A nice weekend will now lead into a pretty nasty start to our work week. We will be looking for precipitation to start up through the evening hours Sunday across western South Dakota. With the warm temperatures in place we will look for some rain before temperatures drop and the snow starts probably very early in the day Monday. The best chance for accumulating snowfall will be in southern South Dakota. The system will work its way from west to east early in the day on Monday. There will also be a window where we could see some freezing rain especially early in the day on Monday and in the southeast. Temperatures will continue to drop changing all of the precipitation across the state into snow. Snow showers will continue through the day on Monday, and the system should be out of the area by late Monday. Snow totals will vary quite a bit with this system but we will be looking for a few areas with 2-4 inches especially in southeastern KELOLAND. Otherwise 1-3 inches will be possible across the southern half of the state. This is a challenging system to predict and all of the snowfall totals will depend greatly on when the rain changes over to snow. Either way it is going to be a messy day so plan a little extra time and tune in to KELOLAND This Morning tomorrow at 5 am for the latest. Also feel free to send in any storm reports to email@example.com.

As long as we have breaks in the clouds tonight, and you can stand the cold…lend an eye to the sky tonight for an astronomy sight.
Tonight’s full moon might be a sight to see, as a total lunar eclipse is expected. That’s when the earth’s shadow passes over the moon, don’t worry you still have time, it’s something that won’t start until 7:43 tonight.
At that time, the earth’s shadow will start to partially cover the moon with a total eclipse by 9:01. As this happens, the moon will give a reddish tint. That’s because the sun’s rays, although slight, are still able to illuminate it. As the sun’s rays pass through the earth’s atmosphere, it filters out the blue colored light, the remaining light is the reddish color that bends through the atmosphere causing the moon to glow red. Hopefully clouds will stay out long enough for you to see this eclipse as the next total lunar eclipse will not occur until December, 2010.
Here comes the cold…again!
Temperatures tonight will drop WELL below zero in eastern KELOLAND with lows to the teens and 20s below zero! I wouldn’t be surprised to see a couple of record lows fall tonight across the east…ouch! Here’s a list of some of the record lows for February 13:
ABERDEEN -30° SISSETON -21°
MOBRIDGE -23° SIOUX FALLS -19°
WATERTOWN -22° PIERRE -15°
HURON -22° WINNER -15°
MITCHELL -21° RAPID CITY -6°
We’ll see how low we actually get!
There is some relief in the extended forecast, especially by the weekend. I expect to see moderating temperatures after Wednesday with highs back to the 30s in eastern KELOLAND by Saturday.
Sunday was a strange day across KELOLAND. To be honest with you it reminded me of my college days up on Lake Superior in Ashland, WI. The weather today was very similar to what we saw up there all the time. Especially with the bands of snow and then the crystal clear blue skies. With the lake effect snow that we saw we would have a band of snow come through and drop a couple of inches in a short period of time and then it would clear out and the sun would come out for awhile before another band of snow plowed through. That brutally cold wind was also very similar to the wind we had off Lake Superior. When my wife and I moved south to the Twin Cities, we both commented on the lack of wind. Now it seems that we have moved back into wind territory here in the Dakotas! Another interesting aspect to our weather today was the fact that we had a few reports of thundersnow… one of those reports came from Gary Syme from Plankinton, he also mentioned visibility was less than 100 yards with the heavy snow. Thundersnow is when we have thunder, lightning and snow fall. It is very rare and often means snow is falling extrememly hard. For today’s case Huron picked up about a half inch of snow in less then an hour when one of the heavy bands moved through. I saved a snap shot of one of the heavier bands from south of Plankinton, notice the yellow colors in the radar display signifying some very heavy snow and possibly a little of that thunder and lightning.We also received a few pictures of the near whiteout conditions created by today’s snow from Ricky Bergin in Lake Andes:
Scattered clouds might produce a couple of scattered flurries in eastern KELOLAND, but most locations will stay dry. I expect skies to become mostly cloudy in western South Dakota tonight as the next storm system moves in from the northwest. In fact, WINTER STORM WATCHES are already in effect for North Dakota for tomorrow where 4 to 8 inches of snow might fall along with wind chills of -20 to -40! We expect the snow to move into northern South Dakota tomorrow, but snow amounts will be less…maybe 2-4” for the counties bordering North Dakota. As the system moves southeast through Nebraska, snow will move into southeast KELOLAND tomorrow night. Areas of the southeast might be able to pick up a couple inches Wednesday night into Thursday morning.
