Heavy Rain, Gusty Wind, And Near-Record Warmth

Central Indiana embarks on a wet 48 hours beginning this evening. Rain expands over the state between now and midnight with rumbles of thunder likely heading into the Friday morning commute... possibly some areas of small hail too.

Rain amounts tonight range from a quarter-inch to locally 1" in heavier bands. Though wind gusts likely exceed 35-40 mph at times, we don't expect severe weather tonight... but thunder and downpours may either wake you or keep you awake.

Temperatures remain steady in the upper 40s to near 50° (30° above average) and set the stage for near-record warmth Friday. Despite clouds, fog, mist, and occasional rain... we're forecasting highs to near 60° late in the day. That will be 25° above the daily average high and near the daily record 62° set in 1975.

Wind remains gusty Friday and pumps unseasonably humid air into the state. This highly moist air mass interacts with an intensifying low pressure system and frontal boundary to generate widespread heavy rain.

Many areas get 2"-4" rainfall by Sunday morning with locally higher 5"+ amounts targeting northwestern Indiana. Low-land flooding is likely and precautions should be made now if you live in areas that flood during heavy rain events.

As a result, a Flood Watch goes into effect Friday 7 PM to Saturday 7 PM.

In addition to heavy rain, severe wind gusts and/or tornadoes can not be ruled-out. The wind field over Central Indiana Saturday afternoon and evening could be labeled extreme. It's uncertain if any of the low-level jet can mix down to the surface, but if it does the possibility of gusts over 60 mph climbs. Be Weather Aware and have a way to get warnings if needed.
