Well, the winds are starting to calm across the state and it appears the worst is well behind us.  We will see a little more blowing snow tonight as it doesn’t take a whole lot of wind to move that snow around but all things considered conditions will be much better tonight then what we have seen this weekend.  We ended up with some of our strongest winds and worst conditions this morning, that second punch of arctic air we were expecting was extremely cold and of course brought those strong NW winds.  This system proved again that it doesn’t take a whole lot of snow to create a blizzard, most of our snowfall totals came in around 2-4 inches, we had a few spots in the NE corner of the state with 6-7 inches and also some higher totals in SW Minnesota.  Tonight temperatures will plummet as skies stay clear and our winds relax.  We will be seeing another shot of snow and it appears some wind as well on Monday night and Tuesday.Thanks to all of you who sent us weather reports via email and checked out our new video blogs.  Hopefully this is the last blizzard we have to talk about in awhile!We got a ton of pictures of sundogs this weekend, here is a nice one from Ryan…  these are created by the cold air and suspended ice crystals.

The National Weather Service is dropping many of the Blizzard Warnings across the area, although we still have warnings for SE South Dakota, NW Iowa and SW Minnesota.  These will continue overnight tonight for the potential of reduced visibilities do to blowing snow.  We will see conditions improve as the winds die down on Sunday.  The rest of the state has Wind Chill Warnings to deal with overnight tonight and through most of the day tomorrow.  Wind chills will likely be in the 30 to 40 below zero range.  For next week we will be watching another chance of snow late Monday into Tuesday in fact the heaviest snow looks to arrive for the overnight hours on Monday.  The exact path and area of heaviest snow from this system is still up in the air but it does look like someone will get some more accumulating snow and it could be significant.  Then we get a nice break for the Christmas holiday with no major snow expected both Wednesday and Thursday.  I threw in a slight chance of snow on Friday it does look like there will be a storm system somewhere in the upper Midwest but exactly where is still a BIG question mark.

Blizzard Update (Saturday Afternoon)

A quick update because some of the advisories have been adjusted.  The most obvious change was Aberdeen was dropped from the Blizzard Warning and put into a Wind Chill Warning.  One thing we will need to watch is at some point the Blizzard conditions and low visibilities may get a bit better just because the snow may crust over… if that were the case many of these Blizzard Warnings would be dropped as opposed to continueing into Sunday morning.  So we will need to monitor that, either way it isn’t very pleasant out there, and we expect more wind and more cold air with a second arctic blast coming in later today.  I also posted a look at the latest Watches and Warnings below.

Blizzard Update Sat. Morning (Video and Text)

The snow has arrived in eastern South Dakota and will continue through the morning hours.  We are also starting to see the winds pick up back across western and central South Dakota with winds already over 40 mph in the Pierre area as of 5 am.  These strong winds will move into the eastern part of the state this morning creating blizzard conditions in the areas with fresh snow.  The winds and the whiteout conditions will most likely carry through the overnight Saturday before the winds taper down on Sunday.  Along with the dangerous conditions we are seeing some very cold temperatures pour into the state as well.  The cold temperatures and the powerful winds will take windchills into the 35-50 below zero range at times across the state.  Travel in rural areas is being strongly discouraged through most of the day today.  During the day Sunday we will still have bitterly cold temperatures but conditions should gradually improve as the winds die down.  Cold temperatures will stick with us to start the week and we have another shot of snow coming for Tuesday, the models have been extremely inconsistent with this system thus far but it looks like someone will have another decent shot of seeing accumulating snowfall.  There is a little bit of light at the end of the tunnel as a warm up is looking more likely for the end of the week around Christmas Day.
 
If you can, stay in doors today and tonight and keep yourself up to date on KELOLAND-TV or at KELOLAND.com.

If you do have to travel be prepared, it is going to be dangerously cold tonight and tomorrow.  Have a nice evening!

Blizzard approaching

A strong low pressure system is gathering strength in northwestern South Dakota, and will cruise across the state overnight. Winter weather advisories are posted across the area as the snow moves in. All but the northeast tip of South Dakota should see under 4” of new snow. We expect a band of 3-6” amounts from Brookings to the north, and locations Watertown to the north are in a 4-8” forecast bullseye. Sioux Falls should see most of its snow during the morning hours. As you can tell by those amounts, it is not a huge snowstorm – but strong winds will still create visibility problems.
 
