Some Severe Storms Possible Later Today

The Muggy Meter reaches oppressive humidity levels today as tropical moisture blankets Central Indiana.  This results in heat indices between 95 to 100 degrees combined with afternoon highs in the lower to mid 90s… good for Indy’s hottest day of the year if temperatures eclipse 92 degrees.

PLANNER HEAT INDEX FORECAST MUGGY METER

Though much of today is rain-free and hot, widely scattered storms develop this evening and some may reach severe limits before midnight.  Damaging wind and locally heavy rainfall are the main threats overnight.

SPC TODAY THREATS TONIGHT 7PM TODAY 10PM TODAY 11pm tonight 7AM TUESDAY

We’ll be north side of a cool front Tuesday which results in less humid air and a mainly sunny sky with seasonably warm highs in the mid-80s.  Based on lower humidity and abundant sunshine… tomorrow is our pick of the week to be outside.

TUESDAY JET STREAM

Modeled ingredients for mid-week advertise a heightened risk of severe weather and flash flooding Wednesday into Thursday.  Though uncertainty on track, intensity, and coverage remains… data sets suggest a swath 3″+ rainfall, widespread high wind (greater than 70mph) and some tornadoes could impact Central and Northern Indiana.

MID WEEK SPC

This could certainly change and as noted there’s a great deal on specifics at this time.  Please check back frequently for updated forecasts on what could be a high impact weather event – Sean Ash

Stormy Mid-Week Set Up

Happy Father’s Day! Seasonably hot conditions to wrap up the weekend with highs near 90 degrees and heat indices in the low to mid 90s.  Very isolated showers developed late this afternoon but they’ll quickly fade around sunset.

The bigger tomorrow will be the increasing Muggy Meter with oppressive levels of humidity.  A mid-week moisture surge brings a risk of flash flooding and severe storms.

Though isolated… a few strong or severe are in play Monday evening into predawn hours of Tuesday.  At this point much of Tuesday should be dry.

MONDAY 8PM MIDNIGHT

The weather pattern gets more interesting and complicated the middle of the week.  The upper level high pressure that kept us quiet this weekend is now beginning to move toward the southwestern U.S.

Eventually we’ll begin to see storms developing on the edge of its hot dome and get pushed southeastward into the Ohio Valley.  Riding the northwest flow aloft these storm clusters are known as “ridge riders” and the belt of storms around the upper ridge is sometimes referred to as “ring of fire.”

WED 1AM WED 7AM WED 2PM

At this point exact timing and location remain uncertain, but storms do appear likely both Wednesday and Thursday.  You’ll need to be weather aware with the potential for multiple rounds of heavy storms, flash flooding and severe weather.  Check back frequently for updates – Sean Ash

Hot Weekend Ahead

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.

TEMPS TONIGHT

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.

SATURDAY HIGHS SATURDAY AIR QUALITY

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.

AQI 2 AQI 3

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.

SUNDAY HIGHS SUNDAY HIGHS MONDAY

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.
