“Relaxation” Of The Bitterly Cold Pattern…That forecast package title sure wouldn’t suffice describing the weather outside this morning. It’s a downright bitter feel, including below zero temperatures throughout north-central Indiana. Patchy freezing fog and scattered flurries are also with us this morning. With some sunshine later, we’ll “warm” into the lower 20s this afternoon. A few flurries may fly tonight as a weak disturbance moves through the region.
Sunshine will be with us to wrap up the work week along with slowly moderating temperatures. Average highs this time of the year are in the middle 30s so we’ll be closer to average Thursday and Friday- though it’ll likely feel much warmer simply based off just how cold it’s been as of late. Gusty southwest winds will blow milder air in here briefly Saturday as temperatures climb into the middle 40s.
A cold front will sweep the state Sunday morning with a possible rain shower that’ll quickly transition to scattered snow showers as the colder air filters back into the region. The next storm system of note arrives early next week.
Upcoming 7-day Precipitation Forecast:

Sunny Today; Next Winter Storm Arrives Tomorrow…While it’s always nice to see the sun, it won’t do much to warm temperatures this afternoon. Another frigid morning (all reporting sites across central Indiana went below zero again this morning) will only “warm” into the upper teens this afternoon.
The big focus of this forecast package has to do with what lies ahead Sunday afternoon through Monday morning. Model data continues to suggest central Indiana deals with another winter storm. A model average puts down between 0.30″ to 0.50″ (liquid equivalent). On a standard 10:1 ratio, that would be between 3-5″ of snow, and if that 0.30″-0.50″ all fell in the form of freezing rain we would be looking at a damaging ice storm. As of now it appears as if we deal with the entire wintry precipitation gamut.
Moisture will surge north Sunday afternoon and we bracket the hours between 3-5p for the onset of wintry precipitation. Low pressure will organize along the Gulf Coast and move northeast into the Tennessee Valley Monday morning. At the same time, another dome of arctic high pressure will begin to sink south. The end result should be a wintry mix of sleet and freezing rain that eventually transitions to snow through the nighttime Sunday. Obviously timing that transition will be crucial in determining just how much snow and ice accumulates. As of now we’ll split the expected liquid equivalent down the middle and say 0.40″ falls across central Indiana. Of that 0.40″, 0.20″ may fall as freezing rain (glaze) and 0.20″ may fall as snow (which would stack up to a couple inches on the standard 10:1 ratio). Areas north of Indianapolis run a better chance of seeing the transition to snow faster while areas south of the city run a higher chance at accumulating more freezing rain. Stay tuned.
We go back into the deep freeze Tuesday-Wednesday and eye Thursday for the possibility of another storm system.

Ready For More Wind And Snow?! The day will dawn with sunshine and downright frigid temperatures. Some numbers as of 7am include the following:
- Zionsville: – 10
- Eagle Creek: – 6
- Indianapolis: – 6
- Frankfort: – 10
- Kokomo: – 8
Wind chill readings are obviously even colder (- 20 to -30). Clouds will quickly increase as we progress into the afternoon hours and snow won’t be far behind. We forecast a quick burst of heavier snow between 5-7p followed by snow showers through the evening. Most folks from Indianapolis and points north will accumulate around an inch of new snow this evening. Winds will also be very gusty and lead to all sorts of blowing and drifting concerns once again (of new snow and existing snow).
Temperatures will fall Friday and be in the single digits for most of the day before heading back below zero Friday evening/ Saturday morning. Welcome to the frozen tundra! 
Our next winter event of significance will press in Sunday. Clouds will lower and thicken through the day and snow should develop by evening. Light snow and potentially a wintry mix will continue Sunday night into the day Monday. Stay tuned!

Highlights:
- Dangerous Cold
- Blowing And Drifting Snow
- 2nd Shot of Arctic Air
- More Wintry Mischief Ahead
Dangerous Weather…Severely cold, arctic, air will continue to pour into the region today. Snow showers accompanied the arctic push during the early morning hours and a few flurries can be expected from time to time today (heavier lake effect snows northeast). Winds will be strong and gusty, including considerable blowing and drifting snow. Wind chill values will approach 30 degrees below zero this afternoon into Thursday morning. Needless to say, have a winter survival kit in your car if you must travel.
Additional impulses of energy will rotate through the region Thursday and Friday with periodic scattered snow shower potential Thursday afternoon into early Friday.
A second surge of arctic air will invade Friday night and Saturday morning and result in temperatures, yet again, below zero.
As we move forward, all eyes will turn to the potential of new “wintry fun and games” late in the weekend into early next week.
