Slick Start Tuesday To Snow Potential Wednesday

Posted By · March 2, 2015 at 4:32 pm

Buckle up for a wild weather ride the next 48 to 72 hours Central Indiana.  All is quiet this evening with an increase in clouds expected as our next weather system approaches from the west.  All of the viewing area is under a Winter Weather Advisory that begins at 3am and runs until midday Tuesday.


An area of sleet and freezing rain expands eastward late tonight into the Tuesday morning commute.  It may not be heavy precipitation, but it will be effective falling onto sub-freezing surfaces like sidewalks and roadways.  This will lead to slick travel for several hours in the morning with temperatures not anticipated to climb above freezing until around midday.



Rising temperatures and locally heavy rainfall increases the risk for flooding Tuesday evening… though it’s uncertain at this point where the heaviest rain-banding will set up tomorrow.  It should be noted that underneath the heavier bands of rain rainfall amounts of .25″ to .75″ are possible.  Rainfall on the heavy snow pack and frozen ground could lead to excessive runoff.


We’re closely monitoring snow potential Wednesday as colder air returns and teams up with abundant moisture from the Gulf of Mexico.  At this juncture it’s a bit uncertain where the heaviest snow axis develops.  But it appears somewhere between I-70 and the Ohio River could be the bulls eye… as various model outputs show heavy (6″+) snowfall in this region.  We’ll refine this forecast tomorrow and don’t be surprised if the Winter Storm Watches in southern Indiana/northern Kentucky expand farther north to include more of Central Indiana.


Near record cold temperatures arrive after Wednesday, with lows nearing zero to sub-zero Thursday and Friday mornings.  Though bitterly cold… both days feature decent sunshine and quiet conditions compared to the beginning of the week.  We’re going to keep the weekend dry for now but may need to add light precipitation chances.  Stay tuned for updates on a highly changeable forecast for Wednesday – Sean Ash

Latest Timing and Totals for Sunday’s Snow

Posted By · February 27, 2015 at 10:51 pm

Here is the latest timing for the snow and wintry mix on Sunday.  The timing is similar from earlier analysis, but the rain/snow line is a little farther south.  Remember where this stays all snow, snowfall potential is 4″+.  We still the best chance for these higher totals will be north of Indianapolis.  The rest of central Indiana will be in the range of 2-4 inches of snow.

Light Snow Update and Another Arctic Blast

Posted By · February 25, 2015 at 10:04 pm

Light snow will continue to move into central Indiana Wednesday night and snow showers stay in the forecast for Thursday.  We are not forecasting a lot of snow, but most of central Indiana will have a dusting of new snow with a few places north and northwest of Indianapolis closer to 2 inches.  Here is the timing with FutureTrak13.  The timing is a bit tricky, as there will be a few snow showers for the Thursday morning commute.  There will also be bursts of snow Thursday afternoon and evening, as the arctic air arrives.


Highs on Thursday will be in the upper teens and lower 20s.


We will really feel that arctic chill Friday morning through Saturday morning.  Low temperatures are forecast below zero both mornings and at record breaking levels on Saturday morning.  Highs on Friday will only be in the teens.

We are tracking a developing weather system for the end of the weekend.  Right now, snow is forecast to start falling early Sunday morning.  Snow and a wintry mix are possible throughout the day on Sunday, with accumulations possible.  It is a bit too early for totals, but we will keep you updated.  You can see the system developing on Saturday to our SW with FutureTrak13.

The forecast for early next week isn’t easy either.  There will be snow, rain and ice chances Monday through Wednesday.  Our weather pattern stays active over the next 7 days.

Milder Now, Snow Later

Posted By · February 25, 2015 at 5:39 am

Not quite as cold this morning, but we will see this cold weather stick with us into next week. Our high today reaches the mid 20s.

Look for another chance for snow tonight and Thursday. This system will bring the chance for an inch or 2 of snow to central Indiana. Some of the latest computer models show that there could be some slick spots for the morning rush hour tomorrow.

Look for highs to roll back into the teens by Thursday and Friday. You can expect near record low temperatures on Friday morning. We have -3 in the forecast and the record is -7 in 1963. The record low for Saturday is 2 in 1993 and we are forecasting that one to fall, with forecast lows near -6 degrees.

Highs will reach the mid 30s by Sunday but… you can also expect a bit of snow/wintry mix in the forecast . Looks like March will come in like a cold lamb!

Winter Storm Update

Posted By · February 20, 2015 at 10:30 pm

The SkyTrak13 Weather Team continues to track a developing winter storm.  A winter storm warning is in effect for most of central Indiana until 7pm Saturday.  It is a winter weather advisory for Logansport, Peru, Marion and Hartford City.  We are forecasting a widespread 3-6 inch snowfall for central Indiana.  We do think most of central Indiana will be on the high end of that range.  The totals will be closer to 3-4 for Lafayette to Kokomo and Marion.  We have 1-3 inch snowfall potential for Bedford, Seymour and North Vernon due to the potential for freezing rain.  This is where this winter storm gets tricky.  There should be a layer of warmer air above the surface changing the snow to freezing rain across the southern part of the state.  We will watch this closely and adjust snowfall potential if needed.

