As advertised, it's been a wet Monday in Central Indiana with many areas near/above a half-inch rainfall already.
The steadiest and heaviest rain axis pushes east of Indy heading into midday with scattered rain lingering well into the evening. The "lull" in widespread downpours allows temperatures to creep into the upper 60s.
While atmospheric instability is minimized from cloud cover, rain, and little heating... there is more then enough wind shear to warrant the possibility of localized severe storms later today.
We'll need to monitor scattered downpours/storms that develop along and ahead of an approaching cold front between 3 - 8 PM. These cells will have the potential to rotate within the highly sheared environment. Admittedly it's a rather low chance but needs to be monitored in the event conditions can be maximized along the front.
Windy conditions can be expected even outside of storms today... as an strengthening low pressure spins to our northwest. This creates a tight pressure gradient wind field in Central Indiana to produce gusts over 30 mph at times.
In fact, gusty wind is likely the next 24-30 hours as this low moves across the Great Lakes. The wind brings in colder air overnight into Tuesday in the wake of the front passing through this evening. Lows return to the 40s Tuesday morning and highs likely stay below 60° Tuesday afternoon with blustery conditions.
Wednesday remains the Pick-Of-The-Week with sunshine and pleasant highs in the mid-60s. Temperatures briefly warm into the 60s Thursday before the next cold front arrives with shower chances and colder air Thursday night into Friday.
There remains mixed signals for the upcoming weekend... specifically Sunday. Some solutions remain completely dry and pleasant, while others paint a wet picture with a low from the south. We'll wait and watch but at least the possibilty of showers Sunday.
