Warm & Windy

A Wind Advisory is now in effect for Lee and DeKalb counties through 6pm.


This time of year the warmth and wind go hand-in-hand.  While temperatures today will reach the middle 50s, sustained winds from the south will reach 25 mph and gusts could top 40 mph later this afternoon making travel on east/west roads a little difficult at times.  While we still have some of that white stuff on the ground the snow depth is fairly shallow so the 50s are a good bet today while locations just to our south could reach the 60s due to lack of snow cover.  Whatever snow we had left from yesterday will likely be gone by tonight.

Due to the low relative humidity and strong southerly winds, Red Flag Warnings have been issued across the Plains and middle Mississippi River Valley.

Illinois Severe Weather Preparedness Week: How Prepared Are You?

We all remember the 2011 severe weather season and how active it was, but unfortunately 2012 is already off to a record start.  This has some concerned as to what the rest of the year will be like.

As we all know tornadoes can occur at any time of day and any time of year and that's why it's so important for you and your family to be prepared. 

From the Chicago NWS:

****Remember, sirens are outdoor warning systems and should not be your primary method of receiving tornado warnings.****


Severe weather in the form of tornadoes, lightning, flash foods, damaging winds, and destructive hail strike Illinois each spring, summer and fall, sometimes with incredible violence.



2011 was a devastating year for tornadoes in the United States. There were more than 1700 tornadoes nationwide, including 59 killer tornadoes which claimed 550 lives. It was the deadliest year for tornadoes since 1925. The 2012 tornado season got off to a fast and early start with a rash of tornadoes in the overnight and morning hours of February 28 and 29 from Kansas and southern Missouri, eastward into southern Indiana, southern Illinois and Kentucky. An EF4 tornado struck the town of Harrisburg, Illinois in the predawn hours, killing 6 and injuring around 100. An even deadlier tornado outbreak was seen across the Ohio and Tennessee Valleys on Friday, March 2, with over two dozen fatalities.

The National Weather Service urges you to develop a safety plan for use at your home, workplace, school, vehicle, and for outdoor activities. Be aware of severe weather safety rules. Planning ahead and knowing what to do might save your life. For more information visit the Illinois Emergency Management Agency web site at http://ready.illinois.gov/.


Tornado Watches and Warnings
Tornadoes are the most destructive storms that occur in Illinois. Being prepared for a tornado can save your life.

A tornado watch means severe thunderstorms and tornadoes are possible in your area over the next few hours. Be prepared.

A tornado warning means a tornado has been sighted by a trained storm spotter, or intense rotation that will likely produce a tornado has been detected by Doppler radar. Get to a place of safety immediately.

Statewide Tornado Drill Tuesday March 6

Tuesday March 6 at 1000 AM CST a test tornado warning will be issued for all Illinois counties. Many locations in Illinois will also test sirens on Tuesday morning.


The test warnings will be disseminated through NOAA Weather Radio with the tone alarm and SAME codes. Many commercial radio and TV stations will participate by passing along the test tornado warning. The test will be postponed to Wednesday March 7 if severe weather threatens.


This would be a good time to review your severe weather procedures or conduct a tornado drill at your school or place of business.

Tornado Safety

In Illinois, most tornadoes occur from April through June, during the mid afternoon through early evening hours, but they can occur anytime of day and any month of the year. Last year, Illinois had 73 tornadoes, well above the 30-year average of 46 tornadoes. In 2006, Illinois set a state record with 124 tornadoes. Illinois ranks fifth in the nation in tornado frequency per square mile. There were no fatalities and only 8 injuries from tornadoes in 2011. The strongest tornado, rated EF3, struck near Girard in Macoupin County on April 19.

When a tornado threatens, you may only have seconds to save yourself and your family. Have a preparedness plan for your home, school, and workplace. Know where to find the best tornado shelter.


