LATEST WINTER STORM OUTLOOK

Happy Friday everyone!  Before I get to the bad news, there is a little good news in the weather for now.  We have a brief warm-up on the way over the next couple of days.  Don't get used to it, because huge changes arrive beginning later tomorrow night as a potentially major winter storm moves in.

I updated the forecast for the short-term on my Facebook weather page.  For this blog I will only focus on the winter storm headed our way.  The NWS has gone ahead and issued a WINTER STORM WATCH for a good portion of the state.  This runs from late tomorrow night, and goes all the way through Monday morning.

 
This is going to be a long duration event.  It won't all come at once, it will come in waves through Monday morning.  We will begin to see some precipitation move in after midnight tomorrow night.  This will come in waves through 3:00 Sunday afternoon, then really pick up in intensity after that.  Temperatures for Sunday are tricky.  There is a chance the parts of southeast Indiana (Orange, Washington counties and points southeast) could stay warm enough Saturday night through early Sunday afternoon to only see plain rain.  However, even these spots quickly go below freezing Sunday afternoon and that is when the problems begin to occur.   

As we head into Sunday night, heavy icing is a big concern for extreme southern Indiana, before everything changes to snow by early Monday.  Here is my map for now.  I want to mention that the models have shifted the freezing rain farther southward, so the worst icing may even go south of Bedford/Seymour if trends continue.  I still think areas south of Bloomington and Columbus will have a lot of sleet which will cut down on snow totals, but sleet is SO MUCH BETTER that freezing rain.  There is question how much icing will occur in southern Indiana.  The big factor here is how long it will stay freezing rain before changing to sleet.  That will make a huge difference.  Areas closer to the Ohio river could see 1/4"-1/2" if not as much as as 3/4" of icing, again it all depends on the duration!  This could be enough to cause major problems to power lines, tree limbs, etc. so continue to keep a very close eye out on the latest forecast.  I will be closely monitoring the models today, and by this evening, I should have a much more detailed map.  **The exact track of this system could still change, and that will have big effects on the forecast.**

WINTER STORM LIKELY ON SUNDAY

Good morning!  Another arctic front is pushing through the state this morning, bringing even colder air!  The wintry pattern just keeps on keeping on, and a significant winter storm is likely for the second half of the weekend.  

Today will be brutal.  We have already hit our high temperatures early this morning.  Temperatures the rest of the day will stay steady if not drop a few degrees, even with full sunshine.  That is tough to manage considering the higher sun angle in late February.  

We do have a decent rebound in temperatures over the next couple of days, well at least considering how cold today is.  Our average high for this time of year is in the middle to upper 40's!!  Even with the "warmer" numbers over the next couple of days, we will remain below average.  

There is a weak system coming in tomorrow night, that should bring light snow across the state.  Some spots could see 1", other spots may totally miss out.  

The big weather story is the major winter storm expected for the second half of the weekend into Monday.  We have seen the models come in much better agreement over the past few days.  The entire state will be on the cold sector of this system, meaning everyone will see wintry forms of precipitation for the entire event.

SUNDAY:
Overrunning precipitation will begin late Saturday night into Sunday morning.  The "main" event looks to arrive after noon-time on Sunday.  Right now, the big question is precipitation type.  I can't get too detailed until tomorrow, as we need another day for the models to really begin getting a handle on things.  I think the entire state will be cold enough for wintry forms of precipitation out of this event.  Here is the map for Sunday.  Areas near the I-70 corridor north should be all snow, with icing potential across southern Indiana.



SUNDAY NIGHT:
This looks to be when brunt of the storm will occur.  We will see heavy amounts of snow/sleet/ice depending on your location.  

MONDAY:
This is when the storm begins to move out of our area.  Precipitation will transition to all snow before moving out.  




WHAT KIND OF PRECIPITATION CAN I EXPECT FOR MY AREA AND HOW MUCH?  I made out a *preliminary* map showing my thoughts at this time.  This may change a bit over the next couple of days.  Too early to really pinpoint how much icing accumulation may occur in southern Indiana, because so many questions and factors remain.  




I will have another update later this evening.  Have a great day!

Arctic Blast Moving In - Winter Storm This Weekend?

Good evening.  Winter has returned in a big way over the past couple of days, and if you are looking for spring, you won't find it in the forecast anytime soon.  The pattern we have been in all winter refuses to let go.  If you think it is cold now, we have a stronger push of cold pushing in over the next few days which will be downright brutal.  This kind of stuff is crazy for late February.

