All eyes are on a strong, late-summer cold front that is poised to move through the area Saturday. Earlier this week it looked like it may bring very heavy rain for over 36 hours, in addition to a chance of severe weather. However, the latest forecast model runs are suggesting rainfall to last roughly only 12 hours. In addition, instability and wind shear both look to remain on the low side. As a result, the severe weather threat looks quite limited at this time. That does not mean a stronger storm won't happen, but the threat is minimal. Rainfall does still have the potential to be heavy at times with a humid air mass expected to be in place immediately ahead of the front as it slides through. Temperatures will likely only top out in the 70's as a result of the enhanced cloudiness and expected rain. Once Saturday evening arrives, it looks like the bulk of any concentrated rain will be ending.
For morning and afternoon plans, it will be a good idea to have umbrellas or tents available. Any evening plans will likely be unaffected, which bodes well for the Mo Pitney concert set to begin at 7 PM at the Winnebago County Fair. After the rain comes to an end, cooler air will filter in with high temperatures in the lower 70's on Sunday and middle 70's on Monday.
