Thundersnow caught on video at Missourinet headquarters

February 21, 2013 By

Thundersnow has been reported in several parts of Missouri during a winter storm that continues to hit Missouri. This video of it was recorded at the Missourinet in Jefferson City, Mo. at Learfield Communications. The lightening flash can be seen at about 15 seconds into the video, and the rumble of thunder was audible for more than a minute after the flash.

Thundersnow is a rare weather occurrence that happens when snow falls instead of rain in a strong upward motion within a cold sector of a front.  A unique aspect of thundersnow is that the snowfall acts as an acoustic suppressor of the thunder, meaning it can be heard many miles away.  Weather experts say thundersnow often produces snowfall rates in the range of 2 to 4 inches per hour.

Winter storm closes I-29 and causes other traffic hazards

December 20, 2012 By

The Missouri Department of Transportation says I-29 in northwest Missouri will remain closed through this afternoon.

The interstate is closed from St. Joseph north to the Iowa border. Transportation Department Maintenance Engineer Tim Chojnacki says the conditions forced plow drivers to stop operations during the overnight.

“Snow has moved out. We’re still seeing some blowing of snow, but we are treating (the highway) now. I don’t have an exact time but I would think sometime this afternoon we could get that reopen.”

On I-29 and in other locations, highways have been closed this morning due to traffic accidents. Chojnacki says once a scene is cleared it can take a while for plows to get the road opened again.

Highway Patrol Captain Tim Hull says those accidents were likely related to the weather.

“They may not have started off weather-related … might have just been a vehicle sliding off the roadway or getting stuck on the roadway and then a crash happening behind them … but a lot of that’s due to being weather-related. There’s a lot of areas where tractor-trailer trucks have become stuck and therefore the roadway is blocked and that was the reason that they closed I-29 down earlier this morning.”

Some motorists became stranded along I-29 by the storm and Hull says troopers are out looking for them and offering assistance. The American Red Cross has also opened some warming centers for stranded motorists and those who have lost power.

“For instance in St. Joseph the Ramada in there at I-29, the First Christian Church in Mound City is the whole county one and the United Methodist Church in Atchison County there in Rockport is the shelter for those people who are stranded and need some place temporary to go to until the highway gets cleared off.”

Chojnacki says most of the roads in north Missouri are covered by some combination of snow, slush and perhaps ice, and the wind is exacerbating that.

“Once the precipitation stops you may still see covered roads for a while until the winds die down and we can be comfortable that those roads will stay mostly clear.”

Both the Transportation Department and the Patrol are urging motorists in northwest Missouri not to get out unless absolutely necessary.

Chojnacki says, “The travel is extremely dangerous. Not just the snow but the blowing wind is creating visibility problems and making it very hazardous to drive. If you do not have to go anywhere, stay home, let us get the roads opened up and things will be better this evening and tomorrow morning.

The Transportation Department is updating its traveler information map with closings and other information, and the Patrol offers its emergency phone numbers for people needing assistance, at (800) 525-5555 or *55 from a cellular phone.

Winter storm on its way to Missouri

December 18, 2012 By

A winter storm will sweep across the midwest Wednesday and into Thursday morning. States north of Missouri will see snowfall, areas south and west of Missouri will get more thunderstorms and rain.

The National Weather Service has updated its snowfall predictions for the storm that is expected to reach Missouri Wednesday evening through Thursday morning.

In Missouri, National Weather Service meteorologist Chris Bowman says the heaviest snowfall will be in northwestern Missouri.

“We’re probably looking on the order of 3 to maybe upwards of 7 inches, maybe 4, upwards of 8 depending on how things play out. Snow amounts are going to be generally lesser as you progress to the south and southeast. For the Kansas City area it looks like a solid 1 to 3 with the heaviest amounts across the northwestern part of the Kansas City metro area, so northern Platte County … into southeastern Jackson County. Over toward Kirksville across northern Missouri probably in the 2 to 4, 3 to 5 inch range for snowfall and then amounts again trail off as you go south, so towards Columbia maybe half an inch of snow?”

The Weather Service says the storm will also pack strong northwest winds of 25 to 35 miles per hour, gusting as high as 45 miles per hour that could cause drifting snow and create “blizzard like” conditions.

