Father's Day Forecast

Here's a first look at your Father's Day forecast: The high temperature is forecast to be in the low to mid-70's with some very light wind. Mostly cloudy skies will be overhead the majority of the day with the chance for some scattered showers and possibly an isolated thunderstorm particularly in the morning and afternoon. However, conditions should dry out by the early evening. Tune into Eyewitness News as we will continue to update our forecasts!

Blustery Friday Afternoon

Just like yesterday's set up, a tight pressure gradient will be responsible for the windy weather this afternoon. During the afternoon yesterday, a few spots across the viewing area recorded wind gusts up near 30 mph. As we head into our Friday afternoon, two weather systems will cause even stronger wind gusts across the viewing area. Here is what we mean.
 
As a low pressure located over Minnesota inches closer to the strong high pressure system that is over the Tennessee Valley, the pressure gradient in between the two will straighten and tighten up resulting in some gusty winds. When it comes to Meteorology, the stronger the pressure gradient is, the strong the wind gusts will be.

And since we are smack dab right in the middle of both systems, southwesterly winds this afternoon could gust as high as 40 MPH at times. It would be a good idea to grab any loose objects in your yard or bring your trash cans inside. With winds this strong, they could end up in your neighbors yard, or even down the street. This could also make driving on east-to-west oriented roads a bit difficult for high-profile vehicles and semi-trailers.

Despite the windy conditions this afternoon, clouds will gradually increase. There is a slight chance for an isolated shower later this evening, but models still suggest much of the afternoon remains dry. After reaching our high of 74° near the start of the event, temperatures should slowly drop through the low 70s by the end. So if your Friday evening plans take you to City Market or Old Settlers Days, you’ll be good to go by leaving the umbrella at home.

Rain Returns Wednesday Evening

Scattered showers will continue across northern Illinois and southern Wisconsin Wednesday evening, but with limited instability overhead the threat for thunder will remain low.  The showers are forming ahead of a cold front currently located from Janesville down to Rochelle. There are a few additional showers and isolated storms west of the front over Iowa that will move through later this evening.

Dry air moving in behind the front will help turn skies partly cloudy by Thursday morning. Winds will increase from the Northwest, gusting near 30 mph throughout the day Thursday. An isolated shower or two can't be ruled out late Thursday afternoon southeast of Rockford, but most are expected to remain dry.

Record Heat Builds Out West While Temperatures Tumble Further East

Record heat has been occurring up and down the West Coast the past couple of days while temperatures cool further East across the Great Lakes and Northeast.

A strong ridge of high pressure has developed along the west coast bringing triple digit heat from California to Oregon.  Heat Advisories and Excessive Heat Warnings remain in place from California to Arizona. 

The blocking pattern that has been in place will begin to break down by the end of the week and weekend with the flow of the jet stream becoming more zonal, or west to east.  This will allow fast moving storm systems to move across the middle the country with several chances for showers and thunderstorms, with the first arriving Friday night into Saturday.  Rain chances return through the weekend and into next week with possibly another round of soggy and heavy rainfall possible.

Windy & Cooler Start

High temperatures the last 6 days here in Rockford have climbed into the low 80s.  Granted, the stretch did start with some rainfall on Tuesday and Wednesday. But after that, mother nature brought our the sun and kept thing warm and dry heading into the weekend. Unfortunately, the streak comes to an end today. A cold front has slid through Northern Illinois this morning, ushering in a slightly cooler air mass and gusty northwesterly flow.

The windy conditions starting off the new week will stick around through the rest of our Monday. Gusts through the morning and afternoon will climb to between 30 and 40 MPH at times. All of the windy weather is thanks to a cold front that passed through Northern Illinois. That same cold and a strengthening high pressure system over the Midwest is causing a tight pressure gradient at the surface. Wind gusts right now in a few spots are at or over 30 mph.

Aside of the windy conditions today, today will also feature mainly sunny skies and seasonably cool temperatures. Highs this afternoon will be in the low 70s. As that cold front continues to move farther away, winds will begin to subside, especially this evening. High pressure will slide just south of the region, which will lead mostly clear skies and light wind tonight. So if you are into stargazing, Jupiter and Saturn will be pretty close to the earth! Its going to be a beautiful night for that tonight.

Stretch of Warm Weather Continues

After a rather cool end to May and start to June when we struggled to reach the 80 degree mark, today (Friday) marks the fourth day in a row in the 80's for Rockford.
Saturday's high temperature is forecast to be 80 degrees exactly but unfortunately that should be the end of our 80 degree streak as we expect a slight cool down to begin on Sunday and continue on through the week. Although it may not be as warm, we should have at least a few dry days in the week ahead. Tune into Eyewitness News for more!

Severe Weather Threat for Saturday


All of northern Illinois including portions of south central and southeast Wisconsin are under a slight risk for severe weather today.
Strong to severe thunderstorms will begin to develop in southern Wisconsin by mid-afternoon and continue to form and push south until the early evening hours. The highest probability for severe storms will occur between 4PM and 6PM.
These storms should be fairly scattered meaning any given town in the Stateline Area should see a few separate rounds of heavy downpours and high winds rather than it all occurring at once. The primary threat with these storms are heavy rain and high winds although some sizable hail is very possible as well.
Stay tuned to our social media and to our newscasts as we continue to update you on these thunderstorms.
