For a change, the past (7) days has been generous to central Indiana from a precipitation perspective. As we’ll discuss, a new rain maker awaits this week.
A look at rainfall totals over the past 7 days, courtesy of weatherbell.com.
Officially, IND sits at 0.26″ above normal, month-to-date.
It’s also been an incredibly warm start to the month (IND is running 10° above normal, month-to-date) and that warm theme won’t change through the near-term.
An all-too-familiar pattern engulfs the country late week. This will showcase more “bonus” summer-like conditions, locally, that will include highs approaching 80° next weekend with a strong southerly flow in place. Additionally, early winter-like conditions will continue to impact the western high ground. The pattern definitely represents a Nina look.
The southeast ridge will provide more bonus summer-like conditions next weekend across the eastern half of the country.
In the shorter-term, a new rainmaker will move across the Ohio Valley Tuesday into Wednesday. This will spread showers and embedded thunder across the state Tuesday PM into Wednesday. In general, this storm system should deliver 0.50″ – 1″ of rain, but there will be locally heavier amounts.
Thereafter, dry times will settle in along with slightly cooler temperatures. Let’s remember it was only a few days ago where modeling suggested a “pop” of the season’s coldest air thus far. No longer is that the case, and while it will turn briefly cooler, temperatures will still remain above average.
A southerly air flow will return late week and help boost temperatures next weekend, along with continued dry times through the balance of the weekend. From this distance, our next storm system should arrive late Sunday or early Monday in the form of a cold front.
Looking longer-term, there are indications that colder conditions loom as we wrap up October and head into November and we’ll discuss this in more detail later this week…

After a cool, fall-like, weekend, we still expect a new surge of summer-like air to return next week as a strong (and expansive) ridge of high pressure “balloons” over the eastern half of the nation.
This will be enough to send temperatures into the 85° to 90° range by the early to middle of next week. To shed some perspective on that, our averages for early October include low temperatures in the upper 40s and highs in the upper 60s. For at least a couple of days next week, overnight lows will be much closer to where our afternoon highs should be this time of year.
There are differences on how modeling handles the evolution of things once past midweek. The European model has been jumping on a potential wet weather maker and much cooler trend in the medium term (late next week), but the GFS is having none of that- keeping us dry and hot. We’ll keep a close eye on things over the next couple of days and have a fresh 7-day soon!
Finally, we’re receiving many questions that are centered on whether or not the current overall warm pattern is an indication of what we can expect this winter. The simple and short answer to that question is an emphatic “no.” Transitional seasons are fickle, regardless of ENSO state. Throw in an emerging Nina and all sorts of additional “fun and games” ensue. With that said, there’s no direct correlation specifically between warm (or cold) patterns this time of year and the winter ahead. In fact, there’s been many instances where unseasonably warm Octobers give way to cold winters, and vice-versa.
More later! Make it a great Friday!

I.) Overnight rain and storms impacted central Indiana during the overnight. Some of the slow moving storms dumped a quick 2″ of rain in isolated areas, but most ended up…

I. A cold front will move across the state this evening. Ahead of the front, a warm and moist air mass will remain in place and the frontal boundary will serve as a “trigger” to ignite scattered to numerous showers and thunderstorms, especially this afternoon and evening. While widespread, uniform rains aren’t anticipated, a couple of strong storms and localized downpours will develop ahead of the front.
Scattered t-storms will impact the state today.
Eastern IN is included in a Slight Risk of severe weather this afternoon.
II. After a drier close to the work week (less humid, as well), an upper level disturbance will race across the Ohio Valley Saturday. This will provide enough lift to generate scattered showers and thunderstorms across the region, but all day rains won’t occur.
III. Ridging will return early next week and, though brief, a shot of late-summer heat will eject northeast across the Mid West and Ohio Valley. Sunday through Tuesday will feature temperatures that top out in the upper 80s to around 90°.
IV. A cold front will drop in by the middle of next week. Scattered showers and thunderstorms will accompany the frontal boundary, but the bigger story will be a dramatic change to a much cooler regime as we get set to put a wrap on the month of August. In fact, temperatures may grow cool enough to allow some 40s to develop across central and northern parts of the state at night. Meteorological summer sure looks like it’ll end with more of a fall-like feel…

