****WINTER WEATHER ADVISORY THROUGH FRIDAY****
**Overnight update: Snow will continue to develop in bands across the state overnight. We will see the snow start to move into the central sections of the state by 1 AM.
The metro is still looking at 3" to 5" of snow...around 4" is expected in Des Moines.
Up to 6" totals will fall in isolated areas.
You can see the roads are getting slick around the state...leaving Des Moines Dry at Midnight...but the air will become saturated later this morning. Green shows normal roads...blue is wet roadway...pink is completely covered roads... orange shows mostly covered...yellow is partially covered.
Very little wind will come with this storm...roads will be slick, but the roads should remain passable. Road crews should have a good handle on this storm.
Dry weather is still in the forecast Christmas and Sunday.
Have a safe and happy holiday.
You can see that the roads are starting to get slippery in northern Iowa. In central Iowa we are still under normal driving conditions. Great for last-minute shoppers.
The Winter Weather Advisory is still in effect through 6 pm Friday.
The storm is slowing down...and we have seen some dry air moving into the storm. That may give us a break on higher snow totals.
I still think we will have the 3 to 6 inches of snow over the state...in the Metro I am leaning toward 4 to 5 inches.
The snow will continue most of Friday.
We will have more updates on the 10:00 news and our own Megan Brown will be live showing the road conditions in the metro area of Des Moines.
Here are the road conditions as of 5 PM Thursday. Green shows normal driving conditions and blue indicates wet roads. We have seen very decent travel for the whole state...even as we wait for the looming winter storm.
Winter Weather Advisory remains in effect from midnight tonight to 6 PM Friday... snow will spread in from western Iowa tonight...beginning to accumulate in the advisory area around midnight and continuing through the day on Friday. Most of the accumulating snow will fall between midnight and noon on Friday. Snowfall amounts will range from 3 to 7 inches across the advisory area...with the higher amounts coming further northeast toward the Interstate 80 corridor from the Des Moines Metro eastward. Roads will become slick and snow covered. During periods of relatively heavier snowfall visibility may be reduced to below a mile... adding to travel difficulties. A Winter Weather Advisory for snow means that periods of snow will cause travel difficulties. Be prepared for snow covered roads and limited visibility...and use caution while driving.
A winter weather advisory will be in effect for the entire state of Iowa tonight through Friday. Our advisory in Des Moines will start at Midnight and run through 6 PM Christmas Eve.

A winter storm is still on track for central Iowa Thursday afternoon through Friday morning. Heavier amounts of snow are expected late Thursday night through Friday morning.
3" to 5" of new snow will be common over central Iowa...but there will be pockets of 6" to 8".
Expect periods of heavier snow over Des Moines between 1 AM and 6 AM Friday.
This system is slowing down, which means more time for snow to accumulate. There will be very little wind with the storm. No advisories, watches or warnings have been issued for central Iowa. That could change tomorrow.
If you don't have to drive late Thursday through Friday....stay put.
Air travel is not expected to be greatly impacted. There may be delays Thursday night through early Friday....but this will be a slow moving storm that will give road and run-way crews time to move snow.
Again tomorrow night through Friday morning will be the worst time for travel.
It would be better to leave early Thursday....or wait until later in the day Friday.
Coming on the air in just a few minutes...tune in.
49 years ago, on December 22-23 1961, the third (and most severe) winter storm of the month struck Iowa with heavy snow and strong northerly winds bringing the state to a standstill and stranding thousands of travelers. Roadways were littered with abandoned vehicles and those stranded took shelter wherever they could. One farm house near Bondurant sheltered 90 people and another near Griswold housed 57. Near Atlantic the blinding blowing snow caused a 10 car pile-up that injured five people. The Des Moines police department estimated that there were 10,000 abandoned vehicles in the city on the evening of the 22nd. At the Des Moines airport 11.1" of snow was measured on the 22nd, the highest 24-hour amount at that location in more than a decade. Storm totals ranged up to 13.8" at Guthrie Center and at least 15 fatalities and dozens of injuries were attributed to the storm across Iowa. December of 1961 remains the snowiest on record at many locations, although not in statewide average.
Update on our storm.... The snow will start by the afternoon hours tomorrow. The heaviest snow will fall late Thursday night and early Friday. The snow will end by Friday evening. 3" to 5" snow totals area expected over the western 1/2 of Iowa.
Wind will not be a big problem with this storm...and ice is going to stay south of Iowa.
As we have said all week... avoid travel late Thursday through early Friday.
Have a great Wednesday... Ed

Winter Weather Advisory remains in effect for northeastern Iowa until 6 am Tuesday... accumulating snows have all but ended across the advisory area. Occasional flurries or light snow may fall for the rest of the afternoon...but with little or no additional accumulation. However light freezing rain or freezing drizzle may develop early this evening lasting into the night...especially in the Mason City and Waterloo areas. many roads will remain slick and snow covered from previous snows...with additional travel difficulties possible later this evening due to minor ice accumulations. A Winter Weather Advisory for snow means that periods of snow will cause travel difficulties. Be prepared for snow covered roads and limited visibility...and use caution while driving.

