Freezing rain (initially may be mixed with sleet) overspreads central Indiana between 1p-3p. We advise to get any and all travel done prior to 1p and plan to stay in…

Just a quick update to give you some fresh thoughts on the next winter storm that will impact central Indiana.
We bracket the hours of 1p-3p for the onset of sleet and freezing rain across central Indiana.
Coverage and intensity of freezing rain will increase as we progress through the evening hours. We suggest hunkering down at home (or at a loved ones home) for the Colts game, as roadways will likely become hazardous during the game.
Early data hot off the press this evening is suggesting Ice Storm Warning criteria (freezing rain amounts of 0.25″, or greater) is met through the heart of central Indiana.
A fresh push of cold, arctic, air will ooze back into central Indiana during the day Monday. We think overnight lows head back into the single digits Tuesday morning and below zero Wednesday morning. Needless to say, should power outages take place, a nasty situation will develop with the new push of cold air.
Please stay tuned to your favorite media or means of obtaining weather information, as this will be an impactful event for central Indiana tomorrow afternoon into Monday.

Highlights:
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.

Busy times continue in the good ole weather office as we get set to deal with yet another winter storm during the upcoming weekend.
First, we’ll deal with more below zero temperatures tonight and Saturday morning as overnight lows bottom out between 5 and 10 degrees below zero tonight area-wide. Wind chill values, of course, will be even colder (-15 to -25). Dangerous cold continues with considerable blowing and drifting in the open country. Saturday will be the “calm before the storm” with unseasonably cold conditions continuing, but with lighter winds and sunshine.
Clouds will increase Saturday night into Sunday and we’ll begin to introduce precipitation into your forecast as early as Sunday afternoon (not a bad day for two classic back-to-back playoff games if you ask me). Here’s our best idea of what you can expect statewide after reviewing all guidance today:
Some initial thinking would place the following numbers (a bit early to be too specific), and we caution this will have to be fine tuned as we move forward.
Snow accumulation of 2″-4″ across north-central Indiana, particularly just north of Indianapolis. In the “mainly snow” zone, expect amounts of 3″-6″. Ice storm criteria accumulation of freezing rain is possible (0.25″, or greater) across central Indiana, as well. South of the city, early ideas suggest roughly 1″-2″ of snow and glaze potential closer to that potentially damaging 0.25″ amount. Again, we state that these numbers are very early ideas and will have to be fine tuned.
Precipitation should initially overspread central Indiana Sunday afternoon in the form of sleet and snow (more sleet south-central, more snow north-central) before transitioning to more of a sleet and freezing rain event. Finally, we anticipate the wintry mixture of precipitation to end as snow before moving out Monday morning. Timing and duration of precipitation types will obviously determine how much ice and snow a given location sees.
Another big item we want to be sure to mention is that yet ANOTHER push of bitter arctic air will invade behind this storm and set the stage for another dangerously cold period Tuesday into Wednesday (back below zero we go)!
Stay tuned as we continue to fine tune the forecast over the weekend!

January is off to a frigid start. After a mild December, January is certainly reminding folks that there’s a lot of winter in this pattern. Precipitation is running above normal…

Ready For More Wind And Snow?! The day will dawn with sunshine and downright frigid temperatures. Some numbers as of 7am include the following:
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 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.

The snow storm that moved through northern and central Indiana deposited half a foot, or more, of “champaign powder” for the northern Indianapolis suburbs overnight into this morning with amounts tapering dramatically further south.
Left behind will be a day that will provide “decent” conditions for digging out. We’ll introduce sunshine and temperatures will be downright “balmy” when compared to what blows into town tonight. Though well below average, today’s high in the lower 20s will feel like a heat wave when we look ahead to the upcoming couple days.
Things begin to change in a big way tonight as arctic air invades. Additionally, winds will increase and lead to all sorts of blowing and drifting concerns. This dry/ powdery snow will be blown about quite easily and lead to reduced visibilities tonight and Wednesday along with significant drifting. Some additional light snow will accompany the initial arctic push tonight.
Note the temperature crash that’s coming:
Temperatures fall into the single digits by 10pm.
Wednesday morning lows.
Modeled forecast lows Thursday morning.
Officially we forecast the following:
* Wind chill values will fall to 25 to 30 degrees below zero Wednesday into Thursday morning.
