Hot Week Ahead

We’re turning up the burners this week, with little chance of rain and a high chance that Indianapolis hits 90° for the first time this season.  While many other cities around central Indiana have hit 90… it’s been nearly 11 months since Indy has officially been that hot.


Highs today climbed into the upper 80s.  With a few hours of sunlight left, it’s possible a stray shower or two may move through central Indiana.  Any showers that develop will be isolated, quick-moving to the NW and rapidly fade with the setting sun.


Lows bottom-out in the lower 70s, but another rapid warm up is on tap Monday.


Expect plenty of sunshine into midday, before the cumulus cloud field fires in the hot afternoon.  Highs flirt with 90° Monday afternoon… but I think there will be just enough cloud cover to keep highs slightly below 90. Regardless…high humidity will make it feel like the mid 90s!

Upper level high pressure strengthens over the Ohio Valley in the days to come.  The sinking air under this feature allows heat to build each day (compressional warming), puts the kibosh on precip chances due to sinking air, keeps the air stagnant which produces poor air quality by weeks end.  The humid air mass produces heat indices near 100° by mid-week.

A “ring” of rain and storms will fire around the edges of this summer high pressure ridge. 850MB_3

Long range model guidance suggests this high to break down next weekend as a front sneaks in from the north.  7day

For now our next “best” chance of precip is Friday night into Saturday.
