Highlights:

• Tuesday Showers
• Weekend Snow For Some
• Pre-Christmas Wintry Event

Showers; Turning Colder Late…Showers will remain in our forecast today.  Most widespread rain will occur during the early morning hours, but we’ll maintain mention of light showers in our forecast even into the afternoon.  Winds will be gusty and help drive colder air into central Indiana later this evening.  We forecast nearly steady temperatures during the morning and afternoon hours before falling temperatures during the evening.

Dry, But Cold Mid Week…We’ll welcome a drier regime for the midweek period, along with partly to mostly cloudy skies and colder conditions.

Eyeing The Weekend…There’s not much change in our overall thinking of a potentially snowy first half of the weekend for some.  Monday featured run-to-run inconsistencies on our weekend storm system and we fully expect additional changes within the model data during the next couple of days.  In building our forecasts we factor in current data, but also rely on past data of storm tracks with similar setups.

At the end of the day (and despite model inconsistencies) we still think one area of low pressure heads northeast out of the mid MS River Valley into the Ohio Valley Friday night into Saturday.  A secondary area of low pressure is then expected to organize along the mid Atlantic coast Saturday afternoon.  Widespread light snow should build into the Ohio Valley Saturday with the above set up.  Exactly where heavier snow sets up is still up for much debate and will require fine tuning as we move forward.

Christmas Travelers Keep Close Tabs On The Forecast…After our first opportunity of potential wintry weather we’ll enjoy only a day or two of calmer weather in between storms.  Longer range data suggests we need to keep abreast of another winter event just prior to Christmas.
