It will be a hot and hazy Father’s Day weekend. An Air Quality Alert is in effect today through Monday, as stagnant air is in place. This can cause health issues for those with respiratory problems. Take it easy outdoors today. It’s advised to wait to gas up and mow the lawn until later in the evening.
Temperatures today will climb into the upper 80s under mostly sunny skies.
It’ll be clear and mild this evening with lows in the mid 60s.
Father’s Day will be sunny and hot with light winds out of the southwest. Afternoon highs climb into the low 90s.
The first day of summer officially arrives on Monday at 6:34 PM EDT. It will feel like it, with temperatures climbing into the mid 90s. Humidity will also be high. We are not expecting record breaking temperatures, as the record is 100 degrees set back in 1953, but it will likely be the hottest day of 2016 so far.
The large ridge of high pressure producing this dome of hot air, will gradually drift to the west. As it does, the periphery of this dome will be over Indiana by late Monday night.
A cold front will start to move in, bringing storm chances overnight Monday and Tuesday. There is a risk of a strong to severe thunderstorm with the main threats being heavy rain and damaging winds.
Much cooler air arrives by mid week, allowing cooler than normal temperatures to take over.
TGIF! There are no significant changes to our Father’s Day weekend forecast. We’ve had hot and sunny going all week… and that’s playing out. Humidity is much more tolerable today and the warm temperatures in the 80s subside nicely after sunset this evening.
A refreshing north-northeasterly breeze makes for a pleasant finish to our day and lows tonight eventually drop back down into the 50s and 60s. Expect a quick warm up tomorrow with temperatures in the 80s by noon and nearing 90 degrees for highs.
Unfortunately the weather pattern causing temperatures to go up will cause air quality to go down. The combination of hot, stagnant air allows unhealthy levels of ground ozone to emerge this weekend. As a result Knozone Action Days have been for the Indianapolis metro area for Saturday, Sunday and Monday. Avoid drive-thru’s and mowing your lawns until after 6pm if possible.
Father’s Day will be sunny and hot as temperatures climb into the 90s. The hottest air of the year thus far hits Monday when highs jump into the mid-90s.
A good portion of the U.S. will be under the influence of a large area of upper level high pressure… also known as a ridge in the jet stream. Sinking air under the high produces a hot dome that keeps the sky mainly cloud-free and forces rain/storms to its periphery similar to steam around the lid of a pressure cooker.
This feature keeps us dry until it breaks down and sinks southwestward Monday night into Tuesday of next week. Scattered storms Tuesday will be followed by another shot of refreshing Canadian air mid to late next week.
Have a great weekend and Happy Father’s Day to all of the dads celebrating Sunday – Sean Ash
Humidity continues to fall today, thanks to the breezy winds out of the north. Dewpoints will be in the mid 50s this afternoon with mostly sunny skies.
Afternoon highs will climb into the mid 80s.
It will be mostly clear and pleasant this evening with an overnight low in the upper 50s.
The weekend will be hot, sunny and dry. Temperatures will climb into the upper 80s Saturday and low 90s on Sunday. It will be great lake or pool weather!
Monday will be the hottest day of the week with highs in the low to mid 90s.
A cold front arrives Tuesday. That will bring the chance of a few scattered showers and thunderstorms and cooler temperatures.
Tuesday will still be hot with highs in the upper 80s.
Temperatures fall back to normal by Wednesday with mostly sunny skies and highs in the low 80s.
The wind of change is slowly but surely delivering refreshing air into the viewing area, but patience required with some areas still dealing with high heat and humidity.
There’s an very impressive 40 degree temperature spread from north to south across Indiana… where the breeze off of Lake Michigan delivering 50s in South Bend while Evansville remains in the upper 90s! Eventually comfortable air reaches area wide and sets the stage for a fantastic start to the weekend.
Clouds this evening clear overnight to allow temperatures to drop into the 50s and lower 60s. Cool enough to shut-off the A/C, open the windows and air-out the house. Expect a bright sky tomorrow with warm highs in the mid-80s.
No changes at all to our Father’s Day weekend forecast of sunshine, upper 80s Saturday and lower 90s on Sunday. The hottest day in the 7 day forecast is Monday when highs hit the mid-90s… likely the hottest of the year thus far.
We’re still expecting a period of storminess to return to the Great Lakes and Ohio Valley Monday night into Tuesday. This brings the potential of more heavy rain and possibly severe storms. Stay tuned and have a great evening – Sean Ash
After rounds of heavy rain, and severe storms moved through Central Indiana Wednesday, today will be a chance for us to dry out. Damaging wind and flooding top the storm reports from the last 24 hours.
I want to show you some of the rain totals from yesterday.
With the heavy rain in western Marion County, a Flood Warning will remain in effect until 6:30am.
Highs will reach the mid to upper 80s today with lower humidity. Skies will become partly cloudy, and there’s a slight chance for an isolated shower late in the day. What you’ll notice is the wind picking up out of the northwest with gusts up to 25 mph.
Tonight skies become partly cloudy to mostly clear, and it is going to be an extremely comfortable start as temps fall into the low 60s by Friday morning.
