There are 525,948 minutes in a year. How many are spent in a weather warning?

Most of the United States is relatively safe when it comes to severe weather. Of course, we think of Oklahoma and Texas as being prime spots for tornadoes. But a new map shows us the average amount of time spent in a weather warning per county. Daryl Herzmann of Iowa State University released some great maps this week. Take a look!

First, here is the average time spent in a Severe Thunderstorm Warning.
Of course, the higher likelihood for severe thunderstorms lies in the Tornado Alley state of Oklahoma. But notice the maximum over Eastern Tennessee and even Northern Ohio. It may be a little difficult to see the actual location of states because the dark black lines in this map represent the borders of the National Weather Service offices. Here in Northern Illinois and Southern Wisconsin, we are serviced by three different offices, Milwaukee-Sullivan, Quad Cities-Davenport, and Chicago-Romeoville.

Next up, the map showing the average minutes of the year spent in a Tornado Warning:


A few things on this map stand out. First, the larger counties within a tornado-prone zone have a higher chance of being within a warning polygon. Of note is the number of minutes in McLean Co., IL (Bloomington-Normal) which is the largest county in Illinois in bright red compared to Putnam Co., IL (North of Peoria) which is blue.

Daryl went further and took square kilometers into account with the following map. This one is telling! It shows the highest likelihood of a Tornado Warning (not necessarily a full-fledged, on-the-ground tornado) to be in Mississippi.

So, while we may think of Tornado Alley being Texas and Oklahoma, the higher threat of tornadoes may reside in the Deep South…at least looking at the data over the past 20 years.

Finally, for your viewing pleasure? The map for Flash Flood Warnings per county. It’s easy to see the highest probabilities for flash flooding in the past 20 years are in Southern Missouri and in the Desert Southwest.

Flooding Concerns

Even though we’ve got chilly temperatures for the next day or so, minor flooding will cause a few headaches this week. As the ground thawed out and much of our snowpack melted off last week, area creeks and rivers have been on the rise. Luckily, we’ve had a slow thaw and very little rain to agitate our waterways. Nonetheless, creeks and rivers have filled their banks in many spots, even flowing over their banks in others.

As the ice continues to break up, ice jam flooding will be a concern. Ice jam flooding can last a short amount of time or several hours and often comes with very short notice.

Flood warnings and advisories are posted for the Rock River in Ogle, Lee & Whiteside County. Minor flooding is also occurring along the Pecatonica River in Winnebago & Stephenson County. Smaller rivers and creeks have also been affected, including Turtle Creek near Beloit, Yellow Creek near Pearl City and Killbuck Creek near Lindenwood.

March Melt

It happens every March. Temperatures warm up, the sun angle is high, and snow begins to melt. With a snowpack that has been in place for over 90 days, it will take a while for all of it to melt.

Although a major warm-up is not in our immediate future, this week’s high temperatures will be much closer to average than the first week of March. Our average high temperature during the second week of March is in the middle 40s.

Forecast High Temps vs. Average High Temps

Forecast High Temps vs. Average High Temps

In the 7-Day Forecast, we’ve got plenty of temperature ups and downs. A couple of the days will likely touch 50 degrees!

When was the last time we saw 50 degrees? This happened over three months ago on December 4, 2013. Even more impressive is the fact that our high temperature has only cracked the 40 degree mark five times in 2014!

With rapid snowmelt comes the threat for flooding. Thankfully, we won’t see a rapid snowmelt. But even with a gradual melt, we still have to monitor the potential for ice jam flooding on area rivers.

Midwest Mix-Up

TIMINGTonight into tomorrow is going to be an interesting time across the Stateline. Within an 18 hour time frame we could be dealing with the following: snow, rain, freezing rain, thunderstorms, strong wind, dense fog and flooding. Here is a look at the most likely scenario heading into tonight. It is important to note that temperatures will be within a degree or two on either side of 32°, so any slight shift in this system could drastically impact the time frame and amounts of each precip type.

Late tonight a strong area of low pressure will begin to track into our area with temperatures a few degrees shy of 32°. The initial precip will likely be mixed with snow, freezing rain and rain. The best chance for snow and freezing rain will be in far Northern Illinois near the Wisconsin border, and Southern Wisconsin. A few inches of snowfall accumulation early tomorrow morning is in the cards, but any new accumulation will quickly melt heading into the afternoon.

