A shield of rain is lifting into central Indiana during the predawn hours and once it arrives, we can expect wet times to persist through the better part of our Tuesday.
This is all part of a surface low that will lift northeast out of the central Plains region (today) into the lower Great Lakes region (Thursday). In association with this low pressure system, a warm front will lift northeast across the region Wednesday. Eventually, a cold front will move from west to east and sweep the state Wednesday night and early Thursday.
As this all transpires, a steady “all day” soaker can be expected across the region today.
Heaviest rain will be confined to western and northwestern parts of the state where amounts of 2″+ can be expected by 7a Wednesday. For immediate central and eastern Indiana, amounts of 0.50″ to 1.25″ can be expected by Wednesday morning.
Precipitation will turn more “showery” in nature by Wednesday morning, but by this timeframe, all eyes will be turning to the potential of thunder Wednesday afternoon as just enough instability and cold air aloft combine. From the city, itself, and points north and east, the threat of a few stronger cells are present Wednesday afternoon (after lunchtime). With the ingredients in place, a few of these storms could produce hail as they race off to the northeast.
We’ll turn MUCH cooler Thursday and Friday with a few “nuisance” variety showers around, but compared to what we see today and Wednesday, these won’t be a big deal (just annoying ;-)).
The colder times continue into the weekend and early portions of the next week and with a fast northwesterly flow aloft, a couple of disturbances will likely deliver the potential of mixed rain/ snow showers Saturday and again Monday.
We still expect a hard freeze (25° to 30°) early next week for a good chunk of the region.
