- Another arctic shot
- Milder for the weekend
Snow Showers Develop Overnight…Another fast moving upper air disturbance is on the move southeast this morning and will result in a mostly cloudy and blustery open to the work week. As cold air advection (CAA) kicks in overnight and Tuesday, snow showers will develop across the region. We’ll also note the potential of a more intense and persistent lake effect band setting up across east-central Indiana (where a couple inches will accumulate Tuesday). If your travels take you into eastern and northeastern portions of the state Tuesday, prepare for sudden drops in visibility and slick travel.
Additional upper level energy will scoot through here during the middle part of the work week and while this will help to reinforce the cold, it’ll also provide scattered snow showers.
We’ll switch gears and get into a briefly milder southwesterly air flow over the upcoming weekend. Strong and gusty southwest winds will aid in giving a boost to the mercury, but showers will make for a damp end to the weekend.
Upcoming 7-Day Precipitation Forecast:
- Snowfall: Dusting (for most) to 2″ across east-central Indiana
- Rainfall: 0.25″

Highlights:
- Lake effect squalls this afternoon
- Another arctic shot early next week
- Light snow chances
Hope You Like It Cold…Upper level energy is moving through the region this morning and is responsible for the scattered snow showers. Dry air “ate away” at the initial moisture and as a result we’re generally only looking at a dusting for most of central Indiana. The exception to that will be a narrow, but potentially intense lake effect snow band and embedded squalls that set up shop this afternoon. Under this band, an inch or two of snow will quickly accumulate.
Reinforcing cold, arctic air will pour into the state Monday night and Tuesday and will be accompanied by scattered snow showers. Another fast-moving disturbance will provide a shot of snow showers Wednesday night into Thursday.
All-in-all, no significant snow is on the horizon, but that may begin to change as Christmas nears. After brief moderation in the pattern next weekend, we’ll reload the cold pattern and likely see a stormy regime unfold, as well. Modeling suggests the southern stream will become more active in the weeks ahead…
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 1″
- Rainfall: 0.00″

Highlights:
- Cold times
- First accumulating snow of the season
- Additional disturbances to monitor next week
Snow Arrives Late Friday Night And Early Saturday…75% of our Thursday featured overcast skies and periodic flurries and light snow. Thankfully, a bit of drier air is working in to provide a brighter close to the day. A cold night is on deck as many fall into the teens.
A fast moving upper air disturbance will drop southeast into the Ohio Valley Saturday. This will help spread a swath of snow across central Indiana overnight Friday into the wee morning hours Saturday. Additionally, we’ll have to monitor the potential of enhanced lake effect bands across central and east-central portions of the state Saturday morning into the early afternoon. In general, we expect 1″ to 2″ of snow to accumulate across central Indiana, but note there may be a couple of heavier totals where lake effect bands set up.
Another fast-paced disturbance will blow into town Monday night into Tuesday, followed by another Wednesday night into Thursday. Cold weather will dominate through the period.
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 2″ – 3″
- Rainfall: 0.00″

Highlights:
- Cold air settles in
- 1st accumulating snow of the season
- Active northwest flow pattern remains
Unseasonably Cold…Northwest winds helped usher in a much colder air mass Tuesday behind an early morning frontal passage. While a couple of flurries are possible Wednesday, we’re mostly dry through the midweek stretch. We’ll notice resurgent cold and wind Wednesday night into Thursday. Heavy winter gear will be warranted.
Eyes will then turn to an approaching clipper system in what’s just the beginning of a busy northwest flow regime. We expect clouds to increase Friday evening and snow to develop overnight, continuing into the day Saturday. Given the dynamics in play, we still circle this period for the first accumulating snow event of the season. Sure enough, latest model data is also trending snowier during this timeframe. Another snow event looms late Monday into Tuesday with fresh arctic air drilling south early next week…
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 1″ – 3″
- Rainfall: 0.00″

