The Heat (And Humidity) Is On This Indy 500; Memorial Day Weekend…

As we grow closer to the big Indy 500 and Memorial Day weekend, forecast guidance continues to back away from what at one point looked like a rather unsettled weekend.  Instead, it appears as if heat and humidity will grab the headlines.  While we can’t rule out an isolated to widely scattered thunderstorm (best chances of that coming Sunday and Monday), most will remain rain and storm free this weekend.  Even if you’re one of the “lucky ones” to get under a storm, it’ll pass quickly and sunshine will return.

While “tropical mischief” approaches the central Gulf Coast this weekend, an upper level ridge will dominate our weather.  This supports the drier trend the models are now going to and also will help boost temperatures.  We forecast highs at or around the 90° mark Saturday through Memorial Day- well above the average high of 78°.

The other big story, especially for those planning to attend the race, will be increasing humidity over the weekend.  Forecast dew points will approach and exceed the 70° mark Sunday afternoon, providing a very tropical feel to the air.

Timing Out Storm Chances Tonight…

We continue to monitor things closely for the potential of strong to severe thunderstorms this evening into tonight.  As of this morning, we still believe greatest threats of severe weather…

Increasingly Hot And Humid…

Highlights:

  • Increasingly hot and humid
  • Isolated storm coverage becomes more widespread
  • Relief next week

Air You Can Wear…The big weather story will be the increasingly hot and humid feel as we progress through the week and on into the weekend.  The combination of dew points in the 70s and wet soils across the state should “beat back” the heat from getting to where it otherwise could (mid-upper 90s), but it’ll feel oppressive, nonetheless.  Plan to hydrate and wear cool, lightweight clothing if you plan to be outdoors for any length of time.

While we can’t completely rule out a renegade storm through Friday, most neighborhoods will remain free of any rain through the remainder of the work week.  Better coverage of showers and thunderstorms will increase over the weekend into early next week as the transition from hot, humid weather begins to give way to a more pleasant feel.

Afternoon And Evening Rumbles…

Highlights:

  • T-storms arrive this afternoon
  • Heating up this week
  • Stormy periods late-week

Pleasant Start; Stormy Finish…After we got rid of the low level clouds and fog Saturday, it turned out to be a gorgeous day!  The balance of our Sunday will also be very pleasant, but a frontal boundary will push through the state this evening and will be sufficient enough to kick up a line of showers and thunderstorms that will impact central IN this afternoon and evening.  One or two of the storms could reach severe levels (large hail and damaging wind).

As we look forward, the big weather story this week will be the increasingly hot and muggy feel by late-week.  Factor in that highs will approach 90° the second half of the week, along with dew points exceeding 70° and the stage will be set for a truly “oppressive” feel.  Prepare to sweat.

Along with the increasingly heat and humidity, we’ll also note an increase in overall coverage of showers and thunderstorms through the late-week stretch.  Individual disturbances will create periods of more widespread storms and with such a moisture rich air mass in place, expect periods of locally heavy rainfall.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
