Zionsville, IN Our pleasant early fall weather will continue as we put a wrap on the work week.  We’ll note increasingly cloudy skies late Saturday and this is a sign of changes to come for the second half of the weekend.

Beautiful Close To The Week:  After a few days in a row of “severe clear” it’s only fitting that we finish the week with a clear sky. High pressure will remain in firm control of our weather and temperatures will run a solid 6-8 degrees above normal, as we top out Friday afternoon around the 80 degree mark.

Approaching Storm System: While an approaching storm system will dampen our weekend plans Sunday (hey, not a bad day to be indoors watching the Colts game), Saturday will start sunny before clouds increase during the afternoon and evening hours. Temperatures will remain much warmer than average. As we look more closely at Sunday’s forecast, we note forecast models struggling over the past couple of days. In fact, today the European model tried to stall the front near the region, continuing a light rain threat into early next week. We think this is unlikely, but we’ll keep a close eye on model data over the next couple days.  Regardless, showers will arrive Sunday morning with a potential clap of thunder. Today’s model data has been a little more “generous” on rainfall amounts with perhaps as much as one half inch (on average) falling across a landscape needing rainfall badly.

Briefly Cooler: As the front moves east of the region a cooler air mass will be allowed to take control. We’re not talking about any sort of unseasonable chill this go around, but temperatures will feel very much like where we should be for late September Monday.

Moderating Again: A big upper ridge will build into the Ohio Valley and Mid West by the middle and latter portion of next week and this will lead to a continuation of a dry and unseasonably warm pattern next week.