Highlights:
- Falling temperatures Tuesday
- Much colder
- Active northwest flow
Winter Engaged…Showers and embedded thunderstorms will rumble across the state during the overnight as a cold front draws closer. This is a “game changer” of a cold front, separating anomalous warmth over the past few days to a locked and loaded winter pattern. Temperatures will fall through the day Tuesday and just enough wrap around moisture will be present to support mention of evening flurries.
Morning scattered snow showers will continue early Wednesday before a reinforcing blast of arctic air blows into town at night. This will set up a frigid close to the work week and feature a fast paced northwest flow pattern into the upcoming weekend. We’ll have to remain very focused on upper level energy over the weekend. Models have been struggling (as expected given the pattern) on the specifics and we know this type regime can overachieve in the snow department. As things stand now, a period of snow showers with light accumulation still seems like a good bet Friday into Saturday.
Another (potentially more significant) snow event looms early next week…
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 1″
- Rainfall: 0.25″ – 0.75″

Highlights:
- Showers and t-storms Monday night
- Turning much colder
- Snowy close to the work week
Changes Loom…We couldn’t have asked for a more delightful weekend to open December. Plentiful sunshine helped warm afternoon highs into the 55-60 degree range both Saturday and Sunday across central Indiana. We sure hope you found a way to get out and enjoy it as major changes loom.
A cold front responsible for ushering in these changes will blow through the state Tuesday morning. Ahead of the cold front, look for a line of showers and thunderstorms Monday night. For the most part, rain should be southeast of our region before the morning rush Tuesday. Winds will shift to the northwest and help usher in a much colder air mass through the day. This will set the tone for what the rest of the week will hold (and for that matter, most of the rest of the month).
Cold, dry conditions will be with us for midweek before a vigorous upper level disturbance races southeast across the Ohio Valley to close the work week. Snow showers and unseasonably cold conditions are a given Thursday night through Saturday morning and we’ll have to continue to monitor things closely for the prospects of the season’s first accumulating snow Friday. These type events have been known to “overachieve.”
The cold pattern is just setting in and shows no signs of departing in the longer range. Additional wintry “mischief” looms next week…
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 1″ – 2″
- Rainfall: 0.50″ – 0.75″

November 30, 2017
Highlights:
- Mild open to December
- Early week rain and storms
- Hello winter
Great Weekend By December Standards…High pressure will build in overnight and provide beautiful weather to open December. We’ll enjoy plentiful sunshine and well above average temperatures through the weekend and on into early next week. Take our word for it: Enjoy it while you have it!
An approaching storm system will lead to increasing clouds later Monday along with an increasingly gusty southwest breeze Monday afternoon into the evening. A cold front will move through the state Tuesday with widespread rain and embedded thunderstorms. Strong and gusty winds will continue. Once the front sweeps through the state, falling temperatures can be expected Tuesday evening.
The true shift to winter will begin the middle of next week, complete with MUCH colder air, gusty northwest winds, and scattered snow showers. Speaking of winter, if you’re a fan of the cold and snow for the holiday season, the upcoming pattern change will put a smile on your face. A prolonged stretch of cold and wintry conditions should continue through the holidays and into the new year…
Upcoming 7-Day Precipitation Forecast:
- Snowfall: Trace – Dusting
- Rainfall: 1″ – 2″

Highlights:
- Weak front passes through Thursday
- Sun-filled, mild weekend
- Big changes await
Enjoying The Relatively Quiet Weather While We Can…Dry conditions will remain in place today before a weak frontal boundary passes through the state Thursday. Enough moisture will return in advance of this front to help spark a couple of light showers, but this won’t be a big deal and several neighborhoods won’t pick up any rainfall.
We’ll get back to dry, quiet weather over the weekend as high pressure builds in. Sunshine and mild weather will continue. Given what looms, it’ll be a perfect weekend to complete any lingering outdoor work or get those Christmas lights up!
Big changes await next week as winter gets ready to settle in. The leading edge of the cold air will be accompanied by showers as we open the work week. Easily the coldest air of the season awaits for later next week…
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 0.00″

Highlights:
- Dry and quiet weather remains
- Shower chance Thursday
- Sunny weekend ahead
Boring Pattern Remains…An eerily quiet weather pattern will remain intact as we progress through the upcoming week. We’ll notice an increasingly gusty southwesterly breeze later today into Tuesday and this will help boost afternoon highs very near the 60° mark.
A weak cold front will pass through Thursday and while a shower will be possible as the front moves through the region, this won’t be a significant weather event. Slightly cooler air (not cold by any means) will arrive behind the cold front this weekend. The bigger news will be the continuation of extended quiet and sunny weather.
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 0.00″
- Rainfall: 0.10″
