Indy Finally Hits 90 Degrees And Heavy Evening Storms

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.

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

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
