Indianapolis started off mostly clear and on the chilly side early today, with temperatures near 56°F at the airport. The cool morning will not last. Highs are expected to climb into the upper 70s later today, but scattered showers and thunderstorms are likely to fire up this afternoon, right around the commute. Southwest winds will increase, and some spots could see brief gusts and pockets of heavy rain that cut visibility for short stretches.
Afternoon Commute
Forecasters put the best window for scattered showers and thunderstorms between about 2 p.m. and 5 p.m., with roughly a 60% chance of measurable rain. Most spots that get wet should see new rainfall totals between one tenth and one quarter of an inch. A few stronger cells could crank out wind gusts into the mid-20s, around 25 mph, along with brief, heavy downpours that can quickly slick up the roads. If you are running errands or heading home during that time, plan on slower travel and consider shifting any outdoor activities indoors if storms are nearby.
Wednesday Severe Threat
A more powerful system is set to move in on Wednesday. “Severe weather is likely on Wednesday,” according to NWS Indianapolis. Forecasters there warn that some storms could become severe and produce damaging straight-line winds, large hail and locally heavy rainfall. Forecast models show new rainfall amounts of 1 to 2 inches possible Wednesday night, and even outside of thunderstorms, wind gusts could approach 35 to 40 mph. If you have Wednesday evening plans, line up a backup option and keep an eye on any watches or warnings that may be issued later in the day.
How To Prepare
Basic storm prep goes a long way here. Move outdoor gatherings inside if you can hear thunder, and secure loose items such as tents or patio umbrellas that could turn into airborne projectiles in stronger gusts. Avoid driving through standing water, even if it looks shallow. For clear, state-issued guidance on thunderstorm safety, see Indiana DHS. Keep your phone charged and make sure you have at least one reliable way to receive weather warnings during the evening hours when heavier rain is possible.
