The Weather-people are Always Wrong...Maybe Not Always

The National Data Buoy Center has several of these planted all around the world to take current observations at the surface, so we can get a a better idea of what kind of systems are going to be moving onshore.
Their website is extremely interactive, you can click on any of the buoys for the information.
As you can tell, there are several areas where there are no buoys, and thus no data. The big change in ocean observations is coming via jet. Here's a look at NOAA’s Gulfstream IV aircraft. This jet is known best for taking weather observations in Atlantic hurricanes, but now it's going to be taking weather observations over the Pacific Ocean to help improve winter storm forecasts.
(Credit: NOAA)"The highly specialized twin turbofan jet will be stationed at Yokota Air Force Base in Japan through February before repositioning to Honolulu in March. From these locations, the aircraft will be tasked by the National Centers for Environmental Prediction — a division of NOAA’s National Weather Service — to fly into data sparse regions to collect information such as wind speed and direction, pressure, temperature and humidity. This data will be sent via satellite to global operational weather forecasting centers — and fed into sophisticated computer forecast models.
“These flights will help us better observe and understand the current state of the atmosphere over the Pacific, where most of North America’s weather originates, in order to better predict future conditions across the U.S. and Canada three to six days in advance,” said Louis Uccellini, Ph.D., director of the National Centers for Environmental Prediction in Camp Springs, Md.
These computer model improvements will play an essential role in meteorological support for the Winter Olympics in Vancouver in addition to more precise precipitation forecasts along the U.S. West Coast and points further east.
NOAA incorporated the Japan-based missions into its annual Winter Storms Reconnaissance program in early 2009 — flying 332 flight hours and logging miles equivalent to circling the Earth five times. Prior to 2009, missions were flown from Alaska, Hawaii and the U.S. West Coast. By expanding the reach across the International Date Line to Japan, NOAA is essentially pushing farther upstream to observe areas of interest with greater lead times.
These missions showed significant positive impact to global numerical weather prediction models, increasing both accuracy and lead times for high-impact weather events. For example, model forecasts of precipitation amounts improved, on average, 10 to 15 percent.
The high altitude, high speed NOAA Gulfstream IV is based at the NOAA Aircraft Operations Center, located at MacDill Air Force Base in Tampa, Fla.NOAA understands and predicts changes in the Earth's environment, from the depths of the ocean to the surface of the sun, and conserves and manages our coastal and marine resources.

Coldy is Back!
Good news for Thursday though as the winds will settle down and we will see lots of sunshine. But highs are going to struggle, staying in the single digits and low teens.Tuesday, January 26, 2010
Staying Cold

Remember that these temperatures are about 5000 feet in the air. But this gives us a good look at just how cold the surface will be. It is going to be breezy on Wednesday, but that will help temperatures stay a bit warmer because mixing helps warm the atmosphere. But Thursday looks calmer and colder with highs some 20 degrees below average.
Probability of seeing precipitation above or below average 8-14 days from today:
Looks like that temperatures and precipitation will be near normal overall in that time frame. The good news is they (CPC) are not seeing any major storm systems moving through our area in the next 14 days. However, that can change so just keep your fingers crossed and maybe we can get through the next few weeks with no major weather makers.Interstates Opening
But crews are out trying to clear the roads... you can see that 2 hours later (at 7:20 when this picture was captured on the same camera) the drift is gone and there's just a bit of water left where the snow drift was.
Keep tuned onto KDLT, we'll update the closings ticker on the bottom of the screen throughout the day with more updates about the interstates.Monday, January 25, 2010
Blizzard Today




Roads are nearly impassable in many spots because of blowing snow and drifting. Here are the current road conditions.
No travel is advised East of the Orange dashed line so just sit tight wherever you are and wait till morning to venture out.A Blustery, Blustery Day
Things will taper off a little later this evening, but the windy conditions will continue to cause blowing snow and reduce visibilities.Sunday, January 24, 2010
Winds of Change, Really...
Here's the strong Wind gusts:
What we can expect to see Monday morning when the winds should be at their strongest. This is when gusts can exceed 50 mph in all locations.
These winds are bringing in much cooler air also, highs in the teens for Tuesday and Wednesday, but that will seem warm compared to what we can expect for Thursday! Stay warm and enjoy this cold week coming up (the sun will seem nice)!~KDLT Meteorologist Dan Bronis

Whats Ahead

Out towards the west very little rain as this Storm has been an eastern weather maker so far. Mobridge saw less than a tenth inch of rain and Chamberlain is the only town that saw over a quarter inch of rain out towards the west. Some totals were actually very impressive: Sioux Falls, Spencer, Watertown and Sisseton were all over three tenths a inch with some freezing rain; Which caused ice to build up on power lines and trees, but no major damage with this storm, a few power outages in some locals.
Snow will start to fall as the low moves off to the east and we see northwest winds pick up in the area. Light snow fall is expected with the extreme north seeing the most snowfall, four inches tops. Winds will be the main problem in all areas, sustain winds easily topping 40 mph and gusts over 55 possible.
The strongest winds will occur Monday morning but the winds will start Sunday morning and last till Tuesday morning. This model picks up on the strong winds but I do believe they will be stronger then what this shows. Blowing snow will cause low visibilities, and the high winds/ice on the roads can cause cars to slide off and create accidents. Use caution and be prepared!
Were not done yet with this storm, come Tuesday we can see sunny skies and calmer winds. But temperatures will not be very pleasant, highs in the teens for Tuesday and Wednesday.

