Very humid through Thursday night with more storms on the way

INDIANAPOLIS (WISH) — Scattered storms remain possible over the coming days. Some could be strong with heavy rain and gusty winds.  Less humid air returns for a few days starting Friday. 

TUESDAY EVENING/NIGHT:

The warm and humid air mass in place will support a continuing chance of showers & storms. Not everyone will get one… but if a storm forms it does have the potential to produce torrential rainfall, gusty winds, and perhaps some hail. Muggy lows in the lower 70s can be expected again. 

WEDNESDAY:

Some morning showers, storms, and clouds are possible but the afternoon is looking like it’ll be downright sultry with highs around 90 and heat indices near 100. Southwesterly breezes 10-20 will ease the burden a bit, but be sure to take extra steps to stay cool and hydrated.  The 30 year average date of the first 90 in Indianapolis is June 19th.  

Model data suggest a storm complex or two may graze northern Indiana in the later part of the afternoon and evening. It’s too early to tell if this will affect Central Indiana or not.  

WEDNESDAY NIGHT:

Warm and very humid conditions stick around. Look for another night with lows in the 70s.  Once again, some data suggest that a batch of gusty storms could roll across Northern Indiana.  That will be something to watch.

THURSDAY:

Warm, breezy, and very humid conditions hang around one more day.  Highs near 90 with heat indices around 100 appear likely.  While a shower or storm could pop anytime in the muggy air, most of the daylight hours should remain dry.  

A cold front will push in from the west during the evening and overnight hours.  This front will likely spark a line of strong to severe storms in Illinois.  These storms will move towards Central Indiana, but they may be in a weakening phase prior to arrival here. We’ll just have to watching things evolve.  The main severe threat in this setup would be damaging wind gusts it appears. 

FRIDAY:

After an early day rain & storm chance, the majority of the day should be pretty nice with partly cloudy skies, warm highs in the 80s, but lower humidity levels.  Any outdoor plans for Friday evening look great!

WEEKEND:

The pick day will be Saturday with plentiful sunshine, warmer temperatures, light winds, and reasonably dry air for a change.  Humidity increases again for Sunday and that will lead to another chance of scattered rain & storms.