In a home, go to the basement and get under the stairwell, or under a heavy piece of furniture. If there is no basement, go to an interior closet, hall or bathroom on the lowest floor and stay away from windows. Cover your head with pillows or sofa cushions.


In schools, hospitals, churches and office buildings, go to small interior rooms or interior halls on the lowest floor. Long corridors with doors or windows on the end can act as wind tunnels. Stay away from windows. Avoid large open areas with free span roofs such as gymnasiums and cafeteria.


In steel and concrete high rise buildings, it is not necessary to get to the lowest floor, but go to interior halls, bathrooms or closets. Stay away from windows.


In shopping centers, avoid large open areas and glass. Seek shelter in bathrooms, small interior spaces and behind counters. Do not attempt to escape in your vehicle.


Abandon mobile homes and vehicles for a nearby reinforced building. As a last resort lie flat in a ditch. Do not seek shelter under an overpass.

Lightning Safety


Lightning is the most frequent important weather threat to personal safety during the thunderstorm season. Keep these lightning safety tips in mind;


Plan ahead and avoid dangerous lightning situations. Check the latest forecast before going outdoors for extended periods. Watch for storms and seek shelter indoors when storms approach.


Lightning often strikes the tallest object. If caught outdoors during a storm, don’t stand next to tall trees or power poles. And don’t be out in an open area where you may be the tallest object. A closed, hard top metal vehicle is safe in a thunderstorm. An open structure such as a picnic shelter will keep you dry but it will not protect you from lightning.


If boating or swimming, get out of the water when storms approach and seek shelter indoors.


Avoid using electrical appliances, corded telephones and metal plumbing when indoors during a thunderstorm. It is okay to use a cell phone or cordless phone.


The best way to stay safe from lightning is to go indoors as soon as there is a threat. A good way to remember that is “When thunder roars, go indoors!”

Look for more information during national lightning safety awareness week June 24 through June 30 or visit www.lightningsafety.noaa.gov.


Flash Flood Safety

A flash flood is a rapid rise in creeks and streams, or serious urban flooding, caused by heavy rain from thunderstorms, which poses a threat to life and property. Floods and flash floods kill more people nationwide than any other storm hazard in most years. In Illinois, most flash floods occur in July and August, and they often occur at night. Last year, one man died in flooding in Sangamon County, Illinois when he drove around a barricade into a flooded road on June 18. Three people died in flooding that occurred in Jo Daviess County July 27 and 28.


About half of all flash flood related deaths occur in vehicles. Don’t drive through flooded roads, especially if the water is moving rapidly. Flooded or washed out roads are especially difficult to see at night. Remember, “Turn around, don't drown!”


Don’t let children play near storm drains, creeks or flooded areas.

If you live near a creek or stream, evacuate to higher ground if water rises rapidly or if a flash flood warning is issued.

Urban flooding is also potentially dangerous. Heavy rain that results in flooding of streets, viaducts and underpasses in an urban area can pose a threat to motorists. Heavy rain can also result in flooded basements, ponding of water in low spots and rapid flooding of drainage ditches and storm sewer systems.

Severe Thunderstorm Safety


Severe thunderstorms pose a threat to life and property. They produce damaging downburst winds of around 60 mph or greater, and/or large destructive hail, one inch in diameter or greater. Flooding rains, frequent cloud to ground lightning, and tornadoes are also possible in severe thunderstorms.


A severe thunderstorm watch means severe thunderstorms are possible in the next few hours. Be prepared.


A severe thunderstorm warning means a thunderstorm capable of causing property damage and injury has been sighted or detected by radar. Go indoors and stay away from windows.


Damaging straight line or downburst winds from a thunderstorm can do as much damage as a weak to moderate tornado, so take severe thunderstorm warnings seriously.


Very large hail, golf ball or larger, is not only very destructive, but it occurs with the most violent of storms.