We expect the problems to develop tomorrow afternoon, when strong winds will blow around that snow, causing ground blizzard conditions in open areas. That will make travel between cities difficult, if not impossible. Currently we anticipate northwest winds all afternoon in the 20-35 mile per hour range in eastern South Dakota – stronger in the north and west. A blizzard warning is in effect for most of eastern South Dakota, including Chamberlain, Mitchell, Sioux Falls, Huron, Aberdeen, Brookings, Watertown – plus adjoining parts of Minnesota and Iowa.
 
Those winds will bring in very cold air for Sunday, when we expect temperatures to remain below zero all day. Given our continued northwest flow, we anticipate serious wind chill values well below zero, in the range of -20 to -40. Winds should die down by Sunday night, so wind chills and blowing snow should ease by then.Brian Karstens and Tony Barlow will be here in the Storm Center on Saturday morning for additional blizzard coverage.

Winter Storms Update (Thurs. Afternoon)

A pair of storm systems are on our radar for the next few days.  The first one will be moving through tonight especially affecting SE KELOLAND with snow.  The snow has already begun in SW South Dakota and this area of snow will gradually expand and spread eastward for the rest of today.  We are expecting the heaviest snowfall to happen tonight in NW Iowa where about 3-6 inches are possible.  Farther north into SE South Dakota we will look for about 2-4 inches of snow with lesser amounts expected as you go farther northwest.  Because of this snow the Friday morning commute could be a bit tricky in Sioux Falls and NW Iowa. 
Here is the snowfall map and the advisories map (blue shaded counties are in a Winter Weather Advisory, Orange shaded counties are in a Winter Storm Warning and in the Yellow shaded counties in the NE is a Winter Storm Watch for the next system on Saturday.)
 
 
 
Now on to our next system set to arrive for the weekend… this one is still a few days out but it does appear that wind may become an issue with this storm like our storm last week.  We certainly aren’t expecting a repeat of last week, as the winds won’t be as strong but we will have blowing snow to contend with.  The snow will most likely get started out west late Friday we do expect most of our heaviest snowfall to happen during the overnight Friday and thru the first half of the day Saturday.  Snow will likely continue for eastern KELOLAND through the day Saturday but this quick moving system will certainly be out of here by late Saturday or early Sunday.  The winds will then pick up creating ground blizzard like conditions at times.  The heaviest snow right now looks to occur in NE South Dakota although we will be looking a pretty widespread accumulating snow storm and that pocket of heavy snow can still change.  At this time over 6 inches of snow is pretty likely for some areas of the state.  Sunday will be cold and clear but there may again be some blowing snow early in the day before the winds die down.

Stormy Weather Ahead…

We are in the middle of a very stormy period of the weather in the upper Midwest…with 3 potential snowstorms affecting the region before Christmas.  The first will arrive tomorrow afternoon and evening.  The graphic below shows the latest watches, warnings, and advisories across KELOLAND.As of Thursday AM, winter storm watches are in effect for much of NW IA and SW MN.  This means there is the potential for 6" of snow in these areas.  The watches may be adjusted later today. An area of low pressure will develop to our southwest tomorrow morning.  The weather should be fine to start the day Thursday.By Thursday afternoon, snow will develop across KELOLAND.  Light snow is possible for Aberdeen and Pierre where amounts should stay around 2" or less.  Farther to the south, the precipiation may begin as sleet or freezing rain in NW IA…an area shown in light purple on the map above.By Friday AM, the storm will be moving through Iowa with left-over snow and SOME wind.  Winds are a little tricky to forecast right now, but I could easily see 15-25mph NW winds blowing some of the snow.  However, due to the speed of the system, conditions are expected to improve Friday PM.  Another storm is on the way for Saturday and Sunday, however.A powerful cold front will race south Saturday afternoon as snow develops along an inverted trough…the brown dashed line on the map above.  That feature will help lift the air and generate snow.  Given the colder temperatures, snowfall ratios will again be high…so several inches will be possible.  Also, the bitterly cold air will be driven by strong NW winds over 30mph behind the trough.   This scenario would deliver near blizzard conditions across much of KELOLAND late Saturday into Sunday as winds increase the last half of the weekend.  I would keep a close eye on the weather if you plan to travel this weekend.There is a 3rd system down the road by Tuesday that looks similar to these other 2.  Bottom line…it’s looking very busy the next several days.Brian Karstens