“There are going to be periods of time where the strong winds combine with the snow to create visibilities on the order of a quarter-mile or less intermittently through the duration of the storm.

There will also be some sleet or freezing rain as temperatures drop and rain transitions over to snow.

“That’s going to quickly move from west-to-east across mainly northern Missouri … don’t expect to have much in the way of any accumulation from sleet or any frozen precipitation.”

Captain Tim Hull says Missouri didn’t have much of a winter last year, and people tend to forget how to drive on snow and ice.

“We always take this opportunity to remind everybody before we start seeing the snow and ice fly to make sure that they’re prepared … their vehicle’s prepared, they’re mentally prepared, to operate that vehicle in these kinds of driving conditions.”

The Department of Transportation says its crews in Northwest Missouri are ready.

“We’ve got our equipment all calibrated and checked and all of our supplies are stocked and the employees are on alert. We’re basically watching the weather just like everyone else is and we are ready to go when the situation arises.”

Bowman says temperatures in the wake of the system will be much colder on Thursday.

“They’ll struggle through the day on Thursday and maybe by the late afternoon, parts of western Missouri from Kansas City southward to Paola, Kansas or Butler, Missouri might warm up into the lower 30s but elsewhere it’s going to stay in the 20s through the duration of the storm.”

‘Major’ winter storm predicted for later this week

December 17, 2012 By

The National Weather Service says a “very powerful” winter storm could bring some significant snowfall to northern Missouri, Wednesday night and Thursday morning.

Meteorologist Matthew Dukes says the storm will develop beginning tonight over the west coast.

“The best chance for wintry weather in this part of the country looks to align itself from the Kirksville area off to the southwest near Kansas City.”

Accumulations are difficult to predict at this point, but Dukes says several inches of snow is possible in Missouri by the time it quits falling Thursday morning.

The system will reach across the entire Midwest.

Dukes says it will produce, “thunderstorm activity across the Southern Plains and toward the Gulf of Mexico with very heavy and widespread heavy snow expected across portions of Nebraska, Iowa, Minnesota and Wisconsin where the latest estimates could be as much as 5 inches, maybe even up to a foot of snow in some locations and areas north of Missouri.”

The Weather Service says the forecast could change between now and Wednesday, so Missourians are encouraged to keep an eye on it.

“The snowfall forecast could change in some regards especially as we move into northern Missouri and this could have some impacts as well into Central Missouri if things do trend a certain way.”

Weather Service, state agencies urge winter storm prep

November 15, 2012 By

The National Weather Service, the Missouri Department of Health and Senior Services and the State Emergency Management Agency want you and your family to be ready for winter.

While the Weather Service is predicting a warmer than normal December through February in Missouri and dryer than normal conditions in the northern half of the state, that doesn’t rule out any severe winter storms.

Warning Coordination Meteorologist Jim Kramper says, “We’re always going to have variability. You may look at the three months and see things have been drier or warmer than normal … you still can get some cold periods, you can still get very wet periods. We can still get a couple of bad storms. It could be that one month is really bad … cold and wet and lots of snow … but then the other two months are dry and warm. That’s quite possible. You have to be prepared. We’re not going to have three months of constant nice weather.”

Kramper wants Missourians to understand the products his office issues. A winter storm watch is a long-term heads-up that winter weather is possible in an area, telling Missourians to watch the forecast and consider whether they need to change their plans for the affected timeframe.

A winter storm warning is a more immediate call to action.

“Typically within 12 hours, sometimes 24 when we’re really certain about the situation, but a warning means, ‘It’s coming. We really expect it to hit your area if you are in the warning,’ and that is when you really have got to think, ‘Alright, what do I need to do?’”

Life has been halted in recent years in parts of Missouri by ice storms. The Weather Service issues warnings when enough freezing rain is expected to create a quarter-inch of ice accumulation or more.

“That may not seem like a lot … but you get a quarter-inch of ice starting to accumulate on tree branches, power lines, and they can potentially come down … those can be really serious situations.”

Missourians are urged to create family emergency plans and emergency kits, have alternate fuel sources such as firewood or generators and a winter car kit. Find tips on these and other winter preparation at the following websites:
