A wind shift early Thursday and we replace the tropical air with a much more comfortable brand of air as we end the work week.  Wednesday afternoon's dew point reached 75° in Indianapolis, as high as it ever gets in the summer months and combined to produce a heat index of 99°.  The dew point is dropping Thursday and it will lead to a much more comfortable night.  Temperatures will lower to near 60 degrees early Friday morning.  The humidity will remain low through Sunday afternoon!

With over 3" of rain officially for the city and some areas nearby receiving over 5" in the past few days we could use some dry time.  June 2016 to date ranks among the wettest 21% on record.  To date we are running 1.00" above normal.

14 day rainfall June 16

Estimated two week rainfall ending June 15th


Rain chances are not in the forecast again until a cold front approaches next Tuesday.  Great news for many that are cleaning up after the recent heavy rain.


Over a dozen states Thursday afternoon are under some form of a heat advisory or warning.  Temperatures are hitting the century mark again across parts of Kansas, Missouri, Nebraska and Iowa.  St. Louis at 5 PM Thursday was nearing a record of 100°.  The heat will stay west entering the weekend but all indications are that a surge in the heat and humidity will arrive here to open next week.

90° temperatures return as early as Sunday but likely to reach the low to mid 90s by Monday.  Along with the heat Monday comes a big jump in the humidity.  Enjoy the mild air and give the A/C a break overnight Thursday, Friday and Saturday nights.
