A few round of winter weather will impact the Wabash Valley this weekend. One much more potent than the other.
The first chance to see snow will move in through the overnight tonight into Saturday morning. This won’t be a major event with only an inch of snow at most expected.
Saturday will be dry and warmer with daytime highs back in the lower 40s.
A Winter Storm Watch goes into effect at 1 AM EST on Sunday. Snow & ICE accumulations are possible beginning around 1 AM Sunday through Monday morning.
The snow/sleet line looks to be just north of the I-70 corridor. Expect snow north and a snow/sleet mix elsewhere. This is Sunday morning.
Most of the Valley will continue to see a mix of mainly sleet and snow into the evening on Sunday. Here’s 7 PM:
We’ll start to see the sleet/snow line dip south after the 10 o’clock hour Sun. Snow becomes the main precip type. A bulk to the precip exits the area by early Monday morning. The Winter Storm Warning expires at 7 a.m. EST Monday.
Highest snowfall north of I-70 with 6-8″ and isolated spots up to 10″ possible. The snow/sleet line still isn’t a sure thing, but where sleet mixes in mainly along and south of I-70, snowfall accumulations will be a bit less but up to 0.25″ of ice is possible. Either way, travel will become dangerous and should be limited during the second half of the weekend.
Stay tuned to Storm Team 10 as we head through the weekend.
The Storm Prediction Center has expanded the ‘slight risk’ of severe storms area to include the entire Wabash Valley. Damaging winds gusts up 60+ mph and flash flooding are the main concerns. It isn’t out of the question storms embedded in the line could contain rotation leading to brief spin-ups, although straight line winds look to be a bigger issue. Main timing of this is between 4 and 8 p.m. EST.
A line of t-storms develop along the cold front impacting our IL counties first just after 6 p.m. EST/5 p.m. CST. The line will push into our IN counties around 7 p.m. EST. We could see a few isolated thunderstorms popping-up ahead of the main line. These storms have the potential to reach severe limits with damaging wind gusts.
The line of thunderstorms will begin to exit our IL and impact mainly our IN locations around 8 p.m. EST. This is a very typical “squall line” set-up with all the upper-level atmospheric support needed for strong storm development. By 9 p.m. EST, this quick moving line will move into central Indiana and start to exit the Wabash Valley. Severe threat diminishes at this point as well.
Strong winds (45+ mph gusts) continue during the overnight/early Friday morning. Cold air returns & a few snow flurries are possible.
Stay tuned to Storm Team 10 throughout the day as we continue to bring you the latest both on-air and online at wthitv.com.
Our next winter weather system set to move in during the morning hours on Monday in Illinois first and into our Indiana counties in the mid-morning/midday hours. A Winter Weather Advisory will be in effect for our Illinois counties from 6 a.m. – 6 p.m. CST Monday and in Indiana from noon through 7 p.m. EST.
This is another one of the tricky winter systems where the snow/sleet/freezing rain line will set-up through the heart of the Wabash Valley. Temps will be between the 31° – 35° range from north to south.
Here is Futurecast throughout the day on Monday:
10 a.m. EST:
3 p.m. EST:
8 p.m. EST:
NORTH OF I-70:. A snow/sleet mixture will set-up north of I-70 and change into more of a sleet/freezing rain mixture after midday. Freezing rain will transition back into snow between approximately 3 – 5 p.m. EST. This area has the highest snowfall potential, around 2″ -4″ plus 0.10″ ice.
I-70 Corridor: Warmer air will be in place along the I-70 corridor which means this area will experience more of a freezing rain/rain mix event for most of the day before transitioning back into snow at approximately 3 – 5 p.m. EST. Look for 1″ -2″ of snow + 0.10″ ice.
South of the I-70 Corridor: The “tricky” freezing line will bounce back and forth along and south of the I-70 line tomorrow creating the toughest part of the event to forecast. It looks like this area will experience a light freezing rain/sleet mixture until midday then changing to mostly rain, perhaps an occasional freezing rain mix in the afternoon. There is a chance we could see the precip changing into snow briefly on the back edge heading into the evening hours, but right now it looks like a bulk of the “snow” potential stays at bay along and north of I-70. Less than 1″ of snow is possible plus some light icing.
This system will exit the Valley after 8 p.m. EST to the east. Keep in mind the most “potent” precipitation times will be in the afternoon which will make for a slick and difficult evening commute home.
Warmer temperatures move in for the remainder of the week with highs back into the 40s by Tuesday.
We’ll keep you posted with the latest as we track this next weather system to impact the Wabash Valley.
