With heat index values forecast at 105 degrees, the southern part of Indiana is under a heat advisory from Friday at noon through Saturday at 7pm. Bedford, Seymour and North Vernon are included. Highs will be in the range of 90 to 95 degrees, but it will feel like 105+.

Take precautions from the heat. If you have to spend time outside, find the shade and drink lots of water. Check on family and friends that might not have air conditioning. Your pets will need extra shade and water. The high heat and high humidity will last through the weekend.

Scattered storms are also in the forecast through the weekend. The storms will bring heavy rain and the the threats for flash flooding and damaging winds. There is a slight risk for severe weather on Friday.

A few storms are possible late Thursday night and early Friday. There is a better chance Friday afternoon and evening. We will keep you updated on any changes to the timing.



Hottest Streak Of The Year

Hottest Streak Of The Year
Published: .

All you need do is step outside and you can feel the heat and humidity build. In a week when St.Louis has had 80 degree weather at 5am....(no kidding), we will tap into the Plains States big outbreak. The current heat wave covers a good 2/3rds of the United States. Heat indices in many states, like Indiana will be over 100 in between now and Sunday afternoon.

So...what should you do? Here are 4 steps to use as an action plan during the next few days.

1. Limit afternoon activity. This is when the most problems with heat stroke etc. occur.

2. Hydrate, hydrate, hydrate.

3. Keep an eye on the elderly, infirm and toddlers . Check on folks without air conditioning.

4. Download the WTHR weather app to stay informed all day long.

Right now, all of the activities surrounding the Brickyard look warm and humid with scattered storms. the cool down comes next week with Tuesdays high 78 degrees.



Air Quality Action Day Issued For Wednesday

Wednesday is a Knozone Action Day

Live Doppler Forecast - 7-18 noon update

We've advertised our upcoming hot stretch for nearly a week now and the time for talk is just about over. Heat indices have are cracking 100° degrees to our west... where Excessive Heat Watches/Warnings and Head Advisories are posted.

Due to high levels of soil moisture and humidity, it seems unlikely Central Indiana will hit Excessive Heat Warning criteria (peak heat index of 110° or higher). However it's going to be plenty uncomfortable and dangerous with expected peak heat indices of 100°-105° Thursday-Saturday.

This may require Heat Advisories for the WTHR viewing area going. Please use common sense if you must be outside... including taking frequent breaks, hydrating, comfortable clothes, and seek A/C as much as possible.

Another byproduct of this summer set up is deteriorating air quality. The combination of light wind and hot air allows pollutants to collect near the ground and in this case we're concerned about unhealthy levels of ozone.

As a result Wednesday, and likely the rest of the week, will be an Air Quality Action Day for many cities in Central Indiana... including the Indianapolis metro area. The air quality will be unhealthy for sensitive groups and those in that group should limit outdoor exposure.

You can do your part by holding off on mowing the lawn until near sunset, avoid drive thrus, idiling your car, or anything that adds pollution.

The hot, humid air also breeds heavy storm clusters between now and early next week. While initially it appears the main track for storms will be closer to the Michiana border... we're expecting multiple rounds of at least scattered heavy storms beginning Friday and isolated heavy storms both Wednesday and Thursday.

Long range signals suggest relief arriving early next week with a welcome cooler, less humid air and a refreshing breeze. But we're going to earn it between now and then - Sean Ash



Photogenic Storm This Evening

A persistent and slow-moving storm in Marion County this evening produced quite the show. It certainly had supercell characteristics and produced some small hail.

Radar Image 8:41pm Sunday 7/16/2017

Around 8:40pm Sunday evening this is what the storm looked like on Live Doppler 13 Radar in the above image. At the same time several people tweeted me with spectacular views of its cumulonimbus. Below is what the storm looked like from Avon. The anvil is easily identifiable and on the top left of the anvil there's a faint over-shooting top... which occur from a storm's updraft.

The over-shooting was identifiable on visible satellite imagery just before sunset.


Because it was isolated and happening around sunset the color was maximized. Below are some more tweets of the storm. Nature never ceases to amaze

Copious amounts of rain fell last night into this morning.

The hardest hit area was northern Marion county.

There was a report of 2.6” of rain that fell in 2 hours in Castleton.

Here is a rain report in Fishers in Hamilton county.

There were many flooded areas in Hamilton and Marion counties.

There were even a few wind reports.

Before I headed in to work this morning, my gauge collected 1.51” of rain in Fishers.

The storms brought heavy rain, gusty winds and lightning. This is a short video of my backyard. A stream formed from all the heavy rain and the lightning was intense.

Threat For More Storms - Thursday Forecast

It has been an active week of weather, with several rounds of severe storms. There were tornadoes on Monday evening, flash flooding and damaging winds on Tuesday and Wednesday. The threat for severe weather continues. On Thursday there is a slight risk for severe storms. Here is that threat forecast and the outline for the severe risk.

With more heavy rain expected, the National Weather Service has central Indiana under a flash flood watch through Friday morning. We have already experienced flash flooding this week. The ground is saturated and creeks, rivers and streams are high. Any additional heavy rain will quickly cause flooding. Stay weather aware through Friday.



Record Rainfall Produces Widespread Flooding

It's been a wild 24 hours in Central Indiana that began with confirmed tornadoes in north-central parts of the state and finished with a daily rainfall record at Indianapolis.

National Weather Service offices from Indianapolis and North Webster confirmed touchdowns on the Carroll/Cass county line and another in Miami County. These are preliminary reports and more may be added to the list. Click here for pictures and videos of the tornadoes and damage.


While tornadoes impacted a small area, flooding rainfall covered most of the viewing area. A complex of storms followed a path right through the heart of Central Indiana... delivering not only flooding rain rates but swaths of wind damage that stretched from the Illinois state line to Ohio. Numerous trees were toppled in Crawfordsville, Zionsville, Carmel, north side of Indy, Shelby County, and widespread damage in Wayne County too.

Rainfall amounts were flat-out impressive as several gauges eclipsed 3" amounts mainly in a 3-4 hour window. Rivers, creeks, ditches are swollen and some roads impassable with flood warnings continuing this hour.

Indianapolis had not only a daily record for rainfall on this date but this marked the 8th wettest July day on record. We're already near the average summer rainfall and we're expecting a few more heavy storm clusters before a dry weekend.



Timing Monday Night Storms

Published: .

A severe thunderstorm watch is in effect from Indianapolis north until midnight. Damaging winds and large hail are possible. All storms will contain lightning and heavy rain. That heavy rain brings the risk for flash flooding.

Here is the latest timeline for the storms to move through central Indiana. The complex formed across northern Illinois and northern Indiana around 6pm. It is forecast to move south and impact central Indiana from about 8pm Monday to 3am Tuesday. Stay tuned for updates to the timing.
