  • Wet To White (At Times) Through Early Week…

    A quick note before we dive into the upcoming forecast pattern.  Instead of issuing 7-day posts within the blog format, the most updated IndyWx.com 7-day forecast will now be featured at the top left of the site.  We’re continuously trying to provide you the information and content you need in a quick and concise manner- eliminating having to “scroll and search” (unless you’re bored, of course ;-))!

    Areas of fog and drizzle will continue this evening before a stronger southwesterly air flow pushes the low clouds and fog north during the overnight.  As a cold front draws closer, steadier rains and perhaps even a clap of thunder (especially down state) will arrive Monday morning.  Temperatures will remain nearly steady or even rise overnight into the lower 50s.

    The frontal passage, itself, will take place Monday evening and may feature a couple of gusty showers, especially across western and central portions of the state.

    Temperatures will grow colder Monday night into Tuesday morning and precipitation will end as snow showers Tuesday.

    High pressure will build in through midweek and provide dry conditions with increasing sunshine.  The midweek stretch will begin seasonable before warming ahead of our next storm system.

    That next storm system will deliver rain as early as Friday evening into Saturday.  We’ll note an increasingly gusty southwesterly breeze as we wrap up the work week, along with increasing cloudiness.


  • Milder, But Active…

    Highlights:

    • Gloomy close to the weekend
    • Rain-to-snow early week
    • Significant storm next weekend

    Drizzle And Fog Develops…Our Saturday opened with plentiful sunshine and milder conditions.  Unfortunately, the low cloud deck invaded through the afternoon hours and will take up residence through Sunday.  Fog and drizzle will develop tonight and continue through most of Sunday.

    Steadier rains will arrive on the scene late Sunday night into Monday morning ahead of an approaching cold front.  That cold front will sweep through the state Monday afternoon with additional showers and a dramatic wind shift.  Colder air will then press into the region and as wrap around moisture swings through the state, snow showers will develop Tuesday.

    As mentioned in previous posts, we’re in a transient and very active regime.  Just as soon as the colder air arrives for midweek, we’ll shift our air flow around to the southwest and usher in milder times to close the week.  A significant storm system is brewing next weekend.  We’ll forecast increasing cloudiness Saturday with rain arriving by afternoon.  We’ll have to keep tabs on next Sunday for the possibility of wintry conditions returning…

    Upcoming 7-Day Precipitation Forecast:

    • Snowfall: Dusting
    • Rainfall: 0.50″ to 1.00″


  • “Less Harsh;” Weekend Rain…

    Highlights:

    • Turning “less cold”
    • Weekend rain
    • Chilly early next week

    Sunny And Not As Cold…The arctic high that delivered the bitterly cold conditions over the past few days is scooting off to the southeast.  This will put the state under a milder (all relative :-)) southwesterly flow and temperatures will become “less harsh” as we wrap up the work week!

    An approaching storm system will lead to increasing clouds during the afternoon and evening Saturday and drizzle will follow Sunday morning.  As the cold front draws closer, steadier rains will arrive Sunday night into Monday.  Colder times will sweep in behind the front and allow left over precipitation to end as snow showers Monday (not a big deal).

    Tuesday and Wednesday will feature dry and chilly conditions.

    Upcoming 7-Day Precipitation Forecast:

    • Snowfall:  Dusting
    • Rainfall:  0.25″ to 0.75″


  • Monday Morning Notes…

    Bursts of moderate to heavy snow will work across the metro during the next couple hours. This will lead to significant drops in visibility and serve to mess up roadways even more than they currently are. If you don’t have to travel through the morning hours we recommend staying home and allowing road crews time to get things cleaned up.

    Most of the steady accumulating snow will be over with by late morning and we’ll just be left with scattered snow showers through the afternoon hours. Perhaps the bigger story by then will be significant blowing and drifting snow as gusty westerly winds help usher in colder air. If your travels include country roads, or north-south oriented highways, plan on considerable blowing and drifting snow this afternoon and evening.

    We have no changes to our going snowfall forecast with this system.

    Finally, as the arctic front sweeps through the state this afternoon, it’ll likely kick up some intense, blinding snow bursts.  While these won’t last long, they’ll blast through during the evening rush and will serve to dramatically lower visibility.  We note high resolution models are picking up on these snow bursts on forecast radar products.

    We’re left tonight with bitterly cold conditions that will continue to grip the region through midweek. Most of us Tuesday morning will be below zero. A moderating trend will develop by late week, continuing through the weekend!


  • Gas Up The Plows; Arctic Air Returns…

    Highlights:

    • Heavy snow Monday morning
    • Bitter air returns
    • Milder, wet weekend

    Snowy Open To The Week…A vigorous clipper system and associated arctic cold front will drop southeast and spread a swath of snow across the region tonight into Monday.  We expect light snow to encompass most of central Indiana later this evening (between 7p and 10p west to east) before increasing in overall intensity during the overnight.  Periods of moderate to heavy snow can be expected during the mid-morning hours Monday, including impressive snowfall rates at times.  Allow plenty of extra time to reach your destination Monday.  Steady snow will give way to scattered snow showers during the afternoon, continuing into Tuesday as fresh arctic air pours into the region.  By the time all is said and done, most of the region can expect a fresh 2″ to 4″, including some locally heavier totals.  The other item on the agenda will be blowing and drifting snow that we’ll have to deal with Monday afternoon through the night and into Tuesday.

    Arctic high pressure will settle overhead Tuesday night through the midweek stretch, allowing sunshine to return, but we’ll remain well below average (average temperatures this time of year include highs in the mid-30s and lows around 20).

