Flash flooding possible for Southern Wisconsin and Northern Illinois early Tuesday

untitledA complex of heavy thunderstorms is developing in Southwestern Wisconsin and far Northwestern Illinois as of 11:15pm. These storms will continue to develop eastward along the Stateline through 2am. With weak steering wind aloft, the storms will remain fairly stationary, allowing them to produce 1-2 inches of rainfall per hour. Remember, never drive across a flooded roadway and use extreme caution in low-lying areas along creeks and small streams which could undermine roadway surfaces.

Highlighted on this map above (in green) are areas most prone to flash flooding through the mid-morning hours. Flash Flood Watches remain in place! -Eric

It’s Raining, It’s Pouring!

1It has been quite the soggy period for us here across the Stateline. Wave after wave of heavy rain has tracked through the area since Friday morning, and we aren’t close to being done yet! Friday morning through early this morning we have already racked up 3.91″ of rain NOT including the rain we have received since midnight. When we add in those totals, and the additional rain that we will receive this afternoon and tonight, we could close in on 5″ in 4 days! If you’re itching for a return to sunshine and calmer weather, you’ll have to wait until late week, but the good news is that all weekend could remain mostly sunny and dry. -Greg

More thunderboomers coming

temp temp2Thunderstorms have been developing this evening in South-Central Iowa with a few reports of some hail and gusty wind. These storms will develop into an MCS (Mesoscale Convective System) after midnight. Steering wind will take these northeast through 1am and then due east through the morning hours. The timing puts the storms along the Mississippi between midnight and 2am and through the Rockford area shortly before sunrise. Heavy rainfall will be a distinct possibility with high levels of precipitable water in the atmosphere. Severe weather will be limited, but a few of the strongest storms could produce brief, large hail and some gusty wind.

Heavy rain will be possible with any thunderstorm complexes straight through Wednesday. River levels will go up near flood stage this week so please postpone any recreation!

A front will bring an end to our stormy pattern on Wednesday evening. Quieter and seasonable as we look into the weekend. -Eric

Severe Thunderstorm Warning

2UPDATE: 10:42am: A Severe Thunderstorm Warning is in effect for Winnebago and Boone County until 11:15am, as well as Ogle and DeKalb County until 11:30am as a thunderstorm capable of producing wind gusts in excess of 60mph tracks to the east south east.

UPDATE 9:13am: Severe Thunderstorm Warning has been CANCELLED for Green County, WI. Strong wind and heavy rainfall can still be expect though. This system is weakening slightly as it enters out area, but again heavy rain and damaging wind with gusts upward of 60 mph are possible.

 

A severe thunderstorm watch has been issued for all of Northern Illinois. A line of heavy to severe thunderstorms is closing in on the Stateline. Within the next few hours a line of thunderstorms capable of producing up to quarter size hail and damaging wind will make it to the Stateline, however the best chance for severe activity will be in Green, Jo Daviess and Stephenson County. The track of the storm could bring severe weather further east and we will monitor the system as it approaches and keep you updated! -Greg

Severe Stays Away

CaptureTomorrow we begin a significant warm up, we ramp up the humidity and introduce a chance for some weekend thunderstorms. The good news for us is that the strongest of these storms should stay well to our north and west. A slight risk for severe weather has been issued for parts of the plains states, Minnesota and Central to Northern Wisconsin. We aren’t included in that area due to the postioning of a cold front off to the west and the jetstream to our north with will help guide the more intense storms away from our area. The activity we see we be in clusters and most of our weekend will end up dry, however a few of the isolated storms could be on the heavier side. -Greg 1

Stormy and steamy weekend ahead

CaptureAs a dome of hot air descends on the Upper Midwest, I’m afraid we’ll be hoping for some cooling showers for relief this weekend. Here’s the set up as the jet stream rides high around Lake Superior. This will allow the warm air to move into the Great Lakes. If we didn’t have any chances for storms, we’d be solidly in the 90s. However, we will have some boomers riding the ridge of high pressure to our north. While it won’t rain the entire weekend, there will be a few hours of rain and thunder for the weekend. Capture2The way I look at it, we’ve got two hours of each weekend day/night with rain which leaves us with plenty of time to enjoy the great outdoors. -Eric

Humidity on the Rise

Yesterday was one of the most gorgeous days we have seen in quite some time. We had ample sunshine, comfortably cool temperatures, low humidity and just the slightest breeze. Today we can expect much of the same, however, by Friday the temperatures will be on the rise and so will the dew points. Humidity will begin to rise on Friday as dew point temps climb into the 70s. Those high dew points will stay in the 70s during the afternoon for the entire weekend meaning that our old friend the heat index will be in play and could top out as high as the upper 90s! We do have the chance to see a few scattered storms Friday-Sunday which would be life savers by keeping our actual temperatures in the 80s and our of the 90s. Either way, its going to be warm and muggy this weekend! -Greg Capture
