Hot, dry pattern - Live Doppler 13 Blog

We are settled into a dry pattern as an upper level ridge settles into the eastern US.

That means lots of sunshine for today with slightly above average temperatures.

A high forecast of 84 today is 7° above average yet will be the "coolest" of the week.

With a clear sky overnight and a relatively dry air mass situated through Indiana, the warmth with quickly be released back into the atmosphere allowing for cooler overnight temps. Many spots start Wednesday off in the 50s.

Wednesday will be another mainly sunny and warm day.

One thing that we won't be dealing with is a high humidity as the dry air remains in place. Keep in mind though, dry air tends to heat quicker than moist air so temperatures will quickly recover to the mid 80s.

High temps Wednesday will range from the low to upper 80s through the state.

The humidity will slowly move back in starting on Thursday and it will become slightly more muggy through the end of the week.

Temperatures will also increase starting on Thursday with high temps nearing the 90 degree mark through Saturday.

Our next weather system arrives on Sunday and will bring the next best chance of showers and storms which will hinder our high temps to the lower 80s.

That rain chance Sunday could force the roof to be closed for the Colts home opener against the Falcons.

Tailgate town looks to be mainly dry for now though -- temperatures in the lower 80s in the afternoon.



Dry, Warm September Continues

After a couple of days of highs in the lower 80s... temperatures rebounded quickly Monday afternoon with highs near 90 and heat indices in the 90s.

Monday is the muggiest air until Friday... as a east-northeast wind pushes in much lower dewpoints by Wednesday morning.

The drier air leads to big temperature swings from comfortable overnight lows and warm afternoon highs. We're expecting above average highs into this weekend.

We're also forecasting little to non-existent rain chances until a front approaches Sunday.

Between now and then the dry month continues and the latest drought monitor index puts some areas of Central Indiana in moderately dry conditions.

Rain deficits in Indy this month are nearing two inches below normal in what's been the driest September 1st-16th since 2005... and 7th driest on record during that time.

Dry soil aids in boosting temperatures in this type of pattern and it's conceivable we tack on a few more 90° days between now and early next week.

Rain chances are slim to none until Sunday when a cold front arrives. For now we're forecasting scattered showers and storm... but will fine-tune in the coming days. It does appear this front snaps the warmer than normal pattern.

We stay mainly dry this afternoon but with scattered clouds. Warmer and muggy with highs in the upper 80s and heat indices in the 90-95° range.

The Grill Cast is looking great for this evening with temperatures falling back into the lower 80s through 8pm.

With a mainly clear sky overnight, temperatures will be slightly cooler than this morning. Overnight lows range from 62-66° through central Indiana.

Tuesday is looking to be the coolest of the week with highs in the mid 80s. That is still about 5° above normal for this time of year. Plenty of sunshine expected as well.

We're in the final countdown at summer winds down -- fall officially begins at 3:50 a.m. EDT on Monday, September 23.

While we will be officially into the new season -- the fall color change usually doesn't occur in central Indiana until late October, early November. The following are average dates of fall foliage.

By Wednesday, daytime highs return to the mid to upper 80s with a stretch of potentially 90°+ days lasting through the start of next weekend.

Month-to-date, Indianapolis is now trending the 7th driest September on record only having officially picked up 0.01" of rainfall since the start of the month and more than -1.5" compared to the average rainfall for this point of September.

We could certainly use to rain but it doesn't appear the next best chance is until next Sunday.

This rain chance will also bring a breakdown of the heat with highs back in the lower 80s Sunday and potentially in the upper 70s by next Monday.

A cold front will situate itself south of central Indiana through Monday keeping the forecast mainly dry but with scattered clouds.

Warmer and muggy with highs in the upper 80s and heat indices in the 90-95° range.

A ridge of high pressure will build in through the region for most of the week keeping it mainly dry and unseasonably warm. Tuesday is looking to be the coolest of the week with highs in the mid 80s.

By Wednesday, daytime highs will be near 90 with a stretch of potentially 90°+ days lasting through the start of next weekend.

We've already achieved more 90°+ day in Indianapolis this year as compared to the average amount -- with a few more still in the forecast for later this week.

The Climate Prediction Center's long range forecast through September 25th keeps a 60% chance of above average temperatures in play for central Indiana.

In addition to the heat -- we could use some rain.

Month-to-date, Indianapolis is now trending the 7th driest September on record only having officially picked up 0.01" of rainfall since the start of the month and -1.55" compared to the average rainfall for this point of September.

It doesn't appear the next best chance of rain returns until next Sunday. The pattern will be relatively dry until then.

A decaying storm complex moving in from the northwest will keep stray showers in the forecast for areas mainly north of I-70 through the early afternoon. Relatively dry air and lack of lift should keep many places dry today.

Rain chances dry up through the afternoon with more sunshine possible the farther south you go in central Indiana.

Highs likely don't reach 90° this afternoon for the Indy metro, but we do expect a quick warm-up after morning clouds thin out and highs reach the mid to upper 80s - a good 10° above average.

The heat settles in for much of next week as an upper high sprawls out across the Ohio Valley.

This means above average temperatures and mainly dry conditions.

Look for highs in the upper 80s near 90, again, about 10° above average for this time of year for Monday.

Tuesday will be the "coolest" day of the week with highs in the mid 80s with temperatures rebounding back into the 90s starting Thursday.

That pattern keeps central Indiana relatively dry with limited rain chances.

Month-to-date, Indianapolis is now trending toward the 11th driest September on record, only having officially picked up 0.01" of rainfall since the start of the month and -1.3" compared to the average rainfall.



Above Average Warmth Continues

A warm, but noticeably less humid Saturday in Central Indiana with a blanket of sun and highs in the 80s.