NOAA Weather Radio – All Hazards and National Weather Service Web Pages


Today, a better understanding of tornadoes, new technology such as Doppler radar, faster communications, and better Skywarn storm spotting networks, allow meteorologists to provide more accurate and timely warnings for destructive tornadoes and severe storms. But in order for the warnings to be effective, people must receive the warnings in a timely manner and take proper actions to protect themselves.

The best way to receive severe weather watches and warnings is with a tone alert NOAA Weather Radio – All Hazards. A weather radio will give you severe weather information direct from your local National Weather Service office. Watches and warnings are preceded by a tone alert that can automatically activate your radio and get your attention with a high pitched alarm – even if storms hit in the middle of the night. S.A.M.E equipped radios can be programmed to only alert you to watches and warnings for a specific county, or group of counties.

In addition, the radios can alert you to a non-weather emergency such as a hazardous material spill or child abduction.

Weather radios can be purchased at many electronics and department stores for 30 to 80 dollars. They are highly recommended for homes, schools, hospitals, nursing homes, day care centers, and businesses. You should also take one along when boating or camping. More information about weather radio can be found at www.nws.noaa.gov/nwr/index.html

A Major Warm Up on the Way by Tuesday

An  Alberta Clipper system slipped by to the west of the Stateline on Sunday afternoon and is located near the southern tip of Illinois tonight.   It produced 1" to 3" from northwest Iowa into west central Illinois.  The low is on its way to southern Virginia by daybreak Monday morning with weak Canadian high pressure following in behind the departing system making for a mostly sunny, but relatively cool day with a high around 37 degrees. The Canadian high will shift to Kentucky by evening as a pattern shift takes place. A strong pressure gradient will develop between the high and a strong low over Montana. A surface warm front will develop from eastern Kansas to eastern Monana. Brisk southwesterly winds will develop across the Stateline overnight preventing the temperatures from dropping any lower than the upper 20's. The strong southwesterly winds of 20-30 mph with gusts to 35 mph will buffet the area on Tuesday.  Nearly all of the recent snows will be melted by sunset Tuesday.  The source region for the air will be the southern plains where humidity levels are relatively low, so it will be much warmer under mostly sunny skies. The afternoon high on Tuesday will be in the middle  to upper 50's.  By early Wednesday morning a cold front will stretch from northwestern Wisconsin southwest through Omaha, Nebraska. The strong southwesterly winds will continue through the day, and Gulf of Mexico moisture will be drawn northward into the mid west. Skies will become mostly cloudy, and scattered showers will develop during the afternoon. It will be very mild with an afternoon high near 60 degrees. Showers will be likely on Wednesday night as the cold front works its way across northern Illinois. The cold front will be east of Chicago and St. Louis by daybreak on Thursday. There is a slight chance of some lingering showers in the morning. Skies will become partly cloudy, and it will be cooler with a high temperature in the middle 40's. A sprawling Pacific type of high pressure will take charge of Stateline weather by Thursday night dropping temperatures to near 30 degrees. On Friday the high will be located over the central and northern plains providing a very nice day with mostly sunny skies in the Greater Rockford with a  northerly breeze, and an afternoon high around 43 degrees. The high will dominate upper midwestern weather next Saturday as it moves to northern lower Michigan providing mostly sunny skies, and afternoon temperatures in the  middle 40's.    On Sunday the high will shift into eastern Pennsylvania, but will maintain a ridge westward through northern Illinois.  Winds will be southeasterly, and the afternoon temperature will rise into the low 50's.

Synopsis/Forecast for Sunday March 4th (Updated 6:30 am cst)

A convergence/trough line that has been dropping southward across southern Wisconsin overnight will go stationary today across extreme southern Lake Michigan into northeast Illinois today.  More snow showers are possible closer to Lake Michigan because of lake enhancement as the winds turn northeasterly along the lakeshore.  There could be some snow showers over the Stateline but very little snow is expected.  Flurries are more likely. 

