Thursday Morning Weather Notebook: Changes Brewing To Close August…
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…

Warm And Muggy; “Splash And Dash” Storms…
Highlights:
- Scattered storms
- Saturday showers
- Surge of heat ahead of a late week cool down next week
More Dry Time Than Stormy…A warm and moist southwesterly air flow will have things feeling quite muggy today. This tropical feel will also help fuel scattered thunderstorms by evening, continuing into tonight. While everyone won’t get wet today, those that do have the potential of picking up a quick 1″ in a short period of time. A cold front will cross the state Thursday and will keep scattered showers and thunderstorms going. While this isn’t a uniform soaking, we’ll take what we can get as things have been bone dry around these parts lately.
After a quiet and slightly cooler Friday, an upper level disturbance will deliver another round of showers and embedded thunderstorms Saturday. Dry weather will return to wrap up the weekend Sunday.
Looking ahead, a surge of heat, albeit brief, will have things feeling quite toasty around the Mid West early next week. We think we flirt with, or exceed, the 90° mark both Monday and Tuesday. Thunderstorms will increase Tuesday as a cold front drops in from the northwest. Behind the front, data still paints a much cooler regime for the second half of next week; fall-like!
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 0.00″
- Rainfall: 0.75″ – 1.25″

Classic Mid-August Weather…
Highlights:
- Dry open to the work week
- Unsettled times return
- Cooler air heading into the weekend
Storm Chances Begin To Increase…While southern portions of the state will get wet today, dry air should result in a rain-free Monday here across central Indiana. That will begin to change later this week as moisture returns and that muggy summer feel develops for midweek. In addition to the increasingly humid nature to our airmass, a cold front will approach from the west. Coverage of storms tomorrow should remain few and far between (isolated), but overall coverage will increase Wednesday into Thursday (scattered to numerous).
The cold front will sweep to our east Thursday night and result in a beautiful close to the work week, complete with cooler temperatures and lower humidity levels. The weekend will feature a disturbance dropping in from the northwest and this will be sufficient enough to kick up scattered showers and thunderstorms Saturday afternoon and evening before dry times return Sunday.
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 0.00″
- Rainfall: 0.50″ – 1.00″

The Week Opens Quiet Before More Unsettled Times Return…
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.

Gorgeous Weekend; Humidity Returns Next Week…
Highlights:
- Beautiful weekend dialed up
- Humidity returns
- Scattered storms late week
Refreshing Conditions Continue…A cold front settled south of the region last night, allowing drier and slightly cooler air to filter in during the overnight. That sets the stage for the weekend as we can expect dry and refreshing conditions, along with below average temperatures.
Dry skies will continue into the new work week, but humidity will slowly begin to increase once we get to midweek. A southwesterly air flow will develop ahead of our next storm system that will deliver scattered thunderstorms by Thursday. Shower and thunderstorm chances will continue Friday morning, however, early indications suggest next weekend is also dry.
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 0.00″
- Rainfall: 0.25″ – 0.75″
Cool August: The month has opened impressively cool with a CONUS average anomaly of – 2.75° through the 10th. More specifically to Indianapolis, we’re running 3° below normal through the 11th.

Scattered Storm Chances Return…
Highlights:
- Scattered t-storm chances return
- Mostly dry, pleasant weekend
- Rain chances return early next week
Frontal Boundary Moves In Friday…Another sunny, pleasant late-summer day is on tap before a cold front approaches late tonight. This frontal boundary will be responsible for creating scattered thunderstorms Friday across central IN. Current indications suggest rain won’t be widespread or particularly heavy, but don’t be surprised by a local downpour or two as we wrap up the work week.
Dry and pleasant weather will return over the weekend, complete with plentiful sunshine. Our next storm system approaches Sunday night into Monday with the potential of more widespread rain. With that said, there’s considerable model disagreement with regard to overall rain coverage and amounts Monday (European is the most aggressive with widespread rain). We’ll go with a blend of the two for now (scattered thunderstorm chances) and hope for better agreement later today. We’ll provide updates after taking a good look at 12z data.
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 0.00″
- Rainfall: 0.50″ – 1.00″