High pressure will remain in control of our weather pattern through the early portions of the new week. This will supply continued dry conditions, along with plentiful sunshine. Humidity values will remain comfortable as we open the work week before turning increasingly muggy as midweek nears.
High pressure will keep us dry through early week.
As high pressure moves off to the east, a southwesterly air flow will help moisture return to the state by mid and late week. As a cold front enters the picture, overall coverage of showers and thunderstorms will increase and become scattered to numerous. We’re not expecting any sort of all-day rains, but chances of getting wet from time to time will go up Wednesday through Friday.
Thunderstorm coverage increases mid and late week.
Rainfall totals should fall in the 0.50″ to 1.00″ range for most, but there will be a few folks who pick up locally heavier amounts the second half of the week.
As of now, we think the cold front will pass Friday evening and set-up another pleasant weekend with seasonable temperatures. The stretch of gorgeous August weekends’ appears to roll along.
What else we’re working on: With us about to flip the page to the second half of August, thoughts continue to shift to the upcoming meteorological fall and winter seasons ahead. Early data paints an “intriguing” look, complete with high latitude blocking and neutral ENSO look. Winter enthusiasts should like the look overall as this will have an impact on the prospects of cold getting going earlier than recent years past. Much more on fall and winter in the weeks ahead… The other big item of interest has to do with the tropics. A new disturbance will traverse the MDR (Main Development Region) this week and given the overall upper level pattern over the CONUS, we’ll have to keep an eye on the East Coast Weeks 2-3.

1.) July, MTD, is running slightly cooler (- 0.1°) and much wetter (+ 2.31″) than average across the region.
2.) While the radar is rain and storm-free this morning, a left over boundary, combined with daytime heating will help spark isolated to widely scattered storm coverage this afternoon.
3.) The big weather story this week will be an increasingly hot and humid feel once to mid and late week, including the weekend. While today will continue the theme of slightly cooler than average from the weekend, we’ll more than make up for the refreshing feel later this week. Highs will push to around 90° Wednesday through Sunday as the ridge expands.
4.) Despite the hot and humid feel that develops this week, it won’t last. Like so many other times this summer that heat tries to build east, the transient weather pattern will continue to prevent it from “hitting and holding.” You guessed it, as we transition from the hot conditions to cooler weather next week, rain and storm chances will be on the increase, including the potential of heavy rain. As of now, best rain and storm chances appear lined up for late week through the weekend and into early next week.

1.) Temperatures are running much warmer across the Mid West and Ohio Valley this morning. In most cases, communities are 15° to 20° ahead of this time 24 hours ago. Ah, the fall-like feel was nice while we had it!
2.) With the increasing warmth and humidity will also come an increase in shower and thunderstorm chances today through Saturday. Most widespread coverage of thunderstorms should occur during the evening hours today and Friday night into Saturday morning. Drier air will try and work in Saturday afternoon into Sunday. Here’s a look at the forecast radar valid at 7p this evening.
3.) While we should dry things out Saturday afternoon into Sunday, active times will return early next week. We’ll have to fine tune timing, but the period Monday into Independence Day may feature a rather strong storm complex moving in a southeast fashion across the region. Again, details still have to be determined. While strong storms are possible at some point during the period, more dry time than wet can be expected.
4.) The latest JMA Weeklies are in and while we’ll have a more extensive post this evening on the weekly breakdown, the screaming message to us is an active period continues along with cooler anomalies setting up shop across the central, including our region.

Today’s 12z model suite is in and it remains consistent on a more active weather pattern returning to the delight of many Hoosiers! A blend of the GFS and European 10-day rainfall numbers print out 2″ for Indianapolis. The GFS ensemble ‘mean’ (a blend of 21 individual members) agrees.
Best overall coverage of showers and thunderstorms should come in (3) waves over the upcoming 10-day period:
While we don’t see any sort of uniform type rains in the upcoming period, the “smattering” of storms should help most neighborhoods get in on the rainy “goods” at one time or another over the upcoming week and a half. Keep in mind, we’re in mid-June now and it’s mighty difficult to ask for anything much more than scattered storms this time of year on through late-summer…unless a tropical entity gets involved. That’s just the way this time of year is. With that said, localized torrential downpours are a very good bet from time to time, beginning as early as mid-week, as precipitable water values approach, or exceed, 2″ (about as moisture-rich as you can ask the air mass to get around these parts) into the upcoming weekend.
As I type this outside on the back porch this evening, I hear the sounds of sprinklers in full-force through the ‘hood. Thankfully, Mother Nature will help save on the water bill later this week. Longer-term, you’ll hear us use the word “transient” many times this summer when discussing the overall weather pattern. Thankfully that tends to result in a fairly busy time of things. Before you know it, college football season will be back (83 days until my beloved Auburn Tigers kick-off), those wetter autumn storms will return, and thoughts will begin to shift to winter (they may have already started here :-))- not that we’re trying to rush summer away or anything…