Dewpoints remain in the 50s so the Muggy Meter stays comfortable this evening and overnight. This well be key to a pleasant cool down after sunset as lows drop back into the 50s/lower 60s Sunday morning.

This relatively drier air also plays a role in eating-away at an approaching remnant storm complex early Sunday too. Though we're likely going to have its leftover cloud cover into midday Sunday... there's only a slight chance (for now) of raindrops impacting areas north-northwest of the Indy metro area.

Many places stay dry on Sunday but you'll also notice warmer, more humid air arriving by the afternoon. Clouds thin Sunday afternoon and temperatures quickly warm into the mid/upper 80s.

If you're not a fan of the above normal temperatures... then you're not going to like the weather around here next week. We're on tap for highs to daily be in the upper 80s/lower 90s with mainly sunny conditions.

This continues what's been a much drier and warmer than average September. Enjoy your evening and check the radar and forecast Sunday morning for any potential changes regarding the aforementioned storm complex.

After a four-day stretch 90°+ days, we will get a brief break from the high heat and humidity today with highs in the low to mid 80s.

The sky remains clear with plenty of sunshine through the day. Temperatures drop back into the 70s around sunset.

Expect mostly clear, calm, and comfortable conditions overnight with lows falling to near 60.

Don't shut those air conditioners off for the season just yet though. Winds shift shift back from the south for Sunday and the heat resumes.

The day looks mainly dry with the exception of a quick round of stray showers in the morning.

Mainly sunny and breezy with southerly gusts to 20 mph Sunday afternoon.

High temperatures tomorrow will once again push the 90° mark through central Indiana.

The heat settles in for much of next week with highs in the upper 80s -- about 10° above average for this time of year.

The pattern stays relatively dry with limited rain chances as well.



Friday the 13th Harvest Moon - Live Doppler 13 Weather Blog

Angela Buchman

There will be something special in the sky Friday evening and Friday night. It is the harvest moon. A harvest moon isn't that special. It is the full moon that happens on a date that is near the start of fall. The harvest moon that happens this year happens on Friday the 13th. The last time that happened was about 20 years ago. It won't happen again until 2049.

Sometimes the harvest moon is also a supermoon. That happens when it is closer to the earth. This year won't be a super moon but a micromoon. This happens when it is full at the most distant part in orbit. We are forecasting some storms for Friday afternoon, but the skies should clear in time for viewing Friday evening and Friday night. Enjoy.



Sticky September - Live Doppler 13 Blog

The September stickiness continues again today with temperatures soaring back into the upper 80s to near 90 degrees. Today could mark the third 90 plus degree day this month. The 90 plus degree September average for Indianapolis is 2.3 days. The most 90 plus degree days were 12 days recorded in 1891 and 1897.

It will be hazy and humid with a few isolated thunderstorms possible. Heat indices will be in the mid 90s.

It will be a warm and muggy evening with temperatures only falling into the low 70s.

A cold front will arrive on Friday. Widely scattered thunderstorms will be possible, mainly afternoon into the early evening. A few strong to severe storms will be possible.

Afternoon highs will be in the mid 80s.

The weekend will still be warm but not as humid. Saturday will be mostly sunny with highs in the mid 80s.

A few showers and thunderstorms are possible by Sunday evening with highs in the upper 80s.

Temperatures heat back up again early next week with highs in the low 90s.



Hot, Hot, And Hot

For the 19th day this year Indianapolis hit 90°. In fact, afternoon temperatures were closer to daily record high levels than average.

In addition... the an oppressive Muggy Meter made it feel more like 95 to near 100° due to dewpoints near 70°.

Our weather pattern and associated air mass does not change much the next 48 hours. That means you can expect at least two more 90°+ days this week and possibly a third on Friday depending on the time of a cool front.

That front is our next best chance of rain, but even so our odds of precipitation right now are only at 40%

Less humid air moves in behind this front for the weekend with highs in the 80s under a blanket of sun.

Relief from the high heat appears to be brief with long-range guidance continuing to support above average temperatures... possibly 90°+ again. What could potentially alter that would be any system(s) from the Gulf of Mexico.



Heat dome builds - Live Doppler 13 Blog

The heat and humidity return to central Indiana today as a dome of high pressure across the southeastern U.S. builds in.

This will bring temperatures that top out 10-15° above average through much of the week.

Factoring in the increased moisture into the air -- it'll feel more like that mid to upper 90s with the heat index this afternoon.

Hazy, hot, humid conditions continue through the week. There is a slight chance of stray pop-up storms on Wednesday as a humid air mass settles in and a boundary sets up to the north.

Highs on Wednesday top out in the upper 80s/lower 90s with heat indices again in the mid to upper 90s.

The tropical air mass continues into Friday before a cold front arrives later in the day. High temps will still be in the upper 80s.

A few thunderstorms are possible along this front Friday afternoon and evening -- be aware for Friday evening Operation Football or any outdoor plans.

Next weekend looks more pleasant with highs back in the low to mid 80s with mainly clear skies.



September Sizzle

Thanks to sunshine and a the passage of a warm front, it's noticeably warmer and more humid in Central Indiana.

Temperatures easily climbed into the 80s... a good 10-15° warmer than Sunday afternoon.

This is just the beginning of a mult-day stretch of above average high temperatures that lingers into Friday afternoon. This is quite the contrast to tempeatures over the past week.

The Muggy Meter also ranges from uncomfortable to oppressive in the coming days too as dewpoints near 70°.

As a result, heat indices peak-out near 100 at times and this air mass is evident to our southwest already.

Rain chances remain slim to none with our next best shot arriving with a cool front Friday afternoon/evening.

This front brings some relief this upcoming weekend before a resurgence of above normal warmth looking likely next week.

90° days are not uncommon in September and in fact Indianapolis had 8 such days last September.
