UPDATE: We have a Flash Flood Warning still for Jo Daviess and Stephenson Counties until 9:45am. Winnebago and Boone Counties were under a Flash Flood Warning until 8am, that has since expired but the National Weather Service still has Winnebago and Boone Counties under a Flood Warning until 11am. Northern Dekalb County and Northern Ogle County were both added to a Flash Flood Warning until 10:00am. Southern Ogle County, Northeastern Lee, and Central DeKalb Counties now included in a Flash Flood Warning until 11am. It is possible that we see some of these extended due to the heavy rain still moving through the area and that is expected through Monday morning before becoming scattered through the afternoon and isolated early Monday evening. This is a very dangerous and life-threatening situation where you need to stay home and off the roads if you can. If encountering flooding immediately get to higher ground.
As far as totals over the last 12 hours as of 8am Monday morning, Freeport is already exceeding 7 inches and that does not include much of the heavy rain that caused some serious flooding yesterday. We are hearing of reports of significant flooding in the City of Freeport and officials are advising to stay home. The National Weather Service says this is quote, “A life-threatening situation”. Areas such as the west side of Rockford received 4 inches. The Rochelle area has seen reports up to roughly 2 inches of rain and places southeast of Janesville measured about 0.3″ of rainfall over the last 12 hours.
Similar yet again Monday morning, we are watching a line of very heavy showers and storms move through the area. Rain will continue to obscure visibility out there through Monday morning and through the early afternoon so be careful while traveling.
Showers are expected to become more isolated by the afternoon but there will be a lot of heavy slow moving rain Monday morning. Rainfall rates are currently up to about 1+ inches of rain per hour.
Stateline areas are waking up to temperatures in the mid to upper 70s in most areas early Monday morning so it is a mild and a muggy start to the day.
Monday afternoon daytime highs will be in the upper 70s. Overnight Monday, temperatures will be a little bit cooler and come down to a comfy level right near the 60 degree mark, much different from the last few evenings. Winds will be between 20-25mph again Monday so similar to what we have had over the last few days. Monday night winds will calm down a little bit more with gusts only reaching 15mph. Tuesday winds are expected to calm down.
We keep a small chance of rain in the forecast Tuesday and then again Thursday. Wednesday will be the best day to get outside to enjoy the sunshine and better temperatures. Temperatures will only be in the upper 70s/lower 80s most days this week so a change from the warmer weather we had out there last week.
