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.

As we alluded to in the post earlier this morning, the weather pattern is beginning to get more active. As “seasoned” Hoosiers know, this is only the beginning of a rather “vamped up” weather period through the next 7-8 months around these parts. Yes, the lazy, hazy days of summer in the weather office are over. Speaking of the weather office, I’m continuing to get settled into the new “home base” office. As I get settled, more and more products will begin to hit the site to help keep central Indiana Hoosiers abreast of what lies ahead in the weather department.
As we look at the upcoming week, we’ll note the trough and dominant northwesterly flow of the weekend begins to “relax” by mid week and weak ridging takes it’s place. This will lead to a warmer and more muggy (though nothing close to as oppressive as last week) feel to the air by mid week. We also note another dip in the jet by next weekend. While details still have to be ironed out, there’s a good shot of rain due in here by week’s end along with another cool down by next weekend. I also want to point out the re-curving typhoon out in the western Pacific. This is in association with upper level ridge placement in the Pacific Ocean and we can actually use this tool to help us forecast weather here on the “home front” in the 6-10 day period. That would bring us roughly to 09.25.13 (give or take a couple of days) and would line up nicely with the cool end of the month we’ve been talking about for some time. Recall that we’ve said we anticipate a warmer than normal month to continue (in the overall pattern sense) up until the last 5-7 days of the month. Does this help set the stage for a colder than average October ahead? Stay tuned…
Here’s a look at our precipitation outlook, compiled this afternoon using a variety of short and mid range forecast models.
Watch how the troughs (cooler air) and ridging (warmer air) correlate with the temperature pattern in our official forecast (posted earlier this morning).
