ROCKFORD (WREX) – Patchy areas of dense fog may slow you down this morning, but afternoon storms may have you reaching for the umbrella.
Visibility in portions of Lee and Whiteside Counties have been below 1/4 of a mile at times, but as the morning progresses, fog should continue to taper off. As has been the story over the last few mornings, if you happen to run into fog on your drive into work this morning, just turn on the low beams and give yourself increased distance between cars.
Foggy conditions will give way to mostly cloudy skies through the morning. While a stray shower cannot entirely be ruled out of the forecast, it looks like most rain chances will hold off until later today. A low pressure centered over Wisconsin will slip southeast through the day and could provide the spark for additional rain and storm chances this afternoon. Severe threat looks to remain low today, but a gusty thunderstorm or two is possible.
Part of the reason severe weather isn’t expected relates to the lack of instability. Thunderstorms feed off of heat and humidity. While we have some humidity still sticking around, highs today will only climb into the upper 70’s under mostly cloudy skies. Some areas may crack 80° if clouds are able to clear enough, but a look at visible satellite shows how socked in the Stateline is with clouds.
A cold front will slide through, reinforcing the cooler temperatures for tomorrow afternoon. Highs will be nearly identical to today’s temperatures, with most of the area remaining below 80°. Chances for rain look to remain confined along and east of I-39. A lake breeze looks to set up and some indications are that it may try to creep into far eastern portions of Boone and DeKalb Counties.
Better rain and storm chances come late in the week, with highs slowly climbing through the low and mid 80’s by Sunday.
