Why were there tornadoes today?

sfctmp_nWhen we ran our 13Severe Weather Index model yesterday, it showed us a bullseye around St. Louis for today. Indeed, they got it. There are numerous reports of injuries and fatalities today…perhaps because people don’t expect this level of activity at the end of December.

Today’s set-up included dewpoints in the middle 50s across much of the Mid-Mississippi River Valley. In addition, a high level of instability existed (with colder air aloft) which allowed thunderstorms to erupt, even before dawn across parts of Oklahoma and Arkansas. A strong cold front (with a thirty degree temperature spread across it). Check out the current temperature map which shows the incredible temperature difference!

bettycrockeringredientsStill, these factors aren’t enough to produce the wild weather day we observed. The frosting on the cake is the jetstream high above. An unusually strong speed max was located in Missouri today, the likes of which we usually only see in the spring months.

This set-up is very similar to the event in early January 2008 when tornadoes were spawned in Northern Illinois and Southern Wisconsin. The thing that saved us this go-around was the fact it took an extra day to melt the snow. Had we melted it all yesterday instead of today, we more than likely would’ve had tornadoes here.

While Tornado Watches remain in effect for parts of downstate Illinois and Indiana, the threat will wane significantly with the onset of night. Tornadoes will still remain possible well south into parts of Mississippi and Louisiana tonight and could affect revelers in New Orleans and Mobile. -ES

Bye bye snowpack!

snowmeltTake a look at this animation from our friends at the Milwaukee NWS that shows the dwindling snowpack across Wisconsin (Click to animate). While warmer temperatures are usually to blame, this go around was caused quickly by the combination of warm temperatures and warm dewpoints. -ES

New Year’s Eve tornado threat

breaking_news31

12:41pm- The storm that prompted a Tornado Warning for areas north of Bloomington has significantly weakened. This tells us that the farthest north extent of the severe weather risk will likely only be I-80 this afternoon. However, as warm air continues to advect into the region, we will still have a potential for non-severe thunderstorms, mainly over our eastern and southern counties. -ES

12:20pm – The storm prompting a Tornado Warning for Central Illinois is about to move out of the current Tornado Watch. A new Tornado Watch will likely be issued for the southern suburbs of Chicago, points southward. Again, this will be close but will remain out of our coverage area. Dense Fog Advisories are plotted in gray on this real-time map. The new Tornado Watch (should it be issued will show up on the bottom right portion of the map. -ES

12:15pm – Tornado threat continues for the St. Louis metro area as there are numerous areas where tornadoes could form. This complex of storms will continue to race northeast and could possibly affect the Springfield and Decatur areas early this afternoon. We’ll update you as we get information concerning damage. radarstlIn the meantime, please visit the following websites for information: www.kmov.com www.ksdk.com www.fox2now.com -ES

11:50am – Tornado Warnings are in effect for Central Illinois, affecting parts of I-39 between LaSalle and Bloomington.

As we forecast last night on 13News, these storms will affect the I-55 corridor today and stay south of our coverage area. Tornadic storms are currently affecting the St. Louis area and will move toward Springfield, Decatur, and Champaign this afternoon.

We will remain somewhat stable today although a few thunderstorms will be possible. The Storm Prediction Center has a high-end slight risk for Central Illinois, southward. Tornado Watches are lining up from Illinois to the Gulf Coast with a possibility of today being a tornado outbreak. Be alert if you’re in the green-outlined area! -ESactivity_loopradar

Arkansas Tornado

out28According to our sister station KARK-TV: early this morning, three people died after a tornado slammed through the town of Cincinnati, AR, which is near the Oklahoma border. The tornado hit sometime around 6 a.m. causing lots of damage in the downtown area and through most of the western portion of the county. According to National Weather Service, there is extensive damage in the area including a brick home that was destroyed, several damaged vehicles, a volunteer fire department facility and two barns have been destroyed.  The NWS issued tornado warnings in the early morning hours for northwest Arkansas and southwest Missouri as the storms approached the area.

Chicago Fog Bowl

bearseaglesfogfog_bowl_eagles_bears_1988On this day in 1988, the Chicago Bears and the Philadelphia Eagles played a game at Soldier Field. A heavy, dense fog rolled over the field about midway through the second quarter causing visibility to drop to 20 yards or less and stayed for the rest of the game. The fog, as you can imagine, caused many challenges for the players as well as the fans, which could not see where the ball was, let alone the score. Television and radio announcers found it nearly impossible to call the plays being made, because they could not see the players. Those on the field complained they couldn’t see the sidelines, where the first-down maker was or where the field goal posts were located. Due to the bizarre weather phenomenon, the game was officially labeled the “Fog Bowl.” The winner of the “Fog Bowl” was the Bears 20-12.
It is somewhat ironic that we have to deal with the same foggy condition on the 22nd anniversary of the “Fog Bowl.”

Cold front coming!

exactrack1A cold front is touching off some showers (and perhaps a few rumbles) in Eastern Iowa right now. This could seriously throw a wrench into our planned 50° temperatures on Friday. The present placement of the front is about as far east as it was supposed to go. However, the front sprouted showers and these showers are moving northeast. The showers will in turn nudge the front along to the east during the overnight hours.

So, the big question is where will this front be tomorrow. If it’s east of us, we’ll only have high temperatures in the upper 30s. If it stalls to our west along the Mississippi River some middle 50s will be possible. In all likelihood it’ll probably end up right over us which will keep northern and western locales cold while our southeastern sections stay mild and soupy. Note: all of the precip will stay ahead of the front so if it comes through, we’ll be dry during the day on Friday.

Meteorologist Aaron Brackett will have the analysis in the morning. Have a great night! -ES

100 car pile-up in North Dakota

breaking_news3Blizzard conditions across much of North Dakota have caused authorities to close most of I-94 and almost all of I-29 completely tonight.

According to KFYR-TV a one hundred car pile-up occurred on I-94 this afternoon west of Fargo. A semi-truck slid partially off the road which then caused a chain reaction accident as dozens of cars and trucks crashed into one another. Emergency crews had a difficult time getting to the stranded motorists due to zero visibility. Several people were injured, but none of those are life-threatening.

Zero visibility has caused Department of Transportation officials to call off snow removal equipment until at least Friday morning.

Stories like these should be reason enough to have a winter emergency kit in your car. Do you have one just in case?

Thunderstorms for New Year’s Eve!

capecape2While severe thunderstorms aren’t in the forecast for us, downstate Illinois could see a round of severe thunderstorms tomorrow afternoon with damaging wind and even an isolated tornado.

Our Severe Weather Index places some feisty storms from the Quad Cities, southward toward Quincy early in the afternoon. The highest probability of severe will be near St. Louis, southward where more instability is located. Storms will move northeast, mainly along the I-55 corridor through the day. Storms will weaken as they move into a more stable environment north of I-80. So while a few rumbles are certainly possible for New Year’s Eve evening, the severe storm threat will thankfully stay southeast. -ES
