It’s soggy now but it will be sunnier and warmer this time on Thursday.
INDIANAPOLIS — Forecasts for a wet Wednesday came true today and put a damper on Indy 500 practice at IMS. Although it looks like the widespread rain will end from west to east between now and 5 p.m., it’s uncertain if that will be enough time to dry out the track for today’s laps.
A calmer pattern is occurring overnight through Thursday morning for central Indiana. If Thursday is your day in IMS, you can expect mostly sunny skies with much warmer temperatures in the 80s. Temperatures and the wet meter will be noticeably higher tomorrow and will mark the start of the transition to summery heat. before the weekend.
An approaching warm front could trigger late afternoon storms over southern Indiana Thursday evening. Otherwise, expect plenty of dry weather on Thursday and Friday.
Friday remains the hottest day in our forecast with highs approaching 90 degrees and heat indices in the 90s as the wet meter becomes uncomfortable due to dew points in the over 65 degree range. Increasing low-level humidity, combined with growing instability, will make the atmosphere potentially volatile Friday evening.
The lack of lift keeps the chances of locally developing storms rather low at this point. However, it should be noted that any storm that develops in the modeled environment Friday afternoon/evening could rapidly strengthen and possibly become severe.
Guidance continues to slow as a cold front approaches during Indy 500 qualifying weekend in Indianapolis. This offers some hope that the rain/storms will be more scattered on Saturday, but also leaves the possibility that some showers may persist into Sunday morning. We’ll be fine-tuning the details in the coming days.
For now, Saturday looks much warmer (mid 80s) and wetter compared to a transition to much cooler (60s) with lingering clouds on Sunday.
