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…

Highlights:
Dry Close To The Weekend…First and foremost, our thoughts and prayers are with Texas as one of the worst flood events in our country’s history is unfolding this morning. With days of heavy rain ahead, an additonal 20″-30″ will fall on eastern Texas. Just horrific.
Here on the home front, we’ll wrap up the weekend on a dry note, but upper level energy will drift overhead late tonight and help generate scattered showers and thunderstorms as early as the predawn hours Monday. We’ll maintain a bit of an unsettled regime into Tuesday before dry conditions return Wednesday.
A backdoor cold front will push through central Indiana Thursday and a broken line of showers and thunderstorms may accompany this frontal passage. A northeasterly flow will usher in an unseasonably cool, early fall-like, close to the work week.
Looking ahead, an even stronger cold front has it’s eyes set on the region late next weekend or early the following week. Strong thunderstorm potential is present with this storm system followed by the coolest air since last spring…

Good morning, friends! Temperatures this morning are in the lower 50s for many across central Indiana as our “hint” of fall continues to wrap up the month of August. I…

Highlights:
Cold Front Arrives…A cold front is pressing into the state today and generating unsettled weather across the region. Widespread heavy rains fell overnight across northern parts of the state (areas just west of Lafayette have picked up 3″-4″ of rain during the past 24 hours). Scattered to numerous showers and thunderstorms can be expected through early evening before a much drier and cooler air mass arrives tonight behind the frontal passage.
That drier and cooler regime will set the tone for the rest of the week and weekend. High pressure will settle in and provide plentiful sunshine. Additionally, cool, Canadian air will pour south as we progress through the second half of the week. This will result in well below normal temperatures and conditions that will feel more like mid to late September rather than late August.
Tropics: Harvey is likely to stage a comeback over the next few days once he emerges into the southwest Gulf of Mexico. Folks with interests along the Texas coastline should certainly monitor Harvey for tropical implications as the weekend approaches. An interior heavy rain/ flood threat will result, as well.

Highlights:
Time To Sweat…A hot and increasingly humid airmass will be with us as we open a new week. While most of the upcoming 24-48 hours will remain rain-free, we will mention chances of an isolated to widely scattered thunderstorm Monday. Most will remain free of rain and storms, but those lucky folks who do find themselves under a storm Monday can expect to pick up a quick 1″ of rain. Better overall coverage of showers and thunderstorms will develop late Monday night into Tuesday.
Typically, a pattern change such as what we’ll undergo this week (summer-like to early fall-like) would yield widespread showers and thunderstorms. However, a look at short-term, higher resolution data isn’t particularly “excited” about widespread significant rainfall across central Indiana. We expect a weakening complex of thunderstorms off to our northwest to drift southeast Monday night. Depending on how quickly this complex weakens will determine rainfall amounts, locally. Additionally, it’s very possible this weakening storm complex will serve to limit new thunderstorm development Tuesday as the cold front moves closer. We do note high resolution data places emphasis on northern and southern parts of the state for heaviest rains and it’s tough to disagree with that idea given what we’re looking at right now. Stay tuned.
Regardless of the rain and storm situation, locally, we’ll all turn significantly cooler by midweek. In fact, temperatures will grow cool enough to feel like mid-September. Dry conditions will carry us into next weekend.

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…

Highlights:
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!

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.
