A cold front will move through the state Tuesday morning. Ahead of the front, temperatures will remain above normal.

Forecast high temperatures Monday.
Scattered showers and a few thunderstorms will be possible through the day Monday. A line of showers and thunderstorms is expected to move in to central Indiana early Tuesday morning ahead of the cold front.

While I am not expecting any severe thunderstorms, some of the storms may produce strong wind. I also suspect they will be big noise makers - meaning thunder and lightning may wake you up early Tuesday morning.
The rain early Tuesday may be heavy. Computer models project anywhere from 0.5" to over 1" of rain will fall Monday morning through Tuesday morning.

POTENTIAL FOR MARCH SNOW
One of the long range computer models has been hinting at a clipper diving down out of Canada later in the week. If this pans out, this may provide an opportunity for a little snow in the Midwest late Friday.

The same computer model suggests an area of low pressure developing to our southwest Friday and Saturday. If this pans out, moisture with the system may fall in the form of a rain/snow mix Saturday.
This is still quite a bit of uncertainty concerning next weekend's forecast, so be sure to check back for updates.
BY THE NUMBERS
While we are starting to make the turn for spring/summer, it is not unusual for snow to fall in central Indiana during March. 113 of the previous 131 months (86%) of March have had measurable snow in Indianapolis.