Friday will be beautiful with sunshine, and highs in the mid 80s.
We warm up for the weekend with highs close to 90, but sunny skies will remain.
Our next chance for showers and storms will arrive Tuesday.
Storms are firing up around Central Indiana and will deliver torrential rain along their path. Flash flooding rain rates of 1-2″ per hour and lightning remain the most likely threats with storms today, but extreme instability keeps all of the viewing area in a Level 2 (on a scale of 1-5) risk today. Severe wind gusts and/or hail are possible before 8pm so please have a way to get watches and warnings.
You’ll also notice oppressively humid conditions today and that remains a part of the evening forecast. Heat indices are near 100 degrees in easily the most uncomfortable day this year thus far. Oppressively humid today but the Muggy Meter gets comfortable Friday morning and stays there for a couple of days.
The threat of severe weather, and storms in general, quickly diminishes after sunset and quieter times are ahead. Areas of fog are possible overnight and early Thursday morning. It won’t be as muggy tomorrow but still humid and warm in Central Indiana with highs in the mid to upper 80s.
Noticeably cooler highs in the 70s are likely in North Central Indiana where are refreshing northerly wind takes shape and less sunshine.
Friday looks fantastic with comfortably warm highs in the low to mid 80s with sunshine. Father’s Day weekend features sunshine and highs near 90 both days. Stay weather aware this evening friends – Sean Ash
After a stormy morning shower and thunderstorms are moving out of Central Indiana, and the sunshine is moving in, but that’s not necessarily a good thing. Sunshine will help aid our storm development as we go into the afternoon. Highs will reach the upper 80s to low 90s today, with oppressive humidity.
Storms should start to develop after 1pm, and we are under a risk for severe weather through the evening.
The biggest threats are damaging wind and localized flooding.
The storms should exit by 9pm tonight, with lows dropping into the low 70s by tomorrow morning.
Thursday will be breezy, with wind gusts up to 25mph out of the northwest, and there’s a very slight chance for an afternoon shower. Highs will warm into the mid 80s, and it won’t be as humid.
The humidity will continue to be comfortable Friday for our coolest high in the 7 day forecast. We’ll be back in the 90s by Sunday.
Finally getting some dry time after the wettest day overall in Central Indiana since May 1st. Much of the Indy metro area had over an inch of rain and there were a few reports of three to four inches locally.
Areas of dense fog may be develop overnight as a result and we’ll likely see more showers and storms arriving by sunrise from Illinois.
Activity in the morning likely produces downpours and lightning. The exit time of morning activity plays a key role in severe chances Wednesday afternoon.
Tropical moisture makes for uncomfortable conditions Wednesday as the Muggy Meter hits oppressive levels of humidity. If temperatures can achieve the upper 80s/lower 90s this moisture helps increase instability for severe storms too.
At the time of this posting we’re only expecting isolated storms in the afternoon and early evening… but they will still pose a damaging wind and/or hail threat.
The risk of severe weather quickly ends before 10pm tomorrow and we’ll begin Thursday rain-free. An impressive upper disturbance pivoting across the Ohio Valley late Thursday afternoon keeps isolated showers and storms in play.
We continue to advertise a sunny Father’s Day weekend. Highs Saturday will be in the mid-80s and then climb back into the 90s for Father’s Day. Long range indicators suggest another stormy pattern setting up over the Great Lakes/Ohio Valley this time next week. Check back for radar updates – Sean Ash
Central Indiana continues to battle areas of heavy rain and locally strong storms. Many rain gauges around the Indy metro area picked up nearly 2″ totals and a whopping 3.14″ reported near Monument Circle.
Areal Flood Advisories are up for portions of southern Indiana that received 2″ to 3″ of rainfall in three hours.
Between now and Wednesday afternoon there will be a few more waves of heavy storms to deal with it. If temperatures can warm to near 90 degrees tomorrow some of the storms may become severe during peak heating… with damaging wind the main threat.
But any storms, or showers for that matter, likely deliver heavy rain rates due to high levels of moisture in the atmosphere. Severe weather tomorrow hinges on how much coverage of storms, cloud cover and fog we begin. Less of those means a better chance of realizing the Level 2 risk.
A drier pattern emerges late week though isolated showers are possible late Thursday afternoon. We continue to advertise a sunny Father’s Day weekend. Highs Saturday will be in the mid-80s and then climb back into the 90s for Father’s Day.
Check back for radar updates – Sean Ash
As expected, scattered storms will be on the radar this afternoon, however not everyone will see rain. Those that do, will likely have heavy downpours, and frequent lightning in thunderstorms.
Some storms may be strong to severe with damaging wind and hail, however flooding will also be a concern as these rainmakers are slow movers.
Spots that don’t see rain will warm into the upper 80s to low 90s this afternoon.
Tonight rain and storm chances remain, but will diminish in coverage.
We’ll prepare for more tomorrow, with a greater chance of severe storms. We will be watching the radar, for damaging wind and large hail, especially during daytime heating in the afternoon.
After Wednesday, we start to dry out with just isolated rain chances Thursday, and a brief break from the heat before another run at the low 90s by Monday.
