Summer Weather Gives Way To An Early Fall Feel…Seasonably warm and humid conditions will help power widely scattered afternoon and evening thunderstorms again Wednesday. More widespread showers and thunderstorms will arrive Thursday evening into early Friday as a cold front sweeps through the state. Winds will shift around to the northwest and turn gusty Friday afternoon, helping usher in an unseasonably cool air mass for the first Friday of August. This cooler regime will remain with us through the weekend. A quick-moving light shower is possible over the weekend, but most of the area will remain rain-free with mixed clouds and sun.
Temperatures will remain below seasonal norms early next week (and really throughout the majority of the first half of August) with scattered rain chances returning to our forecast. Looking beyond the current 7-day period shows our next storm system of significance approaching mid-to-late next week.
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 0.00″
- Rainfall: 0.50″ – 1.00″ (locally heavier amounts)

Welcome To A New Work Week…As we open the new work week, we’ll continue to deal with the same weather pattern that provided us the delightful weather over the weekend. High pressure will grudgingly give up control Tuesday into Wednesday with moisture returning. Initially, coverage of showers will be “spotty” at best, but better coverage of showers and thunderstorms will return as we progress into midweek. Thursday appears to be the wettest day as a cold front pushes closer to the region.
That cold front will sweep through the state Friday morning and result in a MUCH cooler air mass filtering into the region as we close the work week and head into the weekend. While we’ll certainly notice the much cooler air, we have to maintain mention of a passing shower over the weekend thanks to lingering upper level energy. Despite scattered showers around the region, most of the weekend will be rain-free. The bigger story will be the late-September like air over the weekend.
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 0.00″
- Rainfall: 0.50″ – 1.00″

Highlights:
- Wall-to-wall sunshine
- Comfortable temperatures
- Rain chances return
- Even cooler next weekend
Can’t Beat This Weather…The short-term is very simple. High pressure will dominate our pattern through early next week and result in very refreshing conditions. With a north-northeast flow in place, unseasonably cool and dry air will continue to flow into the region through the weekend. Get out and enjoy it!
Temperatures will slowly moderate heading into mid week and moisture will return ahead of a cold front Wednesday into Thursday. Greatest overall rain coverage should arrive on the scene Thursday, including chances of thunderstorms. Similar to this week, the cold front will pass Thursday night/ Friday morning and result in a drier ending to the work week. An early look at next weekend shows another anomalous trough digging into the Mid West. The end result will likely be temperatures that are even cooler than this weekend. Mid-upper 70s for highs, perhaps?!
Upcoming 7-Day Precipitation Forecast:

Highlights:
- Turning more humid this afternoon
- Heavy rain Thursday
- Cooler and drier weekend ahead
Heavy Rain Tomorrow…Wednesday is getting off to a pleasant and beautiful start across the Hoosier state. Sunshine will be with us throughout the day, but our pleasant air mass that we’re awaking to will grow increasingly moist this afternoon and evening. Our next storm system approaches late tonight and will help push widespread rain and thunderstorms across the state early Thursday morning. With such high water content in our air mass, expect periods of heavy rain across the region. Localized flooding will result.
The trade off to the wet and stormy Thursday will be an incredible weekend. Despite a few lingering showers Friday, we’ll notice a dramatic drop in humidity Friday night and this will set the stage for a refreshing last weekend of July. In fact, temperatures will grow cool enough both Saturday and Sunday mornings to perhaps trigger a feel of early autumn for some. Plentiful sunshine can be expected along with unseasonably low dew points with a northeasterly flow in place.
Temperatures and moisture levels will slowly increase as we get into early next week. With the increasing humidity, expect increasing chances of showers and thunderstorms towards the middle of next week.
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 0.00″
- Rainfall: 2.00″ – 3.00″

Highlights:
- Less humid air builds in
- Mid-week storms
- Refreshing weekend
Pleasant Open To The Work Week…High pressure will build overhead today and result in a dry open to the work week. A surface front moved south through the region late last night and north winds will help drier air continue to build in as we move through the day. By this evening, we’ll really feel the more refreshing brand of air.
We’ll remain rain-free through Tuesday before our next cold front approaches late Wednesday into Thursday. Most of Wednesday will remain dry, as well, but we’ll mention chances of a late night thunderstorm arriving from the northwest. Better overall coverage of showers and thunderstorms can be expected Thursday.
Timing is our friend this go around as the front passes Thursday evening, allowing a much drier and cooler air mass to build in. Considering this is the last weekend of July, it’ll feel very, very pleasant.
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 0.00″

Highlights:

Mother Nature Calls…Many awoke early this morning as a complex of thunderstorms rumbled southeast into central Indiana. Some local rain gauges are already registering 2″+ across the region. Eventually, we think clouds will thin enough later today to allow temperatures to zoom close to 90°. Factor in the moisture-rich nature of our air mass and heat indices will approach 105° later this afternoon.
We’ll keep mention of scattered storms this evening and while most of the daytime Saturday looks dry, we’ll have to keep a close eye on Saturday night as models try to deliver another round of storms into central Indiana. Ingredients will be in place for the potential of severe thunderstorms Saturday night, with damaging winds being the biggest concern from a severe perspective.
A frontal boundary will push south and we’ll finally begin to see humidity levels fall as we close the weekend and open next week. It’ll feel very refreshing during the Monday-Tuesday stretch.
Heat, humidity, and storm chances return by the middle of next week.
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 0.00″
- Rainfall: 1″ – 3″

Highlights:
- Increasingly hot and humid
- Isolated storm coverage becomes more widespread
- Relief next week
Air You Can Wear…The big weather story will be the increasingly hot and humid feel as we progress through the week and on into the weekend. The combination of dew points in the 70s and wet soils across the state should “beat back” the heat from getting to where it otherwise could (mid-upper 90s), but it’ll feel oppressive, nonetheless. Plan to hydrate and wear cool, lightweight clothing if you plan to be outdoors for any length of time.
While we can’t completely rule out a renegade storm through Friday, most neighborhoods will remain free of any rain through the remainder of the work week. Better coverage of showers and thunderstorms will increase over the weekend into early next week as the transition from hot, humid weather begins to give way to a more pleasant feel.
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 0.00″

Pleasant Start; Stormy Finish…After we got rid of the low level clouds and fog Saturday, it turned out to be a gorgeous day! The balance of our Sunday will also be very pleasant, but a frontal boundary will push through the state this evening and will be sufficient enough to kick up a line of showers and thunderstorms that will impact central IN this afternoon and evening. One or two of the storms could reach severe levels (large hail and damaging wind).
As we look forward, the big weather story this week will be the increasingly hot and muggy feel by late-week. Factor in that highs will approach 90° the second half of the week, along with dew points exceeding 70° and the stage will be set for a truly “oppressive” feel. Prepare to sweat.
Along with the increasingly heat and humidity, we’ll also note an increase in overall coverage of showers and thunderstorms through the late-week stretch. Individual disturbances will create periods of more widespread storms and with such a moisture rich air mass in place, expect periods of locally heavy rainfall.
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 0.00″
- Rainfall: 1.50″ – 2.50″

- More refreshing air arrives for the weekend
- Quiet start to next week
Stormy Afternoon On Deck…A frontal boundary will slip into the state today and slowly push south over the next 24 hours, eventually making it out of the state Friday. The combination of this trigger (front) along with a genuinely “soupy” air mass (precipitable water values will be north of 2″ and dew points will remain in the low-mid 70s) will result in increasing storm coverage this afternoon into the evening hours. Some of the storms may become severe and it also won’t take much for flash flooding to develop where storms train. In some cases, these storms will dump rainfall rates of 2″-3″/ hour. From a severe stand point, we’re most concerned for the potential of damaging straight line winds.
Thankfully, we’ll clear things out in time for the upcoming weekend. With the exception of a few morning thunderstorms downstate Friday, the trend will be a drier one and that will continue into Saturday. Along with the drier air, we’ll also note slightly cooler temperatures. It’ll feel much more refreshing than the past couple days.
A weak reinforcing cold front will sweep through the state Sunday evening and this boundary could kick-up a scattered thunderstorm or two Sunday afternoon-evening before we return to dry times Monday and Tuesday. Moisture (and heat) will return by the middle of next week.
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 0.00″
- Rainfall: 1″-2″ (locally heavier totals)

Highlights:
- Tuesday and Thursday appear to be the stormiest days
- Drier trend to close the week; open the weekend
- Humid air gives way to a more refreshing feel
Stormy Periods…Storms are building across west-central Indiana this morning and these will settle into the city, itself, as the rush hour nears. This is only the beginning of multiple rounds of thunderstorms that will ride in a northwest to southeast fashion across central Indiana today. With dew points in the lower and middle 70s and precipitable water values exceeding 2″, additional flash flooding will result today for some communities where storms “train” over the same areas. A couple of strong-to-severe storms are also possible this afternoon with large hail and damaging straight line winds the biggest concern.
While we can’t rule out a passing storm Wednesday, overall storm coverage should be significantly reduced tomorrow as we get in on bit of a breather before another active time of things Thursday.
A surface front will settle south Friday. Best thunderstorm chances should occur during the front half of the day before a drier regime builds in from the north Friday evening and into Saturday. Temperatures will cool slightly, but we’ll really be able to notice a dramatic reduction in the humidity.
Sunday should be mostly dry, but we note a weak secondary boundary that will pass late in the day. This may be just enough to kick up a shower or thunderstorm Sunday afternoon or evening.
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 0.00″
- Rainfall: 2″-3″ (locally heavier amounts)