WARNING totals

The winter storm is arriving on schedule.  The leading edge was in SW Indiana at 10pm.  We are still forecasting the heaviest snow from about midnight through 7am.  Travel will be difficult through at least Saturday afternoon.  Allow extra time and remember your winter safety kit if you have travel plans for Saturday.  Here is the latest timing with FutureTrak13.

From snow to 2 rounds of arctic air, it is cold and snowy 7 day forecast.

Update On Super Bowl System And Refreeze Tonight

Posted By · February 1, 2015 at 3:25 pm

We always say “track means everything” for a reason.  In this particular case it’s a warmer, more northerly track that’s pushed snow accumulations northward accordingly.  Here’a  preliminary list of totals since 3pm… but note that I expect significant melting the next few hours to diminish what’s on the ground and what you ultimately shovel which will be on low end of forecast:

Peru – 4″

Purdue University – 3″

Fishers – 3″

Lebanon – 2″

Traders Point – 2″

Carmel – 1.5″

Castleton – 1″


The center of the storm will pass either over Indianapolis or possibly to the north.  This will put a good share of the viewing area into the “warm sector” and temperatures likely reach the upper 30s/lower 40s along and south of the I-70 corridor.  Roads will be wet to slushy in spots but passable for many south of I-74.


Rain will be likely for several hours early this evening and possibly come down heavy in some locations in Central Indiana… with snow likely the more dominant precipitation type from Lafayette-Kokomo-Marion.  This area has the greatest chance of getting the higher totals of 6″ or more.  But I’m more concerned at the refreeze that takes place overnight into the Monday morning commute.


Temperatures drop below freezing around or just after midnight.  By sunrise… low temperatures area wide drop into the teens and lower 20s.  This will make for rather slick roads due to snow and rain refreezing.  We anticipate delays and cancellations and added time to your drive Monday.  There will also be a period of snow and snow showers overnight before the system quickly departs.  Additional accumulation is very possible and it would be a more fluffier snow within colder air.  I’m definitely not ruling out another 1-2″ for some overnight.


Strong cold air advection keeps temperatures in check tomorrow.  Expect daytime highs in the teens for most and wind chills in the zero to 10 above range.  Clipper system snow is possible Tuesday night into Wednesday, with another chance of snow Thursday along an approaching Arctic front.  The busy pattern continues next weekend with rain/snow chances Sunday.


Thanks for reading the blog and remember video forecasts are also available at wthr.com/weather & our free Skytrak13 weather app http://www.wthr.com/category/225686/wthr-skytrak-weather-app.  Have a safe evening – Sean Ash

Cold Tonight and Rain, Snow and Wintry Mix in the Forecast

Posted By · January 27, 2015 at 4:30 pm

It will be dry, but cold across central Indiana Tuesday night.  We are forecasting low temperatures in the middle and upper teens.


Believe it or not, it is still snowing along the East Coast.  Snow totals are in feet and there will still be some travel trouble over the next couple of days, as they dig out of the blizzard.

rpm4 RPM5

Locally, we are more than 14 inches below average for snow this season.  In Indianapolis, there has only been 2.5″ of snow since December 1st.  There are snow chances in the forecast.

It will be dry on Wednesday, with high temperatures in the lower and middle 30s.  We are tracking a developing weather system that will arrive late Wednesday and linger into Thursday.  We are a bit concerned as the rain starts to fall, it might be cold enough at the surface for some freezing rain late Wednesday night.  Temperatures are forecast to climb into the upper 30s and lower 40s on Thursday.  It will be an up and down day because colder air will wrap into the weather system, as it moves out of central Indiana Thursday night.  The rain may again mix with a wintry mix or snow.  We are not forecasting any accumulations.

That may change with a winter storm system on Sunday.  Stay tuned for updates.

Winter Weather Advisory Saturday AM

Posted By · January 2, 2015 at 4:22 pm
Winter Weather Advisory for parts of central Indiana from 3am to 9am Saturday

Lafayette, Kokomo, Anderson, Muncie are included.

The SkyTrak13 Weather Team is tracking a developing storm system for the weekend.  Temperature will be key to the type of precipitation late Friday night and early Saturday morninig.  We are forecasting temperatures to fall into the range of 27 to 33 degrees.  These temperatures are cold enough to support freezing rain for a few hours early Saturday.  Watch for icy and slick roads overnight through about 9am Saturday.

As temperatures warm above freezing, this will become a heavy rain event for Saturday.  Rainfall potential is around an inch.  Highs on Saturday will be in the range of 45-50 degrees.  It will stay that mild Saturday night, but colder air arrives on Sunday.  Temperatures will fall into the 20s.  As the colder air arrives a few flurries and snow showers will be possible.  Sunday will be a windy day too, with winds WNW 20-30mph.

The chill will linger through much of next week and we are tracking another chance for snow on Tuesday.
