Indy Finally Hits 90 Degrees And Heavy Evening Storms

Posted By · August 25, 2014 at 3:46 pm

Much of the next few hours will be just plain hot and humid.  But we’re monitoring strong to severe storms crossing into northern Indiana.  Our thinking is this cluster will continue building south-southeastward, feeding off of extremely unstable air in place.

RADAR 4PM

The latest HRRR model run picks up on the expected storminess, but likely is too slow with the timing based on current radar trends.  Storms are possible in central Indiana, and the Indianapolis metro, by 6-7pm.

HRRR MODEL

Heavy rain (1-3″) and very frequent cloud-to-ground lightning are likely, while 50mph+ gusts are possible.

STORM THREATS

The other big story is Indianapolis hitting 90 degrees for the first time this year.  This equates to the hottest day of the year thus far and snaps a 347 day streak without 90 degrees… the sixth longest streak on record.

4PM TEMPERATURES 4PM HEAT INDEX

Heat indices in the upper 90s and lower 100s make it challenging being outside for long periods of time.  Be safe and smart this evening.

STREAK OVER LATEST 90

 

The air mass blanketing the Ohio Valley remains tropical in nature.  This “super juice” will help feed the downpours and keep it uncomfortable for the next several days.

dewpoints MUGGY METER

We don’t anticipate a break in the oppressive Muggy Meter anytime soon, with uncomfortable humidity lingering into the Labor Day weekend.

POLLEN COUNT

The pollen count is also very high and will likely stay that way for the remainder of the week.  It’s Sniffle City and feeling like Key West at the same time… without the beach!

RPM

It’s a carbon copy forecast Tuesday.  Expect locally dense fog in the morning followed by hazy, humid conditions and heavy afternoon storms.  Be on the look out for more heavy rain and highs in the upper 80s with heat indices

RPM2 RPM3 RPM4 TUESDAY PLANNER

Heat indices tomorrow will again surge into the 90s and the humid conditions fill up much of the Skytrak13 7 day forecast.

7DAY

There is a daily chance of storms between now and Labor Day.  It doesn’t mean it will rain or storm all day long… though latest modeling does depict a soggy set up Sunday.  It’s still far away and much can change between now and then.  It’s a perfect forecast if you felt as though we missed out this summer.  Enjoy – Sean Ash

Fog, Heat And Storms

Posted By · August 25, 2014 at 3:12 am

It is a muggy, warm start to the day and in many areas we’re seeing fog this morning.  This will all be followed by hazy sunshine and a slight storm chance tonight.  Highs will top out at 89 but some towns could see 90 for the first time this year.  Try and stay cool, because heat indices will be in the 90s to near 100 in spots.

Better storm chances arrive Monday night into Tuesday.  There is the potential for multiple rounds of storms Tuesday… both in the early morning and afternoon.  Another 1-3″+ rainfall is possible for some depending on the track and coverage of storms.  This marks another unsettled stretch that brings daily chances of heavy storms as Indiana remains on the edge of the hot dome.

The rest of the week looks almost like Central Florida with daily chances for thunderstorms and highs in the mid 80s. We’ll keep you covered during the day on WTHR TV and WTHR.com.

Another Week With Heavy Storms Possible

Posted By · August 24, 2014 at 5:17 pm

We continue to deal with an oppressive Muggy Meter in central Indiana with tropical dew points locked into the 70s.  This is makes it feel uncomfortable, and requires frequent breaks if you’re outside for a lengthy period of time.

MUGGY METER

Another byproduct of the recent wet stretch and humid air is a very high pollen count… mainly consisting of ragweed and grasses.  If you’re like myself, you’ve probably noticed an increase in sniffles and sneezing.  It’s no fun and likely won’t get better anytime soon.

POLLEN

Though high temperatures technically remained below 90 degrees Sunday… heat indices climbed into the 90s and even lower 100s in southern Indiana.

HEATINDEX

The core of the hot dome/heat ridge remains displaced to our west.  This is where Heat Advisories/Excessive Heat Warnings are up and where temperatures are daily in the mid to upper 90s.

OHIO VALLEY TEMPS

This Evening: There isn’t an atmospheric trigger around to create widespread storms like Saturday evening.  But isolated showers and storms remain possible while the sun is up.  It should be noted that anything that can develop will have heavy rain potential with a highly “juicy” atmosphere in place.

EVENING PLANNER

RPM

Tomorrow: Monday will be similar to today.  Areas of dense fog in the morning followed by hazy sunshine and a slight storm chance in the afternoon.  Highs will near 90 and heat indices will be in the 90s.

RPM2 RPM3

Remember that while isolated, locally heavy rain is very much in play Monday afternoon if anything can develop.

MONDAY PLANNER

It’s been 348 days since Indianapolis’ last official 90 degree day.  That’s the 5th longest streak on record and Monday may be our best chance this week.

LAST 90 DEGREE DAY

Storm chances ramp up again Tuesday with the potential for multiple rounds of storms… both in the early morning and afternoon.

