The well-advertised one-two shot of bitterly cold arctic air will arrive mid week into the weekend. Dangerous wind chills and snow squalls will accompany each surge of arctic air. As…

Making Up For Lost Time…Many snow lovers out there have been disappointed by the lack of the white stuff winter to date. The cool thing is that the next 7-10 days (most likely longer) will offer up multiple opportunities to serve up accumulating snow.
First things first and that’s today- look for bright sunshine and a frosty start. Temperatures will “warm” to just under seasonal levels this afternoon. A fast moving storm system will scoot through here late tonight and Thursday morning with light rain, possibly transitioning to light snow showers before precipitation ends Tuesday (not a big deal). Far eastern areas may experience a brief period of light freezing rain or light sleet during the onset of precipitation, but things should switch over to light rain rather rapidly even for you. We’ll turn dry and cold to wrap up the work week.
All eyes are on the weekend as a storm system moves towards the region. We have a ways to go and we’ll have to fine tune the details over the next few days, but this has potential to be the most widespread significant wintry event of the season. Stay tuned. MUCH colder air will punch in here early next week and may set the stage for more wintry “mischief” by the middle of next week.
IU at Purdue: 9p tonight
Good news is that for those driving to West Lafayette tonight, you should be dealing with dry conditions. Precipitation chances will begin to go up as we near 11p, or after, for western portions of the state.

Slick Spots For Some; Accumulating Late Weekend Snow? A fast-moving disturbance will move through the region during the overnight/ wee morning hours and provide light rain for most of central Indiana, but areas just north of the city will deal with an icy mixture of sleet and freezing rain (be watchful of slick spots if traveling north Tuesday morning). Sunshine will make a quick return and “work” on our temperatures to help boost afternoon highs into the middle 40s (once again :-))! Another fast-moving weather maker will arrive late Tuesday night into Wednesday morning with mixed light rain and light snow. Again, light is the key word.
Colder, but drier weather will build in for the midweek stretch. The next weather item on the agenda will be a more vigorous clipper system that will slide southeast and result in increasing cloudiness Saturday night into Sunday morning followed by snow overspreading the region Sunday morning. Accumulating snow is possible Sunday afternoon into Monday morning and will require fine tuning in the days ahead. Precise track of the clipper system will determine where little, if any, snow falls and potentially several inches. Stay tuned. Regardless of the snow potential over the weekend, the stage is set for a MUCH colder time of things next week…

Longtime viewer and friend of IndyWx.com, Rick Ehrhardt, sent this fantastic Monday evening sunset from the Avon area. Thanks, Rick!

January is off to a colder than average start across a large portion of the country, including the Hoosier state:
The snow and ice pack has expanded over the past couple of weeks in rather significant fashion:
Two storm systems have offered up busy times over the Ohio Valley the past week. Note liquid equivalent numbers the past (7) days- most significant over central Indiana. Most of this has been in the form of wintry precipitation (snow and ice).
A weak weather system may offer up light snow chances mid week. The high resolution NAM and European print off light snow while other models “see” us mainly dry mid week.
The other big story in the short term will be more bitterly cold arctic air (single digits tonight and close to zero Wednesday morning).
While we’ll certainly “warm” compared to the freezer we’ve been in the first two weeks of January, sneaky arctic highs remain on the field and will put a dent in the air masses from reaching unseasonably mild levels for any length of time this weekend and Week 2. See Friday’s GFS output and the sneaky arctic high north:
The next significant storm system brews around the 20th (give or take a day, or two) and could offer up rain or a more wintry option. Keep a close eye on the period 01.20 – 01.23.
Thereafter, the arctic hounds likely come calling again as the period quickly returns to “lock and load” cold late January into February. The European and GFS ensembles both show a rebuilding blocking AK ridge and suggest arctic air floods the country yet again as cross-polar flow gets involved:
It’s all part of a package that should be the beginning of a colder than average and stormy mid and late winter stretch. Sea surface temperature anomalies are a textbook setup for a very wintry time of things for our neck of the woods. Note the Modoki El Nino and warm waters sitting off the PAC NW- both cold/ stormy indicators here:

Greatest ice accumulations set up from Indianapolis and points north last night and this morning. Glaze reached just under one quarter inch here across southern Boone County.
The icy mixture will transition to light snow before ending mid morning.
Temperatures will also be sliding backwards through the day. Morning highs in the lower 30s will fall into the 20s this afternoon.
The big push of arctic air arrives tonight into Tuesday and sets the stage for widespread sub-zero lows Wednesday morning. Wind chills will, of course, be even colder (10 to 20 below zero).
We’ll be back later tonight to talk about what lies ahead in the longer term. Stay safe out there!
