Rain chances remain low in central Indiana until next weekend. Isolated showers will quickly diminish this evening, as most backyards remain. Any heavy showers will be quick-moving and actually be tracking from east to west?!
This is called “retrograding” in meteorology, and is a result of an upper level low sitting over Evansville at this time. The counter-clockwise flow around this feature causes the precipitation to move east to west. This features weakens as upper level high pressure pancakes the Ohio Valley next week with descending air and building heat/humidity.
You’ll notice temperatures a bit warmer Sunday morning and afternoon. Lows will be near 70 and highs jump into the upper 80s… with only a slight late-day storm chance.
“Jungle”-like humidity returns as dewpoints jump into the oppressive range by Tuesday. The high heat/humidity combo produces heat indices in the upper 90s to near 100°.
The increased moisture will also keep overnight lows in the uncomfortable mid-70° range too. This will be our hottest stretch of days up to this point… with little rain for relief until next weekend.
Thanks for reading the blog and enjoy the rest of your weekend – Sean Ash