A fast moving system will drop southeast today from the northern plains to near Cairo, Illinois by 6 pm this evening.  It will lay down a band of snow from northwest to southeast Iowa, and from west central Illinois to southeast Illinois.  The band could well be several inches, but will be well to the west and southwest of the Stateline area.

Today:  Cloudy with some snow flurries.  A chance of snow showers this morning.
High:  32 degrees
Wind: Northwest 5-8 mph

Snow Showers Have Developed

A slow moving cold front across southern Wisconsin, and the disturbance associated with it have generated areas of snow showers across northern Illinois as of 2 am cst.  Looking at National Service Weather radars across Wisconsin, northern Illinois, eastern Iowa, and southeastern Minnesota indicate patchy areas of snow showers generally moving slowly east/southeast.  There has been a dusting already of powdery snow.  Given the development over the past couple of hours, snow showers can be expected off and on for the rest of the night into Sunday morning.  Minor accumulations from a dusting to less than 1" are possible in localized areas.

A Cold Weekend to Start off March

The storm that spun up killer tornadoes in Indiana, Kentucky, Ohio, and Alabama on Friday, and a sloppy wet snow of 2" to 4" across the Stateline has departed, kicked into high gear, and is located over central Quebec in eastern Canada this evening.  A re-enforcing cold front/trough of low pressure is dropping southward across Wisconsin this evening.  It will remain cloudy ovenight with a chance of some snow showers and flurries after midnight.  The overnight low will be in the low to middle 20's with a west/northwest wind from  6 to 14 mph.  It will remain cloudy to mostly cloudy and cold on Sunday with a chance of snow showers.  The afternoon high will only be in the low 30's along with a northwest wind betrween 5 and 10 mph.  The average temperature for March 4th is 40 degrees.  A new Alberta Clipper system will pass to the west of the Stateline on Sunday.  Right now it looks as if it will be far enough west not to produce any system snows across north central Illinois.  However, it will produce accumulating snows across Iowa, to our west, but if the track changes, and moves a little further to the east, it could graze parts of north cental Illinois will some fresh snow. That low pressure area will move from near St. Louis at supper time on Sunday to Virginia by daybreak Monday morning with weak Canadian high pressure following in behind the departing system making for a mostly sunny, but relatively cool day with a high around 37 degrees.  The Canadian high will shift to Kentucky by evening as a pattern shift takes place.  A strong pressure gradient will develop between the high and a strong low over Montana.  A surface warm front will develop from eastern Kansas to eastern Monana.  Brisk southwesterly winds will develop across the Stateline overnight preventing the temperatures from dropping any lower than the upper 20's.  The strong southwesterly winds will continue on Tuesday.  The source region for the air will be the southern plains where humidity levels are relatively low, so it will be much warmer under mostly sunny skies.  The afternoon high on Tuesday will be in the middle 50's.  By early Wewdnesday morning a cold front will stretch from northwestern Wisconsin southwest through Omaha, Nebraska.  The strong southwesterly winds will continue through the day, and Gulf of Mexico moisture will be drawn northward into the mid west.  Skies will become mostly cloudy, and scattered showers will develop during the afternoon.  It will be very mild with an afternoon high near 60 degrees.  Showers will be likely on Wednesday night, and there could be some thunderstorms, too, as the cold front works its way across northern Illinois. The cold front will be east of Chicago and St. Louis by daybreak on Thursday.  There is a slight chance of some lingering showers in the morning. Skies will become partly cloudy, and it will be cooler with a high temperature in the middle 40's.  A sprawling Pacific type of high pressure will take charge of Stateline weather by Thursday night dropping tempertures to near 30 degrees.  On Friday the high will be located over the central plains providing a very nice day with  mostly sunny skies in the Greater Rockford, a gentle northwesterly breeze, and an afternoon high around 43 degrees.  The high will dominate upper midwestern weather next Saturday with mostly sunny skies, and afternoon temperatures in the low to middle 40's.