Friday morning will be cold with lows below zero in eastern KELOLAND, but a quick “warm-up” will move in for Saturday along with (you guessed it) a chance for snow!
Snowfall continues through much of KELOLAND, especially the southern half of the area. Widespread 1-3 in amounts have already occurred West River, and a few heavier bands of snow are setting up in the southeast part of South Dakota, especially south of I-90. Officially at Sioux Falls airport, over 2" has fallen, but there is a band of heavier snowfall in the southern half of the city. We are still expecting a general 2-5" across the area… but there will be some spots just south of Sioux Falls which can expect 6" before the system moves into northwest Iowa around midnight. Hawarden, IA reports 4", and northwest Iowa will be in that 6" stripe. Snow advisories are posted.Tomorrow looks like an "in-between" day, with a similar system scheduled to come through on Wednesday.-Jay Trobec
We are watching the weather closely this morning as an area of low pressure moves through western SD. Widespread snow mixed with freezing rain has developed in western SD this morning. This was a view from Spearfish after the snow moved through.Look for the snow to continue through the day in eastern KELOLAND. Winter Weather advisories have been issued for much of KELOLAND today for the snow.Look for snowfall rates to increase the next few hours up to 1" per hour or more. The storm prediction center is monitoring our area for this heavy snow as you can see below.The total snowfall today should be heaviest through central and southeast KELOLAND, where 2-5" of snow will be likely by this evening. A smaller band of locally 5+" will be possible within the blue shaded region…perhaps closer to I-90. That’s a trend we will be following through the day.Feel free the report and share the weather in your part of KELOLAND…we always appreciate that too in the comments section below.
For the third Monday in a row we are going to be looking at SNOW. I think it could possibly be a cruel trick being played on the weekend weather guy as I am the one stuck here trying to figure out these tricky, little snow storms. Well, I guess the good news is that I can draw on my experience over the past two Mondays to forecast this one!!! We will continue to see a few areas of light snow tonight, but the main event will move in tomorrow, for most people the snow will start in the morning and the morning commute could again be pretty messy. Snow will continue off and on through the day. For snow totals, 2 to 4 inches looks like a good bet for eastern South Dakota with amounts tapering off a bit as you go south and west. The way this system is moving through some spots could end up with a little more and some isolated areas will see a little less. The snow will also blow around a little bit with gusty south winds. As for the rest of the week temperatures will look to stay on the cool side for eastern South Dakota while central and western South Dakota will look for near normal temperatures. Another shot of snow will move through during the middle of the week on Wednesday and Thursday. Get those shovels ready for round 3!!!Here is an early look at what we could see for snowfall totals:
If you are like me, you probably have spring fever by now. Yes, the days are getting longer and March isn’t so far away. But then the weather maps remind us we still have a long way to go until Spring.I came into work this morning to discover the extended forecast models are hinting at another brush with real cold again by Saturday. Here’s what the GFS (American) model is advertising for Saturday. Those yellow and orange colors to the north are not warm by the way…just the opposite!!By comparison, here’s a look at the European model for the same time frame.If this front comes in advertised, the isobars (solid black lines of equal pressure), would indicate a cold north wind for us too. But if you don’t want to dwell on that too long…here’s the February outlook from CPC.Not warm…Not cold…close to normal??? That would be nice :)Brian Karstens
Quick update from the storm center as of 9:00am…We are still looking at snowbands lifting north on KELOLAND Live Doppler HD. Snow accumulations of 2-3" have already been reported around Sioux Falls. The snow advisory will continue through noon as the biggest band of snow lifts north through the I-90 corridor through 10-11am.Look for slow travel and be aware of that freezing drizzle moving up from the south. The fog is also very thick in central and parts of northeast KELOLAND. Check out safetravelusa.com for more on the road conditions!