A winter system we’ve been tracking over the past week arrives in the Wabash Valley today. A Winter Storm Warning begins for most of the Valley at 1/12c this afternoon and are the counties highlighted in pink. In purple is the area for a Winter Weather Advisory. This includes Effingham, Jasper, Crawford, Lawrence, Richland and Clay counties in Illinois. The advisory also goes in to effect at noon CST.
Lighter snow will be possible out ahead of the bulk of moisture this morning. Heavier snow will begin just after midday today and bring moderate to significant snowfall during the late afternoon through early Wednesday morning. Below are Futurecast images from noon, 5 PM and 7 PM.
Snow will mix with sleet at times south of I-70 which will cut snowfall potential down in those areas. Highest snowfall totals will be along and north of the interstate with 7-9″ possible. Along the I-70 corridor, we could still potentially see a brief sleet mix but it looks to be mostly snow with snowfall potential of 5-8″. To the south, 3-5″ of snow plus 1″ of sleet and potentially 0.1″ of ice.
Snowfall totals have increased slightly because of the positioning of the sleet/snow line. At this point, it looks like that transition line will lift as far north as I-70, although it appears Terre Haute will see mostly snow. With more areas expecting more snow and less of a sleet mix, snowfall potential has slightly increased.
Measurable snow tapers off during the morning hours on Wednesday but blowing snow will continue to be as concern as well as dangerous travel. Only emergency travel will be recommended.
We’ll continue to bring you the latest weather updates throughout the day on-air and online.
The latest model runs are in and as projected, there are some changes. It looks like the “center of low pressure” track will be further south which means more snow/less sleet and higher snowfall potential for the I-70 corridor and northward. Southern areas can still expect to see sleet and minor ice accumulations. Based off of this new information, the National Weather Service in Indianapolis has issued two separate Winter Storm Warnings for our Indiana counties, a Winter Storm Warning for our Illinois counties along and north of I-70 and a Winter Weather Advisory for the remainder of our IL counties.
The first Winter Storm Warning will go in to effect tomorrow at 1 PM EDT for Vigo-Clay-Owen-Putnam-Parke-Vermillion counties through 1 PM EDT Wednesday. These counties will experience a mostly to all snow event beginning Tuesday afternoon with the heaviest during the early evening Tuesday – early morning Wednesday. Expect 4-7″ of snow + up to 1″ of sleet/wintry mix along of the I-70 corridor with 7″+ north of the interstate.
The second Winter Storm Warning will go in to effect tomorrow at 1 PM EDT for Sullivan-Greene-Monroe-Knox-Daviess-Martin counties through 1 PM EDT Wednesday. While a sleet/freezing rain mixture is still possible in these counties, the changeover to all snow will happen sooner, upping snowfall potential. Look for 3-5″ of snow + 0.1″ to 0.2″ of ice by Wednesday morning.
A Winter Storm Warning will go in to effect tomorrow at noon CST Tuesday for Coles-Douglas-Cumberland-Edgar-Clark counties through noon CST Wednesday. It will be an all snow event for these counties where 7″+ will be possible. Wind gust of 25-30 mph will make for blowing snow and reduced visibility as well.
A Winter Weather Advisory will go in to effect tomorrow at noon CST for Effingham-Jasper-Crawford-Clay-Richland-Lawrence counties through noon CST Wednesday. Many of these areas can expect 3-5″ with perhaps a light icing as well.
In addition to the wintry precipitation, winds will start to pick up Tuesday afternoon causing blowing and drifting snow.
We’ll continue to bring you the latest information as it becomes available. Again, for now we recommend to plan ahead to limit travel as it will become hazardous or impossible in some areas.
Today & Tonight: We’re looking a day full of sunshine with below average temps. Daytime highs top out near 25 this afternoon. A few clouds filter in through the overnight, but it stays calm with lows near 16.
Tuesday: A winter storm will impact the Wabash Valley beginning Tuesday afternoon and lingering through the first part of the day Wednesday. A Winter Storm Watch will be in effect beginning at 1 PM EST Tuesday lasting through 1 PM EST Wednesday along and north of I-70. More areas south of the interstate could possibly added to this area and we’ll keep you posted with the latest in watches and warnings.
Timeline on Tuesday: Snow looks to move in to the area around midday Tuesday. First impacting our Illinois counties moving west to east. Snow will pick up in intensity with a wintry mix (mainly sleet) south of I-70 around the 7 o’clock hour on Tuesday. The wintry mix looks to transition back into snow after midnight. Totals will be cut down south due to ice/sleet, so the timing of this transition is crucial and still has the potential to change. Snow looks to exit during the morning hours on Wednesday. Skies remain mostly cloudy and blowing snow still could be a concern.