Mid-morning brings us a transition to mainly rain, some of which could be heavy at times, with a few embedded thunderstorms not out of the question. During the time frame of late morning into early afternoon we could see a brief lull in activity with a resurgence of rain for the rest of the afternoon, again with thunderstorm potential. Throughout this process, temperatures will climb well above freezing into the low 40s. Dense fog and localized flooding in low areas due to snow melt is likely.

The evening hours will kick up the wind as the back side of the system slides in and brings with it a shot of colder air and the potential for a few additional inches of snowfall.

Again, I stress that the smallest shift in storm track could greatly increase or decrease snowfall potential and accumulation especially heading into tomorrow morning. Stay tuned for more updates! – Greg

Destination: Warmer Weather

I wish there was a way for the weather to be instantaneously warm. But that’s not going to be the case. We are forecasting much warmer temperatures by the end of February. But there are several bumps in the road, just in the next week!

rough1Here’s a look at the snow events in the next five days. On Wednesday, we’ll see about an inch of snowfall. It’s not going to be that big of a deal, so long as you drive slow and allow extra time. Most of this will fall in the early afternoon hours.

More snow flurries are in the forecast for Thursday, but little/no accumulation is expected. A bigger snow system is possible for Saturday as the models show a vigorous Alberta Clipper moving in from the northwest. We’ll continue to watch this in the next few days. Right now, it looks like a 3-6 inch snow…but a lot depends on the eventual track. Models will resolve their differences in the next 24-48 hours.



2Next bump on “Warming Trend Road” is a quick shot of cold air coming in Friday. While it won’t be extreme cold…or nearly the scope of the cold that brought us down to -21° today, it will pause our warming trend. There are some indications we’ll be in the teens for highs, however will stick with the 20s due to stronger sunshine and a warmer start-up temperature Friday morning. Friday night will be mighty chilly if you’re planning a night on the town. We’ll dip to around 0° with high pressure overhead.



We could be warm enough for some rain to mix into our next system Monday. But with temperatures at the surface at or below freezing, there could be some ice accumulation. It’s way out there, but we’ll have to watch closely as our ground is still frozen solid, there’s quite a bit of snow on the ground, and rain could cause short-term flooding. Unfortunately, flooding will become a significant concern in the next few weeks.

Weather Pattern Flip Flop

de3epfreezeThe cold weather pattern that began well before Christmas is showing signs of easing up. While temperatures will dip to -16° Tuesday morning, it looks like we’ll have a remarkable warming trend after that.

The maps to the left show the overall change in jet stream pattern in the next two weeks. Instead of a northwest-southeast orientation of the jet, we’ll have a southwest-northeast orientation. This will bring much milder temps to the Upper Midwest. 30s and 40s are likely for much of next week.

However, don’t pray TOO hard for warmth. Think of the fact we have snow on top of a very frozen ground. If we don’t gradually melt off the snow, we will see serious flooding beginning in a few weeks. So, let’s hope this thaw happens over a longer period of time so we don’t see extreme flooding.

But if you don’t have flood insurance and you live in a flood plain, you might want to think about getting it so you’re covered before the water rises! Of course, we’ll keep you updated on flooding potential in the next few weeks. -Eric

Wintry cocktail coming on Friday


We’ve got a few challenges to deal with on Friday. But in the whole realm of everything we’ve seen this winter, this is an easy one to live with. In the morning, we’ll have a few hours of very light freezing drizzle. Just a little can cause problems so be careful especially on the first few steps in your sidewalk.

As temperatures rise into the middle 30s by mid-morning, we’ll see all rain. It looks like we’ll get about a half inch of rain with some higher amounts east and south of Rockford. This will cause some roads to flood, especially where the rainwater has nowhere to go. So watch out, especially in the right lanes.

In addition, we’ll be keeping our eyes on the river levels. In the next few days, we could have some significant fluxuations due to ice jam flooding. Be careful if you live near or work around any of our rivers! -Eric temptracker

Tropical Storm Flossie

2Hawaiians are bracing themselves as Tropical Storm Flossie makes its approach. The storm has weakened in the past 12 hours, but as of 11am CST it still has a sustained wind speed of 45mph with gusts as high as 60mph. The Big Island and Maui are expected to see the brunt of the storm with the likelihood of 18 foot waves, flash flooding, mudslides, tornadoes and waterspouts. Despite the weakening of the system, many signs point to Flossie remaining a tropical storm until we head into Wednesday. -Greg

Rivers remain high for the 4th of July

Were you planning on hitting the river this Fourth of July? I hope not. Almost every river is near or above flood stage, except for the Kishwaukee. Please stay off all high/flooding rivers and if you’re going to enjoy the “Mighty Kish” please wear a life vest. -Eric