We will have a streak of snow tonight move across southern Indiana.  I will keep a snow chance for areas south of I-70, with the best chance near the I-64 corridor from Evansville to Louisville.  A coating to 1" of snow could create slick roadways tomorrow morning.  Here is a snapshot of the HRRR model by 11pm this evening:



The next few days will be VERY COLD.  Highs in the teens, with some areas in northern Indiana not even getting out of the single digits thanks to snow cover on the ground.  Mornings will be dangerously cold, with below zero readings north, and single digits to low teens south.  The National Weather Service has issued a wind chill advisory for all areas north of Indianapolis for tomorrow morning, due to forecast wind chills of -15.  The good news is that lots of sunshine will be the rule with no snow threats.  At least we have one thing going for us.  :)  

We have a weak system that could bring light snow Friday night after sunset.  This system is looking weak, but 1" for most areas seems possible.

The main focus of the forecast will be a potential storm for the second half of the weekend into Monday.  We will have a huge temperature gradient over the Ohio Valley, thanks to a stationary front that will be stalling out.  Basically the southern U.S. will be very warm, the north will be very cold, and the Ohio Valley sits right in that boundary zone.  This set-up will spread precipitation through the region during the day Sunday and continuing into Monday.  This could be a big-time mess for Indiana, with significant amounts of snow and ice possible.  I want to quickly discuss what some of the models are showing below, because there is disagreement as is typically the case.  

The GFS (pictured below) paints a mess over Indiana.  It shows everything from a cold rain in far southern Indiana, ice in central Indiana, and heavy snow in far northern Indiana.  This model was farther south with everything yesterday.  


The European and Canadian models are taking the storm quite a ways farther south than the GFS.  I cannot post images of these models, but both bring heavy snow to central and southern Indiana, and keep any ice down in Kentucky.  Right now, I lean toward the Canadian/European models, but cannot discount the GFS solution either.  

At this point, the bottom line is that there is a potential winter storm setting up for the second half of the weekend into early next week.  The track and precipitation type is still very questionable at this time, and will be a few more days before I can get a good handle on any real details.  We will have to watch for the trends in model guidance, and see if we can come to a consensus a little bit.  With a potential winter storm in the forecast, I will post a blog each day to keep you all updated.  Until next time, God bless.

6:07:  Update from National Weather Service in central Illinois:  (Keep in mind the times are in central standard time)



6:03:  Several tornado warnings in Illinois.  Watching closely.



5:58:  Mesoscale discussion from SPC:
SUMMARY...AT LEAST MARGINALLY SEVERE THUNDERSTORMS CAPABLE OF STRONG
   WINDS AND PERHAPS A BRIEF TORNADO WILL CONTINUE ACROSS W-CNTRL IL
   THE NEXT 1-2 HOURS. A WATCH MAY BE NEEDED DOWNSTREAM ACROSS PARTS OF
   E-CNTRL IL INTO CNTRL IND. HOWEVER...THIS AREA WILL CONTINUE TO BE
   MONITORED.

   DISCUSSION...A BROKEN LINE OF STORMS WILL CONTINUE TO TRACK E/NE
   ACROSS W-CNTRL IL THE NEXT COUPLE OF HOURS. THE AIRMASS ACROSS THIS
   AREA IS ON THE FRINGES OF THE BETTER WARM SECTOR FURTHER TO THE
   SOUTH. LATEST OBS SHOW DEWPOINTS HAVE CLIMBED INTO THE UPPER 50S TO
   LOW 60S WITH TEMPERATURES IN THE MID 60S. THIS HAS RESULTED IN
   MODEST MUCAPE VALUES NEAR 1000 J/KG /WHERE SKIES HAVE CLEARED/ PER
   21Z MESOANALYSIS...WITH LOWER VALUES FARTHER EAST UNDER CLOUDY
   SKIES. MIDLEVEL LAPSE RATES NEAR 7-8 DEG C PER KM AND STRONG DEEP
   LAYER SHEAR SHOULD CONTINUE TO SUPPORT A SEVERE THUNDERSTORM THREAT
   AS THE LINE MOVES E/NE. THERE IS SOME POTENTIAL THAT A NEW WW COULD
   BE NEEDED DOWNSTREAM ACROSS E-CNTRL IL INTO CNTRL IND. WHILE STEEP
   MIDLEVEL LAPSE RATES AND STRONG SHEAR WILL CONTINUE TO OVERSPREAD
   THAT AREA...THE QUALITY OF THE WARM SECTOR AIRMASS IS POORER WITH
   DEWPOINTS AND TEMPERATURES IN THE 50S. THIS AREA WILL CONTINUE TO BE
   MONITORED OVER THE NEXT 1-2 HOURS FOR A POSSIBLE WATCH.

MD 125 graphic

5:53:  Here is the LATEST radar.  Line of storms racing eastward from Illinois.  These pack a widespread damaging wind threat, with the highest threat for locations south of I-70.



5:00:  A SEVERE THUNDERSTORM WATCH has been issued for western Indiana until 10pm EST.  Counties included are Clay, Daviess, Greene, Knox, Martin, Owen, Parke, Putnam, Sullivan, Vermillion, and Vigo counties.  SPC says local gusts up to 70MPH possible.
