Holiday Weekend and Next Week

It's been a gray work week with the storms and rain, but the start of the weekend will actually be pretty nice!  Partly cloudy skies and temperatures in the low 80°s are expected for tomorrow, but it'll feel a little humid as dew point temperatures will be in the mid 60°s.

A cold front is beginning to move into the Stateline, and will progress slowly through our area during the rest of the day.  This is because there's an upper level trough digging to the south, which will slow the movement of the low pressure system and the cold front.  This will keep our thunderstorm/rain chance with us between now and this evening.  Stronger storms will stick down to the south in central Illinois, where the front will be stronger.  However, there is a slight chance for some hail in our southern counties: southern portion of Dekalb county, Lee county, and Whiteside counties.  Other than that, only heavy rain is expected from these storms.

That cold front will move out around 10pm, where a high pressure system will move in from the west to give us clear skies for the overnight.  That high will stick around for Saturday, giving us a break from the storms and rain.  Another low will form west of us on Sunday, pulling in more warmth and moisture, which will bring back our storm chance.  That low will linger through most of next week due to an upper level low being cut off from the jet stream.  This will keep our storm chance for most of next week, and unfortunately the Fourth of July is included in this.