Today we will see another very light snow event...flurries running over the state. No Accumulation is expected. Another storm system is going to move to the north of Iowa tomorrow and give us a chance for light snow tomorrow afternoon and evening.
1" to 2" of snow are possible in central Iowa...but 5 inches of new snow is expected along the Iowa/Minnesota border. The best chance for snow is in northeastern Iowa.
The nice folks at the National Weather Service in Johnston have put together an overview of the blizzard that busted up travel plans over the weekend. You can read all about it... and relive the moments right here:

ABSOLUTELY NO TRAVEL IN SIOUX COUNTY TONIGHT. THE IOWA DEPARTMENT OF
TRANSPORTATION HAVE PULLED ALL REMAINING PLOWS AS OF 5 PM FOR THE
REST OF TONIGHT. ALL RURAL ROADS ARE OR SOON WILL BE IMPASSIBLE.
CITY STREETS ARE ALSO IMPASSIBLE. VISIBILITY IS DOWN TO ZERO IN
RURAL AREAS AND LITTLE IMPROVEMENT IN CONDITIONS IS EXPECTED
OVERNIGHT. RESCUE OF ANY STRANDED INDIVIDUALS TONIGHT MAY BE
IMPOSSIBLE. IF YOU DO BECOME STRANDED...STAY WITH YOUR VEHICLE.
The snow pellets that are falling right now over much of the metro look like the stuffing that falls out of a beanbag chair. This is sometimes referred to as graupel. It occurs when warm air is wrapping around the snow storm and colliding with the extremely cold air on the other side of the system.
Stay home if you can tonight. Dangerous road conditions will continue through the early morning hours.
This morning the National Weather Service expanded the Blizzard Warning from northern Iowa through most of the state...including the Des Moines metro.
The snow started to fly in central Iowa around 9 AM...sooner than expected. The cold air was pulled in before the rain could be cut off with drier air that stopped the snow by mid-morning.
At the time of this post...it was still raining in northeast Iowa!
There is a chance for more light snow in central Iowa this afternoon and evening... but the big issue is going to be the wind.
The Northwest wind will whip up to 50 mph. Even walking will be difficult with wind gusts at that level. When you add in light snow and darkness...visibilities will be reduced.
Tonight wind chills will reach -20 to -25. There will be slick spots on roads...but the roads in northern Iowa will be dangerous.
So...we will not see much snow...but the wind...the cold...and visibilities are enough to issue the blizzard warning.
Be careful... if you have to travel...make sure you have your emergency winter kit in your car. Always have your cell phone fully charged.

This is some time-lapse video of November 1, 2009 through February 2010. It was posted on You-Tube from a security camera in Des Moines. It reminds all of us what a crazy winter we were dealing with at this time last year.
Mild temperatures are going to return to Iowa tomorrow and Thursday. Our highs will climb back into the 30s and 40s.
There will be a slight chance for showers and light snow in Des Moines Thursday. This storm will take a northern track and give the counties on the Iowa/Minnesota border a better chance for heavier snow.
Saturday is the focus for our team of meteorologists. This storm will move from the Oklahoma panhandle and sweep through Missouri. It has the potential to give us rain...freezing rain and snow on Saturday.
By Sunday the temperatures will plummet to the teens for highs and lows around zero. Yes...there will be gusty wind behind the storm too.
Travel on Saturday and Sunday could be pretty tough across much of the state.
As always...I will update the storm on the 5, 6, 9 and 10 news tonight and every night. As we get closer to the weekend... the storm path will set up and give us a better idea of exact timing...and who is going to get the best and worst of this weekend storm.
I talked with a guy today who told me his 9-year old was excited about Thursday's storm because the child has not had to go to school on the 9th of December. A winter storm has hit every year when the the 9th of December falls during the week. That happens to be the kid's birthday. Pretty cool...until you have to make-up snow days at the end of the school year.
Stay tuned....and stay informed.... Ed

Extremely Active Atlantic Hurricane Season was a “Gentle Giant” for U.S.
NOAA’s Prediction for Active Season Realized; Slow Eastern Pacific Season Sets Record
According to NOAA the 2010 Atlantic hurricane season, which ends tomorrow, was one of the busiest on record. In contrast, the eastern North Pacific season had the fewest storms on record since the satellite era began.
In the Atlantic Basin a total of 19 named storms formed – tied with 1887 and 1995 for third highest on record. Of those, 12 became hurricanes – tied with 1969 for second highest on record. Five of those reached major hurricane status of Category 3 or higher.
These totals are within the ranges predicted in NOAA’s seasonal outlooks issued on May 27 (14-23 named storms; 8-14 hurricanes; 3-7 major hurricanes) and August 5 (14-20 named storms; 8-12 hurricanes; 4-6 major hurricanes). An average Atlantic season produces 11 named storms, six hurricanes and two major hurricanes.
Large-scale climate features strongly influenced this year’s hurricane activity, as they often do. This year, record warm Atlantic waters, combined with the favorable winds coming off Africa and weak wind shear aided by La Niña energized developing storms. The 2010 season continues the string of active hurricane seasons that began in 1995.
But short-term weather patterns dictate where storms actually travel and in many cases this season, that was away from the United States. The jet stream’s position contributed to warm and dry conditions in the eastern U.S. and acted as a barrier that kept many storms over open water. Also, because many storms formed in the extreme eastern Atlantic, they re-curved back out to sea without threatening land.
“As NOAA forecasters predicted, the Atlantic hurricane season was one of the most active on record, though fortunately most storms avoided the U.S. For that reason, you could say the season was a gentle giant,” said Jack Hayes, Ph.D., director of NOAA’s National Weather Service.
Other parts of the Atlantic basin weren’t as fortunate. Hurricane Tomas brought heavy rain to earthquake-ravaged Haiti, and several storms, including Alex, battered eastern Mexico and Central America with heavy rain, mudslides and deadly flooding.
Though La Niña helped to enhance the Atlantic hurricane season, it also suppressed storms from forming and strengthening in the eastern North Pacific. Of that region’s seven named storms this year, three grew into hurricanes and two of those became major hurricanes. This is the fewest named storms (previous record low was eight in 1977) and the fewest hurricanes (previous record low was four in 1969, 1970, 1977 and 2007) on record since the satellite era began in the mid-1960s. An average eastern North Pacific season produces 15 named storms, nine hurricanes and four major hurricanes.
