Central Indiana barely made it to the freezing mark today in most locations but a brisk northwest wind has been providing a punishing blow all day long.  Winds have been coming in at 15-25 mph with gusts up to 30 mph. This means the bulk of our day has had wind chill values below the 20 degree mark!  That “chill” in the air is nowhere near done because winds aren’t forecasted to settle down until Sunday afternoon.

Wind Chill forecastSo here’s now the arctic blast breaks down.  Temperatures will fall into the mid to low teens tonight.  We are expecting a low of 13°F here in Indianapolis.  But once you add in our wind from the northwest at 5 to 10 mph overnight, it’s going to feel much colder.  Wind chill values will range from 0 to 9°F Sunday morning.

The spotty snow showers also end tonight as the clouds depart.  Skies will be mostly clear tonight and throughout the Sunday forecast.  Meteogram tomorrowBut don’t expect those rays of sunshine to help us out all that much on Sunday.  Temperatures will only increase to around 27° for our afternoon high.  Unfortunately, even with a light wind, it’s going to feel more like 20° or colder. A ridge of high pressure is sliding into the state on Sunday to solidify the cold air.

Temperatures improve a bit on Monday as our wind returns from the south on the back side of this arctic high pressure system.  This will help temperatures out a little bit as we return to 37° with mostly cloudy skies.  But a cold front is also projected to move into the state that night. This could produce some spotty snow showers as early as the evening drive and into Tuesday morning.  At this point, the event looks rather minor but we’ll keep an eye on it.  The next weather-talker of the week will be another quick shot of snow Wednesday night into Thursday morning.  But this is looking identical to the Tuesday system and quite minor.
