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.
Another winter storm is headed our way. Here are the snowfall estimates as of Monday evening. These totals could change if the path of the storm changes. This storm is not extected to be as bad as the one we had at the beginning of January, but it will still cause travel concerns. Storm Team 10 will continue to track this storm as it gets closer to our area.
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 WINTER WEATHER ADVISORY is in effect until midday Saturday for the Indiana counties of: Parke, Putnam and Vermillion. In Illinois, Edgar, Coles and Vermilion. Snow, sleet and freezing rain will combine to make travel difficult. By Saturday midday, the precipitation should change to all rain, with a high of 45.
The temperature will get gradually warmer as we head into the second half of the week. A gusty southerly wind will bring in moisture, which could enhance our chance of snow late Thursday and Friday. Saturday, we could experience a wintry mix as the temperature edges into the upper 30s. Another system to watch will move in about Tuesday of next week. it’s too early to tell exactly what this system could bring, but Storm Team 10 will keep a close eye on this one.
During the day on Friday, clouds will increase and the wind will continue to be gusty. Overnight Friday, expect snow to develop. Gusty wind will make overnight travel dangerous. A few inches of snow will be possible by about noon on Saturday. At this point, we’re looking at around 1-3 inches along and north of I-70, but this number is subject to change as the syatem gets closer. Storm Team 10 will continue to track the next winter system.
