First Strong Cold Front Of The Season…
Our Friday is starting off with heavy rain and embedded thunder across western portions of the state.
It’ll still be a while before central Indiana gets in on the more concentrated, widespread rain. We think this arrives later this afternoon into the early evening hours. Most can expect to pick up between 0.20” and 0.40” across central parts of the state, but there will be a few locally heavier totals.
Before the rain arrives, a strong southerly wind ahead of the front will send temperatures to around 70°. Meanwhile, note temperatures at the same time already into the 40s across eastern IL.
The temperature crash will continue through the evening hours advancing east. By 7p, temperatures in and around Indianapolis and points west will be in the 40s. A gusty wind will result in “feels like” temperatures into the 30s.
The first freeze of the season is expected Saturday morning for many across central Indiana into western and northern portions of the state. We anticipate wind chill values to fall into the middle 20s.
Another reinforcing shot of chilly air is dialed up next week. More on this and other items a bit later…

Cool 6-10 Day Period Ahead, But Then What?
A strong cold front will sweep through the area tomorrow and help usher in the coolest air so far this autumn. This will set the tone, combined with the recurving WPAC typhoon, for a chilly upcoming 6-10 day period, but what lies beyond this period later in the month?
We turn to a couple of our more trusted teleconnections for advice.
Note the PNA “bobbing” up and down through the medium range period, with more of a negative look around the 20th. This argues for a milder stretch of weather around that time. (Further out, we’ll keep close eyes on the PNA to see if a more consistent positive signal develops as we inch closer to November).
The EPO pops strongly positive mid month which, too, argues for milder times, locally. That said, similar to the PNA above, the EPO is trending towards a scenario that would present colder times as we rumble towards November. We’ll monitor for consistency.
To no surprise, given the two primary teleconnection drivers above (remember these can change as the seasons evolve), we see the pattern set to turn milder just beyond Day 10. Note the strong agreement between the European, Canadian, and GFS ensemble data below.
