 Despite sunshine this afternoon, high temperatures struggled to reach above 50 degrees.

Overnight, temperatures will quickly drop back into the 30s. Lows will fall into a 34 to 38 degree range across most of Central Indiana.

Here is the tale of the temps for tonight:

AVERAGE LOW: 46 degrees

PREDICTED LOW: 36 degrees

RECORD LOW: 31 degrees

 Let’s talk.

There are two interesting meteorological possibilities to keep an eye on in the short term.

First, a few snowflakes may appear within an area of departing rain showers tonight. Keep your eyes open!

The next feature to watch for is frost. A freeze watch is effect from late Tuesday night through Wednesday morning. I helped my wife move plants onto our screened in porch this afternoon.

A low pressure will approach from the southwest and rain chances will return tonight. The showers will be on and off on Monday. Temperatures will be cool with highs only in the mid 50s.

Dry conditions are expected Tuesday through Thursday. A warming trend will occur through the period, with highs in the 50s Tuesday, 60s Wednesday, and 70s on Thursday. Temperatures may fall near or below freezing by early Tuesday and Wednesday morning.
