Aside from the patchy fog, today will see a repeat of the tranquil weather we experienced yesterday. If you’re preparing to walk out the door, don’t forget the sunglasses today. Despite the cloudy and foggy start, sunny skies will return later in the day. Today will feature a bit more cloud cover than what the Stateline experienced on Monday, but the dry stretch will continue. Most spots today will climb into the low 80s. Some areas of patchy fog could linger through the late morning hours before fully tapering off by this afternoon. Moisture will continue to stream in from the southeast today and tomorrow, before winds turn to the southwest as we head into the second half of the work week. This will help keep the humid weather around for a little while longer, meaning more foggy morning’s are possible this week.
Models continue to hint that we could experience some patchy fog during the morning commute tomorrow. Any fog that forms will quickly burn off to partly sunny skies which will allow our highs to climb into the low 80s once again. As high pressure continues to slide east, increasing moisture will get pulled into the Stateline. Thursday morning will bring the next chance for rain as our next system approaches. Rain chances will remain early on in the day, especially around the time when you are heading out the door. So having the rain gear on hand Thursday morning wouldn’t be a bad idea. Rain should begin to taper off by the early afternoon.
Along with Thursday’s early rain chances, the overall threat for severe weather is low. But heavy rain will be possible with any showers that do move through. Thursday will be the first of several unsettled days. Over the next five to seven days, widespread rainfall totals could be between .5″ to as much as 1.5″. As a reminder, flood warnings remain in effect for the Pecatonica and flood advisories remain in place along portions of the Rock River. Despite having a good stretch of dry weather, this newly added rainfall could cause river levels to rise leading to more flooding issues across the Stateline.
The unsettled weather pattern will continue into the weekend. A few things remain uncertain as we still have much of the week left. Models generally agree that Saturday features the best chance for rain with a passing cold front. This cold front giving us showers and storms this weekend will sweep through, bringing a return to more fall-like temperatures just in time for the official start of fall next Monday. As of a reminder, the Autumn Equinox occurs on Monday, September 23rd at 2:50 central time. Typically, our average highs are in the low 70s and our average lows end up in the upper 40s.