    A moderating trend takes place late week, but the “less cold” air will come with gusty southwesterly winds and increasing clouds Friday.  Those clouds will give way to periods of rain along with milder conditions over the weekend as an area of low pressure tracks into the Great Lakes.

    Upcoming 7-Day Precipitation Forecast:

    • Snowfall: 2″ to 4″ (locally heavier totals)
    • Rainfall: 0.25″ to 0.75″


  • Another “Plowable” Snow Gives Way To Sub-Zero Cold…

    With the exception of light lake effect snow showers today (noticing a couple of light bands just west of the city as we write this Saturday morning around 10a), most of today and Sunday will be dry and cold.  We’ll top out around 20° today and Sunday with low temperatures tonight dropping into the 0° to 5° range.

    Our next snow maker will arrive late Sunday night into Monday morning in the form of a clipper system.

    Forecast radar 1a Monday.

    We expect light snow Monday morning to grow in overall coverage and intensity through the late morning and into the early afternoon hours.

    Forecast radar 10a Monday.

    Accumulating snow will push off to the south Monday evening.

    Forecast radar 7p Monday.

    This will be a plowable event for central Indiana and we’ll also have to deal with blowing and drifting concerns Monday afternoon through Monday night as strong and gusty northwest winds arrive.  Needless to say, to our snow removal and DPW crews out there, find a way to get some rest this afternoon and Sunday before another busy stretch to open the work week.  We think additional snowfall of 2″ to 4″ is a good bet across the northern half of the state, with slightly lighter amounts of 1″ to 2″ across southern Indiana.

    Arctic high pressure will settle over a growing snowpack to help setup a frigid stretch through early and mid week.  Multiple nights with below zero readings are expected beginning Tuesday morning where most will wake up to readings of 3° to 8° below zero (not counting the wind chill).


  • Wintry Forecast; New “Plowable” Snow Event Arrives Monday…

    Highlights:

    • Sleet changes to snow
    • New snow and wind maker Monday
    • Bitter air returns

    Double Shot Of Impactful Winter Weather…A mixture of sleet and freezing rain will begin to transition to snow from west to east as we progress through the late morning into the early afternoon.  We don’t have any significant changes to our snowfall forecast (remember this doesn’t include the freezing rain and sleet accumulations that have led to travel issues this morning already).  Embedded snow bands will likely result in enhanced snowfall rates into the early afternoon across central Indiana.

    Precipitation will end for all except southeastern portions of the state by mid-to-late afternoon and then we’re left with the “clean up” from round one.  Saturday and most of Sunday will feature dry and very cold conditions.

    Our attention this weekend will then shift to a potent clipper system that has eyes on central Indiana late Sunday night into Monday.  Snow will overspread the region during this timeframe and given the nature of this event, heavier, more intense snow bursts are also expected to accompany the fresh arctic air that will drill in here Monday evening.  This will be an impactful event not only from the new falling snow, but from problems that wind and drifting will bring, along with a new batch of sub-zero temperatures.  Our snowfall forecast Monday hasn’t changed since yesterday, including widespread additional amounts of 2″ to 4″.

    Dry, but bitterly cold conditions return for the mid and late week stretch.

    Upcoming 7-Day Precipitation Forecast:

    • Snowfall: 3″ to 6″
    • Rainfall: 0.00″

    *Please note the 7-day precipitation forecast outlined above is for Indianapolis proper.


  • Ice Transitions To A Double Shot Of Snow; Frigid Times Return…

    Highlights:

    • Bye-bye thaw
    • Ice to snow Friday
    • Second snow maker Sunday night

    Active Forecast Period…A breezy southerly flow will dominate our weather today ahead of an approaching cold front.  Showers and unseasonably mild conditions can be expected today.  (Despite the snow lover in me, I will admit that it’s been mighty nice being able to jog outside without worrying about slipping on ice or snow the past couple days).

    Things begin to change in rather dramatic fashion tonight as the cold front presses through the state and allows much colder air to “ooze” back into central Indiana.  At the same time, a wave of energy will track northeast along the cold front and help spread more widespread moisture into the colder air at the surface.  We expect rain to begin mixing with and changing to an icy mixture of sleet and freezing rain after midnight across western and central portions of the state, and closer to 5a-6a across eastern Indiana.  Eventually, as the entire column of air cools, icy precipitation will transition to snow.  If the sleet to snow transition occurs faster, snowfall totals will be at the higher end of the first call numbers outlined below.  Should sleet hold on for a longer period of time, snowfall amounts will be on the lower end of forecast totals.  We think snow will end around noon west of the city, but steady snow will hang on much longer across eastern sections of the viewing area- well into the evening hours.

    Here’s our first call snowfall forecast for Friday.  While this doesn’t include freezing rain amounts, we think a glaze up to 0.10″ is a good bet – especially on elevated and exposed surfaces.

    Dry conditions will return Saturday along with a much colder feel.  Quiet times won’t last long as another snow system will quickly begin to impact the state Sunday evening into Monday.  Widespread steady snow is expected to develop and will actually be a more uniform, bigger, event for most of the viewing area.  We’ll add in wind and arctic air which will lead to blowing and drifting issues as the day progresses Monday into Tuesday.  Here’s our first call for additional snow amounts Sunday evening-Monday.

    The forecast period will wrap up dry and bitterly cold.  With a fresh snowpack down, it’s safe to say we’ll add at least another night to the sub-zero “club!”

    Stay tuned, friends!