The Weekender


Here is an updated version of the expected snow and ice accumulations.
So why are we seeing so much rain and freezing rain?? Well here's that answer. Temperatures and moisture have to be just right to form snowflakes. Its actually a very complicated process and they don't come from rain droplets freezing. That's sleet or in the summer time its hail. But when you have snow that develops and starts falling through the atmosphere, the entire column of air that the flake travels through must be below freezing for the flake to reach the ground. Well, when you have air that's about 45 degrees, for example, at 5000 feet, then the flake is going to melt into a raindrop. It will then continue to fall through the atmosphere as a raindrop all the way down to the surface. Well, if the surface happens to be below freezing, then that's when you get freezing rain. If you look at the picture below, of the temperatures at 5000 feet, you should notice something pretty quickly.
The temperatures at 5000 feet this evening are well over freezing. In fact, they are in the upper 40's in some spots. That is what melts the snowflakes and causes our freezing rain. Stay safe out there!!~KDLT Meteorologist Cody Matz
Weekend Update
Here's a radar image of the little activity seen across the region this morning:
There was a little mixed precip located near the South Dakota border and Nebraska, that should start to build up over the next few hours and effect the central portions of the state (Pierre, Mobridge, Aberdeen) with freezing rain and snow, by the mid afternoon hours. The eastern portion of South Dakota won't see much activity until the later afternoon hours and most of that will be rain/freezing rain with temperatures near freezing.
Friday night into Saturday will be the main threat for freezing rain. Accumulations can be expected with a half an inch tops in some locations. That will switch over to snow by Saturday night into Sunday. Be careful on the roads and stay in if it is not a necessity to leave, it will be dangerous with ice build up expected.

Rain in January??
Keep in mind that this model does not like to spread out moisture like it should so places like Aberdeen and Mobridge will likely see more then what this shows but this gives you a general idea of how much we are expecting. Now, looks like many places will see just about every precipitation type imaginable. I just showed you the rain, here is what we are expecting for snow and ice.
So when and where are we going to see all of this happen? Well, I have mentioned before that a picture is worth a thousand words, well this should explain a lot.
Weekend Winter Woes
Keep in mind that part of these totals are rain along with freezing rain, so it's not all going to freeze upon hitting the ground, but when temperatures dip below the freezing mark in the evening and overnight hours, that's when we're going to be worried about re-freezing.This system will affect the other half of our viewing area as well. But temperatures will stay colder and while this system will bring some freezing rain to the northern half of the state, we will see more snow in those areas from this storm from Saturday and Sunday.
Locally, we could see up to a foot of snow in the northwest section of the viewing area and lighter amounts to the south. The reason for lighter amounts down south is because the precip. type in the south, again, is going to be more freezing rain and then changing to snow by Sunday.Make sure you have a good scraper and shovel for this weekend!

The Weekend Storm
This storm will likely bring all four types of precipitation to the area; rain, freezing rain, sleet, and snow. Now, depending on where you are located will depend on exactly how much of each of these types of precipitation you will receive. Here is what we are expecting to be the predominant hazards with this next storm.
All told, some areas could end up with a foot of snow while other ares could get a half inch of freezing rain and then a couple inches of snow. Either way, this weekend will be a travel nightmare.
Probability of receiving 4 or more inches of snow from 6pm Friday through 6pm Saturday:
Probability of receiving at least a quarter inch of freezing rain from 6pm Friday through 6pm Saturday;
Now keep in mind that the last two images do not include the entire storm. So much more can be expected Saturday night and Sunday as well. If you have travel plans this weekend, I would seriously consider having an alternative plan.Wintry Mix Arrives
And boy has it arrived... reports around Sioux City, Iowa have shown 0.4 inches of freezing rain has already accumulated. Sioux Falls saw the freezing rain earlier this morning and now most of the precipitation moving through South Dakota at the moment is falling as snow, with a few areas of sleet being reported as well.
But the big issue will be the roads this morning since most of the southeast saw freezing rain this morning to put a bit of an ice coat onto the roadways. Covering it up with snow could fake some drivers out, so keep your distance from the car in front of you as slippery conditions are likely going to be a common theme all day today. No travel advisories were posted for much of southeast South Dakota earlier this morning but some of those have been lifted so make sure you check out www.safetravelusa.com/sd or call 511 before you decide to take a longer drive. Ice storm warnings are in effect in extreme southeast SD and into Nebraska and Iowa where the most ice accumulation is occuring.Tuesday, January 19, 2010
Caution.... Freezing Rain Ahead
These go through 9pm Wednesday. Those areas can expect a tenth to a quarter of an inch of ice and an inch or so of snow/sleet accumulation. Other areas could see a little freezing drizzle and then some light snow and sleet.