RPM4 RPM5 RPM6

Another 1-3″+ rainfall is possible for some depending on the track and coverage of storms.  This marks another unsettled stretch that brings daily chances of heavy storms as Indiana remains on the edge of the hot dome.  This is something in meteorology we call the “Ring of Fire.”

RAIN POTENTIAL

Warm, humid conditions look to prevail into the Labor Day weekend.  Have a great evening – Sean Ash

Sultry Sunday, Cooler by end of Work Week

Posted By · August 24, 2014 at 7:07 am

The very warm, moist air mass will remain in place for the next few days before more storms and cooler temperatures arrive.

We are still tracking our first 90 degree day for 2014.  Yesterday, temperatures climbed to 88 degrees.  We do have a shot at hitting 90 today but better chances arrive on Monday and Tuesday.

It will be a hot and sultry, partly sunny day with a slight chance of an isolated storm this afternoon through early evening.   Afternoon highs will climb into the upper 80s with heat indices making it feel like it’s in the low 90s.

sunday   heat indices

It will be partly cloudy and muggy tonight with lows in the low 70s.

The hottest stretch of the summer continues on Monday with mostly sunny skies and highs around 90 degrees.  Once again, heat indices will be in the low to mid 90s.
Tuesday will be much of the same with a chance of storms pushing in by late day.
An unsettled pattern returns Wednesday through Friday with daily chances of thunderstorms.

The average high for this time of year is 84 degrees.  Temperatures will cool below normal by Friday, only climbing to near 80 degrees.

Right now, next weekend looks cooler and dry.

Chance of More Storms Today

Posted By · August 23, 2014 at 7:31 am

The hottest stretch of 2014 continues this weekend.  We still have yet to reach the 90 degree mark but there are two good chances over the next few days.

We are starting off with foggy conditions over central Indiana this morning, thanks to the rain from yesterday and the light winds this morning.  Visibilities will improve by 10am.  It will be hot, hazy and humid today with a few scattered thunderstorms this afternoon.  Temperatures will climb into the upper 80s with heat indices in the mid 90s.

saturday pattern

A few more isolated storms will be likely this evening with mostly cloudy skies.  It will be a warm and muggy overnight with temperatures only falling into the low 70s.

We have a chance to hit 90 degrees on Sunday with partly sunny skies and light breezes out of the southeast.  The jet stream will shift farther north on Sunday, allowing more heat and humidity to push into Central Indiana.

Weekend Forecast

Posted By · August 22, 2014 at 4:32 pm

Doppler Radar estimates 9+inches of rain fell across Blackford county.  Flooding is still a big concern for parts of central Indiana especially northeast of Indianapolis.

There is some good news.  The heavy rain is gone for now.  Expect a warm and muggy Friday evening, with temperatures in the 80s through about 10pm.  A couple of showers are possible, but we are not forecasting widespread heavy rain.

rpm1 rpm2

Saturday will start dry, with morning temperatures in the lower 70s.  There will be more clouds than sun and a chance for a few afternoon and evening storms.  Due to the clouds and the threat for more rain, I think we miss 90 degrees.  Forecast highs are in the range of 85-90, but the 90s will only happen where there is more sun.

rpm3 rpm4 rpm5

AFTERNOON PLANNER HIGHS

I think we miss 90 degrees on Saturday due to too many clouds.  We missed 90 degrees this week, due to clouds and rain.  Our last 90 degree day was September 11, 2013.

event

A few storms are possible later Tuesday, with highs in the middle and upper 80s.

A developing weather system will bring more rain chances Wednesday and Thursday.  We get a break from the higher heat and humidity by Friday of next week.

More Storms, More Heat, More Humidity

Posted By · August 22, 2014 at 12:39 pm

Showers and thunderstorms will taper off by early afternoon.  Flash Flood Warnings are in effect for Delaware and Randolph counties until 3:30pm this afternoon.  Flood Warnings are in effect for Grant, Miami, Wabash, Delaware and Randolph counties through most of the weekend.  Be careful of flooded roadways.  Don’t attempt to drive through flooded roads.

flood warnings
It will be a cloudy, sticky and warm day with temperatures climbing into the mid 80s.  Heat indices will climb into the upper 80s today.

More thunderstorms will be possible this evening, bringing heavy downpours to central Indiana.  If  you are heading out to Operation Football tonight or any other outdoor activity, make sure you have your SkyTrak13 Weather app with you.  Temperatures will only fall into the low 70s with patchy fog likely Saturday morning.

The unsettled weather pattern will continue on Saturday with a chance of more scattered thunderstorms.  It will be a hot and humid day with temperatures soaring into the upper 80s.  Heat indices will make it feel like it’s in the mid 90s.

It will be partly sunny, hot and steamy Sunday too, with highs near 90 degrees.

The heat and humidity stick around into the work week with more storms arriving mid week.  This will bring cooler conditions to Central Indiana.
