Storms Fire This Evening; Early October Blow Torch…
Updated 09.26.23 @ 7a
A closed upper low will pivot across the Ohio Valley over the next couple days. Our quiet start this morning will give way to “bumpy” times by evening. We expect scattered, but strong to severe storms to fire up after 5p. A couple of these could produce hail/ wind and we can’t rule out a quick spin up tornado with this setup.
The Storm Prediction Center highlights most of the area in a “marginal” risk of severe weather today, and I wouldn’t be surprised if a portion of this area (particularly western and central IN) is upgraded to a “slight” risk at some point.
Storms should become most widespread just before sunset and continue into the overnight hours.
As we transition into Wednesday, morning convection will likely still linger before greatest concentration of rain and storms pivots to eastern and southeastern parts of the state by afternoon.
By the time all is said and done, many central Indiana rain gauges can expect to pick up between 0.50” and 0.75” of rain but there will be a few lucky folks that accumulate much more (type setup capable of 1”-2”+ in localized areas).
As we get set to rumble into the weekend, drier air will return and plentiful sunshine is expected. We still expect an unseasonably warm open to October with an extended stretch of days in the lower to middle 80s- good for 10° to 15° above the norm.

Cruising Into A Warm Close To September/ Open To October; Mid-Month Changes Brewing?
Updated 09.23.23 @ 7:50a
Dry conditions will prevail through 99.9% of the weekend and for most, 100% of the time. A few very light showers may sneak into western counties Sunday night, but light is the key word. With such a dry airmass in place, most of this activity is expected to arrive in a weakening state.
The temperature pattern is “easy peasy” this week as unseasonably mild temperatures dominate. An extended stretch of highs around 80° can be expected in the week ahead.
An upper low will pivot out of the Mid West and through the Ohio Valley midweek. This will deliver more in the way of unsettled weather for our neck of the woods, but we’re still not overly excited about rain chances.
Scattered showers will build into the picture Wednesday and Thursday, courtesy of the aforementioned upper low pressure system. From this distance, rainfall totals are expected to be light (mostly in the 0.10″ to 0.25″ range) and certainly not uniform in nature.
As we head into next weekend and the beginning of October (can you believe it?!), the ridge will expand overhead and lead to a return of quiet and milder times.
Down the road, as mentioned in this week’s long range report, I still would be very suspicious of the warm paint blob shown on most modeling towards mid-October. The thinking here is the negative EPO and positive PNA will begin to do work, leading to a fairly sizable shift in the ‘mean’ pattern…
