortable side, but I am happy to say that relief has arrived. Showers and storms developed Wednesday afternoon as a cold front progressed through the area. Rockford (KRFD) actually ended up with .45" of rainfall. Lows this morning from Galena to Rochelle were able to fall into the middle to upper 50s. So despite a chilly start across the region, highs today should still be able to climb into the upper 70s. High pressure sitting to the northwest will allow the winds to flow out of the northeast which will help bring low humidity to the Stateline.


Now, this northeasterly flow at the surface will also be responsible for the development of a lake breeze boundary off of Lake Michigan this afternoon. As this lake breeze pushes inland, this could provide enough forcing for a pop up shower or two. So this is why we introduce a slight chance in the forecast, especially for our eastern counties. But mostly sunny skies will likely dominate most of our day today.
Overnight, lows will fall into the lower to middle 50s. Typically on average, the middle of September is when we see low temps in the low 50s. Friday morning will feature another quiet and crisp start with plenty of sunshine and those seasonably cool temperatures. The "taste of fall" continues through the day tomorrow as tomorrows high will be the coolest of the 7 day forecast. More sunshine and wind flow out of the northeast will once again allow temperatures to climb into the upper 70s. If you plan on making it out to City Market, it looks like the fabulous evening to go out and enjoy the festivities.

The upcoming weekend looks to keep the pleasant weather going. High temperatures slowly climb closer to 80°, but the cool mornings will allow you to keep the windows open overnight. High pressure anchored over the Midwest will slowly slide to the east. This allows for highs to reach into the lower 80s by the end of the weekend ahead of an approaching cold front that looks to slide through on Monday. We will also see an uptick the humidity as well going into the start of next week. That is why I continue to put this message out there; please take advantage of the weather that mother nature is giving us the next few day. You won't regret it!
