ONE MORE COMFORTABLE NIGHT
The reprieve from oppressive heat and humidity will end abruptly Sunday afternoon as southwest winds return early in the day. All of central Indiana enjoyed a great open to the weekend as early morning temps Saturday dipped to the lowest levels in 3 weeks. Officially the city went to 61° - coolest since late June. While the afternoon high Saturday reached 91° (the 34th of the season 2x the norm for an entire year) it was a dry heat. Relative humidity only peaked around 30% making it much more comfortable.
Comfortable temps away from the city early Saturday included 57° at Columbus and 55° at both Bloomington and Muncie. Zionsville came in as the coolest low in the state at 54°
Temps Sunday morning will not be as cool…lows in the city will dip into the upper 60’s and will range from 5 to 9 degrees warmer than Saturday morning.
HEAT AND HUMIDITY SURGE
Middle 90’s are back Sunday along with rising humidity. The hot dome in the central U.S. is migrating back to the east starting Sunday – along with 100° temps, topical humidity will surge creating afternoon heat index of near 105°.
RIM OF FIRE PATTERN
Active, Gusty and possibly severe storm clusters are possible as we get into the work week. The flow around the intense hot dome will be pointed at central Indiana from the northwest. Thunderstorm clusters are expected to develop in this channel of upper air around the perimeter of the hot dome. Storms may bring prolific rain – lightning and strong winds…question is where and when. Only time will tell. Stay tuned to later forecasts this week.