Precipitation Potential: This looks to be an all snow event north of I-70 which means this area has the highest snowfall potential of 6″+ possible. Along the I-70 corridor will be where the “sleet/snow” line sets up, but it’s exact location isn’t set in stone. Therefore, if we see the line sinking a little further south, we will see more snow and amounts closer to the 6″ mark along the corridor. If the line lifts further north, we’ll see more a sleet/snow mixture taking totals down, closer to the 3″ mark. Nonetheless, expect a range of 3″ up to 6″ along the interstate. Further to the south, a wintry mix of sleet and freezing rain looks to take snowfall potential down significantly with 2″-4″ possible plus 0.1″ to 0.2″ of ice. There is still a level of uncertainty, especially where the snow transitions into sleet and that depends on the storm track.
Extended Outlook: Our early-week winter storm will be followed up by a cold blast of air Thursday and Friday. Another wave of snow returns next weekend.
A stalled frontal boundary will reside in the area through late Saturday bringing a mixed bag of wintry precipitation over the next couple of days.
Today: Look for a cloudy sky with periodic afternoon light snow showers. Daytime highs near 35.
Tonight: A surge of warm air will lift northward through the overnight changing snow into a snow/freezing rain mixture after midnight. Temperatures warm enough by daybreak Saturday to change all our precip into rain showers all throughout the Wabash Valley. Nonetheless, a brief icing through the overnight could leave roadways rather slick some Saturday morning. The following are images from Futurecast at 1 a.m. and 7 a.m. Saturday.
Saturday: Scattered rain showers will be likely through the day on Saturday with highs in the mid 40s. Rain will possibly mix with light snow as this system departs the region before midnight Saturday.
Sunday: Partly cloudy and much colder with highs near 24. We’ll start the day near 21.
Extended Forecast:The highly talked about weather system for next week looks to move in during the day on Tuesday. Models are still not agreeing on the type of system we’ll see next Tuesday. The “track” of the low pressure will play a huge roll and each model positions it a little differently. Depending on it’s track, we could see all snow or a wintry mix/ice event which will drastically take down snowfall totals but add a completely separate set of problems. Once the models start agreeing more on on the storm’s track, we’ll have a better idea of not only what type of precipitation we will see, but how much. Stay tuned!
Arctic air is settling into the Wabash Valley bringing well below average temps in over the next several days.
Today:Skies will be mostly cloudy today with there is a chance for a light snow shower or two (perhaps a dusting or light coating at most). Temps rebound to near 22. Winds will be gusty out of the southwest.
Tonight: A Wind Chill Advisory will go into effect for all of our IL counties beginning at 9 p.m. CDT lasting through noon Thursday. We’ll drop back to 0° with increasing winds gusting to 30 mph out of the northwest. This will drop wind chill values to as low as -20° at times. Skies will be partly cloudy.
Tomorrow:Thursday will be the coldest day we see this week with highs only near 8° under partly cloudy skies and gusty northwesterly winds.
Extended Outlook: Temperatures stay cold through Friday with highs back in the upper 20s this weekend. We’re looking at two waves of snow moving in this weekend as well. The first wave will move in Friday night lasting through Saturday morning with 1-3″ possible. Another wave Sunday afternoon through Monday morning will bring an additional 2-4″ of snow.
Today: Scattered snow showers are possible today as an upper level wave tracks through the Wabash Valley. This wave will also bring in colder temps. Temperatures will stay steady in the lower teens throughout the day with sub-zero wind chill temps.
Tonight: It turns cold tonight with lows back near 9 under mostly cloudy skies. A few flurries will be possible with the cloud cover in place.
Tomorrow: More accumulating snow is in the picture for Saturday afternoon and evening. Snow will move in just after midday and become heavy at times through the late afternoon and early evening.
The snow showers look to come to an end just after midnight, early Sunday morning. Highest snowfall total look to be across northeastern portions of the Valley with up to 4″ possible. Most of the Valley will see 2-3″ with lesser amounts, 1-2″ across southwestern portions of the Valley.
Sunday:The sun comes out, the winds shift out of the southwest and temps return to the upper 30s on Sunday.
Extended Outlook: We’re looking at a cold snap for mid-week next week. While we look to stay dry, Tuesday and Wednesday will only see highs in the teens with overnight low temps in the single digits.
